Technical Field

[0001] This utility model relates to the field of glass processing technology, and more specifically, to an automatic clamping component for a glass engraving machine. Background Technology

[0002] A glass engraving machine is a specialized device for engraving, cutting, grinding, and processing glass surfaces. It is commonly used to create intricate glass art pieces and crafts, or for precision glass cutting and engraving operations in industrial settings. Glass engraving machines can process various glass materials, including ordinary glass, tempered glass, and mirrored glass, and are widely used in decoration, advertising, home furnishings, and crafts.

[0003] Existing glass gripping arms typically use an adsorption device to hold the glass in place. However, in actual operation, due to the varying sizes of glass, relying solely on the adsorption device without adjusting the spacing between the grippers according to the glass size can lead to uneven force distribution, causing the glass to fall and damage itself. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic clamping component for a glass engraving machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic clamping assembly for a glass engraving machine, comprising a connecting mechanism, a fixed plate fixedly connected to the bottom of the connecting mechanism, a fixed frame fixedly connected to the middle of the bottom of the fixed plate, a first motor fixedly connected to the front of the fixed frame, a lead screw fixedly connected to the output shaft of the first motor, a movable plate movably sleeved on both the front and back sides of the outer side of the lead screw, a first clamping assembly installed at the bottom of the movable plate, connecting plates fixedly connected to both sides of the bottom of the fixed plate, a fixed guide rail fixedly connected to the bottom of the connecting plate, and a second clamping assembly installed on both sides of the outer side of the fixed guide rail.

[0006] As a preferred technical solution of this utility model, a positioning rod is fixedly connected to the inner side of the fixed frame, the positioning rod is movably sleeved with the moving plate, and a first thread and a second thread are respectively provided on the front and back sides of the outer side of the lead screw.

[0007] As a preferred technical solution of this utility model, the first clamping component includes a first mounting plate fixedly connected to the bottom of the movable plate, a first clamping plate fixedly connected to one end of the bottom of the first mounting plate, a first clamping pad provided on the surface of the first clamping plate, a first cylinder installed at the other end of the bottom of the first mounting plate, and a first vacuum suction cup installed at the bottom of the piston rod of the first cylinder.

[0008] As a preferred embodiment of this invention, the fixed guide rail has meshing teeth on both sides of its top. Positioning grooves are provided on both the front and back sides of the fixed guide rail.

[0009] As a preferred embodiment of the present invention, the second clamping component includes a movable frame movably sleeved on the outside of the fixed guide rail. A second motor is fixedly connected to the front of the movable frame, and a cylindrical gear is fixedly connected to the output shaft of the second motor. The cylindrical gear meshes with a meshing tooth.

[0010] As a preferred embodiment of this utility model, positioning sliders are fixedly connected to both the front and back sides of the inner wall of the movable frame, and the positioning sliders are slidably sleeved with the positioning grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model comprises a lead screw, a moving plate, a first clamping assembly, a fixed guide rail, and a second clamping assembly. During the movement of the first and second clamping assemblies, the first and second vacuum suction cups move synchronously. After the first and second clamping plates clamp the glass, the first cylinder pushes the first vacuum suction cup to adhere to the top surface of the glass, and the second cylinder pushes the second vacuum suction cup to adhere to the top surface of the glass. Through an external negative pressure vacuum mechanism, the first and second vacuum suction cups adsorb and grasp the glass. In summary, by adjusting the distance between the first and second clamping assemblies, it can adapt to glass of various sizes, ensuring uniform force during clamping and adsorption of the glass, and preventing it from falling off and damaging the glass.

[0022] 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.

[0023] like Figures 1 to 6 As shown, this utility model provides an automatic clamping assembly for a glass engraving machine, including a connecting mechanism 1. A fixed plate 101 is fixedly connected to the bottom of the connecting mechanism 1. A fixed frame 102 is fixedly connected to the middle of the bottom of the fixed plate 101. A first motor 103 is fixedly connected to the front of the fixed frame 102. A lead screw 104 is fixedly connected to the output shaft of the first motor 103. A movable plate 105 is movably sleeved on both the front and back sides of the outer side of the lead screw 104. A first clamping assembly 2 is installed at the bottom of the movable plate 105. Connecting plates 106 are fixedly connected to both sides of the bottom of the fixed plate 101. A fixed guide rail 107 is fixedly connected to the bottom of the connecting plate 106. A second clamping assembly 3 is installed on both sides of the outer side of the fixed guide rail 107.

[0024] In this embodiment of the application, the first motor 103 is started to drive the lead screw 104 to rotate. Under the thread thrust of the first thread 141 and the second thread 142, the two moving plates 105 drive the first clamping assembly 2 to move simultaneously toward each other or away from each other, so that the first clamping plate 202 clamps the front and back of glass of different lengths.

