Description

Technical Field

[0001] This utility model relates to the field of glass mold testing technology, and in particular to a non-contact glass mold cavity volume rapid testing mechanism. Background Technology

[0002] Glass molds are the core forming tools in the glass bottle and jar production process, and the accuracy of their cavity volume directly determines the final product's capacity specifications. During mold production and maintenance, their volume must be rigorously tested. Traditional testing methods primarily rely on the water injection method, which involves injecting liquid into the mold cavity and calculating the mold volume by weighing or measuring the liquid volume with a measuring cup. However, this contact-based measurement method is inefficient and cannot meet the fast-paced demands of large-scale production. Furthermore, liquid media can easily remain inside the mold, causing contamination or corrosion, and the subjective errors inherent in manual operation make it difficult to guarantee the repeatability and accuracy of the data.

[0003] With the development of machine vision technology, non-contact measurement based on 3D scanning is gradually becoming a trend. This technology typically requires placing the mold on a rotating platform and acquiring omnidirectional point cloud data of the mold through an external scanner for integration calculation. However, most existing rotating inspection platforms have simple structures and lack dedicated support and positioning mechanisms designed for heavy glass molds. When bearing heavy molds, ordinary single-axis support structures are prone to slight tilting or swaying, resulting in misalignment of scanned data and affecting measurement accuracy.

[0004] Therefore, this utility model proposes a non-contact glass mold cavity volume rapid detection mechanism to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of low efficiency and easy contamination of the mold by contact measurement in existing glass mold inspection equipment, and the lack of stable multi-point support structure in existing automated rotary inspection platforms when carrying heavy molds, resulting in poor rotational stability, this utility model aims to provide a non-contact glass mold cavity volume rapid detection mechanism with improved structure that can effectively solve the above problems.

[0006] This utility model provides a non-contact glass mold cavity volume rapid detection mechanism, including a base, an operating table, a scanner, a motor disposed inside the base, a gear fixed to the output shaft of the motor, and a positioning mechanism disposed on the top surface of the operating table.

[0007] The positioning mechanism has a linkage transmission structure that converts linear drive into translational clamping. The positioning mechanism includes an air pump fixedly connected to the operating table. A first fixing block is fixedly connected to the housing of the air pump. A first fixing column serving as a guide rail is horizontally fixedly connected to the first fixing block. A second fixing block for clamping the mold is slidably connected to the outer surface of the first fixing column. A connecting plate is connected between the output end of the air pump and the second fixing block.

[0008] Furthermore, the operating platform is rotatably connected to the top of the base, and the gears inside the base mesh with the outer periphery of the operating platform. The center of the operating platform and the base are connected via a rotating mechanism. The air pump drives the connecting plate to move, and the connecting plate in turn pulls the second fixing block to slide along the first fixing column, thereby achieving positioning and clamping of the mold placed on the operating platform. The scanner is fixedly mounted on one side of the base via a bracket and located above the operating platform for data acquisition from the rotating mold.

[0009] Preferably, the rotating mechanism has a design to enhance rotational concentricity, including a limiting post fixedly connected to the center of the top surface of the base, and a pivot hole opened in the center of the operating table. The operating table is rotatably sleeved on the outer surface of the limiting post through the pivot hole, and the radial displacement of the operating table is limited by the limiting post.

[0010] Preferably, the operating platform further includes an auxiliary support structure for improving load-bearing stability. The outer side wall of the operating platform is provided with an annular groove. Several third fixed columns arranged in a ring are fixedly connected to the top surface of the base. Each third fixed column is rotatably connected to a roller at its top. The roller rolls and engages with the inside of the groove. Through the engagement of the roller and the groove, edge support is provided for the operating platform to prevent it from tipping over when carrying heavy objects.

[0011] Preferably, the connection between the connecting plate and the driving component is a double-pin flexible connection. Each end of the connecting plate is provided with a second fixing post. The connecting plate is rotatably connected to the output end of the air pump through one of the second fixing posts and rotatably connected to the second fixing block through the other second fixing post. This structure can eliminate the risk of jamming caused by installation errors and ensure smooth transmission.

[0012] Preferably, the second fixing block is made of metal material, and a rubber pad is fixedly connected to its side wall away from the first fixing block. The rubber pad is used to directly abut against the outer wall of the glass mold to be tested, and its elastic deformation protects the mold surface from being crushed.

[0013] Preferably, the base further includes a component for stabilizing the installation foundation, and foot pads are fixedly connected to the four corners of the bottom surface of the base. The bottom of the foot pads is provided with anti-slip texture to increase friction and prevent the equipment from shifting during operation.

