Description

Technical Field

[0001] This invention relates to the field of marking technology for current transformer housings, specifically to a multi-face marking device for open-type current transformer plastic housings. Background Technology

[0002] A laser marking machine is a device that focuses a laser beam with extremely high energy density onto the surface of the object to be marked. The surface of the object is vaporized through burning and etching, and patterns or text are precisely etched by controlling the effective displacement of the laser beam.

[0003] Instrument transformers, also known as instrument transformers, are a general term encompassing current transformers and voltage transformers. They transform high voltage into low voltage and large current into small current, and are mainly used in instrumentation, power protection systems, and automated control systems.

[0004] During the production of instrument transformers, markings need to be applied to the transformer casing. For example, the existing equipment, published under CN217493071U and named "Automatic Marking Device for Instrument Transformer Casings," can achieve highly efficient continuous automated marking, but it can only mark one side of the instrument transformer casing. When marking multiple sides of the instrument transformer casing is required, only semi-automatic marking equipment can be selected. By manually flipping the instrument transformer casing, the problem of a large amount of manual operation and very low marking efficiency still exists. Summary of the Invention

[0005] To address the technical problem that existing instrument transformer marking equipment cannot mark multiple sides and requires manual flipping of the instrument transformer casing, resulting in a large workload for operators and low marking efficiency, this invention provides a multi-sided marking device for open-type instrument transformer plastic casings. This device can meet the multi-sided marking requirements of instrument transformer casings, significantly reduce the workload for operators, and greatly improve marking efficiency.

[0006] The technical solution adopted by the present invention is to provide a multi-sided marking device for an open-type current transformer plastic shell, including an operating table, a laser marking machine set on the operating table, a material changing mechanism set on the operating table and corresponding to the laser marking machine, and a material feeding mechanism set on the operating table.

[0010] The swing frame includes a side fixing plate arranged opposite to each other, a middle fixing plate arranged between the lower ends of the side fixing plates, and a clearance hole arranged on the middle fixing plate and corresponding to the rotation axis. The mounting plate is fixed to the outside of the middle fixing plate and the front end of the rotation axis passes through the clearance hole and extends into the space between the side fixing plates. The center position of the side fixing plate, the center position of the rotary cylinder drive end, and the center position of the support block are located on the same axis.

[0011] The material feeding mechanism includes a pushing and feeding unit set on the operating table and corresponding to the material changing mechanism. The pushing and feeding unit includes a pushing slide cylinder set on the operating table, a pushing base plate set on the movable end of the pushing slide cylinder, a clamping slide cylinder set on the pushing base plate, a clamping seat set on the movable end of the clamping slide cylinder, a clamping plate set on the inner end of the clamping seat, a pushing seat set on the pushing base plate, and a baffle plate set on the upper end of the pushing seat.

[0012] The pusher slide cylinder drives the pusher base plate to move towards the material changing mechanism. The baffle plate extends above the clamping seat and is opposite to the clamping plate. The front end of the rotating shaft corresponds to the position between the clamping plate and the baffle plate. The clamping slide cylinder is located outside the clamping seat and drives the clamping seat to move the clamping plate towards the baffle plate.

[0013] The material feeding mechanism further includes a clamping and feeding unit mounted on the operating table. The clamping and feeding unit includes a clamping support frame mounted on the operating table, a clamping transverse slide cylinder mounted on the clamping support frame, a clamping lifting slide cylinder mounted on the movable end of the clamping transverse slide cylinder, a gripper cylinder mounted on the lower end of the clamping lifting slide cylinder, and clamping clamping plates mounted on the two movable ends of the gripper cylinder respectively. The gripper cylinder has the freedom of translation and lifting driven by the clamping transverse slide cylinder and the clamping lifting slide cylinder. The gripper cylinder is vertically aligned with the clamping seat.

[0014] The material feeding mechanism further includes a vibrating feeding mechanism, which includes a vibrating feeding plate located on one side of the operating table, a feeding chute located at the output end of the vibrating feeding plate, a receiving support frame located on the operating table, a receiving seat located at the upper end of the receiving support frame, a receiving groove located at the upper end of the receiving seat, and a receiving baffle located on the outside of the receiving seat.

[0015] The receiving groove has a through groove structure with openings at the front and back.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention uses a material changing mechanism to change the marking surface of the current transformer shell corresponding to the laser marking machine. This includes switching the four sides and switching the side and bottom surfaces, allowing the laser marking machine to mark five surfaces of the current transformer shell.

