Description

Technical Field

[0001] This application relates to the field of glass production technology, and in particular to a glass mold outer circle positioning mechanism. Background Technology

[0002] Glass molds are tools used for forming glass products. Their cross-section is usually semi-circular. To achieve centralized transportation and efficient storage of multiple glass molds, multiple glass molds need to be placed on the same carrier. By moving the carrier, these glass molds can be transported to the designated processing or storage area simultaneously. At the same time, since the subsequent processing steps of glass molds have high precision requirements, it is necessary to ensure that the horizontal plane of the glass mold is placed upwards to meet the requirements of its posture during processing.

[0003] In the prior art, in order to keep the glass mold in the correct position on the carrier plate, a semi-circular groove matching the cross-sectional shape of the glass mold is usually opened on the surface of the carrier plate. By embedding the glass mold into the semi-circular groove, the shape of the groove restricts the position of the glass mold to be aligned. However, during the process of removing the glass mold from the semi-circular groove, the opening of the groove will hinder the gripping and placement actions of the robot or human hand, resulting in a reduction in the loading and unloading efficiency of the glass mold, thereby reducing the overall processing efficiency of the glass mold, which has obvious shortcomings. Utility Model Content

[0004] In order to improve the loading and unloading efficiency of glass molds on the carrier plate, this application provides a glass mold outer circle positioning mechanism.

[0005] The glass mold outer circle positioning mechanism provided in this application adopts the following technical solution: A glass mold outer circle positioning mechanism includes a carrier plate on which multiple mounting plates are arranged in an array. Each mounting plate is provided with a positioning component. The positioning component includes two supports arranged opposite each other. One support is provided with a first clamping member for clamping the mold, and the opposite support is provided with a second clamping member that cooperates with the first clamping member. Positioning wheels are rotatably connected to opposite sides of the supports along their own length direction. The positioning wheels abut against the outer circle surface of the glass mold.

[0006] By adopting the above technical solution, when in use, the glass mold is placed between two supports. The first and second clamping components provide clamping force for the placed glass mold, improving the stability of the glass mold on the carrier plate. The arc surface of the glass mold fits into the positioning wheels. When the initial placement posture of the glass mold is tilted, causing the horizontal plane to not face upward, its outer circular surface forms an asymmetrical contact with the positioning wheels on both sides. Under the weight of the glass mold itself, the tilted glass mold will push the contacting positioning wheels to rotate. The rotation of the positioning wheels applies a reverse corrective force to the outer circle of the glass mold, causing the glass mold to gradually adjust its placement angle until the horizontal plane of the glass mold is kept facing upward. This achieves the adjustment of the glass mold's posture, and there is no need to open a semi-circular material groove on the carrier plate, avoiding the material groove from hindering the action of the robot or human hand to grasp and place the glass mold. This makes the loading and unloading process of the glass mold smoother and more convenient, improving the loading and unloading efficiency of the glass mold.

[0007] Optionally, the first clamping member includes a spring piece disposed on the support, the spring piece having its elastic force direction facing the other side of the support; the second clamping member includes a spring seat disposed on the support, the spring seat having multiple spring cavities on the side facing the spring piece, a telescopic rod slidably connected in the spring cavity, a spring disposed in the spring cavity, the elastic force of the spring driving the telescopic rod part to protrude out of the spring cavity.

[0008] By adopting the above technical solution, before placement, the worker reverses the spring to leave space for the glass mold. Then, the glass mold is placed between the two supports. After the spring is released, it abuts against one side of the glass mold under its own elastic force. At the same time, the other side of the glass mold squeezes the telescopic rod, causing the telescopic rod to compress the spring. When the spring is compressed, it generates a reverse elastic force, driving the telescopic rod to always fit tightly against the surface of the glass mold, forming an elastic clamping on both sides of the glass mold.

[0009] Optionally, each of the positioning wheels is fitted with a rubber sleeve on its outer surface.

[0010] By adopting the above technical solution, the rubber sleeve transforms the hard contact between the glass mold and the positioning wheel into a flexible contact, avoiding direct friction between the positioning wheel material and the mold surface, reducing the possibility of scratches and other damage on the outer circle of the glass mold, and ensuring the surface accuracy of the glass mold.

[0011] Optionally, each of the supports is provided with a sliding groove along its length, and a sliding block corresponding to the positioning wheel is slidably connected in each sliding groove. The positioning wheel is rotatably mounted on the corresponding sliding block. An adjustment component is provided on the mounting plate, which is used to drive two sliding blocks in the same support to move towards or away from each other.

