[0031] Example 1

[0032] Figures 1 to 4 An embodiment of the glass plate hand-held gripper of this application is illustrated schematically.

[0033] like Figures 1 to 4As shown, this application discloses a handheld glass plate handling fixture, including: a single handle assembly 1 and a connecting assembly 2. The connecting assembly 2 is detachably connected to the single handle assembly 1, and multiple single handle assemblies 1 are connected in parallel. The single handle assembly 1 includes: a connecting rod 11, a handle 12, and a suction mechanism 13. The connecting assembly 2 is detachably connected to the connecting rod 11. The handle 12 is installed on the upper surface of the middle part of the connecting rod 11. The suction mechanism 13 is symmetrically arranged at both ends of the connecting rod 11. The suction mechanism 13 includes: a suction cup body 131, a locking part 132, and a squeezing ball 133 connected sequentially from bottom to top. The suction cup body 131 is sealed and connected to the squeezing ball 133 through the locking part 132, and the locking part 132 is fixedly connected to the connecting rod 11.

[0034] Through the above structural design, this application uses connecting components 2 to connect multiple single handle components 1, increasing the number of adsorption mechanisms 13 and improving the overall suction force. Furthermore, the adsorption mechanism 13 of this application includes: a suction cup body 131, a locking part 132, and a squeezing ball 133. The squeezing ball 133 can further expel air to increase the negative pressure intensity within the suction cup body 131, thereby further improving the adsorption force of each single handle component 1. At the same time, the connection structure of this application is simple, with few moving parts, resulting in a low probability of damage and effectively reducing maintenance costs.

[0035] refer to Figure 1 In the illustrated embodiment, two single-handle components 1 are connected in parallel via connecting components 2, doubling the number of adsorption mechanisms 13 and thus increasing the overall adsorption force. Simultaneously, each single-handle component 1 in this application has a suction cup body 131 connected to a compression ball 133, which further compresses and exhausts air, increasing the negative pressure suction of the suction cup body 131. Therefore, each adsorption mechanism 13 also enhances its own adsorption force. Thus, this embodiment can meet the needs of handling glass plates of different sizes, especially large-sized glass plates, preventing them from falling and being damaged due to insufficient suction during handling, thereby significantly improving the safety and production efficiency of glass plate handling. Of course, it is understood that the single-handle components 1 of this application can also be used independently to meet the needs of handling small-sized ordinary glass plates.

[0036] In some embodiments of this application, such as Figures 1 to 4As shown, the suction cup body 131, the extrusion ball 133, and the locking part 132 are insert injection molded structures. The suction cup body 131 and the extrusion ball 133 are made of the same material, and their elasticity allows for compression. In addition to being made of the same injection molded material, the locking part 132 also includes a metal threaded insert 1321. The metal threaded insert 1321 serves to strengthen the fixation and provide a rigid connection. The connecting rod 11 has a threaded mounting hole, through which the extrusion ball 133 can be compressed. Thus, the locking part 132 and the mounting hole are threadedly connected to fix the entire adsorption mechanism. Therefore, the adsorption mechanism of this application uses a threaded connection, which is simple to operate, easy to replace, and has a simplified structure with no complex moving parts, resulting in a low damage rate and significantly reducing the production cost and maintenance cost of the tooling.

[0037] Insert molding refers to the process of inserting a pre-prepared insert of a different material into a mold and then injecting injection plastic, allowing the injection plastic to cool and solidify with the insert to form a single, integrated product. In this application, after the suction cup body 131, locking part 132, and extrusion ball 133 are injection molded, the threaded insert 1321 is partially embedded within the cooled and solidified injection plastic, with its threaded portion exposed to mate with the mounting hole of the connecting rod 11 for threaded connection. This allows for quick and convenient installation and replacement of the suction mechanism 13. Furthermore, compared to the complex movable vacuum chamber structure of existing technologies, this application simplifies the tooling complexity, eliminating the need for numerous movable parts. It allows for rapid and repeated manufacturing with only one mold opening, resulting in low manufacturing and maintenance costs, thereby effectively controlling the production cost of the glass plate.

[0038] In some embodiments of this application, such as Figure 4 As shown, the suction cup body 131 includes a suction cup bowl 1311, the lower end face of which is larger than the upper end face, thereby forming an adsorption cavity for contacting the glass plate (i.e., Figure 4 As shown in Figure 1a). A connecting cavity 1b is provided above the suction cavity 1a, and the connecting cavity 1b is in continuous communication with the locking part 132 (i.e., the inner cavity 2a of the locking part 132). Furthermore, the outer surface profile of the suction cup body 131 has an inverted trapezoidal cross-section. A certain thickness of injection-molded material is formed between the outer surface profile of the suction cup body 131 and the connecting cavity 1b, which helps maintain the shape stability of the connecting cavity and increases the structural strength of the suction cup body 131. Simultaneously, this support structure also maintains the spatial gap between the connecting rod 11 and the glass plate, preventing the worker's gloves or the fixing bolts 3 below the connecting rod 11 from scratching the glass during handling.

