[0002] With the continuous development of electronic products, the application of touch screens is becoming increasingly widespread. Dispensing and pressure holding, as a key process in their production, directly affects the performance and lifespan of the product. While production lines have achieved partial automation through integrated feeding, assembly, pressure holding, and conveying systems, improving production efficiency to some extent, shortcomings remain in the turnover of pressure holding fixtures. This results in low fixture turnover efficiency, affecting the smoothness of the overall production process. Utility Model Content

[0058] Please refer to Figures 1 to 13 This application embodiment of a pressure-holding storage device includes a first conveying device 1, a second conveying device 2, a bottom mold return device 31, a top cover return device 32, a storage conveying device 4, a loading device 5, and a unloading device 6. The first conveying device 1 and the second conveying device 2 are spaced apart in a first horizontal direction. The conveying direction of the first conveying device 1 is the forward direction of the second horizontal direction, and the conveying direction of the second conveying device 2 is the reverse direction of the second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. The bottom mold return device 31, the top cover return device 32, and the storage conveying device 4 are sequentially arranged between the first conveying device 1 and the second conveying device 2 along the forward direction of the second horizontal direction. The loading device 5 is mounted on the first conveying device 1, and the unloading device 6 is mounted on the second conveying device 2. The bottom mold return device 31 is used to convey the bottom mold 210 from the second conveying device 2 to the first conveying device 1. The loading device 5 is used to transport the workpiece 100 onto the bottom mold 210 of the first conveying device 1. The loading device 5 is also used to transport the top cover 220 on the top cover return device 32 onto the bottom mold 210 of the first conveying device 1 to form a pressure-holding fixture 200 containing the workpiece 100. The loading device 5 is also used to transport the pressure-holding fixture 200 on the first conveying device 1 onto the storage conveying device 4. The unloading device 6 is used to transport the pressure-holding fixture 200 on the storage conveying device 4 onto the second conveying device 2. The unloading device 6 is also used to transport the top cover 220 of the pressure-holding fixture 200 on the second conveying device 2 onto the top cover return device 32. The unloading device 6 is also used to transport the workpiece 100 on the second conveying device 2 onto the workpiece output device 8.

[0059] In this embodiment, the first conveying device 1 and the second conveying device 2 form a reverse conveying cooperation, and a bottom mold return device 31, an upper cover return device 32 and a storage conveying device 4 are set between them. Together with the feeding device 5 and the unloading device 6, the independent return of the bottom mold 210 and the upper cover 220 is realized, which effectively improves the turnover efficiency of the pressure holding fixture 200 and thus improves the overall production efficiency.

[0060] As an example, the workflow of the pressure-holding storage equipment is as follows: the bottom mold return device 31 transports the bottom mold 210 on the second conveying device 2 to the first conveying device 1; the loading device 5 transports the workpiece 100 to the bottom mold 210 of the first conveying device 1; the loading device 5 transports the upper cover 220 on the upper cover return device 32 to the bottom mold 210 of the first conveying device 1, the upper cover 220 and the bottom mold 210 are closed to form a pressure-holding fixture 200, the workpiece 100 is housed in the pressure-holding fixture 200 and pressure-holding is performed in the pressure-holding fixture 200; the loading device 5 transports the workpiece 100 to the bottom mold 210 of the first conveying device 1. The workpiece is transported to the storage and conveying device 4; the storage and conveying device 4 conveys the pressure-holding fixture 200 in the forward direction along the first horizontal direction; the unloading device 6 moves the pressure-holding fixture 200 on the storage and conveying device 4 to the second conveying device 2; the unloading device 6 removes the upper cover 220 of the pressure-holding fixture 200 on the second conveying device 2 to expose the pressure-held workpiece 100, and moves the upper cover 220 to the upper cover return device 32; the unloading device 6 moves the pressure-held workpiece 100 on the second conveying device 2 to the workpiece output device 8; the second conveying device 2 conveys the bottom mold 210 to the bottom mold return device 31, and so on.

[0061] As an example, workpiece 100 can be a mid-frame and a touch screen pre-attached together. It should be noted that in other embodiments, workpiece 100 can also be other products, which can be set according to the actual situation, and will not be elaborated here.