[0012] By adopting the above technical solution, when it is necessary to adapt to glass molds with different outer diameters, the worker can adjust the components to drive the sliding blocks in the same support to move towards or away from each other. The sliding blocks drive the positioning wheels to move, thereby adjusting the distance between the two positioning wheels on the same support, so that the two sets of positioning wheels can adapt to the outer diameter of the glass mold of the corresponding size, ensuring that the positioning wheels can keep in contact with the outer surface of the glass mold of different sizes, thereby improving the applicability of the positioning components.

[0013] Optionally, the mounting plate is provided with an adjustment groove, and an adjustment block corresponding to each of the two supports is slidably connected in the adjustment groove. Each adjustment block is hinged with an adjustment rod corresponding to each of the two sliding blocks. The end of the adjustment rod is hinged to the corresponding sliding block. A bidirectional lead screw is rotatably connected to the adjustment groove along its length. The two adjustment blocks are respectively threaded to two sections of the bidirectional lead screw with opposite thread directions. The end of the bidirectional lead screw extends out of the mounting plate and is coaxially provided with a handwheel.

[0014] By adopting the above technical solution, when adjustment is required, the worker rotates the handwheel to drive the bidirectional lead screw to rotate. Under the guide limit of the adjustment groove, the bidirectional lead screw drives the two adjustment blocks to slide synchronously in opposite or the same direction along the adjustment groove. When the adjustment blocks move, the included angle between the adjustment rod and the axis of the bidirectional lead screw changes. The adjustment rod pushes or pulls the corresponding sliding block to move in the sliding groove, thereby realizing the adjustment of the positioning wheel spacing. When the positioning wheel spacing matches the outer circle size of the glass mold, the adjustment is completed. The setting of the adjustment component realizes the synchronous adjustment of the positioning wheel spacing on the two supports, keeps the positioning wheel spacing adjustment symmetrical, avoids uneven contact between the positioning wheel and the outer circle of the mold due to unilateral adjustment deviation, and ensures that the positioning wheel can symmetrically abut against the outer circle of the mold.

[0015] Optionally, each of the mounting plates is detachably connected to the carrier plate via a plurality of the connecting components.

[0016] By adopting the above technical solution, when the positioning component on the mounting plate is damaged, the worker can remove the mounting plate on the damaged positioning component through the connecting component, and then install the mounting plate with the new positioning component on the carrier plate. This eliminates the need to disassemble or replace the entire carrier plate, thus improving the worker's maintenance efficiency.

[0017] Optionally, the connecting assembly includes a plug-in post disposed on a carrier plate, and a plug-in groove is provided on the mounting plate to engage with the plug-in post. Multiple retaining strips are provided circumferentially at the ends of the plug-in post away from the carrier plate. A hook block is provided at the end of each retaining strip, and an inclined surface is provided on the hook block. Both the retaining strips and the hook block are made of elastic material. When the retaining strips and the hook block are in their natural state, the retaining strips abut against the inner sidewall of the plug-in groove, and the hook block extends out of the plug-in groove and abuts against the surface of the mounting plate.

[0018] By adopting the above technical solution, during installation, the insertion slot is aligned with the insertion post and pressed downwards. The inclined surface of the hook block contacts the edge of the insertion slot and is squeezed. Under the squeezing force, the retaining strip and hook block retract towards the center of the insertion post, allowing the insertion post to be smoothly inserted into the insertion slot. When the insertion post is inserted to the bottom, the retaining strip and hook block lose the squeezing force and return to their natural state. The retaining strip abuts against the inner wall of the insertion slot, restricting the horizontal movement of the mounting plate. The hook block extends out of the insertion slot and abuts against the surface of the mounting plate, preventing the mounting plate from detaching from the insertion post in the vertical direction, thus completing the connection between the mounting plate and the carrier plate. During disassembly, the worker pinches the two hook blocks, causing the retaining strip and hook block to retract towards the center of the insertion post again. The hook block detaches from the surface of the mounting plate and retracts into the insertion slot. At this time, the mounting plate is pulled upwards to separate the insertion slot from the insertion post, completing the disassembly. The entire disassembly and assembly process does not require any tools, making the operation simple and convenient, and improving the efficiency of workers during maintenance.

[0019] Optionally, it also includes a frame for loading the trays, wherein multiple trays are arranged in the height direction of the frame, and electric guide rails are provided on the opposite inner sidewalls of the frame, and the opposite sides of the trays are mounted on the electric guide rails.