[0039] In some embodiments of this application, such as Figures 1 to 4As shown, the extrusion ball 133 is a regular sphere and is provided with vacuum-breaking protrusions 1331. These vacuum-breaking protrusions 1331 are also known as "vacuum-breaking protrusions." They are evenly distributed on the inner wall of the extrusion ball 133, maintaining micropores between the inner walls to allow air to flow in and facilitate the extrusion ball 133's smooth recovery of its shape. This prevents the extrusion ball 133 from sticking together and becoming difficult to separate due to aging or moisture absorption. Figure 4 As shown, the inner cavity 3a of the squeezing ball 133 is connected to the inner cavity 2a of the locking part 132, so that when the suction cup body 131 exhausts and adsorbs, the volume of the air discharged can be increased by squeezing, thereby further increasing the negative pressure in the suction cup body 131, increasing the adsorption force of the suction cup body 131, and ensuring that large-sized glass plates will not fall and be damaged.

[0040] In some embodiments of this application, such as Figure 3 As shown, the total injection molding length L1 of the locking part 132 is greater than the thickness D of the connecting rod 11, thus allowing for a certain thread adjustment margin. This ensures that the height of each suction cup 131 in the connected single handle assembly 1 is adjusted consistently, improving the flatness of the suction cup 131 to guarantee a balanced adsorption effect. The threaded insert 1321 is located on the lower outer side of the locking part 132 and has external threads that mate with the connecting rod 11. The length of the external thread of the threaded insert 1321 is less than the thickness of the connecting rod 11, providing a longer injection molding material buffer between the upper end of the threaded insert 1321 and the extrusion ball 133. This prevents cracking at the threaded insert 1321 caused by repeated extrusion from the extrusion ball 133, and also reduces the extrusion resistance of the extrusion ball 133, facilitating operation and venting.

[0041] In some embodiments of this application, the adsorption mechanism 13 is injection molded using inserts made of fluororubber. Fluororubber has good shape retention and is durable, ensuring a long service life for the adsorption mechanism 13. Specifically, the suction cup body 131 and the extrusion ball 133 are both made of a single type of fluororubber, while the locking part 132 includes threaded inserts made of both fluororubber and metal.

[0042] In some embodiments of this application, the single handle assembly 1 is divided into multiple groups with different rules. In different groups of single handle assemblies 1, the length of the connecting rod 11 is different, so that it can be used to match glass plates of different sizes and shapes.

[0043] In some embodiments of this application, each end of the connecting rod 11 of the single handle assembly 1 is provided with one or more suction mechanisms 13, specifically determined according to the weight specifications of the glass plate being transported. For example, in this application Figures 1 to 4In the illustrated embodiment, each end of the connecting rod 11 is provided with an adsorption mechanism 13. In other embodiments, each end of the connecting rod 11 may be provided with multiple adsorption mechanisms 13 to further improve the suction force.

[0044] In some embodiments of this application, such as Figure 1 and Figure 2 The single handle assembly 1 has a connecting rod 11 with a connecting through hole. The connecting assembly 2 includes a connecting plate 21 with a cross-section matching the connecting through hole. After the connecting plate 21 passes through the connecting through hole, it is fixedly connected to the connecting rod 11 by fixing bolts 3. Understandably, the connecting plate 21 has corresponding positioning holes. After passing through the connecting through hole, the fixing bolts 3 are screwed into the positioning holes to fix the connecting plate 21 to the connecting rod 11. In this embodiment, multiple fixing bolts 3 are provided along the length of the connecting plate 21.

[0045] In some embodiments of this application, such as Figures 1 to 4 As shown, the handle 12 of the single handle assembly 1 is horizontally positioned, parallel to the connecting plate 21 and thus parallel to the glass plate.

[0046] Example 2

[0047] Unlike Embodiment 1, in this application Figure 5 In the second embodiment shown, the handle 12 of the single handle assembly 1 is tilted at a predetermined angle. Tiltd handling of the handle 12 of the single handle assembly 1 makes it more suitable for hand-carrying large glass plates. When a person carries a large glass plate by hand, the hand is at an angle away from the body. In the case of the horizontal handle in the first embodiment, the direction of force can cause the glass plate to tilt too much, easily leading to weight shift and slippage. However, in the second embodiment of this application, the tilted handle 12 better adapts to the angle of force exerted by the human arm, thus keeping the large glass plate relatively horizontal, improving handling safety, preventing the glass plate from falling and being damaged, and improving production efficiency.

[0048] In summary, the glass plate handheld gripping fixture of this application includes: a single handle assembly 1 and a connecting assembly 2; the connecting assembly 2 is detachably connected to the single handle assembly 1, and multiple single handle assemblies 1 are connected in parallel; the single handle assembly 1 includes: a connecting rod 11, a handle 12, and a suction mechanism 13; the connecting assembly 2 is detachably connected to the connecting rod 11; the handle 12 is installed on the upper surface of the middle part of the connecting rod 11; the suction mechanism 13 is symmetrically arranged at both ends of the connecting rod 11; the suction mechanism 13 includes: a suction cup body 131, a locking part 132, and a squeezing ball 133 connected sequentially from bottom to top, the suction cup body 131 is sealed and connected to the squeezing ball 133 through the locking part 132, and the locking part 132 is fixedly connected to the connecting rod 11. This application uses the connecting assembly 2 to connect multiple single handle assemblies 1, increasing the number of suction mechanisms 13 and improving the overall suction force. Furthermore, the adsorption mechanism 13 of this application includes a suction cup body 131, a locking part 132, and a squeezing ball 133. The squeezing ball 133 can further expel air to increase the negative pressure intensity within the suction cup body 131, thereby further improving the adsorption force of each single handle assembly 1. At the same time, the connection structure of this application is simple, with few moving parts, resulting in a low probability of damage and effectively reducing maintenance costs.