[0062] In some implementation methods, please refer to Figure 2 and Figure 7 The pressure-holding storage equipment also includes a first workpiece input device 71, which is located on the opposite side of the first conveying device 1 in the first horizontal direction. That is, the first workpiece input device 71 is located on the side of the first conveying device 1 away from the bottom mold return device 31, the top cover return device 32, and the storage conveying device 4 in the first horizontal direction. Furthermore, the first workpiece input device 71 is located between the bottom mold return device 31 and the top cover return device 32 in the second horizontal direction. The first workpiece input device 71 is used to convey the workpiece 100 in the forward direction along the first horizontal direction. The loading device 5 is used to transfer the workpiece 100 from the first workpiece input device 71 onto the first conveying device 1.

[0063] In this embodiment, the first workpiece input device 71 is positioned to avoid spatial interference with the bottom mold return device 31, the top cover return device 32, and the storage and conveying device 4. Furthermore, by conveying the workpiece 100 forward along the first horizontal direction, it cooperates with the feeding device 5 to realize the transfer of the workpiece 100 to the first conveying device 1, thereby optimizing the feeding path of the workpiece 100 and reducing the overall space occupied by the equipment.

[0064] As one implementation method, please refer to Figure 2 and Figure 7 The pressure-holding storage equipment also includes at least one second workpiece input device 72, which is spaced apart from the first workpiece input device 71 in a second horizontal direction. The second workpiece input device 72 is used to convey the workpiece 100 in the forward direction along the first horizontal direction. The pressure-holding storage equipment also includes a handling device 73, which is mounted above the first workpiece input device 71 and the second workpiece input device 72. The handling device 73 is used to handle the workpiece 100 on the second workpiece input device 72 onto the first workpiece input device 71. After the workpiece 100 output from the previous process arrives at the first workpiece input device 71, the loading device 5 can directly handle the workpiece 100 on the first workpiece input device 71 onto the first conveying device 1. After the workpiece 100 output from the previous process arrives at the second workpiece input device 72, the handling device 73 handles the workpiece 100 on the second workpiece input device 72 onto the first workpiece input device 71, and the loading device 5 then handles the workpiece 100 on the first workpiece input device 71 onto the first conveying device 1.

[0065] In this embodiment, the conveying device 73 can realize the conveying and transfer of workpiece 100 between the second workpiece input device 72 and the first workpiece input device 71, expand the input capacity of workpiece 100 to adapt to different batch production needs, ensure the orderly transfer of multi-source workpiece 100 to the first conveying device 1, and further improve the overall operating efficiency of the equipment.

[0066] As an example, the sum of the number of the first workpiece input device 71 and the number of the second workpiece input device 72 is the same as the number of the output lines of the previous process and is set in a one-to-one correspondence. It can directly receive the workpieces 100 transported by multiple output lines of the previous process without the need for additional transfer or diversion mechanisms. It effectively adapts to the previous production rhythm of multiple parallel lines and improves the coordination efficiency and process smoothness of the entire production line.

[0067] In some examples, the number of output lines from the previous process is two. Accordingly, the pressure holding storage equipment includes a first workpiece input device 71 and a second workpiece input device 72. The first workpiece input device 71 is connected to the output end of one of the output lines, and the second workpiece input device 72 is connected to the output end of the other output line.

[0068] As one implementation method, please refer to Figure 2 and Figure 7The pressure-holding storage equipment also includes a first visual inspection device 74, which comprises multiple first image acquisition units 741. The number of first image acquisition units 741 is equal to the sum of the number of first workpiece input devices 71 and second workpiece input devices 72. The first image acquisition units 741 are positioned above the corresponding first workpiece input device 71 or the corresponding second workpiece input device 72 to acquire images of the workpiece 100. As an example, the workpiece 100 can be a mid-frame and a touch screen that are pre-attached together. The first image acquisition unit 741 can acquire images of the workpiece 100, and then a control device electrically connected to the first image acquisition unit 741 determines whether the orientation of the camera on the workpiece 100 in the image is the same as a preset orientation.

[0069] As an example, please refer to Figure 2 and Figure 7 The pressure-holding storage equipment includes a first workpiece input device 71 and a second workpiece input device 72. The first visual inspection device 74 includes two first image acquisition devices 741, one of which is correspondingly set with the first workpiece input device 71 and is used to acquire images of the workpiece 100 on the first workpiece input device 71, and the other of which is correspondingly set with the second workpiece input device 72 and is used to acquire images of the workpiece 100 on the second workpiece input device 72.

[0070] As one implementation method, please refer to Figure 2 and Figure 7 The first visual inspection device 74 may also include a first light source 742, the light beam provided by the first light source 742 can illuminate the workpiece 100 conveyed by the first workpiece input device 71 and the second workpiece input device 72, thereby improving the clarity of the image acquired by the first image acquisition device 741.

