Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to an unloaded bracket and a plate unloaded platform. Background Technology

[0002] The stamping process typically involves four steps: drawing, trimming, flanging, and forming / punching. To ensure the machinability of all dies, the equipment is equipped with four worktables to accommodate these steps. With the increasing intensification and simplification of die design and advancements in processing technology, the production steps for some products have been reduced, potentially requiring only two or three steps. This means that dies on some worktables are used less frequently. Therefore, it becomes necessary to install empty pallets on those worktables that are no longer in use due to the reduction in steps, in order to continue supporting automated material handling processes. The main function of the empty pallet is to be precisely fixed to the equipment's worktable and to connect to the sheet metal bracket, thereby maintaining the smooth operation of the entire system. However, the empty pallets currently commonly used in the industry are quite heavy and cannot be handled manually, requiring overhead crane transport, resulting in longer die removal times and higher risks. Utility Model Content

The limiting member is provided with a limiting part, which has a locking position and a releasing position. The limiting part is capable of reciprocating between the locking position and the releasing position.

[0013] The limiting part is located at the release position, and the limiting part is separated from the groove wall of the slide, so that the first mounting bracket can move relative to the slide.

[0014] The limiting part is located in the locking position, and the limiting part abuts against the groove wall of the slide to restrict the movement of the first mounting bracket relative to the slide.

[0015] In one embodiment, the first limiting component further includes a handle connected to the rotating shaft, so that the handle can drive the limiting part to reciprocate between the locking position and the releasing position via the rotating shaft.

[0031] In addition, this utility model also proposes a plate empty platform, which includes a plate bracket, a worktable, and an empty bracket as described in any of the above technical solutions. The first support member and the second support member are detachably connected to the plate bracket. The plate bracket is used to abut against the plate. The number of empty brackets is at least two. The number of plate brackets is consistent with the number of empty brackets and is arranged in a one-to-one correspondence.

[0032] In this embodiment of the utility model, by statistically analyzing the requirements for fixing the empty pallet and installing the plate bracket, a new empty pallet is designed using a data-driven approach. The specific dimensions of the empty pallet can be selected based on the structural characteristics of the workbench, satisfying both installation on the workbench and fixing of the plate bracket. The frame is the basic framework of the entire empty pallet, supporting and connecting other functional modules. The frame is a segmented, detachable structure, including a first mounting frame, a second mounting frame, and a third mounting frame. The traditional one-piece welded empty pallet is improved into a modular structure, making it easier for manual handling and quick replacement. The first and second mounting frames respectively carry corresponding limiting components and support components, participating in overall guidance and limiting. Both the first and second mounting frames slide with the grooves on the workbench, forming a movable base. The third mounting frame serves as an intermediate load-bearing module, connecting the two side mounting frames and providing central support. Both the first and second mounting frames are detachably connected to the third mounting frame, thereby improving the overall assembly flexibility. The support mechanism provides stable support for the plate bracket and transfers loads. A first support member is mounted on a first mounting bracket, and a second support member is mounted on a second mounting bracket. Both are detachably connected to the plate bracket, forming a symmetrical or spaced support layout. This creates a stable two-point support structure on the unloaded plate table, preventing uneven loading or tilting of the plate bracket. The limiting mechanism prevents the unloaded bracket from accidentally sliding or shifting on the worktable, ensuring its positioning stability. The limiting mechanism includes a first limiting component and a second limiting component, which are rotatably mounted on the first and second support members, respectively. This double-sided limiting arrangement enhances the stability of the unloaded bracket on the slide, preventing shifting or accidental sliding and improving safety and reliability during operation. The positioning mechanism connects to the first and / or second support members and engages with the worktable, enabling rapid and accurate positioning of the unloaded bracket and the worktable. This improves positioning consistency and reliability during automated equipment handling and effectively enhances assembly accuracy.This utility model embodiment improves the traditional one-piece welded empty tray structure into a three-section detachable structure, fundamentally solving many defects of traditional welded empty trays. It significantly reduces the weight of the empty tray, allowing for manual installation and disassembly, completely eliminating the safety risks associated with overhead crane transport, and improving the safety of the working environment. Furthermore, since no overhead crane is needed for handling and positioning, the time for a single mold segment removal can be shortened by approximately 8 minutes, greatly improving production efficiency. This enhances equipment utilization and overall production rhythm, facilitating flexible and lean production management, enabling small-batch, multi-batch production, and thus adapting to various needs. Diverse order requirements; furthermore, the segmented and detachable design allows for replacement or maintenance of the unloaded bracket without the need for complete disassembly, requiring only operation of specific modules. This not only facilitates daily maintenance and replacement but also supports flexible adjustments to the structural configuration according to different working conditions, exhibiting excellent versatility and expandability, effectively reducing manufacturing costs. The unloaded bracket possesses good structural strength and sufficient toughness, meeting the load-bearing performance requirements of automated stamping equipment. Simultaneously, its structural design fully integrates with the actual layout and installation needs of the equipment, demonstrating strong adaptability and high installation stability. In terms of service life, its durability is comparable to existing unloaded pallets, fully meeting the practical needs of frequent mold changes and long-term use in industrial production.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0049] The stamping process typically involves four steps: drawing, trimming, flanging, and forming / punching. To ensure the machinability of all dies, the equipment is equipped with four worktables to accommodate these steps. With the increasing intensification and simplification of die design and advancements in processing technology, the production steps for some products have been reduced, potentially requiring only two or three steps. This means that dies on some worktables are used less frequently. Therefore, it becomes necessary to install empty pallets on those worktables that are no longer in use due to the reduction in steps, in order to continue supporting automated material handling processes. The main function of the empty pallet is to be precisely fixed to the equipment's worktable and to connect to the sheet metal bracket, thereby maintaining the smooth operation of the entire system. However, the empty pallets currently commonly used in the industry are quite heavy and cannot be handled manually, requiring overhead crane transport, resulting in longer die removal times and higher risks.

