[0002] As we all know, the glass used in electronic products, such as screens or back shells, has the characteristics of high hardness, thinness, lightness and small area. Due to the particularity of the application field, the production of this type of glass often requires fast and batch precision processing. Therefore, it is inseparable from the use of precision engraving machines. In the production process of existing precision engraving machines, many steps need to be completed manually, and many precision engraving machines are to set a positioning fixture at a fixed position on the workbench, and then use a vacuum suction cup to absorb the glass, and then the vacuum suction cup is moved to the positioning fixture for positioning in order to carry out the subsequent process, such as placing the positioned glass accurately in the subsequent vacuum adsorption fixture, but the distance when the vacuum suction cup moves to the positioning fixture is large, which greatly wastes time.

[0003] Prior art, patent number (CN201920181984.6) mentions an external manipulator of a precision engraving machine, including an X-axis linear slide sliding on a worktable, an X-axis driver connected to the X-axis linear slide and the worktable, a Z-axis linear slide sliding on the X-axis linear slide, a Z-axis driver connected to the Z-axis linear slide and the X-axis linear slide, a Y-axis linear slide sliding on the Z-axis linear slide, a Y-axis driver connected to the Y-axis linear slide and the Z-axis linear slide, a pick-and-place assembly installed on the Y-axis linear slide, a flip seat pivotally connected to the Z-axis linear slide by a pivot axis and having at least a positioning position and an avoidance position relative to the Z-axis linear slide, a flip driver installed on the Z-axis linear slide, and a positioning fixture installed on the flip seat and following the flip seat to switch between the positioning position and the avoidance position. When the positioning fixture is in the positioning position, it is located below the corresponding pick-and-place assembly to achieve automatic loading and unloading between a material rack and a vacuum adsorption fixture; more importantly, it saves space and has high speed.

[0004] In the prior art, a flip drive, an X-axis linear slide, a Z-axis linear slide and a Y-axis linear slide are added, which effectively solves the problem that in the production process of the precision engraving machine, many steps need to be manually transported, which greatly wastes time. However, due to the overly complex overall structure, its only three-axis motion trajectory cannot be effectively and timely transported or moved in actual practical applications, which greatly reduces the practicability of the external robot arm of the precision engraving machine.

[0008] Among them, the multi-axis positioning clamping assembly also includes a positioning column and a rubber pad. The positioning column is detachably connected to the clamping plate and is located around the side of the positioning column away from the multi-axis robotic arm. The rubber pad is detachably connected to the clamping plate and is located inside the side of the clamping plate away from the multi-axis robotic arm.

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] First embodiment

[0020] See also Figure 1 to Figure 3 , Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a side view of the whole of the first embodiment of the utility model. Figure 3 It is an overall top view of the first embodiment of the utility model.

[0021] The utility model provides an external manipulator for a precision engraving machine, comprising a base 101 and a multi-axis positioning and clamping assembly, wherein the multi-axis positioning and clamping assembly comprises a sliding groove 102, a sliding block 103, a placement seat 104, a multi-axis mechanical arm 106, a protective ring 105, a clamping plate 107, a positioning column 108, a rubber pad 109, a clamping ring 110 and a separation pad 111. The above-mentioned scheme solves the problem that the external manipulator structure of a traditional precision engraving machine is too complicated, resulting in its only three-axis motion trajectory in actual practical application being unable to be effectively and timely transported or moved, thereby greatly reducing the practicality of the external manipulator of the precision engraving machine. It can be understood that the above-mentioned scheme can be used to slide the sliding block 103 in the sliding groove 102 when clamping and loading the raw materials of the precision engraving machine for transportation, thereby effectively adjusting the specific position of the Y-axis. At the same time, the multi-axis mechanical arm 106 adopts the existing The common six-axis robotic arm works, and thus after the placement seat 104 reaches the specified position of the Y-axis, it is more flexible than the traditional driving mechanism and has a simpler structure. Therefore, the flip drive, X-axis linear slide, Z-axis linear slide and Y-axis linear slide are replaced by the multi-axis mechanical clamping assembly, which will effectively retain the beneficial effects of the original technology. When the multi-axis robotic arm 106 sends the clamping plate 107 to the specified position, the position of the clamping ring 110 will be limited by the positioning column 108, and the rubber pad 109 will provide protection, thereby clamping and transporting the raw material. At this point, while retaining the original beneficial effects, it effectively solves the problem that the external robot arm of the traditional engraving machine is too complicated in structure, resulting in its only three-axis motion trajectory in actual practical application. It will not be able to be effectively and timely transported or moved, thereby greatly reducing the practicality of the external robot arm of the engraving machine.