[0071] In some implementation methods, please refer to Figure 4 and Figure 8 The pressure-holding storage equipment also includes a workpiece output device 8, which is located on the positive side of the second conveying device 2 in the first horizontal direction. That is, the workpiece output device 8 is located on the side of the second conveying device 2 away from the bottom mold return device 31, the top cover return device 32, and the storage conveying device 4 in the first horizontal direction. Furthermore, the workpiece output device 8 is located between the bottom mold return device 31 and the top cover return device 32 in the second horizontal direction. The workpiece output device 8 is used to convey the workpiece 100 after pressure holding in the positive direction of the first horizontal direction.

[0072] In this embodiment, the workpiece output device 8 is positioned to avoid spatial conflicts with the bottom mold return device 31, the top cover return device 32, and the storage and conveying device 4. Furthermore, by coordinating the workpiece output device 8, which completes the pressure-holding workpiece 100 by forward conveying along the first horizontal direction, with the material unloading device 6, the transition of the workpiece 100 from the second conveying device 2 to the output is achieved. This allows the pressure-holding workpiece 100 to be conveyed to the next process, further improving the continuity of the production process and the space utilization rate.

[0073] As one implementation method, please refer to Figure 4 , Figure 5 and Figure 8 The pressure-holding storage equipment also includes a flipping device 9, which is mounted above the workpiece output device 8. The flipping device 9 is used to flip the workpiece 100 on the workpiece output device 8 by 180° around a first straight line, which is parallel to a second horizontal direction. As an example, in the next process, the screen of the workpiece 100 needs to face upward and the camera needs to face downward, while the workpiece 100 output by the second conveying device 2 has the screen facing downward and the camera facing upward. The flipping device 9 can flip the workpiece 100 by 180° so that the workpiece 100 meets the requirements of the next process.

[0074] In this embodiment, the flipping device 9 is mounted above the workpiece output device 8 and can flip the workpiece 100 180° around a first straight line parallel to the second horizontal direction. This allows it to adapt to the placement requirements of the next process for the workpiece 100 (such as making the camera face down). There is no need to manually adjust the orientation of the workpiece 100, which avoids the efficiency reduction and pollution risk caused by manual intervention. This ensures that the workpiece 100 is transported in a state that meets the requirements of the subsequent process, further improving the synergy between the equipment and the upstream and downstream processes and the overall automation level of production.

[0075] As an example, please refer to Figure 5The flipping device 9 includes a lifting drive assembly 91, a clamping assembly 92, and two flipping assemblies 93. The output end of the lifting drive assembly 91 can extend and retract in the vertical direction. The clamping assembly 92 includes two clamping members 921 and a clamping drive member 922. The clamping drive member 922 is fixed to the output end of the lifting drive assembly 91, and the two clamping members 921 are disposed at the output end of the clamping drive member 922. As an example, the two clamping members 921 can be arranged opposite each other in the second horizontal direction. The two flipping assemblies 93 are disposed one-to-one at the ends of the two clamping members 921 away from the clamping drive member 922. The flipping assembly 93 includes a flipping drive member 931 and a fixing block 932. The flipping drive member 931 is fixed to the clamping member 921, and the fixing block 932 is fixed to the output end of the flipping drive member 931. The fixing blocks 932 of the two flipping assemblies 93 are arranged opposite each other. After workpiece 100 is conveyed by workpiece output device 8 to the lower end of flipping device 9, lifting drive assembly 91 drives clamping assembly 92 to move downwards. Then, clamping drive member 922 drives two clamping members 921 to move towards each other, so that two fixing blocks 932 cooperate to clamp workpiece 100. After clamping workpiece 100, lifting drive assembly 91 drives clamping assembly 92 to rise to the first position, giving workpiece 100 sufficient space to flip and avoid interference with workpiece output device 8 during flipping. After clamping assembly 92 is in the first position, the two flipping drive members 931 simultaneously drive the corresponding fixing blocks 932 to flip 180° around the first straight line, so that workpiece 100 clamped between the two fixing blocks 932 flips 180° around the first straight line. Then, lifting drive assembly 91 drives clamping assembly 92 to descend until workpiece 100 is supported on workpiece output device 8. Next, clamping drive member 922 drives two clamping members 921 to move in opposite directions to release workpiece 100. Finally, the workpiece output device 8 continues to transport the workpiece 100 in the first horizontal direction.

