Description

Technical Field

[0001] This application relates to the field of laser engraving technology, and more specifically, to a laser engraving fixture for signs. Background Technology

[0002] In substations, a large number of padlocks are used to lock out operational points. Each padlock needs to be equipped with a label indicating the information of its locked operational point, such as the corresponding circuit location.

[0003] Currently, most stations use paper labels or self-adhesive labels to indicate the location of the locking operation points. These types of labels are prone to peeling, fading, and weathering over time, requiring frequent replacement and maintenance.

[0004] To effectively address the aforementioned issues, the signage material at the stations was changed to stainless steel. However, since the information on the signs needs to be laser-engraved based on the implementation information of the locked operation points, the existing laser engraving machines are too large and inconvenient to place at the stations.

[0005] Therefore, how to provide a sign laser engraving fixture that occupies less space is a technical problem that urgently needs to be solved. Utility Model Content

[0006] This application provides a laser engraving fixture for signs that can reduce space occupancy.

[0007] This application is achieved through the following technical solution: This application provides a laser engraving fixture for signs, comprising a material hopper assembly, a laser engraving machine, and a clamping mechanism. The material hopper assembly includes a working chamber and a finished product chamber connected along a first direction. The working chamber has a first receiving cavity and a first opening. The first receiving cavity is used to hold signs, and the first opening is located at one end of the first receiving cavity in a second direction and communicates with the first receiving cavity. The finished product chamber has a second receiving cavity and a second opening. The second receiving cavity is used to hold signs, and the second opening is located at one end of the second receiving cavity in a second direction and communicates with the second receiving cavity. The first direction is perpendicular to the second direction. The laser engraving machine is located on one side of the material hopper assembly in the second direction and is configured to engrave signs in the first receiving cavity through the first opening. The clamping mechanism is located on one side of the material hopper assembly in the second direction and is configured to clamp the engraved signs through the first opening and place the engraved signs into the second receiving cavity through the second opening.

[0008] The technical solution of this application embodiment, by connecting the working chamber and the finished product chamber, helps to reduce the size of the sign laser engraving fixture in the first direction, thereby reducing the space occupied by the sign laser engraving fixture in the first direction. The sign is marked by a laser engraving machine, and the marked sign is clamped from the working chamber to the finished product chamber by a clamping mechanism, which helps to improve the automation of the sign laser engraving fixture and reduce manpower.

[0009] In some embodiments, the inner wall of the first receiving cavity is provided with a plurality of first slots facing each other to accommodate signs of different sizes. The inner wall of the second receiving cavity is provided with a plurality of second slots facing each other to accommodate signs of different sizes.

[0010] The technical solution of this application embodiment provides a plurality of first slots on the inner wall of the first receiving cavity and a plurality of second slots on the inner wall of the second receiving cavity, so that the first receiving cavity and the second receiving cavity can accommodate signs of different sizes, which is beneficial to improving the applicability of the laser engraving fixture for signs.

[0011] In some embodiments, there are two working compartments connected along a first direction. There are also two finished product compartments spaced apart, with two working compartments located between them.

[0012] The technical solution of this application embodiment, by setting up two working chambers, allows the labels in both chambers to be marked simultaneously, which helps to improve the processing efficiency of the label laser engraving fixture. By setting up two finished product chambers to hold the marked labels, the capacity of the label laser engraving fixture is increased. At the same time, by placing the marked labels from one working chamber into one finished product chamber, the clamping efficiency of the clamping mechanism is improved, thereby improving the processing efficiency of the label laser engraving fixture.

[0013] In some embodiments, in the third direction, the first receiving cavity has a third opening for placing a sign inside the first receiving cavity. The working compartment includes a first body and a first movable plate, the first body forming the first receiving cavity, and the first movable plate being detachably connected to the first body to close the third opening.

[0014] The technical solution of this application embodiment, by providing a third opening, facilitates manual placement of the sign into the first receiving cavity. The provision of a detachable first movable plate improves the convenience of sign placement and enhances the reliability of sign placement in the processing chamber.