[0014] Preferably, a low-friction component is provided at the mating point between the first fixing post and the second fixing block, the first fixing post is disposed through the interior of the second fixing block, and a linear bearing is provided at the connection point between the second fixing block and the first fixing post to reduce sliding friction resistance and improve response speed.

[0015] Preferably, the scanner's mounting angle is optimized, with the scanner's lens tilted towards the rotation center of the operating table, so that the line of sight can penetrate deep into the mold, thereby collecting complete data on the bottom of the cavity.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of low efficiency, inaccurate positioning, and easy damage to the surface of glass molds by setting a positioning mechanism driven by an air pump on the operating table. It utilizes a connecting plate and a fixed column to convert the linear telescopic motion of the air pump into the translational clamping action of the fixed block. With the help of an elastic rubber pad, it solves the problems of low efficiency, inaccurate positioning, and easy damage to the surface of glass molds by rigid clamps in the prior art. It achieves the technical effects of rapid automated positioning, effective buffering of clamping impact, and protection of the appearance quality of the mold.

[0017] 2. This utility model solves the problem of tilting and shaking that easily occurs when a traditional rotary platform is carrying heavy molds, resulting in misalignment of scanned data, by opening an annular sliding groove on the outer wall of the operating table and setting multiple evenly distributed rollers on the base to roll in cooperation with the sliding groove, while cooperating with the limiting post at the center position for radial limiting. This achieves the technical effect of improving rotational stability, enhancing load-bearing capacity and ensuring volume detection accuracy.

[0018] 3. This utility model, by using a rotating operating table driven by a motor and gears in conjunction with an inclined non-contact scanner, achieves all-round data acquisition of the inside and outside of the mold cavity. It solves the problems of cumbersome operation, low efficiency, easy contamination of the mold, and difficulty in achieving automated detection in the traditional water injection method for measuring volume. It achieves the technical goal of fast, non-destructive and high-precision cavity volume detection. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 This utility model provides a non-contact glass mold cavity volume rapid detection mechanism, which aims to solve the problems of low efficiency and easy physical damage to the mold caused by contact measurement in existing glass mold detection technology, as well as the lack of effective stable support for heavy molds by traditional rotary detection platforms, resulting in insufficient accuracy of scanning data splicing.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the main structure of the non-contact glass mold cavity volume rapid detection mechanism includes a base 5 as the mounting base, an operating table 3 rotatably connected to the top of the base 5, and a scanner 7 fixed to one side of the base 5 and suspended above the operating table 3 by a bracket. The base 5 mainly serves to support the weight of the entire mechanism and to install the drive components. Foot pads 6 are fixedly connected to the four corners of its bottom surface by bolts. The bottom surface of the foot pads 6 is processed with anti-slip texture to increase the friction with the ground and ensure the positional stability of the device during operation.

[0024] A motor 202, providing rotational power, is fixedly installed in the internal cavity of the base 5 by bolts. A gear 201 is fixedly connected to the end of the output shaft of the motor 202 by a key. Correspondingly, a full circle of outer peripheral teeth is machined on the outer circumferential side wall of the operating table 3. The gear 201 is meshed with the outer peripheral teeth on the outside of the operating table 3. After the motor 202 is started, it drives the gear 201 to rotate, thereby driving the operating table 3 to perform circumferential motion relative to the base 5, providing rotational feed for the all-round scanning of the mold. A rotating mechanism 2 is provided between the center of the operating table 3 and the base 5.

[0025] To ensure the stability and concentricity of the operating table 3 during rotation and to prevent tilting or wobbling of the turntable due to mold eccentricity, a limit post 205 is vertically welded or bolted to the geometric center of the top surface of the base 5. A pivot hole is correspondingly opened at the center of the bottom surface of the operating table 3. The operating table 3 is rotated and fitted onto the outer surface of the limit post 205 through the pivot hole. The limit post 205 acts as a radial limit, establishing the rotation axis of the operating table 3. At the same time, an annular groove 4 extending in the circumferential direction is opened on the outer cylindrical side of the operating table 3. Several third fixed posts 204 are fixedly connected in a ring array around the limit post 205 on the top surface of the base 5. In order to enhance the rotational stability of the operating table 3 when bearing heavy glass molds, the number of third fixed posts 204 is preferably three or more, and they are evenly distributed.

[0026] Each third fixed column 204 has a roller 203 rotatably connected to its top via a pin. The roller 203 extends into and rolls inside the slide groove 4. The outer diameter of the roller 203 and the width of the slide groove 4 are fitted with a clearance fit or a slight interference fit, which limits the radial runout of the roller 203 in the groove. This structure makes the roller 203 form a structure similar to a slewing bearing when it rolls in the slide groove 4. This not only effectively distributes the vertical load of the operating table 3 and the mold under test, but also limits the axial movement of the operating table 3, ensuring dynamic balance performance during high-speed rotation.

