Detailed Description

The following describes specific embodiments of the present utility model with reference to the drawings.

As shown in fig. 1 and 2, the online storage type feeding projection welding workstation of the embodiment comprises a combined feeding frame 1, a carrying robot 2 is arranged by taking the combined feeding frame 1 as a reference, a marking machine 4 and a material storage table 3 are sequentially arranged on the moving path of the carrying robot 2, a welding robot 5 is arranged on the side edge of the material storage table 3, a nut machine, a projection welding machine 6 and a detection station 7 are arranged on the moving path of the welding robot 5, the output end of the detection station 7 is connected with a defective product box 8 and a good product conveying belt 9,

The combined feeding frames 1 comprise at least two groups, each group of feeding frames 1 is slidably provided with at least two groups, and in the working process, each group of feeding frames 1 is located in the grabbing range of the carrying robot 2.

The workstation is provided with the rail, and the rail is used as the installation benchmark to go up work or material rest 1, and two extreme motion positions of same group material rest 1 are in the inside and outside bilateral symmetry setting of rail.

The same group of feeding frames 1 are staggered in vertical height.

Each group of feeding frames 1 is provided with two groups of sliding rails 105 in the vertical direction, each sliding rail 105 corresponds to one feeding frame 1, and the feeding frames 1 are mutually independent or slide in a linkage way.

The conveying robot 2 is provided with a material storage table 3 and a marking machine 4 along a counterclockwise direction along a movement path.

On the motion path of the welding robot 5, a nut machine, a projection welding machine 6 and a detection station 7 are arranged in the clockwise direction. The nut machine is used for conveying the nuts to be used to the electrode for welding after detection, and is a commercially available piece, and details are omitted in this embodiment.

The output end of the conveyor belt 9 is located outside the pen.

The welding robot 5 and the transfer robot 2 are respectively positioned at adjacent sides of the material storage table 3.

The concrete structure and the working process of the utility model are as follows:

As shown in fig. 1, the utility model provides a projection welding workstation, which has the main advantages that a storage type feeding frame 1 is adopted, and continuous and alternate feeding can be realized.

As oriented in fig. 1, the workstation is provided with four feeding frames 1 distributed in a rectangular shape, and every two feeding frames 1 are in a group. A transfer robot 2 is arranged between the two groups of feeding frames 1, one side, away from the feeding frames 1, of the transfer robot 2 is provided with a material storage table 3, and products on the feeding frames 1 are grabbed by the transfer robot 2 and then are sent to the material storage table 3.

The feeding rack 1 is characterized in that two groups of feeding racks 1 are arranged, each group is provided with one feeding rack 1 positioned outside a fence of a workstation, so that operators or robots can put products to be processed on the feeding racks 1 in batches. Another of the same group is known to be located within the workstation's pen. The two feeding frames 1 of the same group are arranged on the same slide rail 105, and the relative position conversion of the feeding frames 1 of the same group is realized through sliding on the slide rail 105. In order to be able to support the fully loaded loading ledges 1, three slide rails 105 are evenly arranged at the bottom of each loading ledge.

For example, in the initial state, both feeding racks 1 are empty, one feeding rack 1 is inside the rail and the other feeding rack 1 is outside the rail. After the loading frame 1 outside the fence is fully loaded with products, the products slide into the fence, and at the moment, the carrying robot 2 can grab the products fully loaded on the loading frame 1. The loading frame 1 in the rail originally slides out of the rail, the empty loading frame 1 can be continuously loaded, and when the full loading frame 1 is carried by the carrying robot 2, the loading frame slides out of the rail, and the empty loading and full loading material taking processes are repeated.

In order to facilitate the reciprocating sliding switching of the same group of feeding frames 1, the utility model provides the upper and lower double-layer sliding rails 105, and the vertical height interval between the double-layer sliding rails 105 allows the full-load feeding frames 1 to slide smoothly, so that the products to be prepared are not easy to collide.

In order to improve the working efficiency, two groups of four feeding frames 1 are sequentially fed. Taking two groups of feeding frames 1 as an example, according to the azimuth in the figure, the feeding frame 1 at the upper left corner is made to be a first feeding frame 1011, the feeding frame 1 at the lower left corner is made to be a second feeding frame 1021, the feeding frame 1 at the upper right corner is made to be a third feeding frame 1031, and the feeding frame 1 at the lower right corner is made to be a fourth feeding frame 1041. When the automatic feeding device is used, as an available grabbing sequence, products on the first feeding frame 1011 are grabbed firstly, after grabbing, products on the third feeding frame 1031 are grabbed again, namely full-load feeding frames 1 which are already sent into the fence are grabbed sequentially, then the full-load feeding frames 1 which are already grabbed are pushed and pulled manually, and a second feeding frame outside the fence is sent into the fence to wait for grabbing again. The operation mode has the advantage of providing sufficient operation time for feeding and sliding. If there are more groups of loading ledges 1, the sequential gripping can also be performed in this order.

After grabbing the product, the carrying robot 2 sends the product to the marking machine 4 for marking, and after marking, the product is placed on the material storage table 3 for fine positioning. The special positioning clamp is arranged on the material storage table 3, the contour shape is made according to the product, for example, a stamping plate is adopted by the positioning clamp, and the purpose of accurate positioning is achieved by adopting the bulge with the same contour as the stamping plate.

After positioning, the welding robot 5 is used for grabbing and then sending the welding robot to the projection welding machine 6 for welding. The projection welding machine 6 adopts commercial parts, and the welding is a conventional technical means, and is not described in detail in this embodiment.

The welded product is carried to the detection station 7 by the welding robot 5 for detection, the detection equipment adopts commercial parts, defective products are detected, the defective product boxes 8 are discarded, and the products are placed outside the output rail on the conveying belt 9 after being detected to be qualified and are collected manually.

The technical key point of the utility model is the specificity of the feeding mechanism. The material loading structure in this scheme adopts multiunit material loading frame 1, and each group material loading frame 1 can switch two material loading frames 1 of full load, no-load, and the combined use of multiunit material loading frame 1 can guarantee to last to wait to snatch the part in the rail, ensures production beat.

The above description is intended to illustrate the utility model and not to limit it, the scope of which is defined by the claims, and any modifications can be made within the scope of the utility model.
