Detailed Description

Referring to fig. 1, the thrust device for rapidly detecting a cold joint in the present embodiment mainly includes a fixture mechanism 6, a moving driving mechanism, a positioning auxiliary mechanism 5, and a thrust mechanism 1, where the fixture mechanism 6 is used to accommodate and position a product, the positioning auxiliary mechanism 5 and the thrust mechanism 1 are respectively connected to the moving driving mechanism and can move under the driving of the moving driving mechanism to detect the thrust of the product accommodated in the fixture mechanism 6, and hereinafter, each main component is illustrated with reference to the drawings.

With reference to fig. 2 and 3, in one embodiment, the fixture mechanism 6 is a product positioning fixture, the product positioning fixture is provided with a plurality of product accommodating positions, and a plurality of positioning pins 8 are further arranged at the product accommodating positions, the positioning pins 8 correspond to hole-shaped features on the products and are used for positioning the products, so that when a plurality of products are subjected to synchronous thrust detection, the positions of the products can be accurately limited to reduce errors, and detection points of different products are ensured to be the same. Furthermore, a side edge insert 9 is arranged on the side edge of the product accommodating position and used for hard limiting the side edge of the product and preventing the product from deforming in the detection process.

Referring to fig. 1 and fig. 4, the movement driving mechanism includes a first vertical driving structure 2 and a second vertical driving structure 3 which are connected, the positioning auxiliary mechanism 5 and the thrust mechanism 1 are connected with the second vertical driving structure 3, and the vertical movement is divided into two sections by the arrangement of the two vertical driving mechanisms, so that the impact on the product and the clamp mechanism 6 when the vertical driving mechanism is lifted can be reduced. For example, in one embodiment, the movement driving mechanism includes a first cylinder and a second cylinder vertically disposed, the telescopic end of the first cylinder is connected to the second cylinder, and the telescopic end of the second cylinder is connected to a connecting bracket for connecting the positioning assisting mechanism 5 and the thrust mechanism 1.

The positioning auxiliary mechanism 5 comprises a floating press block 12, and the floating press block 12 is used for abutting against the upper side of the clamp mechanism 6 so as to prevent the product from moving upwards due to deflection force when thrust is applied to the product, so that the product is prevented from deforming and is mistakenly judged to be a false welding. In one embodiment, the floating pressing block 12 includes a pressing portion and a floating spring 11, the pressing portion is connected to the lower side of the moving driving mechanism, for example, the lower side of the connecting bracket, through the floating spring 11, so that when the moving driving mechanism drives the pressing portion to move to the upper side position of the clamping mechanism 6 and continues to press down, the pressing portion can be abutted to the upper side of the clamping mechanism 6 through the elastic force of the floating spring 11 to prevent the product from moving upwards.

The pushing mechanism 1 is used for detecting pushing force, is arranged in pairs and corresponds to the product accommodating position of the clamp mechanism 6, and is used for providing pushing force for the product to detect. For example, the thrust mechanism 1 includes opposite thrust members 10, and the opposite thrust members 10 are respectively connected to the thrust driving mechanism 4 and can move toward and away from each other under the driving of the thrust driving mechanism 4. In one embodiment, the thrust member 10 comprises a probe 15, a thrust spring 14 and a thrust sensor 13 which are connected in sequence, the probe 15 and the thrust sensor 13 are connected through the thrust spring 14, so that when the thrust member 10 applies acting force to a product under the pushing of the thrust driving mechanism 4, the force value of the reaction force received by the probe 15 is transmitted to the thrust sensor 13 through the spring, and therefore corresponding thrust detection can be carried out.

In a preferred embodiment, the pushing mechanism 1 further comprises a push rod 16 oppositely disposed on both sides of the positioning assisting mechanism 5, for example, a push rod connecting bracket is disposed on a connecting bracket at the bottom of the vertical driving mechanism, the push rod connecting bracket is disposed on both sides of the positioning assisting mechanism 5, and the push rod 16 is movably connected to the push rod connecting bracket. The push rod 16 and the thrust component 10 are arranged correspondingly, the inner end of the push rod 16 is provided with a push head 17, and when the thrust component 10 moves under the driving of the thrust driving mechanism 4, the push rod 16 which is arranged oppositely can be driven to move, so that the thrust is detected. When the floating spring 11 is not compressed by force, the pressing portion is located between the push rods 16, so that the push rods 16 cannot be pushed. When the floating pressing block 12 is pressed down to a proper position under the driving of the movement driving mechanism, the pressing part overcomes the elastic force of the floating spring 11 to move upwards, so that the pressing part is no longer positioned between the push rods 16 which are arranged oppositely, and the push rods 16 can be pushed by the thrust part 10 to detect the thrust.

In one embodiment, eight product containing positions are arranged on the product positioning fixture, eight groups of thrust components 10 and eight groups of push rods 16 are correspondingly arranged, the number of the thrust cylinders is two, namely the left thrust cylinder and the right thrust cylinder, each thrust cylinder controls eight push heads 17, and the strokes of the eight push heads 17 are the same, so that the thrust error of each push head 17 is reduced. When the device is used, the first cylinder firstly extends out to press down the whole structure, then the second cylinder pushes the positioning auxiliary mechanism 5 and the thrust mechanism 1 to be close to the product positioning clamp, the floating pressing block 12 presses the product and retracts due to stress, and the limit of the pushing head 17 is released. The thrust cylinders on the two sides drive the thrust component 10 to apply thrust to the welding elastic sheet of the product, the push head 17 can drive the push rod 16 to contract backwards due to the blocking of the elastic sheet, the contracted push head can support the thrust spring 14 of the probe 15, and the compression force of the thrust spring 14 is applied to the thrust sensor 13. The pressure transmitted back to the controller by the thrust sensor 13 is used for judging whether the cold joint exists or whether the shrapnel exists.

The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