[0015] In some embodiments, the laser engraving fixture for signs further includes a lifting mechanism, which includes a first material holder and a second material holder for supporting signs. The first material holder is movably disposed in a first receiving cavity along a second direction, so that the first material holder carrying the sign moves along a first direction toward the first opening. The second material holder is movably disposed in a second receiving cavity along a second direction, so that the second material holder carrying the sign moves along a first direction away from the first opening.

[0016] The technical solution of this application embodiment improves the marking quality of the laser engraving machine by having the first material tray carry the label and move it along the first direction toward the first opening. Conversely, having the second material tray carry the label and move it away from the second opening along the first direction improves the convenience of placing the label in the finished product warehouse.

[0017] In some embodiments, the lifting mechanism further includes a first limiting member and a second limiting member. The first limiting member is disposed at the first opening and is used to restrict the first material tray from moving upward in a second direction. The second limiting member is disposed at the second opening and is used to detect the second material tray moving upward in the second direction.

[0018] The technical solution of this application embodiment reduces the risk of the first material tray moving out of the first receiving cavity by setting a first limiting member at the first opening, thereby improving the reliability of the first material tray carrying the nameplate. Similarly, by setting a second limiting member at the second opening, the risk of the second material tray moving out of the second receiving cavity by the second opening is reduced, thereby improving the reliability of the first material tray carrying the nameplate.

[0019] In some embodiments, the lifting mechanism further includes a third limiting member and a fourth limiting member. The third limiting member is disposed at the bottom of the first receiving cavity and is used to restrict the first material holder from moving downward in the second direction. The fourth limiting member is disposed at the bottom of the second receiving cavity and is used to detect the second material holder moving downward in the second direction.

[0020] The technical solution of this application embodiment reduces the risk of interference between the first material tray and the bottom wall of the working chamber by providing a third limiting member at the bottom of the first receiving cavity, thereby improving the reliability of the first material tray carrying the label. Similarly, by providing a fourth limiting member at the bottom of the second receiving cavity, the risk of interference between the second material tray and the bottom wall of the finished product chamber is reduced, further improving the reliability of the second material tray carrying the label.

[0021] In some embodiments, the laser engraving fixture for signs further includes a sign detection component, which is disposed on the first material tray and is used to detect whether the first material tray carries a sign.

[0022] The technical solution of this application embodiment, by setting a label detection component in the first material tray, can promptly remind the operator to add labels to the work chamber after the labels in the work chamber are marked, which helps to improve the processing efficiency of the label laser engraving fixture.

[0023] In some embodiments, the gripping mechanism includes a suction member, a servo motor, a swing arm, and a linear guide rail. The suction member is used to pick up a sign. The swing arm connects the servo motor and the suction member, the linear guide rail extends along a first direction, and the suction member is movably mounted on the linear guide rail.

[0024] The timely solution of this application embodiment uses a gripping mechanism to pick up the marked labels from the work chamber to the finished product chamber, which helps to improve the automation of the label laser engraving fixture and reduce manpower. By setting the gripping component on a linear guide rail, the reliability of the gripping component moving in the first direction is improved.

[0025] In some embodiments, the sign laser engraving fixture further includes a pneumatic mechanism, which includes a solenoid valve and a vacuum pump. The vacuum pump is connected to the air path of the suction component to provide negative pressure to the suction component. The solenoid valve is connected to the vacuum pump to control the on / off state of the air path.

[0026] The technical solution of this application embodiment connects a vacuum pump to the air path of the suction component, enabling the suction component to pick up the label, thus improving the reliability of the label picking up. By setting a solenoid valve to control the on / off of the air path, the suction component picks up the labeled label from the first receiving cavity and releases the labeled label into the second receiving cavity, which helps to improve the automation of the label laser engraving fixture and reduce manpower.

[0038] In some embodiments, the first direction X can be represented by the direction indicated by the letter X in the figure. The second direction Z can be represented by the direction indicated by the letter Z in the figure. The first direction X can be parallel to the length direction of the sign laser engraving fixture 1, the second direction Z can be parallel to the height direction of the sign laser engraving fixture 1, the second direction Z can be parallel to the direction of gravity, and the first direction X and the second direction Z are perpendicular.

[0039] In some embodiments, the work compartment 11 has a first receiving cavity 111 and a first opening 112, the shape of which matches the shape of the sign.

