Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass processing, in particular to a hole taking equipment for tempered glass. BACKGROUND

[0002] In the field of tempered glass processing, the hole opening process is a key technology, and its quality directly affects the performance of products in high-end application scenarios such as building curtain walls, electronic device panels, and automobile glass. Due to the special stress structure of tempered glass, the high-pressure stress layer on the surface makes traditional mechanical processing methods face serious challenges. Mechanical drilling or stamping process often causes edge cracking, uneven stress release, and even the whole glass to crack and fail, which requires the development of more precise and controllable hole taking technology. The method of laser cutting combined with cooling separation commonly used in the industry solves the defects of traditional processes to some extent, but there are still many technical bottlenecks in actual application. In the cooling separation process, the cutting area is cooled and static pressure is applied by the cooling pressure plate. The balance of this process parameter is particularly critical. If the pressure is too small, the cutting disc cannot form a complete fracture surface around the edge, and the residual connection point not only affects the hole quality, but also requires subsequent secondary processing. If the pressure is too large, it may cause sudden fracture when the glass is in a cold brittle state, causing edge cracking defects or uncontrollable crack propagation, which seriously affects the mechanical strength and aesthetics of the product.

DETAILED DESCRIPTION

[0026] To further understand the features, technical means and specific purposes and functions achieved by the present application, the present application is described in further detail below in conjunction with the drawings and specific embodiments.

[0027] As Figure 1 , Figure 2 and Figure 3As shown, a hole taking device for toughened glass is used to take off the disc formed by hot cutting on the glass, comprising a fixed frame 1 arranged on the top of the toughened glass, a driving frame 2 arranged on the bottom of the fixed frame 1 in a lifting manner, a lifting driving assembly 3 arranged on the fixed frame 1 and in transmission connection with the driving frame 2, a driven frame 4 arranged below the driving frame 2, and an elastic buffer assembly 5 arranged between the driving frame 2 and the driven frame 4, a vibrating piece 6 arranged on the driven frame 4 and capable of moving in a longitudinal reciprocating manner, and a vibrating driving assembly 7 connecting the driving frame 2 and the vibrating piece 6, when the driving frame 2 generates displacement relative to the driven frame 4, the vibrating piece 6 moves in a longitudinal reciprocating manner, and a cooling disc 8 arranged at the bottom end of the driven frame 4 and corresponding to the position of the hot cutting disc, in a working state, the cooling disc 8 is pressed on the disc and exerts a separating force.

[0028] A counterweight bolt 62 is arranged on the vibrating piece 6 and threadedly connected with the vibrating piece 6, and the inertia force of the vibrating piece 6 is adjusted by adjusting the number of the counterweight bolts 62. When the toughened glass is subjected to hot cutting (such as laser cutting or other thermal cutting), the disc is still connected with the toughened glass, and the cutting position is high temperature, after cooling, the disc can be separated from the toughened glass, so as to realize the hole taking operation.

[0029] The present application is used for disc separation operation of the toughened glass subjected to hot cutting treatment. The device mainly comprises a fixed frame 1, a driving frame 2, a driven frame 4 and a matching driving system. The fixed frame 1 is installed above the toughened glass as a main supporting structure, and the bottom thereof is provided with the driving frame 2 capable of lifting, and the lifting driving assembly 3 is used to realize accurate vertical displacement control. The driven frame 4 arranged below the driving frame 2 is flexibly connected with the driving frame 2 through the elastic buffer assembly 5, and this structure design not only guarantees the stability of transmission, but also can effectively absorb mechanical impact in the operation process.

[0030] The vibrating piece 6 capable of moving in a longitudinal reciprocating manner is arranged in the driven frame 4, and the vibrating driving assembly 7 specially designed is linked with the driving frame 2. When the device works, the relative displacement between the driving frame 2 and the driven frame 4 is converted into regular reciprocating motion of the vibrating piece 6. This motion is transmitted to the disc area to be separated through the cooling disc 8, so that the micro cracks formed by hot cutting can be uniformly expanded along the predetermined path. The cooling disc 8 is installed at the bottom end of the driven frame 4 and is accurately positioned with the disc formed by hot cutting, and in the operation, the disc is subjected to controllable separating force.

[0031] To further optimize the vibration effect, an adjustable counterweight system is specially designed on the vibration member 6. By increasing or decreasing the number of threaded connecting counterweight bolts 62, the inertia parameters of the vibration member 6 can be accurately adjusted to adapt to the processing requirements of tempered glass of different thicknesses and materials. The working principle of the device is based on temperature control separation after hot cutting. After the laser or other heat source completes the disc cutting, the cutting part in a high-temperature state is rapidly cooled under the action of the cooling press 8, and the vibration effect is accurately controlled to realize the clean separation of the disc and the glass substrate. This combined separation method effectively avoids the edge defects caused by traditional mechanical separation, significantly improves the hole taking quality and processing efficiency.