[0076] In some examples, the lifting drive assembly 91 can be a linear cylinder, the clamping drive 922 can be a gripper cylinder, and the tilting drive 931 can be a rotary cylinder.

[0077] In some implementation methods, please refer to Figure 2 and Figure 7The first conveying device 1 includes a first conveying mechanism 11, a second conveying mechanism 12, and a third conveying mechanism 13, which are sequentially arranged and connected as a single unit in the positive direction of the second horizontal direction. The input directions of the first conveying mechanism 11, the second conveying mechanism 12, and the third conveying mechanism 13 are the same, all in the positive direction of the second horizontal direction. That is, the input end of the second conveying mechanism 12 is connected to the output end of the first conveying mechanism 11, and the output end of the second conveying mechanism 12 is connected to the input end of the third conveying mechanism 13. Specifically, the first conveying mechanism 11 is located at the output end of the bottom mold return device 31, the second conveying mechanism 12 is located at the output end of the top cover return device 32, and the third conveying mechanism 13 is located at the input end of the storage conveying device 4. The loading device 5 includes a first handling mechanism 51, a second handling mechanism 52, and a third handling mechanism 53, which are sequentially arranged in the positive direction of the second horizontal direction. The first transport mechanism 51 is located above the first conveying mechanism 11, and is used to transport the workpiece 100 onto the bottom mold 210 conveyed by the first conveying mechanism 11. The second transport mechanism 52 is located above the second conveying mechanism 12, and is used to transport the upper cover 220 on the upper cover return device 32 onto the bottom mold 210 on the second conveying mechanism 12, so that the upper cover 220 and the bottom mold 210 are closed to form a pressure-holding fixture 200 for receiving the workpiece 100. The third transport mechanism 53 is located above the third conveying mechanism 13, and is used to transport the pressure-holding fixture 200 on the third conveying mechanism 13 onto the storage conveying device 4.

[0078] In this embodiment, the first conveying mechanism 11, the second conveying mechanism 12, and the third conveying mechanism 13 are sequentially connected in the positive direction of the second horizontal direction. Together with the first handling mechanism 51, the second handling mechanism 52, and the third handling mechanism 53 arranged in the positive direction of the second horizontal direction, the segmented collaborative operation of loading the bottom mold 210, placing the workpiece 100, closing the top cover 220, and transferring the pressure holding fixture 200 to the storage and conveying device 4 is realized. This not only ensures the accurate assembly of the bottom mold 210, the workpiece 100, and the top cover 220, but also improves the assembly efficiency and transfer accuracy of the pressure holding fixture 200 through each handling mechanism.

[0079] In some implementation methods, please refer to Figure 4 and Figure 8The second conveying device 2 includes a fourth conveying mechanism 21, a fifth conveying mechanism 22, and a sixth conveying mechanism 23. These three mechanisms are arranged sequentially in opposite directions along the second horizontal direction and connected as a single unit. Their input directions are the same, all in opposite directions along the second horizontal direction. Specifically, the input end of the fifth conveying mechanism 22 connects to the output end of the fourth conveying mechanism 21, and the output end of the fifth conveying mechanism 22 connects to the input end of the sixth conveying mechanism 23. The fourth conveying mechanism 21 is located at the output end of the storage conveying device 4, the fifth conveying mechanism 22 is located at the input end of the top cover return device 32, and the sixth conveying mechanism 23 is located at the input end of the bottom mold return device 31. The unloading device 6 includes a fourth handling mechanism 61, a fifth handling mechanism 62, and a sixth handling mechanism 63. These mechanisms are arranged sequentially in opposite directions along the second horizontal direction. The fourth transport mechanism 61 is located above the fourth conveying mechanism 21 and is used to transport the pressure-holding fixture 200 on the storage conveying device 4 to the fourth conveying mechanism 21. The fifth transport mechanism 62 is located above the fifth conveying mechanism 22 and is used to transport the upper cover 220 of the pressure-holding fixture 200 on the fifth conveying mechanism 22 to the upper cover return device 32. The sixth transport mechanism 63 is located above the sixth conveying mechanism 23 and is used to transport the workpiece 100 on the sixth conveying mechanism 23 to the workpiece output device 8.

