Description

A rotating fixture for plate-shaped products Technical Field

[0001] This application relates to the field of plate-shaped product transfer processing technology, and in particular to a plate-shaped product transfer fixture. Background Technology

[0002] In the industrial production of many industries such as electronic components, optical components, new energy plates, thin metal sheets, and smart wearable display panels, a large number of plate-shaped and sheet-shaped workpieces need to go through multiple processing steps to complete the entire production process. Between each process, multiple plate-shaped objects arranged in rows need to be removed from the support fixture of the current process and transferred synchronously to the target fixture of the next process. In order to reduce the time spent on loading and unloading in a single process and improve the overall production efficiency, the industry generally adopts multi-station synchronous clamping fixtures to realize the one-time synchronous transfer of multiple rows and multiple quantities of plate-shaped objects, thereby adapting to the needs of large-scale and continuous mass production operations.

[0003] In related technologies, the multi-plate object synchronous transfer fixture widely used in the industry mainly adopts a structure scheme of multiple clamping units linked by elastic elements. It includes a base, multiple clamping units arranged at intervals along a preset direction, a drive rod that can slide along the base, clamping elastic elements, and reset elastic elements. Each clamping unit includes two clamping parts that slide with the base, and a connecting part that is pivotally connected to the base in the middle. The two ends of the connecting part are respectively connected to the two clamping parts in the same group. The drive rod is provided with a pushing part corresponding to each connecting part.

[0004] Under normal initial conditions without external force, the elastic force of the clamping elastic element continuously acts on each linkage, causing all linkages to rotate synchronously in the same direction. Through the transmission cooperation between the linkages and the clamping elements, the two clamping elements of each clamping unit are synchronously driven to slide towards each other, so that all clamping units synchronously maintain stable clamping of the plate-shaped object. The clamping force is continuously provided by the clamping elastic element. When it is necessary to release the object, a continuous external force is applied to the drive rod, causing the drive rod to slide along the base. The drive rod pushes all linkages synchronously through its pushing part, causing the linkages to overcome the elastic force of the clamping elastic element and rotate in the opposite direction. This, in turn, synchronously drives the two clamping elements of each clamping unit to slide in opposite directions, achieving synchronous release of all clamping units. When the external force applied to the drive rod is removed, the reset elastic element releases its elastic force, causing the drive rod to slide in the opposite direction and reset. At the same time, the clamping elastic element synchronously drives all linkages to rotate back and reset, thereby driving the clamping elements of each clamping unit to slide towards each other, so that all clamping units synchronously reset to the clamping state.

[0005] However, the clamping force of the above-mentioned technical solution depends on the elastic force of the clamping elastic element. With the increase of the number of uses, the elastic force of the clamping elastic element is prone to decay, resulting in a decrease in clamping force. After long-term use, the workpiece may not be clamped firmly and may fall off during the transfer process. Summary of the Invention

[0006] To address the aforementioned problems, this application provides a rotating fixture for plate-shaped products.

[0007] This application provides a rotating fixture for plate-shaped products, employing the following technical solution: It includes a rotating fixture body, which comprises a support, a clamping mechanism, and a pneumatic drive mechanism. The clamping mechanism includes a first clamping member and a second clamping member, both of which slide in cooperation with the support. The pneumatic drive mechanism is fixedly mounted on the support and includes a pneumatic drive component and a pneumatic control component. The pneumatic drive component and the pneumatic control component are connected by air circuits, and the pneumatic control component controls the power of the pneumatic drive component. The pneumatic drive unit's power output end is connected to the clamping mechanism. The pneumatic drive unit drives the two clamping members to slide in opposite straight lines along the bracket. When the power output end of the pneumatic drive unit moves, it drives the first clamping member and the second clamping member to slide in opposite straight lines along the bracket, thereby aligning the plate-shaped product, releasing the clamping limit on the plate-shaped product, and releasing the plate-shaped product. After the power output end of the pneumatic drive unit is reset, it provides a continuous and constant clamping force to the first clamping member and the second clamping member to achieve stable clamping of the plate-shaped product.