[0027] The scanner 7 is fixed at a preset angle by a bracket. In order to ensure that the data inside the deep cavity mold can be fully collected, its lens is tilted towards the rotation center of the operating table 3. The specific tilt angle can be preset according to the average depth-to-diameter ratio of the mold to be tested, so as to cover the cavity opening and internal area of ​​the glass mold placed in the center of the operating table 3. With the rotation of the operating table 3, the complete collection of internal and external data of the mold can be achieved.

[0028] like Figure 1 and Figure 3As shown, the mechanism also integrates a positioning mechanism 1 on the operating table 3. The positioning mechanism 1 has an air pump 101 as a power output end. The air pump 101 is horizontally fixed to the upper surface of the operating table 3 by screws and is located within the inner circle of the slide groove 4. The fixed end of the air pump 101 is rigidly fixed to a first fixing block 102. The first fixing block 102 is horizontally fixed to a smooth first fixing post 104 on the side facing the center of the operating table 3. The first fixing post 104 is suspended as a linear guide rail. At the same time, the second fixing block 103 is constructed with a guide hole that precisely matches the outer diameter of the first fixing post 104. In order to improve the smoothness of sliding and positioning accuracy, a linear bearing is embedded in the guide hole or a self-lubricating coating is applied. The second fixing block 103 is slidably fitted onto the first fixing post 104 through the guide hole. The first fixing post 104 restricts all degrees of freedom of the second fixing block 103 except for axial movement.

[0029] To achieve power transmission, a transmission connection is established between the end of the telescopic rod of the air pump 101 and the second fixed block 103 through a connecting plate 105. The connecting plate 105 serves as an intermediate connecting rod, and its two ends are respectively hinged through vertically arranged second fixed posts 106. One second fixed post 106 is rotatably connected to the end of the telescopic rod of the air pump 101, and the other second fixed post 106 is rotatably connected to the second fixed block 103. This double-pin hinge structure allows for a small angular deviation between the telescopic rod of the air pump 101 and the second fixed block 103, thereby smoothly converting the linear telescopic motion of the air pump 101 into a translational motion that pulls the second fixed block 103 to slide along the first fixed post 104.

[0030] An elastic rubber pad 107 is fixedly attached to the inner wall of the second fixing block 103 facing the mold placement area. The contact surface of the rubber pad 107 is pre-made with a grid-like or striped anti-slip texture. When the air pump 101 moves the second fixing block 103 inward, the rubber pad 107 can flexibly clamp the outer wall of the glass mold. While providing sufficient positioning friction, it relies on its own elastic deformation to buffer the clamping impact and prevent hard metal from causing pressure damage to the surface of the glass mold.

[0031] The working principle of this non-contact glass mold cavity volume rapid detection mechanism is as follows: When it is necessary to test the volume of a glass mold, the glass mold to be tested is first placed in the center of the operating table 3. Then, the positioning mechanism 1 is activated. The air pump 101 receives the control signal and starts to work. Its internal cylinder drives the telescopic rod to retract backward. This retraction action causes the connecting plate 105, which is rotatably connected to it, to move. The connecting plate 105 then pulls the second fixing block 103 to slide along the first fixing column 104 towards the mold until the rubber pad 107 on the side wall of the second fixing block 103 is tightly pressed against the outer wall of the glass mold. Relying on the continuous pressure of the air pump 101 and the elastic deformation of the rubber pad 107, the mold is flexibly and firmly clamped and positioned to prevent the mold from shifting in subsequent processes.

[0032] After the mold is stably fixed, the motor 202 inside the base 5 is started. The motor 202 drives the gear 201 to rotate. The gear 201 transmits torque to the operating table 3 through meshing with the teeth on the outer periphery of the operating table 3, causing the operating table 3 to rotate at a constant speed around the central axis determined by the limit post 205. During this process, the rollers 203 evenly distributed on the base 5 continuously roll in the slide groove 4, providing multi-point support for the operating table 3 and limiting its radial and axial sway, ensuring high stability of the rotation process. At the same time, the scanner 7 located above is started, using its tilted field of view to perform a full-range non-contact scan of the rotating mold, collecting point cloud data of the mold cavity and the outside. The system backend processes this data and uses an integral algorithm to accurately calculate the actual volume of the glass mold cavity.

[0033] After the test is completed, the motor 202 stops rotating, the air pump 101 reverses its action to push the telescopic rod out, and pushes the second fixing block 103 away from the mold surface through the connecting plate 105, releasing the clamping state, and the mold can be removed to complete the entire test process.
