[0045] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0046] like Figures 1 to 7 As shown, a clamping and positioning device for DCB plate welding comprises:

[0047] A clamping plate 3, wherein the number of the clamping plates 3 is multiple, and a clamping position for clamping the DCB board to be welded is formed between the multiple clamping plates 3, and at least one of the clamping positions is movably connected to the base 2;

[0048] A pressing plate 1, on which a pressing column 8 corresponding to the upper end surface of the clamping position is disposed, and a through hole 101 corresponding to the welding position of the DCB board to be welded is opened on the pressing plate 1;

[0049] Suction cup 6, the position of suction cup 6 corresponds to the lower end surface of the clamping position.

[0050] The base 2 is provided with a hand-gripping groove 201 corresponding to the clamping position, and the clamping plate 3 is provided with a notch 302 corresponding to the hand-gripping groove 201. The notch 302 and the hand-gripping groove 201 are provided to facilitate taking and placing the DCB board.

[0051] In some embodiments, there are two clamping plates 3, one clamping plate 3 is fixedly connected to the base 2, and the other clamping plate 3 is movably connected to the base 2; a flexible pad 301 is fixedly provided on the end surface of the clamping plate 3 near the clamping position, and the flexible pad 301 can prevent the clamping plate 3 from clamping the DCB board to be welded;

[0052] In other embodiments, there are four clamping plates 3 , which respectively correspond to the four side walls of the DCB board to be welded, and the four clamping plates 3 can be movably connected to the base 2 .

[0053] The clamping plate 3 movably connected to the base 2 is provided with a corresponding driving assembly:

[0054] In some embodiments, the driving component includes: a roller 4, which is rotatably connected to a connecting block 9, and the connecting block 9 is fixedly connected to a clamping plate 3; a driving block 5, which has a driving groove 501, and the bottom end of the driving groove 501 contacts the outer wall of the roller 4, and the driving groove 501 includes a first positioning portion 50101, an inclined transition portion 50102, and a second positioning portion 50103 which are connected in sequence, and the distance between the bottom end of the first positioning portion 50101 and the base 2 is greater than the distance between the bottom end of the second positioning portion 50103 and the base 2, and the bottom end of the inclined transition portion 50102 is inclined.

[0055] The bottom end of the first positioning portion 50101 is an arcuate surface matching the roller 4, the bottom end of the second positioning portion 50103 is an arcuate surface matching the roller 4, one end of the bottom end of the inclined transition portion 50102 corresponds to the bottommost end of the second positioning portion 50103, and the distance between the other end and the base 2 is greater than the distance between the bottom end of the first positioning portion 50101 and the base 2, the arcuate surface of the bottom end of the first positioning portion 50101 plays a positioning role for the roller 4, and the distance between the other end of the inclined portion and the base 2 is greater than the distance between the bottom end of the first positioning portion 50101 and the base 2, and has a certain limiting effect.

[0056] The bottom end of the driving groove 501 is arranged near the base 2; a bolt 902 is fixedly arranged on the clamping plate 3 which is movably connected to the base 2, and a mounting hole 202 arranged along the moving direction of the clamping plate 3 is opened on the base 2, and the bolt 902 is installed on the inner side of the mounting hole 202; an annular limiting boss 203 is fixedly arranged on the inner side of one end of the clamping plate 3 which is movably connected to the base 2 near the mounting hole 202, and a compression spring 903 is arranged between the annular limiting boss 203 and the bolt 902 head of the bolt 902. When the roller 4 is located at the bottom end of the first positioning portion 50101, the distance between the two clamping plates 3 is the largest. When the roller 4 is located at the bottom end of the second positioning portion 50103, the two clamping plates 3 move toward each other under the elastic force of the compression spring 903. At this time, the distance between the two clamping plates 3 is the smallest. The cylinder output shaft drives the driving block to move and controls the elongation length of the cylinder output shaft, so as to change the distance between the two clamping plates 3. When the roller 4 contacts the bottom end of the inclined transition portion 50102, the distance between the two clamping plates 3 does not reach the minimum, so the DCB plates to be welded can be aligned.

[0057] In other embodiments, the driving component is a servo electric cylinder, which is arranged along the moving direction of the clamping plate 3 , the output shaft of the servo electric cylinder is fixedly connected to the clamping plate 3 , and the body of the servo electric cylinder is fixedly connected to the base 2 .