[0050] After careful research, the applicant discovered that the industry currently commonly uses welded integrated unloaded pallets. While this structure offers strong rigidity and flexibility, it also presents several significant problems. First, its weight is approximately 1 ton, and its dimensions are 3.9 meters × 1.6 meters, making it impossible to handle manually and requiring overhead crane transport. Second, each hoisting process adds approximately 8 minutes of time, which not only increases mold removal time but also impacts overall production efficiency. Furthermore, using overhead cranes for hoisting introduces the safety hazard of heavy objects falling, increasing operational risks.

[0051] The main purpose of this utility model is to propose an empty pallet and plate empty platform to solve the problem of how to shorten the mold segment removal time and improve safety.

[0052] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment of this utility model, the unloaded bracket 100 includes a frame 1, a support mechanism 2, a limiting mechanism 3, and a positioning mechanism 4. The frame 1 includes a first mounting bracket 11, a second mounting bracket 12, and a third mounting bracket 13. The first mounting bracket 11 and the second mounting bracket 12 are both detachably connected to the third mounting bracket 13. The first mounting bracket 11 and the second mounting bracket 12 are both slidably engaged with the slide groove 2201 of the workbench 220. The support mechanism 2 includes a first support member 21 and a second support member 22. The first support member 21 is disposed on the first mounting bracket 11, and the second support member 22 is disposed on the second mounting bracket 11. 2. Both the first support member 21 and the second support member 22 are used to connect with the plate bracket 210; the limiting mechanism 3 includes a first limiting component 31 and a second limiting component 32. The first limiting component 31 is rotatably mounted on the first support member 21, and the second limiting component 32 is rotatably mounted on the second support member 22. Both the first limiting component 31 and the second limiting component 32 can abut against the groove wall of the slide 2201 to limit the movement of the frame 1 relative to the slide 2201; the positioning mechanism 4 is connected to the first support member 21 and / or the second support member 22, and the positioning mechanism 4 can engage with the worktable 220.