[0022] According to this specific embodiment, the sliding groove 102 is fixedly connected to the base 101 and is located inside the base 101, the sliding block 103 is slidably connected to the base 101 and is located inside the base 101, and the sliding block 103 is arranged inside the sliding groove 102, the placement seat 104 is detachably connected to the sliding block 103 and is located above the sliding block 103, the multi-axis robot arm 106 is detachably connected to the placement seat 104 and is located above the placement seat 104, the base 101 is the main functional structural component, and the sliding groove 102 is the place for placing the sliding block 103, and the sliding block 103 is a functional structural component for adjusting the specific position of the placement seat 104 on the Y-axis, and the multi-axis robot arm 106 is a functional component that mainly realizes multi-axis rotation.

[0023] Among them, the protective ring 105 is detachably connected to the multi-axis robot 106 and is located on the outer surface of one end of the multi-axis robot 106 close to the mounting seat 104, and the clamping plate 107 is detachably connected to the multi-axis robot 106 and is located at one end of the multi-axis robot 106 away from the mounting seat 104. The protective ring 105 is an auxiliary component for protecting the multi-axis robot 106, and the clamping plate 107 is a functional structural component for clamping raw materials.

[0024] Secondly, the positioning column 108 is detachably connected to the clamping plate 107 and is located around the side of the positioning column 108 away from the multi-axis robot 106. The rubber pad 109 is detachably connected to the clamping plate 107 and is located inside the side of the clamping plate 107 away from the multi-axis robot 106. The positioning column 108 is a functional structural component that facilitates the clamping plate 107 to lock the position of the raw material, and the rubber pad 109 is an auxiliary structural component that mainly protects the raw material from being damaged by external factors during the clamping process.

[0025] At the same time, the clamping ring 110 is detachably connected to the clamping plate 107 and is located at the center of one side of the clamping plate 107 away from the multi-axis robot 106 , the separation pad 111 is detachably connected to the base 101 and is located above the base 101 , and the separation pad 111 is arranged on one side of the placement seat 104 .

[0026] When the utility model is used to clamp and load the raw materials of the engraving machine, the sliding block 103 will slide in the sliding groove 102, thereby effectively adjusting the specific position of the Y axis. At the same time, the multi-axis mechanical arm 106 adopts the six-axis mechanical arm commonly seen in the existing market to work. Therefore, after the placement seat 104 reaches the specified position of the Y axis, it is more flexible than the traditional driving mechanism and has a simpler structure. Therefore, after the flip driver, the X-axis linear slide, the Z-axis linear slide and the Y-axis linear slide are replaced by the multi-axis mechanical clamping assembly, it will be effective. While retaining the beneficial effects of the original technology, when the multi-axis robot 106 sends the clamping plate 107 to the specified position, the positioning column 108 will limit the position of the clamping ring 110, and the rubber pad 109 will provide protection, so that the raw material can be clamped and transported. At the same time, the original beneficial effects are retained and the problem that the external robot structure of the traditional engraving machine is too complicated, resulting in its only three-axis motion trajectory being unable to be effectively and timely transported or moved in actual practical applications, thereby greatly reducing the practicality of the external robot of the engraving machine.

[0030] According to this specific embodiment, the processing plate 201 is detachably connected to the base 101 and is located above one side of the base 101. The positioning plate 202 is detachably connected to the processing plate 201 and is located above the processing plate 201. The positioning cavity 203 is fixedly connected to the positioning plate 202 and is located inside the positioning plate 202. The limiting column 204 is detachably connected to the positioning plate 202 and is located inside the positioning plate 202, and the limiting column 204 is arranged inside the positioning cavity 203. After the clamping plate 107 and the clamping ring 110 clamp the raw material to the specified position, they will be placed on the positioning plate 202 on the processing plate 201, thereby limiting the positioning of the limiting column 204 with the positioning cavity 203 to prevent deviation from affecting subsequent work.