[0020] By adopting the above technical solution, the arrangement of multiple carrier trays utilizes the vertical space of the frame, increasing the storage capacity of glass molds. At the same time, workers can control the electric guide rails to drive the carrier trays to move, realizing the automated transfer of carrier trays.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application replaces the material groove on the carrier plate with a positioning component. In use, when the glass mold is placed between the two supports, the first clamping member and the second clamping member provide clamping force for the placed glass mold. The arc surface of the glass mold is in contact with the positioning wheel. When the glass mold is initially tilted and the horizontal plane is not facing upward, its outer circular surface forms an asymmetrical contact with the positioning wheels on both sides. Under the weight of the glass mold itself, the tilted glass mold will push the contacting positioning wheel to rotate. The rotation of the positioning wheel applies a reverse corrective force to the outer circle of the glass mold, causing the glass mold to gradually adjust its placement angle until the horizontal plane of the glass mold is in an upward posture. In this way, the posture of the glass mold can be adjusted. Moreover, there is no need to open a semi-circular material groove on the carrier plate, which avoids the material groove from hindering the action of the robot or human hand to grasp and place the glass mold. This makes the loading and unloading process of the glass mold smoother and more convenient, and improves the loading and unloading efficiency of the glass mold. 2. By setting an adjustment component, when it is necessary to adapt to glass molds with different outer diameters, the worker drives the sliding block in the same support to move towards or away from each other through the adjustment component. The sliding block drives the positioning wheel to move, thereby adjusting the distance between the two positioning wheels on the same support, so that the two sets of positioning wheels can adapt to the outer diameter of the glass mold of the corresponding size, ensuring that the positioning wheel can keep in contact with the outer diameter surface of the glass mold of different sizes, thereby improving the applicability of the positioning component; 3. By setting up a connecting component, when the positioning component on the mounting plate is damaged, the worker can remove the mounting plate on the damaged positioning component through the connecting component, and then install the mounting plate of the new positioning component on the carrier plate. This eliminates the need to disassemble or replace the entire carrier plate, thus improving the worker's maintenance efficiency. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a glass mold outer circle positioning mechanism.

[0030] Reference Figure 1 A glass mold outer circle positioning mechanism includes a gantry-shaped frame 1. Multiple electric guide rails 101 are installed on the inner sidewalls of the frame 1 along the height direction. In this embodiment, there are three electric guide rails 101. The electric guide rails 101 are linear drive devices commonly used in the prior art. The specific composition and principle will not be described in this embodiment. A carrier plate 2 for placing the glass mold is installed on two electric guide rails 101 at the same height.

[0031] When using glass molds, workers place multiple glass molds on the carrier plate 2. When movement is required, the electric guide rail 101 is activated to move the carrier plate 2, thereby realizing the automated transfer of glass molds.

[0032] Reference Figure 1 and Figure 2 Multiple mounting plates 3 are detachably mounted in an array on the carrier plate 2. In this embodiment, three mounting plates 3 are arranged in the length direction of the carrier plate 2 and two are arranged in the width direction. Each mounting plate 3 is provided with a positioning component 4. The positioning component 4 includes two supports 41 arranged opposite to each other along the width direction of the carrier plate 2. One support 41 is provided with a first clamping member 42 for clamping the mold, and the opposite support 41 is provided with a second clamping member 43. The first clamping member 42 and the second clamping member 43 respectively abut against the opposite end faces of the glass mold. The first clamping member 42 is a spring piece 421 installed on the support 41. The elastic force of the spring piece 421 is directed towards the other support 41.

[0033] Reference Figure 3 and Figure 4The second clamping member 43 includes a spring seat 431 installed in the middle of the support 41. The spring seat 431 is L-shaped. A plurality of spring cavities 4311 are opened vertically on the side of the spring seat 431 near the spring piece 421. In this embodiment, there are three spring cavities 4311. A telescopic rod 432 is slidably connected inside each spring cavity 4311. Limiting blocks (not shown in the figure) are fixedly connected to both radially opposite sides of the telescopic rod 432. A limiting groove (not shown in the figure) is opened on the inner side wall of the spring cavity 4311 to slide with the limiting block. The sliding cooperation between the limiting block and the limiting groove restricts the movement stroke of the telescopic rod 432 and prevents the telescopic rod 432 from coming out of the spring cavity 4311. A spring 433 is provided inside the spring cavity 4311. One end of the spring 433 is fixedly connected to the bottom wall of the inner wall of the spring cavity 4311, and the other end is fixedly connected to the telescopic rod 432. The elastic force of the spring 433 drives the telescopic rod 432 to protrude part of the spring cavity 4311.