[0025] The second motor 302 is started, driving the cylindrical gear 303 to rotate. Under the meshing action of the cylindrical gear 303 and the meshing teeth 171, the movable frame 301 moves horizontally along the outer side of the fixed guide rail 107, so that the second clamping plate 305 can clamp the two sides of the glass, thus enabling the clamping of glass of different widths. Furthermore, during the movement of the first clamping assembly 2 and the second clamping assembly 3, the first vacuum suction cup 205 and the second vacuum suction cup 308 move synchronously, and the first clamping plate 202 and the second clamping plate 305... After the glass is clamped, the first cylinder 204 pushes the first vacuum suction cup 205 to adhere to the surface of the top of the glass, and the second cylinder 307 pushes the second vacuum suction cup 308 to adhere to the surface of the top of the glass. Through the external negative pressure vacuum mechanism, the first vacuum suction cup 205 and the second vacuum suction cup 308 adsorb and grasp the glass. In summary, by adjusting the distance between the first clamping component 2 and the second clamping component 3, it is possible to adapt to glass of various sizes, so that the force is uniform when clamping and adsorbing the glass, and to prevent it from falling off and causing damage to the glass.

[0026] The fixed frame 102 is fixedly connected to the inner side of the positioning rod 121, which is movably sleeved with the moving plate 105. The front and back sides of the outer side of the lead screw 104 are respectively provided with a first thread 141 and a second thread 142. The thread directions of the first thread 141 and the second thread 142 are opposite, and both the first thread 141 and the second thread 142 are threadedly sleeved with the moving plate 105.

[0027] The positioning rod 121 limits the movement of the moving plate 105. When the first motor 103 drives the lead screw 104 to rotate forward, the two moving plates 105 move closer to each other. When the first motor 103 drives the lead screw 104 to rotate in reverse, the two moving plates 105 move further apart.

[0028] The first clamping assembly 2 includes a first mounting plate 201 fixedly connected to the bottom of the movable plate 105. A first clamping plate 202 is fixedly connected to one end of the bottom of the first mounting plate 201. A first clamping pad 203 is provided on the surface of the first clamping plate 202. A first cylinder 204 is installed at the other end of the bottom of the first mounting plate 201. A first vacuum suction cup 205 is installed at the bottom of the piston rod of the first cylinder 204.

[0029] The bottom of the first vacuum suction cup 205 is higher than the bottom of the first clamping plate 202, so that the first vacuum suction cup 205 will not affect the clamping of the glass edge by the first clamping plate 202.

[0030] The fixed guide rail 107 has meshing teeth 171 on both sides of its top. The second clamping assembly 3 includes a movable frame 301 that is movably sleeved on the outside of the fixed guide rail 107. A second motor 302 is fixedly connected to the front of the movable frame 301. A cylindrical gear 303 is fixedly connected to the output shaft of the second motor 302. The cylindrical gear 303 meshes with the meshing teeth 171.

[0031] When the second motor 302 is started and drives the cylindrical gear 303 to rotate, the moving frame 301 moves horizontally along the outside of the fixed guide rail 107 through the meshing action of the cylindrical gear 303 and the meshing teeth 171.

[0032] The fixed guide rail 107 has positioning grooves 172 on both the front and back sides. The movable frame 301 has positioning sliders 311 fixedly connected to both the front and back sides of the inner wall. The positioning sliders 311 are slidably sleeved with the positioning grooves 172. The movable frame 301 has rollers 312 movably sleeved on both the top and bottom.

[0033] The positioning slider 311 and the meshing tooth 171 work together to position the movable frame 301. When the movable frame 301 moves, the roller 312 rolls against the inner wall of the positioning groove 172, so that the second gripping component 3 moves smoothly and avoids jamming.

[0034] The bottom of the movable frame 301 is fixedly connected to a second mounting plate 304. One end of the bottom of the second mounting plate 304 is fixedly connected to a second clamping plate 305. A second clamping pad 306 is provided on the surface of the second clamping plate 305. A second cylinder 307 is installed at the other end of the bottom of the second mounting plate 304. A second vacuum suction cup 308 is installed at the bottom of the piston rod of the second cylinder 307.

[0035] The bottom of the second vacuum suction cup 308 is higher than the bottom of the second clamping plate 305, and the second clamping pad 306 can increase the stability of the second clamping plate 305 and the glass edge clamping surface.

[0036] Working principle and usage process of this utility model:

[0037] The first motor 103 is started to drive the lead screw 104 to rotate. Under the thread thrust of the first thread 141 and the second thread 142, the two moving plates 105 drive the first clamping assembly 2 to move simultaneously toward each other or away from each other, so that the first clamping plate 202 clamps the front and back of glass of different lengths.

[0038] The second motor 302 is started, driving the cylindrical gear 303 to rotate. Under the meshing action of the cylindrical gear 303 and the meshing teeth 171, the movable frame 301 moves horizontally along the outer side of the fixed guide rail 107, so that the second clamping plate 305 can clamp the two sides of the glass, thus enabling the clamping of glass of different widths. Furthermore, during the movement of the first clamping assembly 2 and the second clamping assembly 3, the first vacuum suction cup 205 and the second vacuum suction cup 308 move synchronously, and the first clamping plate 202 and the second clamping plate 305... After the glass is clamped, the first cylinder 204 pushes the first vacuum suction cup 205 to adhere to the surface of the top of the glass, and the second cylinder 307 pushes the second vacuum suction cup 308 to adhere to the surface of the top of the glass. Through the external negative pressure vacuum mechanism, the first vacuum suction cup 205 and the second vacuum suction cup 308 adsorb and grasp the glass. In summary, by adjusting the distance between the first clamping component 2 and the second clamping component 3, it is possible to adapt to glass of various sizes, so that the force is uniform when clamping and adsorbing the glass, and to prevent it from falling off and causing damage to the glass.