[0008] By adopting the above technical solution, the pneumatic drive component and the pneumatic control component are connected in an air circuit. The pneumatic control component controls the power output state of the pneumatic drive component. The power output end of the pneumatic drive component is connected to the clamping mechanism. When the power output end of the pneumatic drive component moves, it drives the first and second clamping components to make opposite linear sliding movements, thereby aligning the plate-shaped product, releasing the clamping limit on the plate-shaped product, and releasing the plate-shaped product. When the power output end of the pneumatic drive component is stationary, the pneumatic control component does not need to output air to the pneumatic drive component. The power output end resets, causing the transmission rod to rotate in the opposite direction and reset, which in turn drives the first and second clamping parts to make opposite linear sliding movements, thus achieving stable clamping of the plate-shaped product. The clamping force is provided by the constant force of the pneumatic drive in the reset state. The clamping force will not decrease with the increase of the number of times the rotating fixture body is used. It does not require the pneumatic control component to continuously output air to the pneumatic drive, reducing the interference of the pneumatic drive mechanism components on the clamping action, and ensuring that the first and second clamping parts maintain a stable clamping state on the plate-shaped product throughout the entire process of multi-process transfer of the plate-shaped product.

[0009] Preferably, the clamping mechanism further includes a transmission rod, the two ends of which are respectively connected to the first clamping member and the second clamping member, the middle part of which is rotatably connected to the bracket, and the power output end of the pneumatic drive member is connected to either end of the transmission rod.

[0010] By adopting the above technical solution, the power output end of the pneumatic drive component is connected to either end of the transmission rod, and the middle part of the transmission rod is rotatably connected to the bracket to form a fixed rotation fulcrum. Since the two ends of the transmission rod are respectively connected to the first clamping component and the second clamping component, the connection points between the first clamping component and the transmission rod and the connection points between the second clamping component and the transmission rod are located on both sides of the rotation fulcrum. Both the first clamping component and the second clamping component slide with the bracket. When the transmission rod rotates around the rotation fulcrum, the two ends of the transmission rod will generate displacement in the opposite direction along the sliding direction of the bracket. This displacement is synchronously transmitted to the first clamping component and the second clamping component, causing the first clamping component and the second clamping component to make linear sliding movements in opposite directions along the sliding path of the bracket, thereby realizing the clamping and releasing action of the plate-shaped item.

[0011] Preferably, the first clamping member includes a plurality of first clamping pieces fixedly arranged at equal intervals along its own length direction, and the second clamping member includes a plurality of second clamping pieces fixedly arranged at equal intervals along its own length direction. After the power output end of the pneumatic drive is reset, each of the first clamping pieces of the first clamping member is located one-to-one in the gap between two adjacent second clamping pieces of the second clamping member.

[0012] By adopting the above technical solution, the first clamping member includes multiple first clamping plates that are fixedly arranged at equal intervals along the length direction of the first clamping member, and the second clamping member includes multiple second clamping plates that are fixedly arranged at equal intervals along the length direction of the second clamping member. When the power output end of the pneumatic drive is stationary, each of the first clamping plates of the first clamping member is located in the gap between two adjacent second clamping plates of the second clamping member. The equal-interval first clamping plates and the equal-interval second clamping plates form multiple sets of clamping stations with the same specifications, so that the main body of the rotating jig can simultaneously complete the synchronous clamping and transfer of multiple plate-shaped products. The equal-interval arrangement, combined with the transmission rod driving the first clamping member and the second clamping member to slide in opposite directions, ensures that the opening and closing stroke and clamping force of all clamping stations remain completely consistent, so that each plate-shaped product can obtain a uniform and stable clamping effect, and improve the working efficiency and clamping consistency of the main body of the rotating jig.

[0013] Preferably, the power output end of the pneumatic drive unit rotates the transmission rod, driving the first clamping member to slide closer to the pneumatic drive unit and the second clamping member to slide away from the pneumatic drive unit, until all the first clamping pieces abut against and are limited by the adjacent second clamping pieces on the side closer to the pneumatic drive unit. When the power output end of the pneumatic drive unit resets, the reset of the power output end of the pneumatic drive unit drives the transmission rod to rotate in the opposite direction to reset, driving the first clamping member to slide away from the pneumatic drive unit and the second clamping member to slide closer to the pneumatic drive unit.