[0080] In this embodiment, the fourth conveying mechanism 21, the fifth conveying mechanism 22, and the sixth conveying mechanism 23 are sequentially connected and cooperate with the fourth handling mechanism 61, the fifth handling mechanism 62, and the sixth handling mechanism 63, which are arranged in reverse order along the second horizontal direction. This realizes the segmented operation of receiving the pressure-holding fixture 200 from the storage and conveying device 4, disassembling and returning the upper cover 220, outputting the workpiece 100, and returning the bottom mold 210. This improves the return efficiency of the upper cover 220, the return efficiency of the bottom mold 210, and the smoothness of the output of the workpiece 100, effectively avoids process interference, further optimizes the automated disassembly and material recycling process of the equipment, and improves the overall operating efficiency.

[0081] In one implementation, at least one of the first conveying mechanism 11, the second conveying mechanism 12, the third conveying mechanism 13, the fourth conveying mechanism 21, the fifth conveying mechanism 22, and the sixth conveying mechanism 23 is a conveying mechanism 1000. Please refer to... Figure 9 and Figure 10The conveying mechanism 1000 includes two conveyor belts 1100, a positioning assembly 1200, and a lifting drive assembly 1300. The two conveyor belts 1100 are spaced apart in a first horizontal direction and cooperate to convey the bottom mold 210. The positioning assembly 1200 is located between the two conveyor belts 1100 and includes two positioning elements 1210 and a positioning drive element 1220. The two positioning elements 1210 are arranged opposite each other in a second horizontal direction and are located at the output end of the positioning drive element 1220. The positioning drive element 1220 drives the two positioning elements 1210 to move towards each other in the second horizontal direction, thereby clamping the base and positioning the bottom mold 210 in the second horizontal direction. The positioning drive element 1220 also drives the two positioning elements 1210 to move away from each other in the second horizontal direction, thereby releasing the bottom mold 210. The output end of the lifting drive assembly 1300 is fixed to the positioning drive component 1220. The lifting drive assembly 1300 is used to drive the positioning assembly 1200 and the bottom mold 210 on the positioning assembly 1200 to rise so that the bottom mold 210 is separated from the conveyor belt 1100. The lifting drive assembly 1300 is also used to drive the positioning assembly 1200 and the bottom mold 210 on the positioning assembly 1200 to fall so that the bottom mold 210 is supported on the conveyor belt 1100.

[0082] In this embodiment, the positioning drive 1220 drives two positioning members 1210 to move towards each other in the second horizontal direction to clamp the bottom mold 210, which can achieve precise positioning of the bottom mold 210, facilitating the operation of the corresponding conveying mechanism. The lifting drive assembly 1300 can detach the bottom mold 210 from the conveyor belt 1100, avoiding collisions or friction between the conveying mechanism and the conveyor belt 1100 during operation, thus affecting the service life and tension of the conveyor belt 1100.

[0083] It should be noted that the bottom mold 210 conveyed by the conveying mechanism 1000 can be a single bottom mold 210, or the bottom mold 210 can be a bottom mold 210 carrying the workpiece 100, or the bottom mold 210 can be a bottom mold 210 that is closed with the upper cover 220 to form a pressure-holding fixture 200, depending on the actual situation. As an example, when the conveying mechanism 1000 is the second conveying mechanism 12, before the second transport mechanism 52 closes the upper cover 220 onto the bottom mold 210, the bottom mold 210 conveyed, positioned and lifted by the second conveying mechanism 12 is the bottom mold 210 carrying the workpiece 100. After the second transport mechanism 52 closes the upper cover 220 onto the bottom mold 210, the second conveying mechanism 12 conveys, positions and lowers not only the bottom mold 210, but also the workpiece 100 and the upper cover 220 closed on the bottom mold 210.

[0084] As an example, the workflow of the conveying mechanism 1000 can be as follows: When the conveyor belt 1100 transports the bottom mold 210 to the area below the corresponding transport mechanism, the lifting drive assembly 1300 extends, and the positioning assembly 1200, carrying the bottom mold 210, moves upward until it separates from the conveyor belt 1100. Then, the two positioning members 1210 move towards each other in the second horizontal direction to clamp the bottom mold 210, and the corresponding transport mechanism begins to work. After the corresponding transport mechanism completes its work, the two positioning members 1210 move away from each other in the second horizontal direction to release the bottom mold 210. Then, the lifting drive assembly 1300 retracts, allowing the bottom mold 210 to be placed back onto the conveyor belt 1100, and the two conveyor belts 1100 cooperate to continue transporting the bottom mold 210 along their transport direction.