[0032] As shown in Figure 4 , Figure 8 and Figure 9 , the vibration member 6 is provided with a circumferential surface with a wavy ring groove 61; the vibration driving assembly 7 includes a rotating column 71 rotatably arranged in the driven frame 4 and coaxial with the circumferential surface; a guide pin 72 is arranged radially on the rotating column 71 and is in sliding fit with the wavy ring groove 61; a linear and rotary converter is connected between the driving frame 2 and the rotating column 71, which is used to convert the linear displacement of the driving frame 2 into the rotary motion of the driving shaft, so that the guide pin 72 slides along the wavy ring groove 61 and drives the vibration member 6 to make longitudinal reciprocating motion.

[0033] When the driving frame 2 is displaced relative to the driven frame 4, the rotating column 71 is driven to rotate through the linear-rotary conversion mechanism.

[0034] The outer circumferential surface of the vibration member 6 is processed with a wavy ring groove 61, and this profile design provides a motion trajectory for vibration transmission. The vibration driving assembly 7 matched therewith adopts a sliding fit mechanism of the rotating column 71 and the guide pin 72, and the rotating column 71 is installed in the driven frame 4 through bearings to ensure smooth rotation. The guide pin 72 is arranged radially along the rotating column 71, and the end thereof is in fit with the wavy ring groove 61 to convert the rotary motion into accurate linear reciprocation.

[0035] The linear-rotary converter converts the vertical displacement of the driving frame 2 into the rotary motion of the rotating column 71. When the lifting driving assembly 3 moves the driving frame 2, the rotating column 71 produces a corresponding change in rotation angle through this conversion structure. With the rotation of the rotating column 71, the guide pin 72 fixed thereon slides along the wavy ring groove 61 of the vibration member 6. Due to the special wave design of the ring groove, this sliding naturally converts into the periodic reciprocating displacement of the vibration member 6 in the longitudinal direction.

[0036] This mechanical vibration generating mechanism has multiple advantages: first, the profile of the wave-shaped ring groove 61 can be precisely designed to achieve precise control of the vibration amplitude and frequency; second, the purely mechanical transmission method avoids the interference and energy consumption problems that may be caused by electromagnetic vibrators; third, this structure has high reliability and stability and can adapt to long-term continuous operation in industrial environments.

[0037] As shown in Figure 6 and Figure 7 , the linear-to-rotary converter includes a gear 731 coaxially fixed to the top end of the rotary column 71, a rack 732 slidingly arranged on the driven frame 4, the rack 732 being engaged with the gear 731, and a connecting rod 733 having two ends respectively rotatably connected with the driving frame 2 and the rack 732 and being in an inclined state. When the driving frame 2 produces displacement relative to the driven frame 4, the rack 732 is driven to slide horizontally by the connecting rod 733, thereby driving the gear 731 and the rotary column 71 to rotate.

[0038] When the lifting drive assembly 3 drives the driving frame 2 to produce vertical displacement, the inclined connecting rod 733 decomposes this linear motion into a horizontal component, pushing the rack 732 to slide. The engagement transmission between the rack 732 and the gear 731 converts the horizontal linear motion into the circular motion of the rotary column 71. Due to the inherent accuracy of the gear 731-rack 732 transmission, the rotation angle of the rotary column 71 and the displacement amount of the driving frame 2 maintain a strict linear relationship, thereby ensuring the precise controllability of the reciprocating motion of the vibration piece 6. By changing the inclination angle of the connecting rod 733 or the transmission ratio of the gear 731-rack 732, the motion conversion parameters can also be flexibly adjusted to meet the vibration requirements under different process conditions.

[0039] As shown in Figure 7 , the linear-to-rotary motion converter further includes a guide rod 734 arranged horizontally on the top of the driven frame 4, both ends of the guide rod 734 being fixedly connected with limit seats 735, and a guide hole being formed in the rack 732 and coaxially matched with the guide rod 734, so that the rack 732 can slide along the length direction of the guide rod 734.

[0040] The guide rod 734 is firmly fixed at both ends by the limit seats 735 on the top of the driven frame 4, forming a stable support frame. The rack 732 body is machined with a high-precision guide hole, which forms a precise sliding fit with the guide rod 734. This fit ensures that the rack 732 always maintains an ideal horizontal trajectory during movement.