Detailed Implementation

[0028] like Figure 1-3As shown, the present invention provides a multi-face marking device for an open-type current transformer plastic shell, including an operating table 2, a laser marking machine 1 mounted on the operating table 2, a material changing mechanism mounted on the operating table 2 and corresponding to the laser marking machine 1, and a material feeding mechanism mounted on the operating table 2. The material changing mechanism includes a positioning support frame 3 mounted on the operating table 2, a rotary cylinder 4 mounted on the positioning support frame 3, a swing frame mounted on the drive end of the rotary cylinder 4, a mounting plate 5 mounted on the swing frame, a rotating shaft 6 mounted on the mounting plate 5, a shell support block 7 mounted at the front end of the rotating shaft 6, a tensioning spring 8 mounted on the side of the shell support block 7, a pulley 9 mounted at the rear end of the rotating shaft 6, a changing motor 10 mounted on the rear side of the mounting plate 5, and a changing mechanism for the changing mechanism. The motor 10 has a drive wheel 11 at its drive end and a transmission belt 12 on the pulley 9 and the drive wheel 11; the drive end of the rotary cylinder 4 is fixed to one side of the swing frame, and the swing frame has a degree of freedom of rotation driven by the rotary cylinder 4; the rotating shaft 6 is rotatably mounted on the mounting plate 5 and its rear end extends backward through the mounting plate 5; the pulley 9 is fixed to the rear end of the rotating shaft 6; the face-changing motor 10 is fixed to the rear side of the mounting plate 5 and the drive wheel 11 corresponds to the pulley 9; the face-changing motor 10 drives the rotating shaft 6 to rotate on the mounting plate 5 through the drive wheel 11, the pulley 9 and the transmission belt 12; the support block 7 is fixed to the front end of the rotating shaft 6 and rotates synchronously with the rotating shaft 6; the laser generating end of the laser marking machine 1 corresponds vertically to the support block 7.

[0029] The current transformer housing in this invention is a rectangular housing with an opening at the top, having four sides and a bottom surface. This device can laser mark the four sides and the bottom surface of the current transformer housing.

[0030] This invention comprises an operating table 2, a laser marking machine 1, a material changing mechanism, and a material feeding mechanism. The laser marking machine 1 is an existing marking machine, and its laser head can be raised, lowered, and translated (i.e., moved along the XZ axis). The operating table 2 is a hollow box-type structure used for the installation and support of the material changing mechanism and the material feeding mechanism. The material changing mechanism is used for changing the surface of the current transformer housing, and the material feeding mechanism is used to transport the current transformer housing onto the material changing mechanism.

[0031] In the material changing mechanism of the present invention, two positioning support frames 3 are arranged opposite each other. The specific structure of the positioning support frames 3 is not limited, and they are used to support and install the rotary cylinder 4. The rotary cylinder 4 is installed on the opposite side of one of the positioning support frames 3. One side of the swing frame is installed on the drive end of the rotary cylinder 4, and the other side is rotatably connected to the other positioning support frame 3. Driven by the rotary cylinder 4, the swing frame can rotate stably. The mounting plate 5 is fixed on the swing frame and can swing synchronously with the swing frame. The rotating shaft 6 is rotatably installed on the mounting plate 5. The mounting plate 5 has mounting holes, and bearings are fixed inside the mounting holes. A rotating shaft 6 is inserted into and fixed inside the bearings, allowing the rotating shaft 6 to rotate on the mounting plate 5. The front end of the rotating shaft 6 extends forward towards the front of the mounting plate, and the rear end extends backward towards the rear of the mounting plate. A pulley 9 is fixed to the rear end of the rotating shaft 6. A face-changing motor 10 is mounted on the rear side of the mounting plate, and a drive wheel 11 fixed to the drive end of the face-changing motor 10 corresponds to the pulley 9 and is driven by a transmission belt 12, allowing the face-changing motor 10 to drive the rotating shaft 6 on the mounting plate 5. The rotating mechanism rotates; the support block 7 is fixed to the front end of the rotating shaft 6, and its side is provided with a tensioning spring 8. The tensioning spring 8 is V-shaped, with one end of the opening of the tensioning spring 8 fixed to the side of the support block 7 and the other end being a movable end. The dimensions of the support block 7 and the tensioning spring 8 are designed according to the dimensions of the transformer housing. In use, the support block 7 can be inserted through the opening of the transformer housing and is tensioned against the inner wall of the transformer housing through the tensioning spring 8, thereby limiting the position of the transformer housing without affecting the marking on the sides and bottom of the transformer housing. The rotary cylinder 4 drives the swing frame to rotate. The device allows the corresponding surface of the current transformer housing and the laser emitting end of the laser marking machine 1 to be switched between the side and bottom surfaces. The face-changing motor 10 drives the rotating shaft 6 to rotate, and the current transformer housing, which is limited at the front end of the rotating shaft 6, rotates synchronously. This allows the corresponding surface of the current transformer housing and the laser emitting end of the laser marking machine 1 to be switched between the four sides, enabling the laser marking machine 1 to mark the four sides and the bottom surface of the current transformer housing. This meets the multi-face marking requirements of the current transformer housing, eliminates the need for manual flipping by the operator, greatly reduces the workload of the operator, and significantly improves the marking efficiency.