[0085] It should be noted that in other embodiments, before the conveying mechanism works, the positioning drive component 1220 can first drive the two positioning components 1210 to position the bottom mold 210, and then the lifting drive component 1300 can lift it up. This can be set according to the actual situation, and will not be elaborated here.

[0086] In some examples, the lifting drive assembly 1300 can be a linear cylinder. The positioning drive 1220 can be a gripper cylinder, with two positioning elements 1210 respectively located at the two output ends of the positioning drive 1220. Alternatively, the positioning drive 1220 can be a linear cylinder, with two positioning drive elements 1220 and positioning elements 1210 arranged in a one-to-one correspondence. The positioning element 1210 is fixed to the output end of the corresponding positioning drive element 1220. This can be configured according to the actual situation, and will not be elaborated here.

[0087] In some examples, the first conveying mechanism 11, the second conveying mechanism 12, the third conveying mechanism 13, the fourth conveying mechanism 21, the fifth conveying mechanism 22, and the sixth conveying mechanism 23 are all conveying mechanism 1000. It should be noted that in other embodiments, at least one of the first conveying mechanism 11, the second conveying mechanism 12, the third conveying mechanism 13, the fourth conveying mechanism 21, the fifth conveying mechanism 22, and the sixth conveying mechanism 23 may have a structure different from that of conveying mechanism 1000. For example, a conveying mechanism with a structure different from that of conveying mechanism 1000 may only include the conveyor belt 1100 and exclude the positioning component 1200 and the lifting drive component 1300. This can be set according to the actual situation and will not be elaborated here.

[0088] As one implementation method, please refer to Figure 11The upper cover 220 includes an upper cover body portion 221 and two latching portions 222. The two latching portions 222 are symmetrically arranged on both sides of the upper cover body portion 221. The middle portion of each latching portion 222 is rotatably connected to the upper cover body portion 221. An elastic element is connected between the upper end of each latching portion 222 and the upper cover body portion 221, and the elastic element is compressed between the latching portion 222 and the upper cover body portion 221. Each latching portion 222 can rotate relative to the upper cover body portion 221 to a second position. In the second position, the lower end of the latching portion 222 is used to engage with the bottom mold 210. The latching portion 222 can also rotate relative to the upper cover body portion 221 to... Figure 11 In the third position shown, the lower end of the latching part 222 in the third position is separated from the bottom mold 210. Therefore, in addition to transporting the top cover 220, the fifth transport mechanism 62 also needs to release the latching relationship between the top cover 220 and the bottom mold 210 before transporting the top cover 220. Please refer to... Figure 12 and Figure 13 The fifth conveying mechanism 62 includes a first moving module 621, a second moving module 622, a first opening module 623, and two second opening modules 624. The first moving module 621 includes a first output end 6211 that can move along a first horizontal direction. The second moving module 622 is fixed to the first output end 6211 and includes a second output end 6221 that can move vertically relative to the first output end 6211. The first opening module 623 includes two first grippers 6231 and a first opening drive member 6232. The first opening drive member 6232 is fixed to the second output end 6221. The two first grippers 6231 are arranged opposite each other in the first horizontal direction, and the two first grippers 6231 are respectively fixed to the output end of the first opening drive member 6232. The first opening drive member 6232 is used to drive the two first grippers 6231 to move towards each other in the first horizontal direction to clamp the upper end of the latching part 222, causing the latching part 222 to rotate to the third position. The first opening drive member 6232 is also used to drive the two first grippers 6231 to move away from each other in the first horizontal direction to release the upper end of the latching part 222, so that the latching part 222 can rotate to the second position under the action of the elastic member. Two second opening modules 624 are symmetrically arranged on both sides of the first opening module 623 in the second horizontal direction. The second opening module 624 includes two second grippers 6241 and a second opening drive member 6242. The second opening drive member 6242 is fixed to the second output end 6221. The two second grippers 6241 are arranged opposite each other in the first horizontal direction, and the two second grippers 6241 are respectively fixed to the output end of the second opening drive member 6242. The second opening drive member 6242 is used to drive the two second grippers 6241 to move toward each other in the first horizontal direction to clamp the upper cover body 221. The second opening drive member 6242 is also used to drive the two second grippers 6241 to move away from each other in the first horizontal direction to release the upper cover body 221.

