Abstract
Description
Technical Field
[0001] This invention relates to the field of glass processing technology, and in particular to a glass bending and tempering preparation equipment and its application method. Background Technology
[0002] In the glass bending and tempering process, the raw glass sheet needs to undergo multiple pre-treatment processes such as cutting, edge grinding, cleaning, and coating. It is also transferred between various workstations via intelligent suspended conveyor equipment to ultimately form a tempered glass substrate that meets the dimensional and optical performance requirements. These processes are usually distributed across different functional workstations, and the raw glass sheet needs to be transferred between these workstations efficiently, cleanly, and without damage.
[0003] Glass conveying and hanging structures are mainly divided into two categories: flexible rope type and rigid bracket type. The former is prone to large swings during the conveying process due to the lack of rigid restraint, and is easily damaged by collisions with objects near the conveying path, resulting in poor stability. The latter's suction cups lack buffering and self-adaptive capabilities when in contact with the glass, and are prone to damage such as glass chipping and indentation due to rigid impacts or local stress concentrations, making it difficult to meet the dual requirements of smooth contact and rigid and stable conveying. Therefore, existing glass conveying and hanging structures cannot simultaneously achieve smooth contact during loading and unloading and stable operation during conveying. Summary of the Invention
[0004] In view of this, the present invention proposes a glass bending and tempering preparation equipment and its application method. By integrating multiple universal ball joints in the boom and utilizing a vacuum channel shared with the suction cup, the annular diaphragm is driven to fit the V-shaped groove on the ball head while adsorbing the glass under negative pressure, so as to achieve automatic joint locking. This allows the boom to remain flexible when in contact with the glass to adapt to the surface and to become rigid during the conveying process to suppress swaying. This solves the technical problems of existing intelligent suspended conveying systems, such as flexible suspension being prone to swinging, rigid supports being prone to damaging the glass, and difficulty in balancing the safety of picking and placing and the stability of conveying.
[0005] The technical solution of this invention is implemented as follows: On one hand, the present invention provides a glass bending and tempering preparation device, including a chain conveyor, a boom, and a suction cup, wherein, The upper end of the boom is vertically connected to the conveyor chain of the ring chain conveyor via a pneumatic linear slide, and the lower end is connected to the suction cup to form a suspended glass conveying mechanism. The boom is composed of multiple universal ball joints connected in series. Each universal ball joint includes a ball head and a ball groove that are rotatably engaged. A sealing element is provided between the groove opening and the ball head. The outer wall of the ball head has a first annular groove with a V-shaped cross section along the circumferential direction. The inner wall of the ball groove has an annular diaphragm along the circumferential direction. The boom has an air passage inside, which connects the suction cup and the first annular groove. When there is negative pressure in the air passage, the annular diaphragm elastically deforms and fits towards the first annular groove, thereby restricting the relative rotation between the ball head and the ball groove.
[0006] Based on the above technical solution, preferably, the inner wall of the ball groove is provided with a second annular groove along the circumference, and the side of the ball groove is provided with a ventilation hole communicating with the second annular groove in a radial direction. The edge of the annular diaphragm is fixed to the groove wall of the second annular groove, and the middle part is suspended to form a tympanic membrane structure; In its natural state, the annular diaphragm is located in the second annular groove and has a clearance gap with the ball head.
[0007] Based on the above technical solutions, preferably, a filter screen is embedded in the ventilation hole.
[0008] Based on the above technical solutions, preferably, the inner wall of the first annular groove is provided with multiple V-shaped grooves, and the annular diaphragm has multiple hemispherical protrusions on the side near the ball head, wherein, When there is negative pressure in the airway, the protrusion is embedded in the adjacent groove.
[0009] Based on the above technical solutions, preferably, the boom is hollow, and a lifting rope is threaded through and fixed inside it. The suspension rope is fitted with a sleeve, and the sleeve is equipped with a vacuum equipment connecting pipe, an annular groove connecting pipe and a suction cup connecting pipe.
[0010] Based on the above technical solutions, preferably, an airflow channel is formed between the jacket and the suspension rope, and the airflow channel constitutes part of the air passage.
[0011] Based on the above technical solutions, preferably, the upper end of the lifting rope is fixedly connected to the ball head at the top of the boom, and the lower end is fixedly connected to the ball groove at the bottom of the boom.