[0040] In some embodiments, the cross-section of the first receiving cavity 111 can remain unchanged along the second direction Z, and the cross-sectional shape of the first receiving cavity 111 can match the shape of the sign.

[0041] In some embodiments, the structure of the working chamber 11 may be the same as that of the finished product chamber 12. That is, the finished product chamber 12 has a second receiving cavity 121 and a second opening 122, the shape of which matches the shape of the sign.

[0042] Along the second direction Z, the cross-section of the second receiving cavity 121 can remain unchanged, and the cross-sectional shape of the second receiving cavity 121 can match the shape of the sign.

[0043] In some embodiments, the laser engraving machine 20 is located on one side of the hopper assembly 10 in the second direction Z. It is understood that, in order to facilitate the laser engraving machine 20 in marking the labels, the laser engraving machine 20 can be located above the working chamber 11, and the laser engraving machine 20 can mark the labels at the first opening 112. Alternatively, the laser engraving machine 20 can mark the labels inside the first receiving cavity 111 through the first opening 112.

[0044] In some embodiments, the laser engraving machine 20 may be located directly above the first opening 112.

[0045] In some embodiments, the gripping mechanism 30 is located on one side of the hopper assembly 10 in the second direction Z. It is understood that the gripping mechanism 30 can grip the marked tag at the first opening 112 and move it to the second opening 122, and then into the second receiving cavity 121 through the second opening 122. Alternatively, the gripping mechanism 30 can enter the first receiving cavity 111 through the first opening 112, grip the marked tag in the first receiving cavity 111 to the second opening 122, and then move it into the second receiving cavity 121 through the second opening 122.

[0046] The technical solution of this application embodiment, by connecting the working chamber 11 and the finished product chamber 12, helps to reduce the size of the sign laser engraving fixture 1 in the first direction X, thereby reducing the space occupied by the sign laser engraving fixture 1 in the first direction X. The laser engraving machine 20 marks the signs, and the clamping mechanism 30 clamps the marked signs from the working chamber 11 to the finished product chamber 12, which helps to improve the automation of the sign laser engraving fixture 1 and reduce manpower.

[0047] Please refer to Figures 1 to 5 In some embodiments, the inner wall of the first receiving cavity 111 is provided with a plurality of first slots 113 to accommodate signs of different sizes. The inner wall of the second receiving cavity 121 is provided with a plurality of second slots 123 to accommodate signs of different sizes.

[0048] In some embodiments, the third direction Y can be represented by the direction indicated by the letter Y. The third direction Y can be parallel to the width direction of the sign laser engraving fixture 1. The first direction X, the second direction Z, and the third direction Y can be perpendicular to each other.

[0049] In some embodiments, the working chamber 11 may include two first sidewalls 114 and two second sidewalls 115. The two first sidewalls 114 are disposed opposite each other along a first direction X, and the two second sidewalls 115 are disposed opposite each other along a third direction Y. The two ends of the first sidewalls 114 in the third direction Y are respectively connected to the two second sidewalls 115, and the two ends of the two second sidewalls 115 in the first direction X are respectively connected to the two first sidewalls 114. The two first sidewalls 114 and the two second sidewalls 115 together define a first receiving cavity 111.

[0050] The sign can contact the first sidewall 114 and the second sidewall 115, thereby being placed in the first receiving cavity 111.

[0051] The inner surface of the first sidewall 114 may be provided with a first slot 113, and the nameplate may contact the inner wall of the first slot 113 of the two first sidewalls 114, thereby being placed in the first receiving cavity 111.

[0052] The inner surface of the second sidewall 115 may be provided with a first slot 113, and the nameplate may contact the inner wall of the first slot 113 of the two second sidewalls 115, thereby being placed in the first receiving cavity 111.

[0053] It is understandable that the dimensions of the first sidewall 114 in the third direction Y and the second sidewall 115 in the first direction X can be the same or different. Similarly, the dimensions of the first slot 113 of the first sidewall 114 in the first direction X and the first slot 113 of the second sidewall 115 in the third direction Y can be the same or different. This allows the work compartment 11 to accommodate signs of various sizes.

