Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing positioning device technology, and more specifically, to a glass positioning device. Background Technology
[0002] In the manufacturing and application of laser debonding and film peeling integrated machines, the precise positioning and stable clamping of glass substrates are key to achieving efficient and non-destructive processing. As industries such as display panels and semiconductor packaging continue to increase their requirements for process precision and efficiency, traditional positioning devices are gradually showing insufficient adaptability when dealing with ultra-thin and fragile glass materials. In particular, they face severe challenges in balancing high-precision positioning and surface protection, which restricts the further improvement of overall equipment performance.
[0003] On the one hand, in terms of protection, conventional clamping arms are mostly made of metal and contact the glass directly or through hard clamping blocks. Their local pressure is high and lacks effective buffering. When the clamping force is not well controlled or the equipment vibrates slightly, it is very easy to cause micro-scratches or even structural edge chipping on the glass surface in the stress-concentrated corner areas. On the other hand, in terms of adaptability, most fixed positioning devices or devices with limited adjustable ranges are difficult to quickly and accurately adapt to glass substrates of different sizes and specifications. Each time the product is changed, cumbersome mechanical adjustments or replacement of the entire set of clamps are often required. Not only is debugging time-consuming and laborious, affecting the production rhythm, but there is also a risk of inaccurate positioning or uneven clamping force due to human adjustment errors.
[0004] Therefore, existing glass positioning devices need improvement in terms of their protective effect on glass substrates and their adaptability to glass substrates of different sizes. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a glass positioning device, which solves the technical problems of poor protection effect on glass substrates and poor adaptability to glass substrates of different sizes in the prior art.
[0006] The purpose and effectiveness of the glass positioning device of this utility model are achieved by the following specific technical means:
[0007] A glass positioning device includes a three-jaw mechanical clamp body and clamping arms. The top of the three-jaw mechanical clamp body is provided with three sets of movable seats. Each of the three sets of movable seats is provided with a clamping arm on its top. The bottom of each of the three sets of clamping arms is integrally formed with reinforcing ribs. One end of each of the three sets of clamping arms is provided with a clamping block. The top of the three-jaw mechanical clamp body is provided with a pad. The pad is located between the three sets of clamping arms and is in the shape of a "three-pronged" shape. A glass substrate is provided on the top of the pad.
[0008] According to a preferred embodiment, a protective layer is provided on the top of each of the three sets of clamping arms, the top of each of the three sets of protective layers is in contact with the glass substrate, and two sets of first bolts are provided on the top of each of the three sets of protective layers. The bottom of each set of first bolts penetrates the protective layer and the clamping arm and is threadedly connected to the movable seat.
[0009] According to a preferred embodiment, each of the three sets of clamping blocks is provided with two sets of second bolts on one side, and multiple sets of second bolts penetrate the clamping blocks and are threadedly connected to the clamping arms. Each of the three sets of clamping blocks is in contact with the glass substrate on one side.
[0010] According to a preferred embodiment, the protective layer and the clamping block are both made of urethane rubber, and the clamping arm is made of aluminum alloy.
[0011] According to a preferred embodiment, the top of the pad is provided with three sets of third bolts, all of which penetrate the pad and are threadedly connected to the three-jaw mechanical clamp body.
[0012] According to a preferred embodiment, the pad is made of PP material.
[0013] According to a preferred embodiment, one end of each of the three sets of reinforcing ribs abuts against the three sets of movable seats.
[0014] Based on the above aspects, the embodiments of this application achieve the following:
[0015] 1. The protective layer and clamping blocks at the top of the clamping arm are made of urethane. Uric acid is soft, highly elastic, wear-resistant, and does not easily produce debris. It can effectively buffer the clamping force and prevent the hard metal clamping arm from directly contacting or scratching the surface of the high-value glass substrate. This reduces the risk of physical damage to the glass substrate during the positioning process and ensures the yield rate of subsequent laser debonding and film peeling processes. The clamping arm is made of aluminum alloy and is integrally molded with reinforcing ribs. This not only ensures the lightweight of the component but also improves its structural strength and rigidity, ensuring that it does not deform or shift during repetitive clamping actions and extending the service life of the equipment.
[0016] 2. By adopting a mechanical structure in which the three-jaw mechanical clamp body drives the three moving seats to move synchronously, the three clamping arms can open and close synchronously. This allows one set of devices to stably clamp glass substrates of different specifications within a certain size range, which is highly versatile and reduces the frequency and time of changing fixtures. At the same time, the "trident"-shaped PP material pad is located in the center, providing uniform and stable central support for the glass substrate. Together with the three sets of clamping arms, it forms a more stable clamping, effectively preventing the glass from warping or vibrating due to suspension or uneven force, and preventing movement during subsequent high-precision processing.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.