[0053] In this embodiment of the utility model, by statistically analyzing the requirements for fixing the empty tray and installing the plate bracket 210, a new empty bracket 100 is designed using a data-driven approach. The specific dimensions of the empty bracket 100 can be selected in conjunction with the structural characteristics of the workbench 220, which satisfies both the installation on the workbench 220 and the fixing of the plate bracket 210. The frame 1 is the basic framework of the entire unloaded tray 100, which supports and connects other functional modules. The frame 1 is a segmented and detachable structure. The frame 1 includes a first mounting frame 11, a second mounting frame 12 and a third mounting frame 13. The traditional one-piece welded unloaded tray is improved into a modular structure, which is more convenient for manual handling and quick replacement. The first mounting frame 11 and the second mounting frame 12 respectively carry the corresponding limiting components and support components, and participate in the overall guidance and limiting. The first mounting frame 11 and the second mounting frame 12 are both slidably engaged with the slide groove 2201 on the workbench 220 to form a movable base. The third mounting frame 13 serves as an intermediate load-bearing module, connecting the two mounting frames and providing central support. The first mounting frame 11 and the second mounting frame 12 are both detachably connected to the third mounting frame 13, thereby improving the overall assembly flexibility. The support mechanism 2 provides stable support for the plate bracket 210 and transfers the load. The first support member 21 is disposed on the first mounting frame 11, and the second support member 22 is disposed on the second mounting frame 12. Both are detachably connected to the plate bracket 210, forming a symmetrical or spaced support layout. This creates a stable two-point support structure in the plate unloaded table 200, thereby preventing the plate bracket 210 from being unbalanced or tilted. The limiting mechanism 3 prevents the unloaded bracket 100 from accidentally sliding or deviating on the worktable 220, ensuring its positioning stability. The limiting mechanism 3 includes a first limiting component 31 and a second limiting component 32, which are rotatably mounted on the first support member 21 and the second support member 22, respectively. By adopting a double-sided limiting arrangement, the stability of the unloaded bracket 100 on the slide groove 2201 is enhanced, preventing deviation or accidental sliding and improving the safety and reliability during operation. The positioning mechanism 4 is connected to the first support member 21 and / or the second support member 22, and can engage with the workbench 220 to achieve rapid and accurate positioning of the unloaded bracket 100 and the workbench 220, thereby improving the positioning consistency and reliability in the automated handling process of the equipment and effectively improving the assembly accuracy.

[0054] The technical solution of this utility model improves the traditional one-piece welded empty tray 100 into a three-section detachable structure, fundamentally solving many defects of the traditional welded empty tray. This significantly reduces the weight of the empty tray 100, allowing it to be installed and disassembled entirely manually, completely eliminating the safety risks associated with overhead crane transport, and improving the safety of the working environment. Furthermore, since there is no need for overhead crane transport and positioning, the time for a single mold segment removal can be shortened by approximately 8 minutes, greatly improving production efficiency. This, in turn, enhances equipment utilization and overall production rhythm, facilitating flexible and lean production management, and enabling small-batch, multi-batch production. It adapts to diverse order demands; furthermore, the segmented and detachable design allows the unloaded bracket 100 to be replaced or maintained without the need for complete disassembly, requiring only operation on specific modules. This not only facilitates daily maintenance and replacement but also supports flexible adjustments to the structural configuration according to different working conditions, exhibiting excellent versatility and expandability, and effectively reducing manufacturing costs. The unloaded bracket 100 possesses good structural strength and sufficient toughness, meeting the load-bearing performance requirements of automated stamping equipment. Simultaneously, its structural design fully integrates with the actual layout and installation needs of the equipment, demonstrating strong adaptability and high installation stability. In terms of service life, its durability is comparable to existing unloaded pallets, fully meeting the practical needs of frequent mold changes and long-term use in industrial production.

[0055] Please see Figure 3In one embodiment, the first mounting bracket 11 includes a first bracket body 111, a first connector 112, and a first fastener (not shown). The first connector 112 is provided with a first receiving groove 1121 and a first mounting hole 1122. The first receiving groove 1121 is used to receive at least a portion of the structure of the third mounting bracket 13. The first mounting hole 1122 communicates with the first receiving groove 1121. The third mounting bracket 13 is provided with a second mounting hole 131. The first fastener passes through the first mounting hole 1122 and the second mounting hole 131 to restrict the movement of the third mounting bracket 13 relative to the first mounting bracket 11; and / or, the second mounting bracket 12 includes a second bracket body 121, a second connector 122, and a second fastener (not shown). The second connector 122 is provided with a second receiving groove 1221 and a third mounting hole 1222. The second receiving groove 1221 is used to receive at least a portion of the structure of the third mounting bracket 13. The third mounting hole 1122... The second mounting bracket 11 is connected to the second receiving groove 1221. The third mounting bracket 13 is provided with a fourth mounting hole 132. The second fastener passes through the third mounting hole 1222 and the fourth mounting hole 132 to restrict the movement of the third mounting bracket 13 relative to the second mounting bracket 12. Specifically, the first receiving groove 1121 and the second receiving groove 1221 can provide guidance and pre-positioning functions for the third mounting bracket 13, reduce assembly difficulty, avoid overall structural skew due to assembly errors, and improve on-site operation efficiency. The first fastener and the second fastener can achieve final locking. This combined structure not only ensures the convenience of assembly, but also meets the safety requirements during operation. Moreover, the first mounting bracket 11 and the second mounting bracket 12 are connected to the third mounting bracket 13 from both sides to form a symmetrical structure, which significantly improves the overall rigidity and enhances the torsional resistance. All connecting parts and fasteners are designed to be detachable, which facilitates the replacement of damaged parts or adjustment of the structural layout in the later stage and reduces downtime. In this embodiment, for ease of manufacturing and installation, the first connector 112 and the second connector 122 have identical structures and the same mounting hole dimensions, supporting standardized processing and interchangeability, thus reducing manufacturing costs and inventory pressure. In this embodiment, the first and second fasteners can be bolts and nuts or limit pins; this embodiment does not limit their use.