[0054] In some embodiments, the finished product compartment 12 may include two third sidewalls 124 and two fourth sidewalls 125. The two third sidewalls 124 are disposed opposite each other along a first direction X, and the two fourth sidewalls 125 are disposed opposite each other along a third direction Y. The two ends of the third sidewalls 124 in the third direction Y are respectively connected to the two fourth sidewalls 125, and the two ends of the two fourth sidewalls 125 in the first direction X are respectively connected to the two third sidewalls 124. The two third sidewalls 124 and the two fourth sidewalls 125 together define a second receiving cavity 121.

[0055] The sign can contact the third sidewall 124 and the fourth sidewall 125, thereby being placed in the second receiving cavity 121.

[0056] The inner surface of the third sidewall 124 may be provided with a second slot 123, and the nameplate may contact the inner wall of the second slot 123 of the two third sidewalls 124, thereby being placed in the second receiving cavity 121.

[0057] The inner surface of the fourth side wall 125 may be provided with a second slot 123, and the nameplate may contact the inner wall of the second slot 123 of the two fourth side walls 125, thereby being placed in the second receiving cavity 121.

[0058] It is understandable that the dimensions of the third sidewall 124 in the third direction Y and the fourth sidewall 125 in the first direction X can be the same or different. Similarly, the dimensions of the second slot 123 of the third sidewall 124 in the first direction X and the second slot 123 of the fourth sidewall 125 in the third direction Y can be the same or different. This allows the finished product compartment 12 to accommodate signs of various sizes.

[0059] The technical solution of this application embodiment provides multiple slots on the inner wall of the first receiving cavity 111 and multiple slots on the inner wall of the second receiving cavity 121, so that the first receiving cavity 111 and the second receiving cavity 121 can accommodate signs of different sizes, which helps to improve the applicability of the sign laser engraving fixture 1.

[0060] Please refer to Figures 1 to 5 In some embodiments, there are two working chambers 11 connected along a first direction X. There are two finished product chambers 12, spaced apart, with the two working chambers 11 located between them.

[0061] In some embodiments, the two working compartments 11 include a first working compartment 11 and a second working compartment 11. The two finished product compartments 12 include a first finished product compartment 12 and a second finished product compartment 12. In a first direction X, the first finished product compartment 12 is connected to one side of the first working compartment 11, the side of the first working compartment 11 opposite to the first finished product compartment 12 is connected to one side of the second working compartment 11, and the side of the second working compartment 11 opposite to the first working compartment 11 is connected to the second finished product compartment 12.

[0062] The working process of the laser engraving fixture 1 is as follows: after the labels in the first working chamber 11 are marked, the clamping mechanism 30 clamps the marked labels from the first working chamber 11 to the first finished product chamber 12. After the labels in the second working chamber 11 are marked, the clamping mechanism 30 clamps the marked labels from the second working chamber 11 to the second finished product chamber 12. There can be two clamping mechanisms 30, or two clamping components within each clamping mechanism 30. The two label clamping processes can be performed simultaneously, thereby improving the efficiency of label marking and reducing the risk of interference between the two clamping processes.

[0063] The technical solution of this application embodiment, by setting two working chambers 11, allows the labels in both working chambers 11 to be marked simultaneously, which helps to improve the processing efficiency of the label laser engraving fixture 1. By setting two finished product chambers 12 to hold the marked labels, the capacity of the label laser engraving fixture 1 is increased. At the same time, the labels marked in one working chamber 11 are placed in one finished product chamber 12, which helps to improve the gripping efficiency of the clamping mechanism 30, thereby improving the processing efficiency of the label laser engraving fixture 1.

[0064] Please refer to the reference. Figure 5 In some embodiments, on the third direction Y, the first receiving cavity 111 is provided with a third opening 116 for placing a sign in the first receiving cavity 111. The working chamber 11 includes a first body 117 and a first movable plate 118. The first body 117 forms the first receiving cavity 111, and the first movable plate 118 is detachably connected to the first body 117 to close the third opening 116.

[0065] In some embodiments, the working chamber 11 includes a first body 117 and a first movable plate 118. The first body 117 can be composed of the two first sidewalls 114 and one second sidewall 115, and the first movable plate 118 can be another second sidewall 115. It is understood that when a label to be marked needs to be placed in the first receiving cavity 111, the label is placed in the first receiving cavity 111 through the third opening 116, and the first body 117 is connected by the first movable plate 118, closing the third opening 116. The first movable plate 118 can be connected to the first body 117 by bolt fastening or snap-fit ​​connection, etc. Alternatively, the first movable plate 118 can be fixed to the first body 117 by a pin positioning followed by magnetic attraction.