[0012] Based on the above technical solutions, preferably, the suction cup is provided with a connecting cylinder at its top, wherein... The lower end of the ball groove at the bottom of the boom is screwed into the connecting cylinder by a sealing thread.
[0013] Based on the above technical solutions, preferably, the pneumatic linear slide is fixed vertically on the conveyor chain of the chain conveyor, its output end is fixedly connected to the ball head at the top of the boom through a flange, and the side of the pneumatic linear slide is slidably engaged with the outer peripheral surface of the chain conveyor.
[0014] On the other hand, the present invention also provides a method for applying a glass bending and tempering preparation equipment, which includes the following steps: S1. The boom is moved above the glass by the chain conveyor. S2. The suction cup is driven to descend and contact the glass surface by the pneumatic linear slide. Then, a vacuum is drawn to form a negative pressure in the air channel. The suction cup adsorbs and fixes the glass. At the same time, the annular diaphragm elastically deforms and fits in the direction of the first annular groove, so that the ball head is fixed relative to the ball groove. S3. Maintain a vacuum state and transport the glass to the target station via the chain conveyor.
[0015] The glass bending and tempering preparation equipment and its application method of the present invention have the following advantages over the prior art: (1) By designing the boom as a series of multiple universal ball joints and using the air channel shared with the suction cup to drive the annular diaphragm to fit the V-shaped first annular groove on the ball head under negative pressure, the boom can remain flexible in non-working state to adapt to the glass surface contour, achieve impact-free picking and placing, and automatically transform into a rigid structure after adsorption to effectively suppress the swaying during the conveying process, thus taking into account both contact compliance and running stability.
[0016] (2) By designing the cross-section of the first annular groove as V-shaped, a turning surface with guiding and limiting functions is formed on the outer wall of the ball head, so that the annular diaphragm can be more reliably attached and embedded under negative pressure, thereby improving its locking stability. At the same time, multiple V-shaped grooves are further set in the V-shaped annular groove, and hemispherical protrusions are arranged on the side of the annular diaphragm facing the ball head. When the negative pressure is established, the protrusions are precisely embedded in the grooves, forming a multi-point mechanical interlocking structure, which enhances the torsional stiffness of the joint and further improves the accuracy of maintaining the glass posture during the conveying process.
[0017] (3) By setting a second annular groove on the inner wall of the ball groove and fixing the edge of the annular diaphragm to form a diaphragm structure, while retaining the clearance between it and the ball head, it is ensured that the diaphragm is completely retracted into the groove in the natural state without interference, so that the universal joint structure can rotate freely and ensure the omnidirectional adaptability when picking up and putting down.
[0018] (4) By inserting a jacketed hoisting rope inside the hollow boom and integrating multiple connecting pipes on the jacket, the vacuum, annular groove and suction cup air paths are centrally led out, simplifying the external pipeline layout and improving the utilization rate of the internal space of the boom and the neatness of the system. At the same time, an airflow channel is formed between the hoisting rope and the jacket, which, as part of the air passage, makes the gas transmission path closed and stable, reduces the risk of leakage, and ensures the efficiency of negative pressure transmission and the locking response speed.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention.

[0027] like Figure 1-8 As shown, a glass bending and tempering preparation device of the present invention includes a chain conveyor 1, a boom 2, a suction cup 3, and a pneumatic linear slide 4.
[0028] The ring chain conveyor 1 is used to achieve continuous and cyclical material transport in the glass bending and tempering production line. Its main structure includes a ring conveyor chain that runs cyclically along a closed track and is driven by a motor-driven sprocket. The conveyor chain of the ring chain conveyor 1 is provided with downwardly extending Z-shaped rigid hanging brackets at intervals. One end of each hanging bracket is fixed to a specific link or accessory of the chain (not shown in the illustration) by bolts, while the other end extends downwards to mount the pneumatic linear slide 4.
[0029] The upper end of the boom 2 is vertically mounted on the conveyor chain of the chain conveyor 1 via a pneumatic linear slide 4, and the lower end is connected to a suction cup 3 to form a suspended glass conveying mechanism. In this conveying structure, the boom 2 moves with the chain and automatically transfers glass between various process stations (such as cutting, edging, cleaning, coating, and bending tempered glass inlets) along a preset path.
