Description

Technical Field

[0001] The utility model relates to the field of laser drilling, in particular to a full-automatic four-head drilling machine. Background Art

[0002] The crystal bars in the crystal lamps need to be punched at the ends during the production process to play a connecting role during installation. Many crystal lamps are spliced ​​with crystal bars with a triangular cross-section.

This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0021] In the description of the utility model, if there is a description of quantity, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of first or second, it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] like Figures 1 to 4As shown, the utility model discloses a fully automatic four-head drilling machine, including a supporting platform 1, a feeding mechanism, a laser drilling mechanism and a product positioning mechanism, the feeding mechanism includes double-row conveyor belts 2 which are arranged in parallel at the upper end of the supporting platform 1 and run alternately, and the surfaces of the double-row conveyor belts 2 are provided with V-shaped limiting grooves 21 for limiting and fixing the products, the laser drilling mechanism includes a four-head laser module 3 fixed on the supporting platform 1 and located above one end of the double-row conveyor belt 2 and a translation mechanism capable of driving the four-head laser module 3 to reciprocate across the double-row conveyor belt 2, and the product positioning mechanism includes a first side-pushing positioning mechanism 4 and a second side-pushing positioning mechanism which are arranged on the upper end of the supporting platform 1 and are respectively located on both sides of the double-row conveyor belt 2.

[0024] During operation, the operator manually places the products to be processed in the V-shaped limit groove 21 at one end of the double-row conveyor belt 2, and then the double-row conveyor belt 2 conveys the processed products to the bottom of the laser drilling mechanism. At this time, the first side push positioning mechanism 4 and the second side push positioning mechanism will push the products from one side of the conveyor belt to the other side of the conveyor belt, thereby ensuring that the product processing position is consistent. Subsequently, the four-head laser module 3 of the laser drilling mechanism starts to perform laser drilling operations on the four groups of products on one of the conveyor belts. When the processing of this row of products is completed, the translation mechanism drives the four-head laser module 3 to translate to the top of another conveyor belt to perform laser drilling operations on the four groups of products on its conveyor belt. While this group of products is being processed, the other conveyor belt will transport the processed products to the front end, and then the unprocessed products wait for processing, thus forming alternating feeding processing, and its processing continuity is better. Moreover, the simultaneous processing by the four-head laser module 3 greatly improves the processing efficiency.

[0025] In the present invention, the product positioning mechanism further includes a first pressing positioning mechanism 5 and a second pressing positioning mechanism respectively located above the double-row conveyor belt 2. When working, after the first side-pushing positioning mechanism 4 and the second side-pushing positioning mechanism push the product sideways to position, the first pressing positioning mechanism 5 and the second pressing positioning mechanism can press the product to position it, thereby ensuring the processing stability of the product and further ensuring the processing accuracy.

[0026] In the present invention, the double-row conveyor belt 2 includes a first conveyor belt and a second conveyor belt, and a dust extraction mechanism 8 is provided between the first conveyor belt and the second conveyor belt and below the laser drilling mechanism.

By providing the dust extraction mechanism 8, the smoke and dust generated during laser drilling can be sucked and transported out through the dust extraction pipe, thereby improving the working environment of product processing and ensuring that the staff has a comfortable working environment.

[0027] In the present utility model, the first side-pushing positioning mechanism 4 includes a side-pushing support plate 42, a side-pushing driving mechanism 41 fixed on the support platform 1 and capable of driving the side-pushing support plate 42 to move forward and backward, and four groups of side-pushing ejector rods fixed on the side-pushing support plate 42, each group of the side-pushing ejector rods includes three ejector rods 43, and the second side-pushing positioning mechanism has the same structure as the first side-pushing positioning mechanism 4. The side-pushing driving mechanism 41 can be a cylinder mechanism or a linear motor module, which is used to drive the side-pushing support plate 42 to move forward and backward quickly, and each group of the four groups of side-pushing ejector rods includes three ejector rods 43, so that twelve products can be side-pushing positioned at the same time, ensuring the simultaneous processing of the four-head laser module 3, thereby ensuring the processing efficiency and processing accuracy.

[0028] In the utility model, the first downward pressing positioning mechanism 5 includes a downward pressing support plate, a downward pressing driving mechanism fixed on the support platform 1 and capable of driving the downward pressing support plate to move up and down, and four groups of downward pressing rods fixed on the downward pressing support plate, each group of the downward pressing rods includes three rods, and the second downward pressing positioning mechanism has the same structure as the first downward pressing positioning mechanism 5. The downward pressing driving mechanism can be a cylinder mechanism or a linear motor module, which is used to drive the downward pressing support plate to move up and down quickly. Each of the four groups of downward pressing rods includes three rods, so that twelve products can be pressed and positioned at the same time, ensuring the stable processing of the four-head laser module 3 at the same time. Of course, the first downward pressing positioning mechanism 5 can also be set by combining two groups, each group consisting of two groups of downward pressing rods, and its specific structure can be set according to actual conditions.

[0029] In the present invention, the first side-push positioning mechanism 4 also includes a plurality of side-push guide rods 44 provided between the side-push support plate 42 and the double-row conveyor belt 2 for guiding the movement of the side-push support plate 42, which are used for guiding the movement of the side-push support plate 42 to ensure the side-push stability.

[0030] In the present invention, the first downward pressing positioning mechanism 5 also includes a plurality of downward pressing guide rods provided between the downward pressing support plate and the support platform 1 for guiding the movement of the downward pressing support plate, so as to guide the movement of the downward pressing support plate and ensure the downward pressing stability.

[0031] In the utility model, a slot detection sensor is respectively provided on both sides of the double-row conveyor belt 2 for detecting the running condition of the conveyor belt. Once the conveyor belt is found to be offset, the operator can be prompted to perform position calibration, thereby ensuring the processing accuracy of the product.

[0032] In the utility model, the fully automatic four-head drilling machine also includes a unloading mechanism, which includes a buffer table 6 arranged on one side of the support platform 1 and located below the conveying terminal of the double-row conveyor belt 2.

[0033] In the present invention, the unloading mechanism further comprises an unloading connecting conveyor belt 7, the conveying start end of the unloading connecting conveyor belt 7 is located below the conveying terminal of the double-row conveyor belt 2, and the conveying terminal of the unloading connecting conveyor belt 7 is connected to the upper end of the unloading slope of the buffer station 6. It can facilitate the connection between the double-row conveyor belt 2 and the buffer station 6, and can also ensure that the products will not be piled up at the conveying terminal of the double-row conveyor belt 2.

[0034] The four-head laser module 3 in the utility model is four laser heads and each laser head can punch three products in sequence, so that four laser heads can punch twelve products. The four-head laser module 3 is an existing laser equipment, and its technology is very mature, so it will not be described here.

[0035] The utility model has a simple structure, and can greatly improve the punching efficiency of products by arranging double-row conveyor belts 2 for alternate feeding and four-head laser modules 3 capable of translation.