[0066] Similarly, in some embodiments, the finished product compartment 12 may include a second main body 127 and a second movable plate 128. The second main body 127 may be composed of the two third side walls 124 and one fourth side wall 125, and the second movable plate 128 may be another fourth side wall 125. It is understood that when the marked label needs to be removed from the second receiving cavity 121, the marked label is removed from the second receiving cavity 121 through the fourth opening 126, and the second main body 127 is connected by the second movable plate 128, closing the fourth opening 126. The second movable plate 128 can be connected to the second main body 127 by bolt fastening or snap-fit ​​connection, etc. Alternatively, the second movable plate 128 can be fixed to the second main body 127 by pin positioning and magnetic attraction.

[0067] The fourth opening 126 facilitates manual removal of the marked labels from the second receiving cavity 121. The detachable second movable plate 128 improves the ease of label removal and enhances the reliability of label placement in the finished product warehouse 12.

[0068] The technical solution of this application embodiment, by providing a third opening 116, facilitates manual placement of the sign into the first receiving cavity 111. The provision of a detachable first movable plate 118 improves the convenience of sign placement and enhances the reliability of sign placement in the processing chamber.

[0069] Please refer to Figure 1 and Figure 2 and refer to Figure 6 , Figure 6 This is a schematic diagram of a lifting mechanism provided in some embodiments of this application. In some embodiments, the sign laser engraving fixture 1 further includes a lifting mechanism 40, which includes a first material holder 41 and a second material holder 42, used to support the sign. The first material holder 41 is movably disposed in the first receiving cavity 111 along the second direction Z, so that the first material holder 41 carrying the sign moves along the first direction X toward the first opening 112. The second material holder 42 is movably disposed in the second receiving cavity 121 along the second direction Z, so that the second material holder 42 carrying the sign moves away from the first opening 112 along the first direction X.

[0070] In some embodiments, the lifting mechanism 40 may include a first linear guide rail 47, a lead screw 48, a motor 49, a first slider 50, a material support, a timing belt 51, timing teeth 52, and a nut 53. The motor 49 provides power, and the output shaft of the motor 49 drives the lead screw 48 to move circumferentially through the timing belt 51 and timing teeth 52, and then rotates it into linear motion along the second direction Z through the nut 53 and the first slider 50, thereby enabling the first material support 41 fixed on the first slider 50 to achieve linear reciprocating motion along the second direction Z.

[0071] Similarly, in some embodiments, the lifting mechanism 40 may include a first linear guide rail 47, a lead screw 48, a motor 49, a first slider 50, a material support, a timing belt 51, timing teeth 52, and a nut 53. The motor 49 provides power, and the output shaft of the motor 49 drives the lead screw 48 to move circumferentially through the timing belt 51 and timing teeth 52, and then rotates it into linear motion along the second direction Z through the nut 53 and the first slider 50, thereby enabling the second material support 42 fixed on the first slider 50 to achieve linear reciprocating motion along the second direction Z.

[0072] Understandably, the first material tray 41 can be moved along the second direction Z to the bottom of the first receiving cavity 111, and multiple labels to be marked can be placed on the first material tray 41, with the labels stacked along the second direction Z. The first material tray 41 is then moved upward along the second direction Z, so that the topmost label is located at the first opening 112. After the laser engraving machine 20 finishes marking the topmost label, the first material tray 41 continues to move upward along the second direction Z, so that the topmost marked label leaves the first receiving cavity 111 through the first opening 112, and the clamping mechanism 30 clamps the topmost marked label into the second receiving cavity 121. At this point, the marked label is removed, and the unmarked label is on top. The first material tray 41 is then moved downward along the second direction Z, so that the first material tray 41 and the labels to be marked are located in the first receiving cavity 111. Move the first material holder 41 upward along the second direction Z so that the topmost label is located at the first opening 112, and then use the laser engraving machine 20 to perform the next round of marking.