[0056] Please see Figure 2 and Figure 4In one embodiment, the first limiting assembly 31 includes a rotating shaft 311 and a limiting member 312 connected to each other. The rotating shaft 311 is rotatably mounted on the first mounting bracket 11. The limiting member 312 is provided with a limiting portion 3121, which has a locking position (not shown) and a releasing position (not shown). The limiting portion 3121 can reciprocate between the locking position and the releasing position. When the limiting portion 3121 is in the releasing position, the limiting portion 3121 and the slide groove 2201... The groove wall is separated so that the first mounting frame 11 can move relative to the slide 2201; the limiting part 3121 is in the locked position and abuts against the groove wall of the slide 2201 to restrict the movement of the first mounting frame 11 relative to the slide 2201; specifically, the rotating shaft 311 is rotatably mounted on the first mounting frame 11 so that the limiting part 3121 can freely switch between the locked position and the release position to meet the limiting requirements under different working conditions and improve the adaptability of the equipment. When locked, the limiting part 3121 is in close contact with the wall of the slide 2201, generating sufficient friction or locking force to prevent the unloaded bracket 100 from accidentally sliding or shifting during operation. This significantly improves the safety of the equipment during operation and the operator's confidence. The limiting part 3121 abuts against the wall of the slide 2201 through mechanical contact, which is simple in structure and has a stable limiting effect. It does not rely on an electronic control system and is suitable for various complex industrial environments. When released, the limiting part 3121 is completely disengaged from the wall of the slide 2201, reducing movement resistance and allowing the unloaded bracket 100 to slide smoothly in the slide 2201. This facilitates position adjustment or module replacement, shortens installation and commissioning time, and helps to improve the overall production cycle.

[0057] Please see Figure 2 and Figure 4 In one embodiment, the first limiting component 31 further includes a handle 313, which is connected to a rotating shaft 311 so that the handle 313 can drive the limiting part 3121 to reciprocate between the locked position and the released position via the rotating shaft 311. Specifically, the handle 313 changes the state switching of the limiting part 3121 from a mechanical operation to a manual operation that can be directly intervened, greatly improving the convenience and response speed of use. It does not rely on electric or pneumatic devices, and the limiting function can be switched by the handle 313 alone, simplifying the system structure, reducing failure points, and improving the stability of equipment operation. The handle 313 is rigidly connected to the rotating shaft 311 to ensure consistent action during operation and avoid the limiting part 3121 not being in place or malfunctioning due to transmission errors. Moreover, by driving the limiting part 3121 to switch states through the handle 313, the fast control of whether the unloaded bracket 100 is fixed can be realized. The operation is intuitive and the action is clear, making it suitable for environments with frequent mold changing operations.

[0058] Please see Figures 1 to 3In one embodiment, the positioning mechanism 4 includes a first positioning component 41 and a second positioning component 42. The first positioning component 41 is connected to the first mounting bracket 11, and the second positioning component 42 is connected to the second mounting bracket 12. The first positioning component 41 and the second positioning component 42 are arranged at intervals along a first direction. The first positioning component 41 and the second positioning component 42 can respectively engage with the first positioning groove 2202 and the second positioning groove 2203 on the worktable 220. Specifically, as shown... Figure 1 As shown, the first direction is the left-right direction. Two positioning components are arranged at intervals along the first direction, and each positioning component cooperates with two positioning slots to form a two-point positioning structure. This effectively prevents the unloaded bracket 100 from shifting or tilting during installation, reduces the alignment time during mold segment removal, and helps improve the overall operating efficiency of the stamping line. Furthermore, the precise mechanical positioning structure provides a good foundation for the subsequent introduction of robotic automatic handling and assembly in the production line, which is conducive to the automation upgrade of the production line. Without relying on a complex control system, the unloaded bracket 100 can be quickly aligned and locked into the designated position on the workbench 220 simply through mechanical snap-fit. This reduces manual debugging time, improves equipment online efficiency, and avoids positioning failure due to electrical faults, ensuring operational safety.

