Description

Technical Field

[0001] This utility model relates to the field of sheet metal parts technology for household appliances. More specifically, this utility model relates to a laser marking and positioning fixture for stamped parts. Background Technology

[0002] During the assembly of air conditioners, to prevent the mixing of critical components, certain stamped parts of each model are required to have QR codes printed using laser marking to match the overall unit's coding, thus preventing errors. Because laser marking requires high perpendicularity, poor positioning can easily lead to various marking defects. This is mainly because during laser marking, some parts may have recesses, causing deviations in perpendicularity with the marking machine, resulting in inconsistent laser focal lengths and thus defects in the QR codes on the stamped parts. This affects product quality and efficiency, and also takes a long time to position the parts. Therefore, to solve the problem of consistent perpendicularity during laser marking and to shorten the placement and retrieval time for each product, a laser marking positioning fixture for stamped parts needs to be designed to meet practical requirements. Utility Model Content

[0003] One objective of this invention is to provide a laser marking and positioning fixture for stamped parts, which ensures the consistency of verticality during the laser marking process, shortens the time for placing and picking up each product, and improves the product qualification rate and production efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides a laser marking and positioning fixture for stamped parts, including a worktable and a base set on the worktable. The base is provided with a slider and has a recess. When the product is placed on the base, the bottom of the product is exactly located in the recess. The base is also provided with a baffle that abuts against the rear side of the product from the rear. The base is also provided with a pair of push rods and a pair of positioning plates. Each of the positioning plates is provided with a through hole. The pair of positioning plates are arranged on the base with a gap between them. The pair of push rods pass through the through holes of the pair of positioning plates. Each of the push rods is provided with an adjusting plate and a spring on the side near the baffle. The spring is sleeved on the push rod and its two ends abut against the adjusting plate and the positioning plate respectively. The ends of the pair of push rods abut against the front side of the product.

[0005] Preferably, the base has a transverse sliding groove along its upper edge, and the bottom of the baffle slides precisely within the transverse sliding groove. The base also has two longitudinal sliding grooves along its upper edge, and the slider and a pair of positioning plates slide precisely within the two longitudinal sliding grooves respectively.

[0006] Preferably, the bottom of the baffle, slider and a pair of positioning plates are provided with threaded holes, and after sliding to the set position, they are fixed by bolts.

[0007] Preferably, the cross-sections of the transverse slide and the two longitudinal slides are trapezoidal.

[0008] Preferably, each of the pair of positioning plates has a number of through holes arranged in a one-to-one correspondence along its longitudinal direction.

[0009] Preferably, the pair of push rods are L-shaped and the longitudinal ends are threaded rods. The longitudinal ends of the pair of push rods have opposite thread directions and are connected as one unit by a connecting pipe with internal threads, so that when the connecting pipe is rotated, the pair of push rods are relatively close to or far apart.

[0010] Preferably, the lateral ends of the pair of push rods are also provided with threaded rods, and the adjusting plate is threaded onto the threaded rods.

[0011] Preferably, both the adjusting plate and the positioning plate are provided with blind holes for fixing the ends of the spring.

[0012] Preferably, the end of the push rod that abuts against the product is provided with a contact block larger than the push rod.

[0013] Preferably, the workbench has several threaded holes arranged in a crisscross pattern, and the base has multiple threaded holes, which are connected to the workbench by bolts; the workbench is fixed to the base plate, and the laser marking machine is also fixed to the base plate, with its laser emitter head facing directly above the product.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. This utility model uses a slider to shorten the product positioning and placement time; the original product laser marking and placement time was 15 seconds, while the laser marking and placement time is 6 seconds after using the new tooling of this application, thus improving production efficiency.

[0016] 2. The addition of recesses to the slider and the fastening via push rods in this utility model greatly improves the perpendicularity between the product and the marking machine, ensuring consistent perpendicularity during laser marking. The original product QR code marking defect rate was 3%, while the defect rate after using the new tooling of this application is 0.1‰. This improves the laser marking yield, increases the product QR code qualification rate, and ensures accurate positioning of each product.

[0017] 3. This utility model allows for the movable combination of various tooling components through the sliding groove. Similar products with different marking positions can share the same components, increasing the degree of freedom and making it more widely adaptable to a wider range of products, thus saving costs.

[0018] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0026] To better understand the purpose, structure, and function of this utility model, the following detailed description is provided in conjunction with the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0027] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this application, the horizontal direction refers to the Y-axis, and the vertical direction refers to the X-axis.

[0029] like Figures 1 to 5As shown, this utility model provides a laser marking and positioning fixture for stamped parts, including a worktable 1 and a base 2 disposed on the worktable 1. The base 2 is provided with a slider 4, which has a recess 11. When the product 10 is placed on the base 2, the bottom of the product 10 is located in the recess 11. The base 2 is also provided with a baffle 3, which abuts against the rear side of the product 10 from the rear. The base 2 is also provided with a pair of push rods 5 and a pair of positioning plates 7. Each of the pair of positioning plates 7 is provided with a through hole 13. The pair of positioning plates 7 are disposed on the base 2 at intervals. The pair of push rods 5 pass through the through holes 13 of the pair of positioning plates 7. Each of the pair of push rods 5 is provided with an adjusting plate 14 and a spring 6 on the side of the pair of push rods near the baffle 3. The spring 6 is sleeved on the push rod 5 and its two ends abut against the adjusting plate 14 and the positioning plate 7 respectively. The ends of the pair of push rods 5 abut against the front side of the product 10.