[0014] By adopting the above technical solution, when the power output end of the pneumatic drive is stationary, each of the first clamping plates of the first clamping member is positioned one-to-one in the gap between two adjacent second clamping plates of the second clamping member. The movement of the power output end of the pneumatic drive causes the transmission rod to rotate, and the transmission rod synchronously drives the first clamping member to slide closer to the pneumatic drive and the second clamping member to slide away from the pneumatic drive until all the first clamping plates abut and are limited to contact with the adjacent second clamping plates on the side closer to the pneumatic drive. During the sliding process, the distance between the first clamping plates and the adjacent second clamping plates on the side away from the pneumatic drive gradually increases, forming multiple sets of uniformly sized accommodating spaces suitable for placing plate-shaped items. When the plate-shaped item is located in the receiving space, when the power output end of the pneumatic drive component is reset to a stationary state, the power output end of the pneumatic drive component drives the transmission rod to rotate in the opposite direction and reset. The transmission rod synchronously drives the first clamping component to slide away from the pneumatic drive component and drives the second clamping component to slide closer to the pneumatic drive component. The first clamping piece of the first clamping component and the second clamping piece of the second clamping component slide synchronously with the corresponding clamping component. The distance between the first clamping piece and the adjacent second clamping piece on the side away from the pneumatic drive component gradually decreases until the first clamping piece and the second clamping piece on the side away from the pneumatic drive component clamp and abut against the side wall of the plate-shaped item, forming a stable clamping of the plate-shaped item placed in the receiving space.

[0015] Preferably, the end of the first clamping piece away from the first clamping member and the end of the second clamping piece away from the second clamping member are both rounded and blunted.

[0016] By adopting the above technical solution, the end of the first clamping piece away from the first clamping member and the end of the second clamping piece away from the second clamping member are both rounded and blunted, so that the end of the first clamping piece and the second clamping piece form a continuous and smooth transition structure. During the placement, removal and sliding clamping of plate-shaped items, when the first clamping piece and the second clamping piece and the plate-shaped item accidentally come into contact and collide, the continuous and smooth transition structure of the first clamping piece and the second clamping piece can disperse the force generated by the contact and reduce the probability of damage to the plate-shaped item after being affected by the contact.

[0017] Preferably, the bracket is provided with a support plate, and the first clamping member and the second clamping member are slidably disposed on the two side surfaces of the support plate. The first clamping member is provided with a first protrusion on the side edge away from the first clamping piece, and the second clamping member is provided with a second protrusion on the side edge away from the second clamping piece. Both the first protrusion and the second protrusion abut against the upper surface of the support plate.

[0018] By adopting the above technical solution, the first and second clamping members are slidably disposed on both sides of the support plate. The first and second protrusions abut against the upper surface of the support plate. The support plate provides load-bearing support for the reciprocating sliding of the first and second clamping members. The abutment between the first and second protrusions and the upper surface of the support plate constrains the positional offset of the first and second clamping members along the direction perpendicular to the support plate during the sliding process, maintaining the height alignment consistency of the first clamping piece on the first clamping member and the second clamping piece on the second clamping member. The abutment cooperation between the first and second protrusions and the support plate can disperse the force generated during the sliding process of the first and second clamping members, and improve the stability of the reciprocating sliding operation of the first and second clamping members.

[0019] Preferably, two sets of guide posts are fixedly provided on the bearing plate, and each set of guide posts is provided with a plurality of them. The first clamping member and the second clamping member are provided with sliding grooves at the positions corresponding to the guide posts, and the guide posts are respectively inserted into the sliding grooves.

[0020] By adopting the above technical solution, two sets of guide posts are fixedly installed on the bracket, with several guide posts in each set. Sliding grooves are opened at the positions of the guide posts corresponding to the first and second clamping members. The guide posts are inserted into the sliding grooves. The guide posts provide a unified guiding reference for the sliding movement of the first and second clamping members. The insertion and cooperation relationship between the guide posts and the sliding grooves constrains the radial movement and angular deviation of the first and second clamping members during the sliding process, so that the first and second clamping members always slide in a straight line along the extension direction of the guide posts, ensuring that the sliding paths of the first and second clamping members remain parallel throughout, ensuring that the sliding strokes of the first and second clamping members are synchronized, and ensuring the alignment accuracy of the first clamping piece on the first clamping member and the second clamping piece on the second clamping member.

[0021] Preferably, the air pressure control component is a manual air pressure control component, and handles are fixedly provided on both sides of the bracket, with the air pressure control component located on one of the handles near one end of the bracket.

[0022] By adopting the above technical solution, the pneumatic control component is set as a manual pneumatic control component, which is adapted to the manual operation mode of the main body of the rotating jig. Handles are fixedly installed on both sides of the support, providing multiple gripping points for the overall transfer of the main body of the rotating jig, adapting to the gripping operation needs of operators in different work positions and different placement directions. The pneumatic control component is set on the handle near one end of the support, so that the operation point of the pneumatic control component is integrated with the gripping point of the handle. When the operator holds the handle to transfer the main body of the rotating jig or to load and unload materials, he can directly operate the pneumatic control component to switch the clamping state and release state of the main body of the rotating jig.