[0089] As an example, the working principle of the fifth conveying mechanism 62 is as follows: After the fifth conveying mechanism 22 conveys the pressure-holding fixture 200 to the area below the fifth conveying mechanism 62, the first output end 6211 of the first moving module 621 moves to the top of the pressure-holding fixture 200, and the second output end 6221 moves downward until the two first grippers 6231 are located on both sides of the latching part 222 and the four second grippers 6241 are respectively disposed on both sides of the upper cover body part 221. Then, the first opening drive member 6232 drives the two first grippers 6231 to move towards each other to clamp the upper end of the latching part 222, causing the latching part 222 to rotate to... Figure 11 In the third position shown, the latch 222 in the third position separates from the bottom mold 210. The second opening drive member 6242 drives the two corresponding second grippers 6241 to move towards each other and clamp the upper cover body 221. The second output end 6221 of the second moving module 622 drives the upper cover 220 to move upward and separate from the bottom mold 210. Then, the first output end 6211 of the first moving module 621 drives the upper cover 220 to move above the input end of the upper cover return device 32. Then, the second output end 6221 of the second moving module 622 drives the upper cover 220 to move downward and rest on the upper cover return device 32. The first opening drive member 6232 and the second opening drive member 6242 work to drive the first gripper 6231 and the second gripper 6241 to release the upper cover 220.

[0090] As an example, the first moving module 621 can be a linear slide module, the second moving module 622 can be a linear slide module, the first opening drive 6232 can be a gripper cylinder, and the second opening drive 6242 can be a gripper cylinder.

[0091] In some embodiments, the structure of the second transport mechanism 52 can be the same as that of the fifth transport mechanism 62, which facilitates the smooth engagement of the upper cover 220 and the bottom mold 210. In other embodiments, the second transport mechanism 52 can also have other structures.

[0092] In some implementations, the third handling mechanism 53 and the fourth handling mechanism 61 may be robotic arms.

[0093] In some embodiments, the structures of the first transport mechanism 51 and the sixth transport mechanism 63 can be similar to those of the fifth transport mechanism 62. For example, the difference between the first transport mechanism 51 and the sixth transport mechanism 63 and the fifth transport mechanism 62 is that the first transport mechanism 51 and the sixth transport mechanism 63 do not include the first opening module 623. In other embodiments, the first transport mechanism 51 and the sixth transport mechanism 63 can also use adsorption to fix the workpiece 100, for example, by replacing the second opening module 624 and the first opening module 623 with a suction cup module, or by replacing the first opening module 623 with a suction cup module.

[0094] It should be noted that in other embodiments, the first transport mechanism 51, the second transport mechanism 52, the third transport mechanism 53, the fourth transport mechanism 61, the fifth transport mechanism 62 and the sixth transport mechanism 63 can also be other structures, which can be set according to the actual situation, and will not be elaborated here.

[0095] In some implementation methods, please refer to Figure 2 , Figure 4 as well as Figures 6 to 8 The bottom mold return device 31 includes a bottom mold return conveying mechanism 311, a first rotary conveying mechanism 312, and a second rotary conveying mechanism 313. The bottom mold return conveying mechanism 311 is used to convey the bottom mold 210 in the reverse direction along a first horizontal direction. The first rotary conveying mechanism 312 is located between the output end of the bottom mold return conveying mechanism 311 and the input end of the first conveying device 1. The first rotary conveying mechanism 312 can rotate to a fourth position or a fifth position around a second straight line extending in a vertical direction. The first rotary conveying mechanism 312 in the fourth position is connected to the output end of the bottom mold return conveying mechanism 311, and the conveying direction of the first rotary conveying mechanism 312 in the fourth position is the reverse of the first horizontal direction. The first rotary conveying mechanism 312 in the fifth position is connected to the input end of the first conveying device 1, and the conveying direction of the first rotary conveying mechanism 312 in the fifth position is the forward of the second horizontal direction. The second rotary conveying mechanism 313 is located between the input end of the bottom mold return conveying mechanism 311 and the output end of the second conveying device 2. The second rotary conveying mechanism 313 can rotate around a third straight line extending in the vertical direction to a sixth position or a seventh position. The second rotary conveying mechanism 313 in the sixth position is connected to the output end of the second conveying device 2, and the conveying direction of the second rotary conveying mechanism 313 in the sixth position is the opposite of the second horizontal direction. The second rotary conveying mechanism 313 in the seventh position is connected to the input end of the bottom mold return conveying mechanism 311, and the conveying direction of the second rotary conveying mechanism 313 in the seventh position is the opposite of the first horizontal direction.