[0032] like Figure 2-3 As shown, it also includes a pusher cylinder 13 disposed on the rear side of the mounting plate 5 and a pusher shaft 14 disposed in the rotating shaft 6; the support block 7 has a sleeve hole in the middle and is fitted and fixed on the front end of the rotating shaft 6. The rotating shaft 6 is a hollow shaft. The pusher shaft 14 is slidably inserted into the rotating shaft 6. The telescopic end of the pusher cylinder 13 is fixed to the rear end of the pusher shaft 14. The pusher shaft 14 has the freedom to slide within the rotating shaft 6 by means of the pusher cylinder 13.

[0033] The rotating shaft 6 is a hollow shaft with a through hole running through its central axis. The pusher shaft 14 is inserted into the rotating shaft 6, with its front end inside and its rear end extending out. A pusher cylinder 13 is mounted on the rear side of the mounting plate 5 via a bracket (the specific structure of the bracket is not limited). The telescopic end of the pusher cylinder 13 is fixed to the rear end of the pusher shaft 14, allowing the pusher shaft 14 to slide within the rotating shaft 6. A support block 7 is fitted and fixed to the front end of the rotating shaft 6 through a sleeve hole. The front end of the rotating shaft 6 is located within the sleeve hole, and under the action of the pusher cylinder 13, the front end of the pusher shaft 14 can extend from inside the front end of the rotating shaft 6 and out of the sleeve hole. During use... The initial position of the rotary cylinder 4 is with the rotating shaft 6 horizontal. The current transformer housing is moved to the support block 7 for limiting through the material feeding mechanism. The drive end of the rotary cylinder 4 rotates 90° to the end position, and the rotating shaft 6 is vertically upward and corresponds to the laser head of the laser marking machine 1, realizing the conversion of the side of the current transformer housing to the bottom. After marking is completed, the rotary cylinder 4 rotates back to the initial position, and the pusher cylinder 13 drives the pusher shaft 14 to extend forward, pushing the current transformer housing outward until it is separated from the support block 7 and falls downward, completing the unloading. This design only requires a regular rotary cylinder 4, and only needs to control the reciprocating motion from the initial to the end position to complete the feeding, marking and unloading. It is simple to control, has high precision and low cost.

[0034] like Figure 2-3 As shown, it also includes a pusher plate 15 disposed at the rear end of the pusher shaft 14. The rotating shaft 6 and the pusher shaft 14 are arranged side by side and spaced apart. The rear ends of the multiple pusher shafts 14 are all fixed to the front side of the pusher plate 15. The telescopic end of the pusher cylinder 13 is fixed to the rear side of the pusher plate 15.

[0035] Multiple sets of rotating shafts 6 and pusher shafts 14 can complete multi-face marking of multiple current transformer housings at one time, and the pusher plate 15 can allow the pusher cylinder 13 to unload multiple current transformer housings at one time, further improving the marking efficiency.

[0036] like Figure 2 As shown, the swing frame includes a side fixing plate 16 arranged opposite to each other, a middle fixing plate 17 arranged between the lower ends of the side fixing plates 16, and a clearance hole 18 arranged on the middle fixing plate 17 and corresponding to the rotation shaft 6. The mounting plate 5 is fixed to the outside of the middle fixing plate 17 and the front end of the rotation shaft 6 passes through the clearance hole 18 and extends into the space between the side fixing plates 16. The center position of the side fixing plate 16, the center position of the drive end of the rotary cylinder 4, and the center position of the support block 7 are located on the same axis.