[0023] Preferably, the air pressure control component and the handle are detachably fixed to the bracket, and the mounting angle of the handle relative to the bracket is adjustable and lockable.

[0024] By adopting the above technical solution, the pneumatic control component and handle are detachably fixed to the bracket, which facilitates the individual disassembly and replacement of the pneumatic control component and handle when wear and tear occurs, reducing the maintenance cost of the main body of the rotating fixture. The installation angle of the handle relative to the bracket is adjustable and can be locked. The handle can also be adjusted to a suitable installation angle according to the operator's operating habits and grip posture. After adjustment, it is locked and fixed. When adjusting the installation angle of the handle, the pneumatic control component adjusts its position synchronously with the handle, so that the operating point of the pneumatic control component is always adapted to the operator's grip posture, adapting to the operating needs of different operators.

[0025] Preferably, the bracket is configured as a hollow structure.

[0026] By adopting the above technical solution, the support is designed with a hollow structure, which can reduce the amount of material used in the support as a whole, reduce the overall weight of the support itself, reduce the overall load on the main body of the rotating jig, adapt to the operation mode of the operator holding and transferring the main body of the rotating jig, and reduce the physical exertion of the operator when holding and transferring the main body of the rotating jig.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The clamping force is provided by a constant force in the reset state of the pneumatic drive component. The clamping force will not decrease with the increase of the number of times the main body of the rotating fixture is used. It does not require the pneumatic control component to continuously output air to the pneumatic drive component, reducing the interference of the pneumatic drive mechanism components on the clamping action, and ensuring that the first clamping component and the second clamping component maintain a stable clamping state on the plate-shaped product throughout the entire process of multi-process transfer of the plate-shaped product; 2. Through the equal-spaced arrangement of the first clamping component... The first clamping piece and the second clamping piece, which are arranged at equal intervals, form multiple sets of clamping stations with the same specifications. This allows the main body of the rotating fixture to simultaneously complete the synchronous clamping and transfer of multiple plate-shaped products. In conjunction with the abutment and limiting structure between the bearing plate and the first and second bosses, as well as the through-guide structure of the guide post and the sliding groove, the positional deviation of the first and second clamping pieces during the sliding process is constrained. This ensures that the opening and closing stroke and clamping force of all clamping stations remain completely consistent, and maintains the alignment accuracy of the first and second clamping pieces.

[0035] The present application will be further described in detail below with reference to Figures 1-6.

[0036] This application discloses a rotating jig for plate-shaped products. This application is mainly applied to circular glass covers for smart wearable products. These circular glass covers require multiple processes during production, including cleaning and strengthening. When transferring between these processes, the circular glass covers need to be transferred into a specially designed support frame. This application is adapted to the multi-process turnover operation of circular glass covers for smart wearable products, enabling the simultaneous clamping, transfer, and loading / unloading of multiple circular glass covers. Referring to Figure 1, the jig includes a main body 1, which comprises a support 2, a clamping mechanism 3, and a pneumatic drive mechanism 4.

[0037] Referring to Figure 2, specifically, the bracket 2 provides the bearing and installation foundation for the entire rotating jig body 1. It adopts a frame structure and the bracket 2 is set as a hollow structure 6. While ensuring the structural bearing strength, the material usage of the bracket 2 is reduced, the overall weight of the rotating jig body 1 is reduced, and it is suitable for manual hand-held transfer operations. The bracket 2 is provided with a bearing plate 21, which is arranged horizontally along the length of the bracket 2 to provide a bearing reference for the installation and sliding of the clamping mechanism 3.

[0038] Referring to Figures 3 and 4, the clamping mechanism 3 further includes a first clamping member 31, a second clamping member 32, and a transmission rod 33. Both the first clamping member 31 and the second clamping member 32 are slidably engaged with the bracket 2. Specifically, the first clamping member 31 and the second clamping member 32 are plate-shaped structures, slidably disposed on both sides of the bearing plate 21. The first clamping member 31 is provided with multiple first clamping pieces 311 arranged at equal intervals along its own length direction. The second clamping member 32 is provided with multiple second clamping pieces 321 arranged at equal intervals along its own length direction. A first clamping piece 321 is provided on the edge of the first clamping member 31 away from the first clamping pieces 311. The first boss 312 and the second boss 322 are provided on the side edge of the second clamping member 32 away from the second clamping piece 321. Both the first boss 312 and the second boss 322 abut against the upper surface of the support plate 21. Through the abutment and cooperation between the first boss 312 and the second boss 322 and the support plate 21, the positional displacement of the first clamping member 31 and the second clamping member 32 in the direction perpendicular to the support plate 21 during the sliding process is constrained. At the same time, the force generated by the sliding process of the first clamping member 31 and the second clamping member 32 is dispersed, the stability of the reciprocating sliding operation of the first clamping member 31 and the second clamping member 32 is improved, and the height alignment consistency of the first clamping piece 311 and the second clamping piece 321 is maintained.