[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] The glass positioning device includes a three-jaw mechanical clamp body 100 and clamping arms 101. The three-jaw mechanical clamp body 100 can be of model HQM-55-P-8G1-NS1(8). The top of the three-jaw mechanical clamp body 100 is provided with three sets of movable seats 102. The movable seats 102 can move linearly along a preset track on the top of the three-jaw mechanical clamp body 100. Each of the three sets of movable seats 102 is provided with a clamping arm 101. It can be understood that the three-jaw mechanical clamp body 100 can drive the three sets of movable seats 102 to move synchronously closer to or further away from the center through an internal drive mechanism, thereby driving the clamping arms 101 to move. The bottom of each of the three sets of clamping arms 101 is integrally formed with reinforcing ribs 103. The setting of reinforcing ribs 103 can enhance the bending resistance of the clamping arms 101 and improve the strength of the clamping arms 101 without increasing the overall weight too much, so that the clamping arms 101 can withstand long-term stress. When using or clamping a heavy glass substrate 106, it is not easy to deform, providing stable support for subsequent high-precision processing operations. Each of the three sets of clamping arms 101 has a clamping block 104 fixed to one end by bolts. The contact surface of the clamping block 104 is adapted to the edge shape of the glass substrate 106. The clamping block 104 is used to clamp the glass substrate 106 and fix the glass substrate 106 circumferentially to prevent the glass substrate 106 from shifting during processing. A pad 105 is provided on the top of the three-jaw mechanical clamp body 100. The pad 105 is located between the three sets of clamping arms 101 and is in the shape of a "trident". Its three support ends correspond to the inner positions of the three sets of clamping arms 101 respectively. The glass substrate 106 is provided on the top of the pad 105, which can work with the clamping arms 101 to provide multi-point support for the bottom of the glass substrate 106 and prevent the glass substrate 106 from bending due to excessive force at a single point.
[0026] The tops of the three sets of clamping arms 101 are all fitted with protective layers 107, covering the entire top surface area where the clamping arms 101 contact the glass substrate 106. The protective layers 107 prevent direct friction between the glass substrate 106 and the clamping arms 101, avoiding scratches, wear, or even breakage on the surface of the glass substrate 106, reducing the probability of damage to the glass substrate 106 during positioning, and improving the reliability of the device. The tops of the three sets of protective layers 107 are in close contact with the glass substrate 106, ensuring that the glass substrate 106 will not wobble locally when clamped. The tops of the three sets of protective layers 107 are all provided with two sets of first bolts 108. The bottoms of the multiple sets of first bolts 108 penetrate the protective layers 107 and the clamping arms 101 and are threadedly connected to the moving seat 102. Through the tightening action of the first bolts 108, the protective layers 107 can be stably fixed to the top of the clamping arms 101, preventing the protective layers 107 from shifting or falling off during use.
[0027] Two sets of second bolts 109 are provided on one side of each of the three sets of clamping blocks 104. Multiple sets of second bolts 109 pass through the clamping blocks 104 and are threadedly connected to the clamping arms 101. Through the connection of the second bolts 109, the clamping blocks 104 and the clamping arms 101 can be detachably fixed. One side of each of the three sets of clamping blocks 104 is in close contact with the edge of the glass substrate 106.
[0028] It should be noted that when the three-jaw mechanical clamp body 100 drives the moving seat 102 to move through the internal gear transmission mechanism, it can drive the clamping block 104 at one end of the clamping arm 101 to move towards the center. The movement speed of the three sets of clamping blocks 104 is consistent, and the three sets of clamping blocks 104 clamp the glass substrate 106 at the same time, which has a circumferential fixing effect on the glass substrate 106, so that the center of the glass substrate 106 coincides with the center of the three-jaw mechanical clamp body 100, which meets the requirements of subsequent processing for center positioning of the glass substrate 106.
[0029] Both the protective layer 107 and the clamping block 104 are made of urethane. Uric acid is soft, highly elastic, wear-resistant, and does not easily produce debris. When in contact with the glass substrate 106, it can effectively buffer the clamping force and prevent the hard clamping arm 101 from directly contacting or scratching the surface of the glass substrate 106. This reduces the risk of physical damage to the glass substrate 106 during the positioning process. The clamping arm 101 is made of aluminum alloy, which reduces the overall weight while ensuring structural strength. The bottom of the clamping arm 101 is provided with reinforcing ribs 103, which further improves the structural strength of the clamping arm 101 and prevents deformation of the clamping arm 101 during use. This avoids the positioning deviation of the glass substrate 106 caused by the deformation of the clamping arm 101, which would affect the accuracy of subsequent processing steps.
[0030] The top of the pad 105 is provided with three sets of third bolts 110. All three sets of third bolts 110 pass through the pad 105 and are threadedly connected to the three-jaw mechanical clamp body 100. By tightening the third bolts 110, the pad 105 can be stably fixed to the top of the three-jaw mechanical clamp body 100, preventing the pad 105 from shifting during the process of supporting the glass substrate 106, and ensuring the stability of the support for the bottom of the glass substrate 106.
[0031] The pad 105 is made of PP material. PP material has good impact resistance and chemical stability. It will not produce corrosive substances when in contact with the glass substrate 106. In addition, the surface of PP material is smooth and will not scratch the bottom of the glass substrate 106. At the same time, PP material is lightweight and will not increase the extra load on the three-jaw mechanical clamp body 100.
[0032] One end of each of the three sets of reinforcing ribs 103 abuts against one of the three sets of movable seats 102. The abutting surfaces of the reinforcing ribs 103 and the movable seats 102 are polished and have a high degree of fit. This abutting method can transfer part of the force borne by the clamping arm 101 to the movable seat 102, reduce the stress on the clamping arm 101 itself, further reduce the probability of deformation of the clamping arm 101, and ensure the structural stability of the clamping arm 101 during long-term use.
[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