[0058] A guide column 901 is fixedly arranged on the clamping plate 3 which is movably connected to the base 2, a guide hole 905 corresponding to the guide column 901 is opened on the base 2, a linear bearing 904 matching the guide column 901 is fixedly arranged in the guide hole 905, and the guide column 901 is installed on the inner side of the linear bearing 904. The linear bearing 904 guides the movement of the guide column 901, thereby improving the stability of the clamping plate 3 during the movement.

[0059] The clamping column 8 is a flexible member (in this embodiment, the clamping column 8 is made of rubber, and can also be made of flexible materials such as silicone). A sliding hole corresponding to the clamping column 8 is opened on the pressing plate 1. The clamping column 8 is installed on the inner side of the sliding hole. The clamping column 8 is fixedly connected to one end of the elastic plate 7, and the end of the elastic plate 7 away from the clamping column 8 is fixedly connected to the pressing plate 1 through a connecting screw 10. When the pressing plate 1 is pressed down, the clamping column 8 first contacts the upper end surface of the DCB board to be welded, and the clamping column 8 is deformed. When the pressure of the pressing plate 1 increases, the deformation of the clamping column 8 increases to the maximum. At this time, the elastic plate 7 is deformed, and the clamping column 8 moves upward to prevent the clamping from damaging the DCB board to be welded. When there are multiple clamping columns 8, through the deformation of the elastic plate 7, it can be fully guaranteed that each clamping column 8 can clamp the upper end surface of the DCB board to be welded.

[0060] A mounting groove 102 matching the elastic plate 7 is formed on the upper end surface of the pressing plate 1 . The elastic plate 7 is located inside the mounting groove 102 . The setting of the mounting groove 102 can prevent the elastic plate 7 from shaking.

[0061] The base 2 is fixed with a groove 204, and the suction cup 6 is installed inside the groove 204. The suction port of the suction cup 6 is set toward the clamping position. The suction cup 6 is a structural member made of rubber, and the suction end of the suction cup 6 protrudes from the upper end surface of the base 2. The suction cup 6 is a rubber suction cup 6. When the DCB board to be welded is placed in the clamping position, the part of the suction cup 6 protruding from the upper end surface of the base 2 is compressed, ensuring that the suction end surface of the suction cup 6 is fully fitted with the lower end surface of the DCB board to be welded.

[0062] In actual use, multiple bases 2 can be arranged as a whole array according to the production rhythm of the production line, and multiple pressing plates 1 correspond to the positions of the bases 2 to form multiple clamping stations to improve work efficiency.

[0063] Working process:

[0064] A clamping and positioning method for DCB board welding comprises the following steps:

[0065] S1, the DCB board to be welded is placed in the clamping position between two clamping plates 3;

[0066] S2, the movable clamping plate 3 moves toward the fixed clamping plate 3 to preliminarily position the DCB plate to be welded; at this time, the roller 4 is located at the bottom end of the inclined transition part, and the distance between the two clamping plates 3 has not reached the minimum.

[0067] S3, the pressing plate 1 moves toward the base 2, and after the pressing column 8 presses the upper end surface of the DCB board to be welded, the negative pressure state is activated in the suction cup 6 to adsorb the lower end surface of the DCB board to be welded, and after the DCB board to be welded is stabilized, the suction cup 6 releases the negative pressure state, and the adsorption state of the suction cup 6 is released;

[0068] S4, the movable clamping plate 3 moves toward the fixed clamping plate 3 to clamp the side of the DCB board to be welded. At this time, the roller 4 is located in the second positioning part 50103 and the clamping force is provided by the elastic force of the compression spring 903, clamping the DCB board to be welded, and starting the negative pressure state in the suction cup 6 to adsorb the lower end surface of the DCB board to be welded.

[0069] Compared with the traditional clamping and positioning device, the present application clamps the side of the DCB board to be welded by the clamping plate 3, the clamping column 8 of the pressure plate 1 presses the upper end surface of the DCB board to be welded, and the suction cup 6 adsorbs the lower end surface of the DCB board to be welded. The combined action of the three ensures the stability of the DCB board to be welded during the welding process and improves the product quality.

[0070] The clamping plate 3 is first pre-clamped and positioned, then pressed, and finally clamped with maximum force, thereby ensuring the stability of the clamping of the DCB board to be welded and the accuracy of the position of the DCB board to be welded.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