[0030] By placing the countersunk plate 16 of the marking area of ​​product 10 into the slider 4, product 10 is positioned. The push rod 5, spring 6, and baffle 3 ensure product 10 remains stable and does not shift, guaranteeing consistent perpendicularity during laser marking. In use, as shown in the attached diagram, pull the push rod 5 along the Y-direction through hole 13 (spring 6 is compressed at this time). There is a large gap between the end of the push rod 5 and product 10. Place product 10 into the fixture along the X-direction, against the baffle 3, and position the countersunk plate 16 of product 10 in the recess 11 of the slider 4. This ensures the perpendicularity of the countersunk plate 16 to the laser marking machine 9. Then, return the push rod 5 to its original position. The spring 6's compression and rebound force holds the push rod 5 against product 10, ensuring product 10 is stable in the fixture. After the marking process is complete, pull the push rod 5 again, remove product 10, and place a new product 10 inside.

[0031] In another technical solution, the base 2 is provided with a transverse sliding groove 12 along the horizontal direction, and the bottom of the baffle 3 slides in the transverse sliding groove 12. The base 2 is provided with two longitudinal sliding grooves 12 along the vertical direction, and the slider 4 and a pair of positioning plates 7 slide in the two longitudinal sliding grooves 12 respectively.

[0032] The slider 4 is slidably positioned via the longitudinal groove 12, shortening the positioning time of the product 10. The transverse groove 12 allows the baffle 3 to also move, enabling flexible adjustment based on the position and type of the product 10, thus stabilizing its position. Another longitudinal groove 12, also fitted with a pair of positioning plates 7, allows the positioning plates 7 to move, thereby adjusting the position of the push rod 5 to match the position of the product 10. Three grooves 12 are designed on the base 2, allowing the baffle 3, slider 4, and positioning plates 7 to move. The baffle 3 can move along the Y direction (approximately 30 mm); the slider 4 can move along the X direction (approximately 120 mm); and the positioning plates 7 can move along the X direction (approximately 65 mm). Furthermore, when changing to different products 10, the baffle 3, slider 4, push rod 5, and positioning plates 7 can be moved in their respective directions to accommodate the tooling positioning of other similar products 10.

[0033] In another technical solution, the bottom of the baffle 3, slider 4, and a pair of positioning plates 7 are all provided with threaded holes, and after sliding to the set position, they are fixed by bolts. The base 2 has a countersunk hole in the slide groove 12, and the bottom of the baffle 3, slider 4, and pair of positioning plates 7 have threaded holes, which are fixed by hexagonal socket head cap screws. Although the bottom of the baffle 3, slider 4, and pair of positioning plates 7 can be moved for different products, in actual operation, to prevent the baffle 3, slider 4, and pair of positioning plates 7 from moving, they are locked with bolts.

[0034] In another technical solution, the cross-sections of the transverse slide 12 and the two longitudinal slides 12 are all trapezoidal structures, which realizes stable engagement and sliding and avoids derailment.

[0035] In another technical solution, a pair of positioning plates 7 are each provided with a number of through holes 13 in a one-to-one correspondence along their longitudinal direction. In one embodiment, the push rod 5 can be installed in 7 holes in the Z direction of the positioning plate of the push rod 5 (travel of about 60 mm) to accommodate the positioning of more products 10.

[0036] In another technical solution, a pair of push rods 5 are L-shaped and their longitudinal ends are threaded rods. The longitudinal ends of the pair of push rods 5 have opposite thread directions and are connected as one unit by a connecting pipe 8 with internal threads. This allows the pair of push rods 5 to move closer or further apart when the connecting pipe 8 is rotated, thereby adjusting the distance between the pair of push rods 5. The stroke is about 40 mm to accommodate the positioning of more different products 10.

[0037] In another technical solution, the lateral ends of a pair of push rods 5 are also configured as threaded rods, and the adjusting plate 14 is threaded onto the threaded rods. The push rods 5 are threaded and can also move in the Y direction (stroke of about 40 mm). When changing to different products 10, the baffle 3, slider 4S, push rods 5, and push rod 5 positioning plate 7 can be moved in their respective directions to conform to the tooling positioning of other similar products 10.

[0038] In another technical solution, both the adjusting plate 14 and the positioning plate 7 are provided with blind holes, which are used to fix the end of the spring 6, so that the spring 6 is stable and the elastic force acts in the Y direction.

[0039] In another technical solution, the end of the push rod 5 that abuts against the product 10 is provided with a contact block larger than the push rod 5, resulting in a larger contact area and more stable positioning.

[0040] In another technical solution, the worktable 1 has several threaded holes arranged in a crisscross pattern, and the base 2 has multiple threaded holes, which are bolted to the worktable 1. The worktable 1 is fixed to the base plate 15, and the laser marking machine 9 is also fixed to the base plate 15, with its laser emitter head directly above the product 10. Four hexagon socket head cap screws are fastened to the worktable 1 through the countersunk threaded holes on the base 2, and the fixing position can be flexibly adjusted according to the position of the laser marking machine 9.