[0041] The limiting seat 735 at both ends of the guide rod 734 not only plays a fixing role, but also can effectively absorb the impact energy when the rack 732 moves to the limit position. A self-lubricating bushing can be arranged in the guide hole to significantly reduce the friction coefficient and prolong the service life. This guide structure completely avoids the phenomena of deflection and jamming during the reciprocating motion of the rack 732, ensuring the stability of the meshing of the gear 731 and the rack 732.

[0042] As shown in Figure 8 A fixed rod 41 is arranged in the driven frame 4, the fixed rod 41 is arranged in the driven frame 4 along the circumference of the rotating column 71, the fixed rod 41 extends longitudinally, and a guide sliding hole is opened on the vibration piece 6, the guide sliding hole is coaxially matched with the fixed rod 41, so that the vibration piece 6 can move reciprocatingly along the longitudinal direction.

[0043] The longitudinal arrangement of the fixed rod 41 not only provides a guide function, but also enhances the overall rigidity of the driven frame 4. A composite material bushing with low friction coefficient can be arranged in the guide sliding hole, which not only ensures smooth movement, but also avoids wear caused by direct metal contact. The symmetrical distribution of multiple fixed rods 41 effectively prevents the deflection or jamming phenomenon that may occur when the vibration piece 6 moves at high speed. The cooperation of the guide system and the wave-shaped ring groove 61 transmission mechanism ensures efficient transmission of vibration energy in the predetermined direction, without unnecessary energy loss.

[0044] As shown in Figure 8 The fixed rod 41 is sleeved with an upper elastic element 42 and a lower elastic element 43, the upper elastic element 42 and the lower elastic element 43 are located at the top and bottom of the vibration piece 6 respectively, and the upper elastic element 42 and the lower elastic element 43 jointly constitute an elastic support structure of the vibration piece 6.

[0045] The fixed rod 41 is sequentially sleeved with the upper elastic element 42 and the lower elastic element 43, and the two are located at the upper end and the lower end of the vibration piece 6 respectively. When the vibration piece 6 is displaced, whether it moves upward or downward, the elastic element at the corresponding position can effectively transmit the vibration force generated by the vibration piece 6 to the driven frame 4. Specifically, when the vibration piece 6 moves upward, the upper elastic element 42 is deformed under pressure, and the stored elastic energy acts on the driven frame 4; when the vibration piece 6 moves downward, the lower elastic element 43 is deformed under compression, and also transmits vibration force to the driven frame 4 through elastic restoring force.

[0046] This structure not only ensures that the vibration can be transmitted to the driven frame 4 in bidirectional movement, but also helps to realize more stable and continuous vibration output through the buffering and resetting functions of the upper elastic element 42 and the lower elastic element 43. The driven frame 4 driven by this structure drives the cooling pressure plate 8 to vibrate, so that the disc is separated from the glass body.

[0047] As shown in Figure 8As shown, the driven frame 4 includes an upper frame body 44 and a lower frame body 45, the fixing rod 41 and the vibrating member 6 are arranged between the upper frame body 44 and the lower frame body 45, the cooling pressure plate 8 is arranged at the bottom of the lower frame body 45, and the elastic buffer assembly 5 is arranged between the active frame 2 and the upper frame body 44.

[0048] The driven frame 4 is an integrated structure consisting of an upper frame body 44 and a lower frame body 45, which are connected to the vibrator 6 via a fixing rod 41, forming an internal support frame with good guidance and rigidity. The vibrator 6 is arranged in the core area between the fixing rods 41, and can vibrate freely in the longitudinal space while maintaining structural stability. The lower frame body 45 serves as a mounting platform for the cooling platen 8, and a cooling platen 8 is provided at the bottom thereof to ensure that the vibration energy can be efficiently transmitted to the interface area in contact with the glass. An elastic buffer component 5 is arranged between the active frame 2 and the upper frame body 44 to form a flexible transition area, so that the movement generated by the active frame 2 under vertical drive can be transmitted to the driven frame 4 system through controlled buffering deformation, further stimulating the high-frequency response of the internal vibrator 6.

[0049] This structural arrangement not only improves the dynamic contact accuracy between the cooling platen 8 and the glass, but also ensures the consistency of the vibration direction through the fixing rod 41, thereby reducing energy loss and mechanical interference.

[0050] like Figure 2 As shown, the elastic buffer assembly 5 includes connecting rods 51, which are arranged in a rectangular array at the top of the upper frame 44. The connecting rods 51 extend upward and slide through the drive frame. A limit ring 52 is provided at the top of the connecting rod 51; an upper buffer element 53 is sleeved on the connecting rod 51, and the upper buffer element 53 is located between the limit ring 52 and the active frame 2; and a lower buffer element 54 is sleeved on the connecting rod 51, and the lower buffer element 54 is located between the drive frame and the upper frame 44.