[0096] In this embodiment, after the second rotary conveying mechanism 313 in the sixth position is connected to the output end of the second conveying device 2, the second conveying device 2 conveys the bottom mold 210 to the second rotary conveying mechanism 313. Then, the second rotary conveying mechanism 313 rotates to the seventh position and is connected to the input end of the bottom mold return conveying mechanism 311. The second rotary conveying mechanism 313 in the seventh position conveys the bottom mold 210 to the bottom mold return conveying mechanism 311 in the reverse direction of the first horizontal direction. Then, the bottom mold return conveying mechanism 311 continues to convey the bottom mold 210 to the first rotary conveying mechanism 312 in the fourth position in the reverse direction of the first horizontal direction. Then, the first rotary conveying mechanism 312 rotates to the fifth position and is connected to the input end of the first conveying device 1. Then, the first rotary conveying mechanism 312 conveys the bottom mold 210 to the first conveying device 1 in the forward direction of the second horizontal direction. In this embodiment, the bottom mold return device 31, through the bottom mold return conveying mechanism 311 and the first rotary conveying mechanism 312 and the second rotary conveying mechanism 313 which can rotate around the vertical direction, realizes the turning conveying of the bottom mold 210 between the output end of the second conveying device 2 and the input end of the first conveying device 1. The whole process does not require the participation of the handling mechanism, which reduces the positioning error and time loss caused by the handling action, avoids additional space occupation, ensures the continuity and efficiency of the bottom mold 210 return, and further improves the structural compactness of the equipment.

[0097] It should be noted that this embodiment does not limit the specific structure of the first rotary conveying mechanism 312 and the second rotary conveying mechanism 313. Standard models sold on the market can be used, or they can be customized as needed, which will not be elaborated here.

[0098] As one implementation method, please refer to Figure 2 , Figure 3 and Figure 7The pressure-holding storage equipment also includes a second visual inspection device 314 and a bottom mold defective part output device 315. The bottom mold defective part output device 315 is used for reverse conveying of the bottom mold 210 along the first horizontal direction. The first rotary conveying mechanism 312, located in the fourth position, is connected between the bottom mold defective part output device 315 and the bottom mold return conveying mechanism 311. The second visual inspection device 314 includes a second image acquisition device 3141, which is mounted above the output end of the bottom mold return conveying mechanism 311 to acquire images of the bottom mold 210. As an example, the second image acquisition device 3141 can acquire images of the bottom mold 210, and then a control device electrically connected to the second image acquisition device 3141 can determine whether the orientation of the area of ​​the bottom mold 210 used to house the camera in the image matches a preset orientation. If the orientation matches the preset orientation, the bottom mold 210 is conveyed to the first rotary conveyor 312 in the fourth position. Then, the first rotary conveyor 312 rotates to the fifth position and aligns with the input end of the first conveying device 1. The first rotary conveyor 312 then conveys the bottom mold 210 onto the first conveying device 1 in the positive direction of the second horizontal direction. If the orientation does not match the preset orientation, the bottom mold 210 is conveyed to the first rotary conveyor 312 in the fourth position. Then, the first rotary conveyor 312 conveys the bottom mold 210 onto the bottom mold defective part output device 315 in the reverse direction of the first horizontal direction.

[0099] As an example, please refer to Figure 3 The second visual inspection device 314 may also include a second light source 3142, which is arranged around the second image acquisition device 3141. The light beam provided by the second light source 3142 can illuminate the workpiece 100 conveyed by the bottom mold return conveying mechanism 311, thereby improving the clarity of the image acquired by the second image acquisition device 3141.

[0100] In some embodiments, the width of the conveyor belt of the storage and conveying device 4 in the second horizontal direction is several times the width of the pressure-holding fixture 200. Therefore, when the pressure-holding fixture 200 is placed on the storage and conveying device 4, multiple pressure-holding fixtures 200 can be arranged sequentially along the second horizontal direction, or they can be stacked (multiple pressure-holding fixtures 200 are stacked sequentially along the vertical direction). Thus, not only can the pressure-holding fixture 200 be conveyed along the first horizontal direction, but the storage and conveying device 4 can also perform stacked storage of the pressure-holding fixtures 200. Since the closed upper cover 220 and bottom mold 210 apply a certain pressure to the workpiece 100, the pressure-holding storage equipment may not include a pressure-holding machine. It should be noted that in other embodiments, the pressure-holding storage equipment may also include a pressure-holding machine, which can be located on one side of the storage and conveying device. The pressure-holding fixture can be moved by a handling device such as a robot arm. This can be set according to the actual situation and will not be elaborated here.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