[0037] The swing frame consists of two side fixing plates 16 and a middle fixing plate 17, forming an overall U-shaped structure. The front end of the rotating shaft 6, i.e., the position of the current transformer housing during marking, is located inside the opening of the swing frame. When the swing frame rotates through this structure, i.e. when the current transformer housing changes sides, the center position of the side fixing plate 16, the center position of the drive end of the rotary cylinder 4, and the support block 7 can be used as the center line of rotation. The side or bottom surface of the current transformer can always maintain precise correspondence with the laser head of the laser printer 1, further improving the marking accuracy and marking quality.

[0038] like Figure 1 and 4 As shown in Figure 7, the material feeding mechanism includes a pushing and feeding unit mounted on the operating table 2 and corresponding to the material changing mechanism. The pushing and feeding unit includes a pushing slide cylinder 19 mounted on the operating table 2, a pushing base plate 20 mounted on the movable end of the pushing slide cylinder 19, a clamping slide cylinder 21 mounted on the pushing base plate 20, a clamping seat 22 mounted on the movable end of the clamping slide cylinder 21, a clamping plate 23 mounted on the inner end of the clamping seat 22, and a clamping plate 23 mounted on the pushing base plate 20. The pusher seat 24 on the plate 20 and the baffle plate 25 set on the upper end of the pusher seat 24; the pusher slide cylinder 19 drives the pusher base plate 20 to move towards the material changing mechanism, the baffle plate 25 extends into the clamping seat 22 and is opposite to the clamping plate 23, the front end of the rotating shaft 6 corresponds to the position between the clamping plate 23 and the baffle plate 25, the clamping slide cylinder 21 is located outside the clamping seat 22 and drives the clamping seat 22 to move the clamping plate 23 towards the baffle plate 25.

[0039] The feeding unit is used to push the transformer housing onto the support block 7 at the front end of the rotating shaft 6. It consists of a pushing slide cylinder 19, a pushing base plate 20, a clamping slide cylinder 21, a clamping seat 22, a clamping plate 23, a pushing seat 24, and a baffle plate 25. The pushing slide cylinder 19 drives the pushing base plate 20 to move towards the front end of the rotating shaft 6, and the clamping slide cylinder 21 drives the clamping plate 23 on the clamping seat 22 to move towards the baffle plate 25 on the pushing seat 24, clamping the transformer housing onto both sides. On one side, the current transformer housing is positioned with its opening facing the rotating shaft 6. During use, the current transformer housing is conveyed between the clamping plate 23 and the baffle plate 25, with the opening of the housing facing the front end of the rotating shaft 6. The clamping slide cylinder 21 drives the clamping plate 23, which, in conjunction with the baffle plate 25, clamps the current transformer housing. Finally, the pushing slide cylinder 19 moves the current transformer housing, clamped above the pushing base plate 20, towards the front end of the rotating shaft 6 until the opening of the current transformer housing fits onto the support block 7 at the front end of the rotating shaft 6. This structure can accurately transfer the current transformer housing to the front end of the rotating shaft 6 of the material changing mechanism, ensuring stable operation and precise feeding.

[0040] like Figure 1 and 4As shown in Figure 7, the material feeding mechanism further includes a clamping and feeding unit mounted on the operating table 2. The clamping and feeding unit includes a clamping support frame 26 mounted on the operating table 2, a clamping transverse sliding table cylinder 27 mounted on the clamping support frame 26, a clamping lifting sliding table cylinder 28 mounted on the movable end of the clamping transverse sliding table cylinder 27, a gripper cylinder 29 mounted on the lower end of the clamping lifting sliding table cylinder 28, and clamping clamping plates 30 mounted on the two movable ends of the gripper cylinder 29 respectively. The gripper cylinder 29 has the freedom of translation and lifting driven by the clamping transverse sliding table cylinder 27 and the clamping lifting sliding table cylinder 28. The gripper cylinder 29 corresponds vertically to the clamping seat 22.