[0034] Reference Figure 3 and Figure 4 The support 41 is rotatably connected to two opposite sides along its own length direction with positioning wheels 44. Each positioning wheel 44 is fitted with a rubber sleeve 441 on its outer surface. The rubber sleeve 441 abuts against the outer circle surface of the glass mold. The rubber sleeve 441 transforms the hard contact between the glass mold and the positioning wheel 44 into a flexible contact, avoiding direct friction between the material of the positioning wheel 44 and the mold surface, and reducing the possibility of scratches and other damage on the outer circle of the glass mold.

[0035] Before placement, the worker reverses the spring piece 421 to make room for the glass mold. Then, the glass mold is placed between the two supports 41. After the spring piece 421 is released, it abuts against one side of the glass mold under its own elastic force. At the same time, the other side of the glass mold squeezes the telescopic rod 432, causing the telescopic rod 432 to compress the spring 433. When the spring 433 is compressed, it generates a reverse elastic force, which drives the telescopic rod 432 to fit against the surface of the glass mold, forming an elastic clamp on both sides of the glass mold, thereby improving the stability of the glass mold on the carrier plate 2. After the glass mold is placed, the positioning wheel 44 fits against the arc surface of the glass mold. When the initial placement posture of the glass mold is tilted, causing the horizontal plane to not face upward, its outer circular surface forms an asymmetrical contact with the positioning wheels 44 on both sides. Under the weight of the glass mold itself, the tilted glass mold will push the contacting positioning wheel 44 to rotate. The rotation of the positioning wheel 44 applies a reverse corrective force to the outer circle of the glass mold, causing the glass mold to gradually adjust its placement angle until the horizontal plane of the glass mold is kept facing upward. This achieves the adjustment of the glass mold's posture, and there is no need to open a semi-circular material groove on the carrier plate 2, avoiding the material groove from hindering the action of the robot or human hand to grasp and place the glass mold. This makes the loading and unloading process of the glass mold smoother and more convenient, and improves the loading and unloading efficiency of the glass mold.

[0036] Reference Figure 4and Figure 5 Each support 41 has a sliding groove 5 along its length. Each sliding groove 5 has a sliding block 51 that corresponds to one of the two positioning wheels 44. The cross-section of the sliding block 51 and the sliding groove 5 is T-shaped, and the end of the sliding block 51 protrudes from the sliding groove 5. The positioning wheel 44 is rotatably mounted on the corresponding sliding block 51. An adjustment component 6 is provided on the mounting plate 3.

[0037] Reference Figure 4 and Figure 5 The adjusting assembly 6 includes a bidirectional lead screw 61. The end of the bidirectional lead screw 61 extends out of the mounting plate 3 and is coaxially fixedly connected to a handwheel 611. The mounting plate 3 has an adjusting groove 31 that rotates with the bidirectional lead screw 61. The adjusting groove 31 is perpendicular to the sliding groove 5. The two sections of the bidirectional lead screw 61 with opposite thread directions are threadedly connected to adjusting blocks 62. The two adjusting blocks 62 are slidably connected in the adjusting groove 31 and are corresponding to the two supports 41. The sliding block 51 and the sliding groove 5 have square cross-sections to limit the rotational movement of the sliding block 51. Each adjusting block 62 is hinged with an adjusting rod 63 that corresponds to the two sliding blocks 51 in the corresponding support 41. The end of the adjusting rod 63 away from the adjusting block 62 is hinged to the corresponding sliding block 51.

[0038] When it is necessary to adapt to glass molds with different outer diameters, the worker turns the handwheel 611 to drive the bidirectional lead screw 61 to rotate. Under the guidance and limit of the adjustment groove 31, the bidirectional lead screw 61 drives the two adjustment blocks 62 to slide synchronously in opposite or the same direction along the adjustment groove 31. When the adjustment block 62 moves, the included angle between the adjustment rod 63 and the axis of the bidirectional lead screw 61 changes. The adjustment rod 63 pushes or pulls the corresponding sliding block 51 to move in the sliding groove 5. The sliding block 51 drives the positioning wheel 44 to move, thereby adjusting the distance between the two positioning wheels 44 on the same support 41, so that the two sets of positioning wheels 44 can adapt to the outer diameter of the glass mold of the corresponding size, ensuring that the positioning wheel 44 can keep in contact with the outer diameter surface of the glass mold of different sizes, thereby improving the applicability of the positioning component 4.