[0039] Furthermore, two sets of parallel guide posts 211 are fixedly installed on the bracket 2. Each set of guide posts 211 has several posts. In this embodiment, the guide posts 211 are configured as guide bolts. Each set of guide posts 211 has four posts. All four guide posts 211 are vertically fixed on the bearing plate 21. The first clamping member 31 and the second clamping member 32 are provided with four sliding grooves 5 at the positions corresponding to the guide posts 211. The guide posts 211 are inserted into the sliding grooves 5. Each pair of guide posts 211 are parallel to each other. The insertion and cooperation relationship between the guide posts 211 and the sliding grooves 5 constrains the radial movement and angular deviation of the first clamping member 31 and the second clamping member 32 during the sliding process. This ensures that the first clamping member 31 and the second clamping member 32 always slide in a straight line through the guide posts 211, ensuring that the sliding paths of the first clamping member 31 and the second clamping member 32 remain parallel throughout the entire process and that the sliding strokes are synchronized. This ensures the alignment accuracy of the first clamping piece 311 and the second clamping piece 321.

[0040] Referring to Figure 4, the two ends of the transmission rod 33 are respectively connected to the first clamping member 31 and the second clamping member 32. The transmission rod 33 is hinged to the first clamping member 31 and the second clamping member 32. The middle part of the transmission rod 33 is rotatably connected to the bracket 2 through a rotating shaft, forming a fixed rotation fulcrum. The connection points of the first clamping member 31 and the transmission rod 33, and the connection points of the second clamping member 32 and the transmission rod 33, are located on both sides of the rotation fulcrum. When the transmission rod 33 rotates around the rotation fulcrum, the two ends of the transmission rod 33 will generate displacements in opposite directions along the extension directions of the two parallel guide posts 211. These displacements are synchronously transmitted to the first clamping member 31 and the second clamping member 32, causing the first clamping member 31 and the second clamping member 32 to slide in opposite directions along the sliding path of the bracket 2.

[0041] Referring to Figure 5, furthermore, the end of the first clamping piece 311 away from the first clamping member 31 and the end of the second clamping piece 321 away from the second clamping member 32 are both rounded and blunted, so that the end of the first clamping piece 311 away from the first clamping member 31 and the end of the second clamping piece 321 away from the second clamping member 32 are both semi-circular structures. During the placement, retrieval, and sliding clamping of the plate-shaped item, when the first clamping piece 311 and the second clamping piece 321 and the plate-shaped item accidentally come into contact or collide, the semi-circular structure can disperse the force generated by the contact and reduce the probability of damage to the plate-shaped item after being affected by the contact.

[0042] Referring to Figures 4 and 5, when the main body 1 of the rotating jig is in a stable clamping state, each of the first clamping pieces 311 of the first clamping member 31 is located one-to-one in the gap between two adjacent second clamping pieces 321 of the second clamping member 32. This indicates that, along the above arrangement direction, starting from the end of the bearing plate 21 near the pneumatic drive member 41, the clamping pieces located in odd-numbered positions are the second clamping pieces 321 of the second clamping member 32, and the clamping pieces located in even-numbered positions are the first clamping pieces 321 of the first clamping member 32. A clamping plate 311, and the first clamping plate 311 and the second clamping plate 321 arranged at equal intervals form multiple sets of clamping stations with the same specifications. Each set of clamping stations is adapted to the clamping requirements of a single round glass cover plate, so that the main body of the rotating jig 1 can simultaneously complete the synchronous clamping and transfer of multiple round glass cover plates. With the reverse synchronous sliding action driven by the transmission rod 33, it can be ensured that the opening and closing stroke and clamping force of all clamping stations remain completely consistent, so that each round glass cover plate can obtain a uniform and stable clamping effect.