[0059] According to one embodiment of the present invention, the positioning mechanism 4 includes a first positioning component 41, which is connected to the first mounting bracket 11. The first positioning component 41 can engage with the first positioning groove 2202 on the workbench 220. By setting the first positioning component 41, the unloaded bracket 100 is prevented from shifting or tilting during installation.

[0060] According to another embodiment of the present invention, the positioning mechanism 4 includes a second positioning component 42, which is connected to the second mounting bracket 12. The second positioning component 42 is engaged with the second positioning groove 2203 on the workbench 220. By setting the second positioning component 42, the unloaded bracket 100 is prevented from shifting or tilting during installation.

[0061] Please see Figures 1 to 3 In one embodiment, the positioning mechanism 4 further includes a third positioning component 43, which is connected to the third mounting bracket 13. The third positioning component 43 can engage with the boss 2204 on the worktable 220 to restrict the third mounting bracket 13 from moving relative to the worktable 220 in a second direction. The first direction is perpendicular to the second direction. Specifically, as shown in the figure... Figure 1As shown, the second direction is the front-to-back direction. The third positioning component 43 cooperates with the boss 2204 on the worktable 220, enabling the third mounting bracket 13 to achieve precise positioning in the second direction as well, compensating for the shortcomings of unidirectional positioning. By setting the first positioning component 41, the second positioning component 42, and the third positioning component 43, positioning in both the first and second directions is achieved, forming a three-dimensional positioning system. This significantly improves the connection rigidity and anti-deflection capability between the unloaded bracket 100 and the worktable 220, effectively preventing the unloaded bracket 100 from sliding or misaligning during handling, ensuring operational safety. Furthermore, the third positioning component 43 and the boss 2204 use a snap-fit ​​connection, allowing for rapid positioning of the third mounting bracket 13 without additional tools, reducing alignment time during mold segment removal, and contributing to improved overall operating efficiency of the stamping line.

[0062] Please see Figure 1 In one embodiment, the first positioning component 41 includes a first connecting rod 411 and a first positioning element 412. The first connecting rod 411 is connected to the first mounting bracket 11, and the first positioning element 412 is connected to the first connecting rod 411. The first positioning element 412 can engage with the first positioning groove 2202. And / or, the second positioning component 42 includes a second connecting rod 421 and a second positioning element 422. The second connecting rod 421 is connected to the second mounting bracket 12, and the second positioning element 422 is connected to the second connecting rod 421. The second positioning element 422 can engage with the second positioning groove 2203. And / or, the third positioning component 43... A slot 431 is provided, which engages with the boss 2204. Specifically, considering the structural characteristics of the workbench 220, in this embodiment, the first positioning component 412 and the second positioning component 422 engage with the two positioning slots respectively, providing a limit in the first direction. The third positioning component 43 engages with the boss 2204 through the slot 431, providing a limit in the second direction. This multi-point synergy significantly improves the overall positioning accuracy and repeatability. Furthermore, both the first positioning component 41 and the second positioning component 42 are composed of connecting rods and positioning components, resulting in a simple structure and high degree of standardization, which is beneficial for subsequent assembly and debugging, and improves production efficiency. In this embodiment, the specific structure of the three positioning components can be flexibly adjusted according to different workbench 220 configurations, thereby adapting to various machine models and production line requirements and expanding the product's applicability.

[0063] Please see Figures 1 to 3In one embodiment, the support mechanism 2 further includes a third support member 23, which is disposed on the third mounting frame 13 and is used to connect with the plate bracket 210. Specifically, each unloaded bracket 100 is provided with three support members, which are respectively disposed on three different mounting frames. Therefore, on the unloaded plate platform 200, when two unloaded brackets 100 are symmetrically arranged on both sides of the plate bracket 210, each unloaded bracket 100 can provide three points of support, forming a six-point positioning structure. The six-point positioning can effectively prevent any type of plate bracket 210 from tilting, shifting, or experiencing uneven local stress during handling or processing, significantly improving the applicability and safety of the unloaded bracket 100.