[0073] When the clamping mechanism 30 clamps the marked label above the second opening 122, the second material holder 42 is moved upward along the second direction Z to the second opening 122, so that the second material holder 42 carries the marked label. When the next marked label is clamped above the second opening 122, the second material holder 42 is moved downward along the second direction Z, so that the second material holder 42 carries the next marked label at the second opening 122.

[0074] The technical solution of this application embodiment uses a first material tray 41 to carry the label and move it along the first direction X toward the first opening 112, which helps to improve the marking quality of the label by the laser engraving machine 20. Using a second material tray 42 to carry the label and move it along the first direction X away from the second opening 122 helps to improve the convenience of placing the label in the finished product warehouse 12.

[0075] Please refer to Figures 1 to 6 In some embodiments, the lifting mechanism 40 further includes a first limiting member 43 and a second limiting member 44. The first limiting member 43 is disposed at the first opening 112 and is used to restrict the first material support 41 from moving upward along the second direction Z. The second limiting member 44 is disposed at the second opening 122 and is used to detect the second material support 42 moving upward along the second direction Z.

[0076] In some embodiments, the first limiting member 43 can be a through-beam fiber optic sensor. The second limiting member 44 can be a through-beam optical sensor.

[0077] In some embodiments, the first material holder 41 is moved upward along the second direction Z until the first limiting member 43 can detect the topmost label that needs to be marked. At this point, the first material holder 41 is stopped from moving upward along the second direction Z, so that the laser engraving machine 20 marks the topmost label that needs to be marked.

[0078] In some embodiments, the second material holder 42 is moved upward along the second direction Z until the second limiting member 44 can detect the topmost marked label. At this point, the second material holder 42 is stopped from moving upward along the second direction Z, so that the second material holder 42 carries the marked label held by the clamping mechanism 30.

[0079] The technical solution of this application embodiment reduces the risk of the first material tray 41 moving out of the first receiving cavity 111 from the first opening 112 by providing a first limiting member 43 at the first opening 112, thereby improving the reliability of the first material tray 41 in supporting the label. Similarly, by providing a second limiting member 44 at the second opening 122, the risk of the second material tray 42 moving out of the second receiving cavity 121 from the second opening 122 is reduced, further improving the reliability of the first material tray 41 in supporting the label.

[0080] Please refer to Figure 1 and Figure 2 and refer to Figure 6 In some embodiments, the lifting mechanism 40 further includes a third limiting member 45 and a fourth limiting member 46. The third limiting member 45 is disposed at the bottom of the first receiving cavity 111 and is used to restrict the first material support 41 from moving downward along the second direction Z. The fourth limiting member 46 is disposed at the bottom of the second receiving cavity 121 and is used to detect the second material support 42 moving downward along the second direction Z.

[0081] In some embodiments, the third limiting member 45 may be a proximity sensor. The fourth limiting member 46 may be a proximity sensor.

[0082] In the initial state, the first material holder 41 is moved along the second direction Z to the bottom of the first receiving cavity 111 until the third limiting member 45 detects the first material holder 41, at which point the first material holder 41 stops moving downward along the second direction Z.

[0083] When the second material tray 42 carries a large number of labels, it gradually moves downwards along the second direction Z to the bottom of the second receiving cavity 121 until the fourth limiting member 46 detects the second material tray 42. At this point, the second material tray 42 stops moving downwards along the second direction Z. The second movable plate 128 is then opened to remove the labeled labels.

[0084] The technical solution of this application embodiment reduces the risk of interference between the first material tray 41 and the bottom wall of the working chamber 11 by providing a third limiting member 45 at the bottom of the first receiving cavity 111, thereby improving the reliability of the first material tray 41 in carrying the label. Similarly, by providing a fourth limiting member 46 at the bottom of the second receiving cavity 121, the risk of interference between the second material tray 42 and the bottom wall of the finished product chamber 12 is reduced, thereby improving the reliability of the second material tray 42 in carrying the label.

[0085] Please refer to Figure 1 and Figure 2 and refer to Figure 6 In some embodiments, the lifting mechanism 40 further includes a label detection component 60, which is disposed on the first material tray 41 and is used to detect whether the first material tray 41 carries a label.

[0086] In some embodiments, the sign detection element 60 may be a diffuse reflection fiber optic sensor.

