The invention discloses a linear boring tool capable of achieving variable feeding cutting. A linear boring tool outer tool body, a linear boring tool inner pull rod and a turning displacement block are included. The linear boring tool inner pull rod is sleeved with the linear boring tool outer tool body. The circumferential face of the linear boring tool outer tool body is provided with a matching groove in which the turning displacement block is inserted. The turning displacement block is provided with an arc groove. The linear boring tool inner pull rod is provided with a boss capable of sliding in the arc groove and driving the turning displacement block to move in the radial direction of the linear boring tool outer tool body. The part, protruding out of the matching groove, of the turning displacement block is provided with two symmetrically-arranged turning blades. The circle center of the arc groove and the turning blades are located on the same side. During bent shaft hole third thrust face turning through the linear boring tool, turning feeding becomes high from low and conforms to the specific curvature change, tool breakage at the cutting-in moment during turning is prevented, the performance of the turning blades is improved, the service life of the turning blades is prolonged, and the surface quality of the third thrust face turned by the linear boring tool is improved.

The invention provides an obstacle avoidance spraying robot. The obstacle avoidance spraying robot comprises a base (2), a waist portion (3), a big arm (4), a middle arm (5), a small arm (6), a wrist portion (7), a hand portion (8) and a tail end (9). The rotating axis, relative to the small arm (6), of the wrist portion (7), the rotating axis, relative to the wrist portion (7), of the hand portion (8) and the rotating axis, relative to the hand portion (8), of the tail end (9) are pairwise orthogonal and intersect with one another at one point. The upper end of the middle arm (5) can also rotate relative to the lower end of the middle arm (5). A spray gun (1) is mounted at the tail end (9). The obstacle avoidance spraying robot can bypass obstacles horizontally arranged and obstacles vertically arranged, has the obstacle avoidance function and meanwhile can avoid blocking of the spray gun (1) effectively.

The invention relates to a matching die cutting and half-and-half rotating pasting processing method for conductive adhesive. The matching die cutting and half-and-half rotating pasting processing method for the conductive adhesive includes the following steps of 1, typesetting and designing; 2, die cutting mode designing; 3, waste scheme designing; 4, product rotating pasting. After die cutting is performed on a single product, the half-and-half rotating pasting technology is adopted. The half-and-half rotating pasting technology comprises the steps that a row of products are pasted in a rotating mode, after material strips are cut, and the other half products are reposted; two strips of box sealing tape with the width of 5 mm are needed in product rotating pasting, a single PCS product is firstly fixed, dislocation or amount missing are prevented, then face paper on the conducting adhesive is removed, the original two rows of side-by-side products which are designed through the up-down and front-back rope winding are changed into products by rotating pasting in sequence and material strap cutting in sequence, therefore, the typesetting of a client is restored, and products the customer needed are manufactured. The matching die cutting and half-and-half rotating pasting processing method for the conductive adhesive improves the use efficiency of conducting resin materials, the waste materials in the manufacturing process are eliminated, the blade collapse is prevented, the normal production is guaranteed, and the production efficiency is improved; the conducting resin product rotating pasting is achieved, and the product typesetting is restored.