[0064] Please see Figure 1 and Figure 3 In one embodiment, the first support member 21 is provided with a first groove 211 that accommodates at least a portion of the structure of the plate bracket 210; and / or, the second support member 22 is provided with a second groove 221 that accommodates at least a portion of the structure of the plate bracket 210; and / or, the third support member 23 is provided with a third groove 231 that accommodates at least a portion of the structure of the plate bracket 210; and / or, the unloaded bracket 100 is made of plastic. Specifically, the design of the first groove 211, the second groove 221, and the third groove 231 effectively increases the contact area and limiting ability between the support member and the plate bracket 210, significantly improving the stability during the load-bearing process. Furthermore, the grooves have guiding and limiting functions, enabling the plate bracket 210 to be quickly positioned and stably placed during installation, improving on-site operational efficiency. In this embodiment, the grooves can be adjusted according to different models of plate brackets 210, thereby improving the versatility and adaptability of the unloaded bracket 100. The unloaded bracket 100 is made of plastic. Compared with the traditional metal structure, the plastic material significantly reduces the weight of the unloaded bracket 100. Each bracket is lightweight, weighing only 4 kg, making it easy for operators to carry out handling work and reducing reliance on heavy equipment such as overhead cranes.

[0065] In this embodiment, all components of the empty tray 100 can be 3D printed and then assembled and debugged. 3D printing technology can use materials precisely, ensuring accuracy requirements while reducing unnecessary weight, thus helping to further reduce the overall weight of the empty tray 100. Furthermore, the price of a traditional welded empty tray is approximately 50,000 yuan per unit, while this invention, using 3D printing technology, has a manufacturing cost of approximately 1,500 yuan per unit, a cost reduction of 48,500 yuan per unit. Each empty tray 100 is compact and easy to store, saving approximately 6 square meters of storage space compared to traditional large trays, resulting in cost savings of approximately 60,000 yuan. In total, each empty tray 100 can save 108,500 yuan, which translates to a saving of 21,700 yuan over 5 years. This significantly reduces long-term operating costs, facilitating flexible and lean production management, enabling small-batch, multi-batch production to meet diverse order demands.

[0066] According to one embodiment of the present invention, the unloaded bracket 100 can be injection molded, which has high processing efficiency, low cost, and is conducive to large-scale application and promotion.

[0067] In this embodiment, for ease of manufacturing and installation, the first mounting bracket 11 and the second mounting bracket 12 have the same structure, the first support member 21, the second support member 22 and the third support member 23 have the same structure, the first limiting component 31 and the second limiting component 32 have the same structure, and the first positioning component 41 and the second positioning component 42 have the same structure.

[0068] Please see Figures 5 to 8This utility model also proposes a plate empty platform 200, which includes a plate bracket 210, a worktable 220, and an empty bracket 100. The specific structure of the empty bracket 100 is as described in the above embodiments. Since this plate empty platform 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the first support member 21 and the second support member 22 are detachably connected to the plate bracket 210. The plate bracket 210 is used to abut against the plate 300. The number of empty brackets 100 is at least two, and the number of plate brackets 210 is consistent with the number of empty brackets 100 and is set one-to-one. Specifically, the limiting mechanism 3 on the empty bracket 100 cooperates with the sliding groove 2201 on the worktable 220 to realize the switching of the fixed state. The positioning mechanism 4 on the empty bracket 100 cooperates with the two positioning mechanisms on the worktable 220. The slot and boss 2204 engage to ensure installation accuracy. Both support members are detachably connected to the plate bracket 210, facilitating flexible replacement of the plate bracket 210 according to different plate 300 requirements. At least two unloaded brackets 100 form a multi-point support structure to ensure even force distribution on the plate bracket 210, preventing tilting or deformation due to uneven local force distribution, thus improving the stability and safety of the equipment during operation. The entire system supports fully automated robotic arm handling of plate 300, improving production efficiency and consistency. In this embodiment, the number of unloaded brackets 100 and plate brackets 210 can be flexibly configured according to different plate 300 sizes or mold process requirements. Both the first support member 21 and the second support member 22 can be detachably connected to the plate bracket 210 by screwing or snapping, but this embodiment does not limit this.
