Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology and relates to a material setting fixture, in particular to a flip-type double-sided processing device and laser engraving equipment. Background Art

[0002] In the manufacturing industry, laser technology is widely used in various processes, including welding, surface treatment, and QR code laser engraving. However, in actual production, especially in the double-sided laser engraving process of products, there are a series of challenges. The main challenges are as follows:

[0003] 1. Complexity of product positioning and fixation: In the traditional laser engraving process, whenever different surfaces of the workpiece need to be processed, the workpiece often needs to be manually flipped. This process is not only time-consuming, but also has problems with the accuracy of repeated positioning. Each flip and repositioning may introduce errors, which is particularly critical for manufacturing fields that require high-precision processing. In addition, for special-shaped workpieces, the jigs and fixtures of the laser engraving equipment need to be replaced or adjusted for different products, further increasing the complexity of processing and equipment costs.

[0004] 2. Limitation of automation level: Although fully automatic equipment can provide higher efficiency and precision, for some small and medium-sized enterprises, the high cost makes the investment in fully automatic equipment not economical. Therefore, many occasions still rely on semi-automatic or manually operated equipment, which limits production efficiency and expansion capabilities.

[0005] 3. Risk of product damage: When manually flipping the workpiece, improper operation can easily cause scratches or other physical damage to the product surface, especially for precision parts with high surface treatment requirements. Any slight scratches or damage may cause the product to be scrapped.

[0006] 4. Production efficiency and consistency issues: Relying on the operator's skills and experience for manual flipping and positioning may cause fluctuations in product processing quality and affect product consistency and reliability. In addition, manual operation is inefficient, which limits production efficiency and the speed of responding to the market.

[0007] A utility model of a Chinese patent authorization publication number CN208929397U, named as a PCB board pressing and flipping double-sided welding tool, includes: a bottom plate; a fixing component, which can be flipped and arranged on the bottom plate; a receiving groove for loading the PCB board is provided on the top surface of the fixing component; a through hole is provided on the bottom surface of the fixing component; the through hole is connected to the bottom of the groove of the receiving groove; a cover plate component, which is rotatably connected to the fixing component and is located outside the notch of the receiving groove; the cover plate component can be rotated to the notch of the receiving groove to fix the PCB board in the receiving groove; an opening is provided on the cover plate component, and the opening is connected to the front area to be welded of the PCB board; a cover plate driving member, whose output end is connected to the cover plate component to drive the cover plate component to rotate and rotate the rotating driving member, whose output end is connected to the fixing component to drive the fixing component to rotate, and then the fixing component is flipped relative to the bottom plate. The PCB board only needs to be clamped once to complete the double-sided welding of the PCB board, and at the same time prevent the welding slag from splashing onto the non-welding points of the PCB board.

[0008] In the above technical solution, the PCB board pressing and flipping double-sided welding tool is specially designed for PCB boards. Although it is highly specialized, it has relatively low adaptability and is limited to the welding process of PCB boards. It may not be suitable for other types of parts or processing requirements. In addition, although the PCB board pressing and flipping double-sided welding tool also provides an automatic flipping function, the multiple cylinders and mechanical drive components involved require fine adjustment and control, which will increase the complexity of the operation and require higher skills of the operator.

[0009] Therefore, it is urgent to design a structure that can flip double-sided laser engraving while reducing costs and operating difficulty, to achieve the effect of double-sided laser engraving, and to avoid the problem of manual flipping when double-sided laser engraving is performed on the same workpiece product.

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] Embodiment 1

[0035] like Figures 1 to 3 As shown, the flip double-sided processing device includes a support 1, a rotating motor 2 is installed on the support 1, a fixture 3 is fixedly connected to the rotating shaft of the rotating motor 2, the fixture 3 has a material fixing area, a processing opening is opened on the material fixing area, a side pressure cylinder 6 is installed on one side of the fixture 3, the side pressure cylinder 6 is connected to the side pressure assembly through a flip transmission assembly, the side pressure assembly has a buffer pressing module, and the buffer pressing module is pressed on the material fixing area.