[0087] In some embodiments, the label detection element 60 may be disposed at the bottom of the first material tray 41. The first material tray 41 may be provided with a through hole extending through the first material tray 41 in the second direction Z. The label detection element 60 detects whether the first material tray 41 carries a label through the first material tray 41. If it is detected that the first material tray 41 does not carry a label, the label in the first receiving cavity 111 is marked and clamped into the second receiving cavity 121. At this time, the first movable plate 118 needs to be opened to place the label to be marked into the first receiving cavity 111.

[0088] The technical solution of this application embodiment, by setting a label detection component 60 in the first material tray 41, can promptly remind the operator to add labels to the work chamber 11 after the labels in the work chamber 11 are marked, which helps to improve the processing efficiency of the label laser engraving fixture 1.

[0089] Please refer to Figure 1 and Figure 2 and refer to Figure 7 , Figure 7 This is a schematic diagram of a gripping mechanism provided in some embodiments of this application. In some embodiments, the gripping mechanism 30 includes a suction member 31, a servo motor 32, a swing arm 33, and a second linear guide rail 34. The suction member 31 is used to pick up a sign. The swing arm 33 connects the servo motor 32 and the suction member 31, and the second linear guide rail 34 extends along a first direction X, with the suction member 31 movably disposed on the second linear guide rail 34.

[0090] In some embodiments, the gripping mechanism 30 may further include a linear cam 35 and a first slider 36. The linear cam 35 is connected to the swing arm 33, and the first slider 36 is connected to the second linear guide rail 34 and the linear cam 35. The suction member 31 is disposed on the linear cam 35. The servo motor 32 drives the swing arm 33 to move, which, in conjunction with the linear cam 35 and the first slider 36, performs reciprocating linear motion along the first direction X on the second linear guide rail 34, thereby driving the suction member 31 to move.

[0091] After the laser engraving machine 20 finishes marking the labels in the work chamber 11, the suction member 31 moves along the first direction X towards the first opening 112 to pick up the marked labels. Then, it moves along the first direction X towards the second opening 122 and places the marked labels into the second receiving cavity 121. The suction member 31 continues to move along the first direction X towards the first opening 112 to pick up the marked labels.

[0092] The timely solution of this application embodiment uses the suction member 31 of the clamping mechanism 30 to clamp the marked labels from the working chamber 11 to the finished product chamber 12, which helps to improve the automation of the label laser engraving fixture 1 and reduce manpower. By setting the suction member 31 on the second linear guide rail 34, the reliability of the suction member 31 moving along the first direction X is improved.

[0093] Please refer to Figure 1 and Figure 2 and refer to Figure 8 , Figure 8 This is a schematic diagram of a pneumatic mechanism provided in some embodiments of this application. In some embodiments, the nameplate laser engraving fixture 1 further includes a pneumatic mechanism 70, which includes a solenoid valve 71 and a vacuum pump 72. The vacuum pump 72 is connected to the air passage of the suction member 31 to provide negative pressure to the suction member 31. The solenoid valve 71 is connected to the vacuum pump 72 to control the opening and closing of the air passage.

[0094] In some embodiments, the vacuum pump 72 is connected to the solenoid valve 71 and the suction member 31 via a gas pipe.

[0095] After the laser engraving machine 20 finishes marking the labels in the working chamber 11, the suction member 31 moves along the first direction X towards the first opening 112. The solenoid valve 71 opens the air path, causing the vacuum pump 72 to provide negative pressure to the suction member 31. After the suction member 31 picks up the marked labels, it moves along the first direction X towards the second opening 122. The solenoid valve 71 then disconnects the air path, and the suction member 31 releases the marked labels, placing them into the second receiving chamber 121.

[0096] The technical solution of this application embodiment connects the vacuum pump 72 to the air path of the suction member 31, enabling the suction member 31 to pick up the labels, which improves the reliability of the suction member 31 in picking up the labels. By setting the solenoid valve 71 to control the opening and closing of the air path, the suction member 31 picks up the labeled labels from the first receiving cavity 111 and releases the labeled labels into the second receiving cavity 121, which improves the automation of the label laser engraving fixture 1 and reduces manpower.

[0097] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