[0041] The clamping and feeding unit is used to clamp the current transformer housing and move it between the clamping plate 23 and the baffle plate 25 of the pushing and feeding unit. The clamping and feeding unit consists of a clamping support frame 26, a clamping transverse slide cylinder 27, a clamping lifting slide cylinder 28, a gripper cylinder 29, and a clamping clamping plate 30. The clamping support frame 26 adopts a gantry structure, and the pushing and feeding unit is located below the gantry. The clamping transverse slide cylinder 27 and the clamping lifting slide cylinder 28 can drive the gripper cylinder 29 to move up, down, and horizontally. In use, the initial position is the current transformer housing feeding position, and the lifting... The lowering slide cylinder 28 drives the gripper cylinder 29 to descend. The movable end of the gripper cylinder 29 points vertically downward and, by driving the two clamping plates 30 to move relative to each other, clamps both sides of the current transformer housing. Then, the lifting slide cylinder 28 drives the gripper cylinder 29 to rise, and under the action of the clamping transverse slide cylinder 27, it moves to the corresponding position above the clamping plate 23 and the baffle plate 25. The lifting slide cylinder 28 then drives the gripper cylinder 29 to descend until the current transformer housing clamped by the gripper cylinder 29 enters between the clamping plate 23 and the baffle plate 25, at which point it is released, thus achieving material loading. In this embodiment, the height of the clamping plate 23 and the baffle plate 25 is designed to be half the height of the current transformer housing. The clamping plates 30 clamp the upper half of the current transformer, and the clamping plates 30 are released after the lower half of the current transformer housing is smoothly placed between the clamping plates 23 and the baffle plate 25, resulting in a more stable and precise loading process. This structure can accurately and smoothly deliver the transformer housing between the clamping plate 23 and the baffle plate 25. It is simple, effective, and stable in operation.

[0042] like Figure 1 and 4As shown, the material feeding mechanism also includes a vibrating feeding mechanism. The vibrating feeding mechanism includes a vibrating feeding plate 31 located on one side of the operating table 2, a feeding slide 32 located at the output end of the vibrating feeding plate 31, a receiving support frame 33 located on the operating table 2, a receiving seat 34 located on the upper end of the receiving support frame 33, a receiving groove 35 located on the upper end of the receiving seat 34, and a receiving baffle 36 located on the outside of the receiving seat 34. The receiving groove 35 has a through groove structure with openings at the front and back. The front end of the receiving seat 34 corresponds to the output end of the feeding slide 32, and the front end of the receiving groove 35 communicates with the inner cavity of the feeding slide 32. The receiving baffle 36 is fixed to the rear end of the receiving seat 34 and closes the rear end opening of the receiving groove 35. The receiving seat 34 is located on one side of the pushing feeding unit and corresponds to the gripper cylinder 29.

[0043] The current transformer housing is continuously fed via a vibrating feeding plate 31 and slides within the feeding chute 32 into the receiving groove 35 at the upper end of the receiving seat 34. The receiving baffle 36 at the rear end of the receiving seat 34 limits the current transformer housing within the receiving groove 35, keeping it stationary and awaiting feeding by the clamping unit. In this embodiment, the depth of the receiving groove 35 does not exceed half the height of the current transformer housing, ensuring that the upper part of the housing protrudes after entering the groove, facilitating clamping by the gripper cylinder 29. This structure is simple, effective, and provides precise positioning and convenient clamping.

[0044] like Figure 1 As shown, it also includes a material discharge and guiding mechanism. The operating table 2 is a box-type structure with an inner cavity. The material guiding mechanism includes a material discharge port 37 set on the operating table 2 and corresponding to the material changing mechanism, and a material discharge slide 38 set inside the operating table 2 and corresponding to the material discharge port 37. The material discharge slide 38 has a U-shaped structure, with its inner end above the material discharge port 37 corresponding to the material changing mechanism, and its outer end inclined downward and extending outward through one side of the operating table 2.

[0045] The material changing mechanism is located above the material discharge port 37. After marking is completed, when the rotary cylinder 4 drives the swing frame to rotate to a horizontal state, that is, when the rotating shaft 6 is in a horizontal state, the pusher shaft 14 extends from the front end of the rotating shaft 6 under the drive of the pusher cylinder, pushing the current transformer housing on the front support block 7 of the rotating shaft 6 forward until the current transformer housing separates from the support block 7. Finally, the pusher shaft 14 retracts into the rotating shaft 6, and the current transformer housing falls into the material discharge slide 38 after losing support and limit, and slides outward under the guidance of the material discharge slide 38. A conveying mechanism or storage box can be set at the corresponding position outside the operating table 2 to send the current transformer housing to the next process or for storage. This design has a simple structure, low cost, and is easy to use.