[0036] The support 1 is an L-shaped seat body, and a rotating motor 2 is installed on the vertical plate of the L-shaped seat body. The rotating shaft of the rotating motor 2 is fixedly connected to the fixture 3 through a coupling. The rotating motor 2 is started to drive the rotating shaft to rotate in a directional manner, and the fixture 3 is synchronously driven to rotate through the connection of the coupling. When the fixed material area on the fixture 3 faces upward, the top surface of the product is laser engraved; when the rotating shaft turns 180°, the fixed material area of ​​the fixture 3 faces downward, and the bottom surface of the product is laser engraved.

[0037] The material setting area is a profiling groove concavely arranged on one side of the jig 3. Avoidance grooves are arranged on both sides of the profiling groove, and the depth of the avoidance groove is greater than that of the profiling groove. The avoidance groove provides an operating space for the manipulator to take and place the product, so that the product can be accurately and quickly placed in the profiling groove. The shape of the profiling groove matches the contour of the product, so that the product can be embedded in the profiling groove to form a preliminary positioning.

[0038] At least one positioning block 4 is convexly arranged in the profiling groove, and the positioning block 4 is a cone or a trapezoid. At least one positioning hole is opened on the product, and the positioning hole is a round hole or a square hole. When the product is placed in the profiling groove, the positioning block 4 of the cone corresponds to the round hole of the product, and the positioning block 4 of the trapezoid corresponds to the square hole of the product. The structure of the cone / trapezoidal body being small at the top and large at the bottom facilitates the insertion into the positioning hole to form precise positioning.

[0039] A mounting frame 5 is arranged on one side of the fixture 3 , a slide groove is arranged on the top of the mounting frame 5 , hinge plates are symmetrically arranged on both sides of the slide groove, and a side pressure cylinder 6 is fixedly installed on the outer side surface of the mounting frame 5 .

[0040] The flip transmission assembly includes a rack 7 and a gear 8. The telescopic rod of the side pressure cylinder 6 is fixedly connected to the rack 7. The rack 7 is embedded in the slide groove to form a guide sliding connection. The center of the gear 8 is fixed through the central axis. The two ends of the central axis are correspondingly hinged on the hinge plate. The gear 8 forms a tooth meshing connection with the rack 7. The side pressure cylinder 6 drives the telescopic rod to extend, and synchronously drives the rack 7 to translate backward along the slide groove, and drives the gear 8 to rotate counterclockwise through the tooth meshing transmission. The side pressure cylinder 6 drives the telescopic rod to retract, and synchronously drives the rack 7 to translate forward along the slide groove, and drives the gear 8 to rotate clockwise through the tooth meshing transmission.

[0041] The side pressure assembly includes an L-shaped rod 9, one end of which is fixedly connected to the central axis, and the other end of the L-shaped rod 9 is connected to a pressure rod 10, which is arranged vertically with the L-shaped rod 9. When the gear 8 drives the central axis to rotate counterclockwise, the L-shaped rod 9 and the pressure rod 10 are synchronously driven to swing upward to release the product. When the gear 8 drives the central axis to rotate clockwise, the L-shaped rod 9 and the pressure rod 10 are synchronously driven to swing downward to hold the product.

[0042] The buffer pressing module includes a spring 11 and a buffer pressure head 12. A guide slide hole is opened at the other end of the L-shaped rod 9. The pressure rod 10 includes a guide slide main rod. A limit block is convexly arranged at the top end of the guide slide main rod, and a stop block is convexly arranged at the bottom end of the guide slide main rod. The guide slide main rod passes through the guide slide hole to form a sliding connection. The limit block is located above the guide slide hole, and the stop block is located below the guide slide hole. The spring 11 is sleeved on the outer periphery of the guide slide main rod, the top end of the spring 11 abuts against the L-shaped rod 9, and the bottom end of the spring 11 abuts against the table surface of the stop block. The buffer pressure head 12 is fixedly arranged at the bottom of the stop block.

[0043] The limit block is used to limit the installation of the pressure rod 10 to prevent the pressure rod 10 from falling off. The stop block provides a table surface for the pressure spring 11 to compress the spring 11. The buffer pressure head 12 is specifically a 90° silicone coating on the bottom surface of the stop block, which contacts the product surface through the silicone material to avoid crushing the product surface. When the pressure rod 10 presses the product, the pressure rod 10 is moved upward along the guide hole by the reaction force, and the spring 11 provides elastic pressure to buffer and hold the product, which can not only ensure the fixation of the product in the Z direction, but also avoid crushing the product.