[0030] Specifically, the boom 2 has a hollow structure, consisting of multiple universal ball joints connected end to end. Each universal ball joint includes a ball head 21 and a ball groove 22 that rotate and engage with each other. A sealing element 24 is provided between the groove opening of the ball groove 22 and the ball head 21 to ensure internal airtightness. The outer wall of the ball head 21 has a first annular groove 2101 with a V-shaped cross-section along its circumference, and an annular diaphragm 23 is provided at a corresponding position on the inner wall of the ball groove 22. The boom 2 has an air passage 201 inside, which connects the suction cup 3 and the first annular groove 2101. When the vacuum system creates a negative pressure by drawing a vacuum, the external atmospheric pressure pushes the annular diaphragm 23 to elastically deform and tightly fit towards the first annular groove 2101, thereby restricting the relative rotation between the ball head 21 and the ball groove 22, transforming the originally flexible universal joint into a rigid connection structure. This design achieves the dual functions of flexible self-adaptation during loading and unloading and rigid anti-sway during transport, effectively solving the technical problems of traditional flexible suspensions being prone to swaying and rigid supports being prone to damaging glass.
[0031] To further enhance locking reliability, the V-shaped cross-section of the first annular groove 2101 forms a distinct turning surface on the surface of the ball head 21, guiding and limiting the annular diaphragm 23, allowing it to be more stably embedded under negative pressure. Simultaneously, multiple V-shaped recesses 2102 are also provided on the inner wall of the first annular groove 2101, and multiple hemispherical protrusions 231 are provided on the side of the annular diaphragm 23 near the ball head 21. When negative pressure is established within the air passage 201, the protrusions 231 are driven by diaphragm deformation to embed into adjacent recesses 2102, forming a multi-point mechanical interlocking structure. This enhances the torsional stiffness and shear resistance of the joint, thereby better maintaining the glass's posture during transport and improving transport stability.
[0032] The multiple grooves 2102 located on the ball head 21 are interconnected circumferentially to improve the vacuuming effect. At the same time, the grooves 2102 of the ball head 21 are always located inside the ball groove 22 to prevent air leakage.
[0033] To ensure sufficient flexibility of the boom 2 in non-working states, a second annular groove 2201 is provided circumferentially on the inner wall of the ball groove 22. The edge of the annular diaphragm 23 is fixed to the groove wall of the second annular groove 2201, with the middle suspended to form a diaphragm structure. A ventilation hole 2202 is provided radially through the side of the ball groove 22, which communicates with the second annular groove 2201 to keep the internal and external air pressure balanced in real time. In the natural state (i.e., without vacuum), the annular diaphragm 23 is completely retracted into the second annular groove 2201, and a clearance is maintained between it and the outer surface of the ball head 21 to avoid any contact interference, ensuring that each universal ball joint can rotate freely and achieving omnidirectional adaptive fitting to the slight undulations or warps of the glass surface.
[0034] Furthermore, the axial width of the second annular groove 2201 is designed to be greater than the axial width of the first annular groove 2101. When the central axis of the ball head 21 forms an angle with the central axis of the ball groove 22, the first annular groove 2101 and the second annular groove 2201 are relatively misaligned. At this time, since the axial width of the second annular groove 2201 is greater than the axial width of the first annular groove 2101, sufficient deformation margin is provided for the annular diaphragm 23, allowing it to bulge outward and fit into the misaligned area of the first annular groove 2101 under negative pressure, thereby ensuring that the universal joint can achieve effective locking even in the deflection posture.
[0035] In this structure, the annular diaphragm 23 is integrally molded from silicone rubber with a Shore hardness of 50A–70A. Its edges are firmly embedded into the groove wall of the second annular groove 2201 by overmolding or mechanical pressing. A diaphragm structure of uniform thickness is formed in the middle, which takes into account both flexible deformation capability and structural durability, thereby reliably realizing the function of free rotation when there is no negative pressure and rigid locking when there is negative pressure.
[0036] In addition, the ventilation port 2202 is equipped with a filter screen 25, which can effectively block workshop dust from entering the second ring groove 2201, prevent impurities from affecting the diaphragm return or damaging the sealing performance, and improve the long-term operational stability of the equipment in a high-dust environment.