[0043] Furthermore, the pneumatic drive mechanism 4 is fixedly mounted on the bracket 2. The pneumatic drive mechanism 4 includes a pneumatic drive component 41 and a pneumatic control component 42. In this embodiment, the pneumatic drive component 41 is mounted on the end of the bearing plate 21 away from the guide post 211. The pneumatic drive component 41 is configured as a cylinder, and the pneumatic control component 42 is configured as a valve. The pneumatic drive component 41 and the pneumatic control component 42 are connected by air circuits. The pneumatic control component 42 is used to control the power output of the pneumatic drive component 41. The power output end of the pneumatic drive component 41 is connected to the clamping mechanism 3 via a transmission.

[0044] Referring to Figure 4, specifically, the power output end of the pneumatic drive component 41 is fixedly connected to any one end of the transmission rod 33. In this embodiment, the power output end of the pneumatic drive component 41 is fixedly connected to the end of the transmission rod 33 away from the first clamping piece 311 and the second clamping piece 321. The transmission rod 33 is used to drive the two clamping pieces to slide in opposite straight lines along the bracket 2. Since the pneumatic drive component 41 is set as a cylinder, the power output end of the pneumatic drive component 41 is the piston rod of the cylinder. The end of the piston rod of the cylinder is fixedly provided with a transmission block 411. The transmission block 411 is fixedly provided with a connecting rod 4111. The connecting rod 4111 is hinged to one end of the transmission rod 33, thereby realizing the transmission connection between the power output end of the pneumatic drive component 41 and the transmission rod 33. Through this transmission connection structure, the pneumatic drive component 41 drives the transmission rod 33 to rotate around its own rotation fulcrum and the bracket 2, thereby driving the first clamping piece 31 and the second clamping piece 32 to slide in opposite straight lines along the bracket 2.

[0045] Referring to Figure 4, a limiting plate 22 is further fixedly installed on the bracket 2. The limiting plate 22 is located on the piston rod stroke path between the transmission rod 33 and the transmission block 411. When the piston rod of the cylinder extends to the preset stroke, the end face of the transmission block 411 and the limiting plate 22 abut against each other to limit the piston rod of the cylinder to continue to extend, thereby limiting the maximum opening and closing stroke of the first clamping member 31 and the second clamping member 32.

[0046] At the same time, when the power output end of the pneumatic drive 41 moves, it drives the first clamping member 31 and the second clamping member 32 to slide in opposite straight lines along the bracket 2 to release the circular glass cover. When the power output end of the pneumatic drive 41 is stationary, it provides a continuous and constant clamping force to the first clamping member 31 and the second clamping member 32 to achieve stable clamping of the circular glass cover. The specific operation process is as follows: the power output end of the pneumatic drive component 41 moves to represent the piston rod of the cylinder extending, which drives the transmission rod 33 to rotate through the transmission block 411 and the connecting rod 4111, driving the first clamping component 31 to slide towards the pneumatic drive component 41, and the second clamping component 32 to slide away from the pneumatic drive component 41, until all the first clamping pieces 311 abut against and limit the adjacent second clamping pieces 321 on the side closer to the pneumatic drive component 41. During this process, the distance between the first clamping pieces 311 and the adjacent second clamping pieces 321 on the side away from the pneumatic drive component 41 gradually increases, forming multiple sets of uniformly sized accommodating spaces, suitable for the batch placement of circular glass covers.

[0047] Furthermore, when the power output end of the pneumatic drive component 41 is stationary, the reset of the power output end of the pneumatic drive component 41 drives the transmission rod 33 to rotate in the opposite direction and reset, driving the first clamping component 31 to slide away from the pneumatic drive component 41, and the second clamping component 32 to slide towards the pneumatic drive component 41. The distance between the first clamping piece 311 and the corresponding adjacent second clamping piece 321 gradually decreases, forming a stable clamping on the circular glass cover plate placed in the accommodating space. The clamping force is provided by the constant force of the pneumatic drive component 41 in the reset state. The clamping force will not decrease with the increase of the number of times the rotating fixture body 1 is used, and the pneumatic control component 42 does not need to continuously output air source to the pneumatic drive component 41, reducing the interference of the pneumatic drive mechanism 4 components on the clamping action, and ensuring that the first clamping component 31 and the second clamping component 32 maintain a stable clamping state on the glass cover plate throughout the entire process of transferring the circular glass cover plate through multiple processes such as cleaning and strengthening.