[0039] Reference Figure 4 and Figure 5 Each mounting plate 3 is detachably mounted on the carrier plate 2 via multiple connecting components 7. In this embodiment, a mounting plate 3 is detachably mounted on the carrier plate 2 via two connecting components 7, with the two connecting components 7 located on opposite sides of the mounting plate 3. When the positioning component 4 on the mounting plate 3 is damaged, the worker removes the mounting plate 3 from the damaged positioning component 4 via the connecting components 7, and then installs the mounting plate 3 with a new positioning component 4 onto the carrier plate 2. This eliminates the need to disassemble or replace the entire carrier plate 2, thus improving the worker's maintenance efficiency.

[0040] Reference Figure 4 and Figure 5The connecting component 7 includes a plug-in post 71 fixedly connected to the carrier plate 2. The mounting plate 3 has a plug-in groove 32 that engages with the plug-in post 71. Multiple retaining strips 72 are evenly connected circumferentially at the ends of the plug-in post 71 away from the carrier plate 2. In this embodiment, two retaining strips 72 are provided at both ends of the plug-in post 71 in the radial direction. Each retaining strip 72 has a hook block integrally formed at the end away from the carrier plate 2. Each hook block has an inclined surface that facilitates the insertion of the plug-in post 71 into the plug-in groove 32. Both the retaining strips 72 and the hook blocks are made of elastic material. When the two retaining strips 72 are in their natural state, the area of ​​the two hook blocks spliced ​​together is greater than the cross-sectional area of ​​the plug-in groove 32, thereby restricting the vertical displacement of the plug-in post 71 in the plug-in groove 32.

[0041] When the positioning component 4 on the mounting plate 3 is damaged, the worker pinches the two hook blocks, causing the locking strip 72 and the hook blocks to retract towards the center of the insertion post 71. The hook blocks detach from the surface of the mounting plate 3 and retract into the insertion groove 32. At this time, the mounting plate 3 is pulled upward to separate the insertion groove 32 from the insertion post 71, completing the disassembly of the damaged positioning component 4. Subsequently, the worker aligns the insertion groove 32 on the new mounting plate 3 with the insertion post 71 and presses the mounting plate 3 downward. The inclined surface of the hook block contacts the edge of the insertion groove 32 and is squeezed. Under the pressure, the retaining strip 72 and the hook block retract toward the center of the insertion post 71, allowing the insertion post 71 to be smoothly inserted into the insertion slot 32. When the insertion post 71 is inserted to the bottom, the retaining strip 72 and the hook block lose the pressure and return to their natural state. The retaining strip 72 abuts against the inner wall of the insertion slot 32, restricting the mounting plate 3 from swaying in the horizontal direction. The hook block extends out of the insertion slot 32 and abuts against the surface of the mounting plate 3, preventing the mounting plate 3 from detaching from the insertion post 71 in the vertical direction, thereby completing the connection between the mounting plate 3 and the carrier plate 2.

[0042] The implementation principle of the glass mold outer circle positioning mechanism in this application embodiment is as follows: Before placement, the worker reverses the spring piece 421 to leave space for the glass mold. Then, the glass mold is placed between two supports 41. After the spring piece 421 is released, it abuts against one side of the glass mold under its own elastic force. At the same time, the other side of the glass mold squeezes the telescopic rod 432, causing the telescopic rod 432 to compress the spring 433. When the spring 433 is compressed, it generates a reverse elastic force, driving the telescopic rod 432 to fit against the surface of the glass mold, forming an elastic clamping on both sides of the glass mold, thereby improving the stability of the glass mold on the carrier plate 2. After the glass mold is placed, the positioning wheel 44 fits against the arc surface of the glass mold. When the initial placement posture of the glass mold is tilted, causing the horizontal plane to not face upward, its outer circular surface forms an asymmetrical contact with the positioning wheels 44 on both sides. Under the weight of the glass mold itself, the tilted glass mold will push the contacting positioning wheel 44 to rotate. The rotation of the positioning wheel 44 applies a reverse corrective force to the outer circle of the glass mold, causing the glass mold to gradually adjust its placement angle until the horizontal plane of the glass mold is kept facing upward. This achieves the adjustment of the glass mold's posture, and there is no need to open a semi-circular material groove on the carrier plate 2, avoiding the material groove from hindering the action of the robot or human hand to grasp and place the glass mold. This makes the loading and unloading process of the glass mold smoother and more convenient, and improves the loading and unloading efficiency of the glass mold.

[0043] 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.