[0037] Based on the above structure, a lifting rope 26 is threaded through the hollow interior of the boom 2, and a sleeve 261 is fitted around the outer periphery of the lifting rope 26. The sleeve 261 is hollow inside, forming a closed airflow channel between the lifting rope 26 and the sleeve 261. This airflow channel constitutes part of the air passage 201 and is used to stably transmit negative pressure gas. The sleeve 261 integrates a vacuum equipment connecting pipe 2611, an annular groove connecting pipe 2612, and a suction cup connecting pipe 2613, which are respectively connected to an external vacuum source, the first annular groove 2101 of each ball joint, and the suction cup 3, realizing centralized extraction and management of multiple air paths, greatly simplifying the external pipeline layout, improving the internal space utilization of the boom 2, and enhancing the overall neatness of the machine.
[0038] In the entire boom 2, the uppermost part of the boom 2 has a ball joint 21 structure, the lowermost part has a ball groove 22 structure, and the middle part has an alternating structure of ball joint 21 and ball groove 22. The upper end of the suspension rope 26 is fixedly connected to the ball joint 21 at the top of the boom 2, and the lower end is fixedly connected to the ball groove 22 at the bottom of the boom 2, forming a through tensile load-bearing structure. Without affecting the relative rotation of each universal ball joint, it effectively transmits the gravity load of the glass and enhances the overall tensile strength of the boom 2.
[0039] The annular groove connecting pipe 2612 is provided in multiple parts, and each annular groove connecting pipe 2612 corresponds to the first annular groove 2101 in a joint. A through hole is opened at the bottom of the first annular groove 2101, and a quick connector for air line is screwed into the through hole. The end of the annular groove connecting pipe 2612 away from the jacket 261 is embedded and fixed in the corresponding quick connector.
[0040] like Figure 4 As shown, in the structure of the boom 2, the outer shell of the ball groove 22 of the upper universal ball joint is fixedly connected to the journal of the ball head 21 of the lower universal ball joint, forming a series connection structure. That is, the ball head 21 of each section is inserted into and fixed in the ball groove 22 of the upper section, and its own ball groove 22 is used to accommodate and fix the ball head 21 of the lower section. In this way, the entire boom 2 is connected in series into an integral flexible rod system that can transmit tension.
[0041] This series connection method ensures that the weight of the glass borne by the suspension rope 26 can be transferred to the top step by step through the fixed connection points of each section. At the same time, each pair of unlocked ball heads 21 and ball grooves 22 still retain relative rotational freedom, giving the boom 2 omnidirectional bending capability in its natural state, which can adapt to local unevenness of the glass surface or changes in spatial path. Under negative pressure, the annular diaphragms 23 inside each section synchronously fit into the corresponding first annular groove 2101 and embed into the recess 2102, making all universal joints instantly rigid, and the entire boom 2 becomes a high-rigidity straight rod, effectively suppressing swaying and torsion during the transportation process.
[0042] Based on this, the suction cup 3 is equipped with a connecting cylinder 31 at the top. The lower end of the ball groove 22 at the bottom of the boom 2 is screwed into the connecting cylinder 31 through a sealing thread. This facilitates quick disassembly and maintenance, and ensures airtightness through the threaded sealing structure, preventing vacuum leakage from affecting the adsorption and locking effect.
[0043] Furthermore, the pneumatic linear slide 4 is vertically fixed to the conveyor chain of the chain conveyor 1. Its output end is rigidly connected to the ball head 21 at the top of the boom 2 via a flange, while its side slides against the outer circumferential surface of the chain conveyor 1, ensuring smooth lifting and reliable guidance. Specifically, the outline of the outer circumferential surface of the chain conveyor 1 is the same as the conveying path of the chain, and a track groove is provided on this outer circumferential surface. A roller is provided at one end of the chain pneumatic linear slide 4 near the outer circumferential surface of the chain conveyor 1, and the roller fits into the track groove. When the chain conveyor 1 drives the pneumatic linear slide 4 to move, the roller rolls along the track groove.
[0044] In actual operation, the chain conveyor 1 first drives the boom 2 to move above the glass. Then, the pneumatic linear slide 4 controls the suction cup 3 to slowly descend and gently contact the glass surface. Next, the vacuum system is activated, creating negative pressure in the air passage 201. While the suction cup 3 adsorbs the glass, the annular diaphragm 23 simultaneously adheres to the first annular groove 2101 and embeds into the recess 2102, completing the joint locking. Finally, under pressure-holding conditions, the chain conveyor 1 smoothly transports the glass to the target workstation.
[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