[0048] Referring to Figure 3, further in this embodiment, the pneumatic control component 42 is a manually pressable air valve. The pneumatic control component 42 is equipped with a reciprocating press lever 421. An external air supply device is connected to the pneumatic control component 42, with the air inlet end connected to the external air supply device and the air outlet end connected to the pneumatic drive component 41 via an air passage. When the press lever 421 is pressed down, the internal air passage of the pneumatic control component 42 is opened, and the external air source inputs pressurized gas to the pneumatic drive component 41 through the pneumatic control component 42, driving the power output end of the pneumatic drive component 41 to extend, thereby... The drive rod 33 rotates, driving the first clamping member 31 and the second clamping member 32 to slide in the opposite direction along the bracket 2 to open, forming a space suitable for placing round glass covers, realizing batch placement of multiple round glass covers. When the pressing rod 421 is released, the internal air passage of the pneumatic control member 42 is cut off, stopping the output of pressurized gas to the pneumatic drive member 41. The power output end of the pneumatic drive member 41 automatically resets, driving the drive rod 33 to rotate in the opposite direction to reset, driving the first clamping member 31 and the second clamping member 32 to slide in the opposite direction along the bracket 2 to close, forming a continuous and constant clamping force on the round glass covers in the space.

[0049] Referring to Figure 3, handles 24 are fixedly installed on both sides of the bracket 2, providing multiple gripping points for the overall transfer of the main body 1 of the rotating jig. This adapts to the gripping and operation needs of operators in different process positions and different placement directions. The bracket 2 is provided with a mounting plate 23, which is located between the handles 24 on both sides of the bracket 2. The pneumatic control component 42 is located at one end of the handle 24 near the mounting plate 23, specifically at the end of the mounting plate 23 near the pneumatic drive component 41. This integrates the operating point of the pneumatic control component 42 with the gripping point of the handle 24. When the operator grips the handle 24 to transfer the main body 1 of the rotating jig or to perform loading and unloading operations, they can directly operate the pneumatic control component 42 and switch the clamping and releasing states of the main body 1 of the rotating jig with one key.

[0050] Referring to Figure 3, the pneumatic control component 42 and the mounting plate 23 are detachably fixedly connected, and the handle 24 is detachably fixedly connected to the bracket 2. The pneumatic control component 42 and the mounting plate 23 are detachably connected by screws. Both sides of the bracket 2 are set as cylindrical rod structures, and each end of the bracket 2 corresponds to a handle 24. Referring to Figure 6, each handle 24 is provided with a fixing part 241 at both ends. The fixing part 241 is used to realize the detachable fixing of the handle 24 to the end of the bracket 2 and the adjustment of the installation angle.

[0051] Referring to Figure 6, the fixing part 241 includes two vertically arranged and opposing clamping arms 2411. Each clamping arm 2411 has a semi-circular mounting groove 24111 on its opposite sidewall. The mounting grooves 24111 of the two clamping arms 2411 are coaxially arranged and opposite each other, forming a complete circular mounting hole 2412. During installation, the two sides of the bracket 2 pass through the mounting hole 2412 formed by the two clamping arms 2411. Then, the locking bolts are passed through the two clamping arms 2411 in sequence and tightened. During the tightening process, the two clamping arms 2411 are driven to tighten towards each other, and the clamping force firmly fixes the fixing part 241 to the bracket 2. When it is necessary to adjust the installation angle of the handle 24 relative to the bracket 2, simply loosen the locking bolt, release the clamping arms 2411 from the bracket 2, and then rotate the handle 24 circumferentially around the central axis on both sides of the bracket 2. After adjusting the handle 24 to the target installation angle, tighten the locking bolt again, and the clamping arms 2411 clamp and fix it again, thus completing the adjustment and locking of the installation angle of the handle 24.

[0052] Furthermore, the handle 24 is detachably fixed to the bracket 2, and the pneumatic control component 42 and the mounting plate 23 are detachably fixed, which facilitates individual disassembly and replacement when wear and tear occurs, reducing the maintenance cost of the main body 1 of the rotating fixture. The mounting angle of the handle 24 relative to the bracket 2 is adjustable and lockable. The handle 24 can be adjusted to a suitable mounting angle according to the operator's operating habits and grip posture. After adjustment, it is locked and fixed. When adjusting the mounting angle of the handle 24, the pneumatic control component 42 adjusts its position synchronously with the handle 24, so that the operating point of the pneumatic control component 42 is always adapted to the operator's grip posture.

[0053] The implementation principle of the rotating jig for a plate-shaped product in this application embodiment is as follows: The operator holds the handles 24 at both ends of the bracket 2 and presses down the pressing rod 421 of the pneumatic control component 42. The internal air passage of the pneumatic control component 42 is opened, and the external air source inputs pressurized gas to the pneumatic drive component 41 through the pneumatic control component 42. The pressurized gas drives the piston rod of the pneumatic drive component 41 to extend, further driving the transmission block 411 to move. Through the connecting rod 4111, the transmission rod 33 is driven to rotate around the pivot point of the rotating shaft connected to the bracket 2.