[0051] The elastic buffer assembly 5 consists of multiple connecting rods 51, upper and lower buffer elements 54, and a limit structure. These are arranged in a rectangular array atop the upper frame 44, forming a symmetrical and uniform force distribution network. Each connecting rod 51 extends upward from the upper frame 44, sliding through the active frame 2. A limit ring 52 is located at its top. This limit ring 52 acts as a mechanical constraint, limiting the maximum vertical travel of the connecting rod 51 and preventing structural damage to the buffer device due to overload.

[0052] An upper buffer element 53 and a lower buffer element 54 are mounted on the connecting rod 51, located between the retaining ring 52 and the drive frame, and between the drive frame and the upper frame 44, respectively, forming a bidirectional elastic damping system. The upper buffer element 53 primarily provides a reaction force when the active frame 2 is pressed downward, preventing direct impact and absorbing some of the initial impact energy. The lower buffer element 54 absorbs residual kinetic energy during the system's rebound or upward movement, ensuring a smooth transition throughout the entire vibration and loading process.

[0053] As Figure 2 shown, the lifting drive assembly 3 includes a servo motor 31 arranged on the fixed frame 1, a lead screw 32 coaxially connected with the output shaft of the servo motor 31, and the bottom end of the lead screw 32 penetrates the driving frame 2 and is threadedly connected therewith.

[0054] The servo motor 31 is fixedly installed on the rigid fixed frame 1 of the device, and is coaxially connected with the lead screw 32 through the output shaft, thereby ensuring the coaxiality and stability of power transmission. The lower end of the lead screw 32 penetrates the main body of the driving frame 2 and is connected therewith through a threaded structure, forming a controllable vertical lifting mechanism.

[0055] The servo motor 31 can rotate accurately according to the working program set by the system, thereby driving the lead screw 32 to rotate and realize the linear lifting movement of the driving frame 2. This driving form has the advantages of fast response speed, high positioning accuracy and stable operation, and is especially suitable for precise machining scenes requiring high-frequency start-stop and micro-displacement adjustment.

[0056] Through the threaded connection structure, the rotary motion of the lead screw 32 is efficiently converted into the vertical displacement of the driving frame 2, thereby driving the driven frame 4 system arranged below to produce relative motion. Cooperating with the bidirectional elastic adjustment mechanism of the elastic buffer assembly 5, this lifting driving mode not only can dynamically regulate the contact pressure, but also can provide stable mechanical feedback during the movement process, thereby providing necessary initial displacement and load conditions for the excitation and energy transmission of the subsequent vibration system.

[0057] As Figure 5 and Figure 10 shown, it also includes a bracket 9 arranged at the bottom of the hot cutting disc, the bracket 9 is provided with a receiving groove corresponding to the disc, and a cooling tray 91 is arranged in the receiving groove, the top end of the cooling tray 91 is flush with the bracket 9, and an elastic pushing element 92 is arranged between the cooling tray 91 and the bottom end of the receiving groove. When the cooling pressure plate 8 presses the hot cutting disc into the receiving groove, the bracket 9 moves downward and drives the cooling tray 91 to push the disc out of the receiving groove through the elastic pushing element 92.

[0058] The bracket 9 assembly is installed below the hot cutting disc, and is mainly used for dynamically supporting and cooling the bottom of the glass disc. The bracket 9 is internally provided with a receiving groove corresponding to the outer shape of the disc, which is used to stably receive the falling disc after the cooling pressure plate 8 is pressed away from the glass disc, so as to avoid direct contact with the bottom hard structure and cause damage or stress accumulation.

[0059] The tray 9 is embedded with an integrated cooling tray 91, whose top surface is flush with the upper surface of the tray 9, for receiving the disc and preliminarily dissipating heat. Below the cooling tray 91 is an elastic pushing element 92, such as a spring or rubber column, which is compressed and stores energy when the tray 9 is moved downward as a whole.

[0060] In the working process, after the cooling press disc 8 completes the hot-press cutting of the glass disc, the disc is released back into the receiving groove of the tray 9, and the tray 9 is driven to move downward by the vertically arranged air cylinder. At this time, the elastic pushing element 92 is compressed. When the disc is stably dropped into the receiving groove, the elastic pushing element 92 automatically releases the stored energy, and the cooling tray 91 is lifted to slowly push the disc out of the groove, so that the disc is convenient for subsequent taking out or transmission, and at the same time, the disc is also prepared for the arrival and cooling of the next glass disc.

[0061] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