[0054] When the transmission rod 33 rotates around the pivot point, the two ends of the transmission rod 33 generate opposite displacements along the extension direction of the guide post 211, which synchronously drives the first clamping member 31 and the second clamping member 32 to slide in opposite directions along the guide post 211: the first clamping member 31 slides towards the pneumatic drive member 41, and the second clamping member 32 slides away from the pneumatic drive member 41. During this process, the first boss 312 of the first clamping member 31 and the second boss 322 of the second clamping member 32 are always in contact with the upper surface of the bearing plate 21, which constrains the vertical positional offset of the first clamping member 31 and the second clamping member 32. The guide post 211 and the sliding groove 5 are fitted together to constrain the radial movement and angular offset of the clamping members, ensuring that the first clamping member 31 and the second clamping member 32 slide in parallel and synchronously throughout the entire process.

[0055] When the piston rod of the pneumatic drive 41 extends to the preset stroke, the transmission block 411 abuts against the end face of the limiting plate 22 on the bracket 2, preventing the piston rod of the pneumatic drive 41 from extending further and completing the limit of the maximum opening and closing stroke. At this time, the first clamping piece 311 abuts against the adjacent second clamping piece 321 on the side close to the pneumatic drive 41. Multiple sets of uniformly sized and spaced accommodating spaces are formed between the first clamping piece 311 and the adjacent second clamping piece 321 on the side away from the pneumatic drive 41. Each set of accommodating spaces corresponds one-to-one with the circular glass cover of the smart wearable product to be turned over. The operator holds the handles 24 at both ends of the bracket 2 to adjust the position of the rotating jig body 1 so that each set of accommodating spaces is aligned with the multiple circular glass cover plates to be turned over. Then, the rotating jig body 1 is moved along the opening direction of the accommodating space so that all the circular glass cover plates to be turned over enter the corresponding accommodating space simultaneously.

[0056] After the batch loading is completed, the operator releases the pressing rod 421 of the pneumatic control component 42. The internal air passage of the pneumatic control component 42 is cut off, and the output of pressurized gas to the pneumatic drive component 41 stops. The piston rod of the pneumatic drive component 41 automatically resets and retracts. Through the transmission block 411 and the connecting rod 4111, the transmission rod 33 is driven to rotate in the opposite direction around the rotation fulcrum to reset. This drives the first clamping component 31 to slide away from the pneumatic drive component 41, and the second clamping component 32 to slide closer to the pneumatic drive component 41.

[0057] During the sliding closure process, the distance between the first clamping piece 311 and the second clamping piece 321 on the side away from the pneumatic drive member 41 gradually decreases until the first clamping piece 311 and the second clamping piece 321 on the side away from the pneumatic drive member 41 clamp and abut against the side wall of the circular glass cover, thereby forming a continuous and constant clamping force on the circular glass cover in the accommodating space, completing the synchronous and stable clamping of multiple circular glass covers. The clamping force is provided by the constant force of the pneumatic drive member 41 in the reset state, without the need for continuous air supply from the pneumatic control member 42. The clamping force will not decrease with the increase of the number of uses of the rotating fixture body 1, and the stability of the clamping state can be maintained throughout the process. At the same time, the semi-circular blunt structure at the ends of the first clamping piece 311 and the second clamping piece 321 can reduce scratches on the surface of the glass cover and chipping of the glass cover edges during the clamping process.

[0058] Subsequently, the operator holds the main body 1 of the rotating fixture by the handle 24 and transfers the main body 1 of the rotating fixture, which holds the circular glass cover plates, to the next process station. First, all the circular glass cover plates on the main body 1 of the rotating fixture are aligned with the corresponding placement positions of the next process. Then, the operator presses the pressing rod 421 of the pneumatic control component 42 again to repeat the pneumatic transmission process of opening the main body 1 of the rotating fixture, driving the first clamping component 31 and the second clamping component 32 to slide in opposite directions to open, releasing the clamping limit on the circular glass cover plates, so that the circular glass cover plates fall smoothly from the receiving space into the corresponding placement positions of the next process, completing the batch unloading operation. The operator releases the pressing rod 421, the pneumatic drive component 41 resets, and the next batch of circular glass cover plates enters the turnover operation cycle.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
