When the supporting plate 103 is in a horizontal state, a concave groove matched with the positioning plate 75 is formed between the notch 101 and the notch 101, so that the positioning plate 75 can just pass through the concave groove.

[0034] In the above scheme: when the top seat 4 moves downward, the top seat 4 drives the limit shaft 7 to move downward, the limit shaft 7 drives the first rack 71 to move downward, and the first rack 71 drives the first gear 73 meshing with it to rotate clockwise. Since the first gear 73 is meshed with the rack plate 74 on the positioning plate 75, the first gear 73 will drive the positioning plate 75 to move upward when it rotates clockwise, so that the upper side of the positioning plate 75 extends from the slot 101 on the detection table 1, so as to position the pressed conductive foam and prevent it from being offset during pressing.

[0035] For further information, see Figure 1 In the embodiment of the present invention, a pressing hydraulic cylinder 5 is installed on the upper part of the top seat 4. The output shaft of the pressing hydraulic cylinder 5 is located at the lower position of the top seat 4 and is connected to a pressing plate 6 for pressing the conductive foam.

When the positioning plate 75 is displaced, the limiting sleeve 76 will slide on the fixed shaft 77 to guide the positioning plate 75.

[0037] The second embodiment is different from the first embodiment in that:

[0038] See also Figure 4 and Figure 5In the embodiment of the present invention, a strip plate 78 is provided at the inner lower edge of the positioning plate 75, and a top shaft 79 is vertically connected to the upper part of one end of the strip plate 78, and a rubber head 710 is connected to the upper end of the top shaft 79. A limiting groove 104 corresponding to the rubber head 710 is provided at the bottom of the bearing plate 103. When the output shaft of the lifting hydraulic cylinder 3 is extended, the positioning plate 75 is located in the detection platform 1. When the output shaft of the lifting hydraulic cylinder 3 is shortened, the lower end of the limiting shaft 7 is just in contact with the upper part of the detection platform 1. The upper side of the positioning plate 75 extends from the concave groove between the supporting plate 103 and the notch 101, and the rubber head 710 at the upper end of the top shaft 79 just pushes the supporting plate 103 to a horizontal state, and one side of the conveyor belt 10 is located at the outer side of the positioning plate 75. When the supporting plate 103 is in a reset state, the side of the supporting plate 103 away from the torsion spring 102 is located at the upper side of the positioning plate 75, so that the conductive foam on the supporting plate 103 can just slide onto the conveyor belt 10.

[0039] In the above scheme: during the rising process of the positioning plate 75, the top shaft 79 will be driven to rise, and the top shaft 79 will gradually approach the direction of the bearing plate 103 and extend into the limiting groove 104 at the bottom of the bearing plate 103. As the positioning plate 75 continues to rise, under the elasticity of the torsion spring 102, the rubber head 710 at the upper end of the top shaft 79 will push the bearing plate 103 to rotate upward. When the lower end of the limiting shaft 7 contacts the upper part of the detection platform 1, the bearing plate 103 is just pushed to a horizontal state, so that the conductive foam can be placed flat on the bearing plate 103, which is convenient for pressing the conductive foam. After the pressing is completed, the lifting hydraulic cylinder 3 drives the top seat 4 moves up, the top seat 4 drives the limiting shaft 7 to move up, the limiting shaft 7 drives the first rack 71 to move up, the first rack 71 makes the first gear 73 rotate counterclockwise, so that the positioning plate 75 moves down, and as the positioning plate 75 moves down, the rubber head 710 at the upper end of the top shaft 79 gradually leaves the limiting groove 104 at the bottom of the carrier plate 103, and under the elasticity of the torsion spring 102, the carrier plate 103 will be reset to be in a tilted state, and the positioning plate 75 will move into the detection table 1, and the conductive foam on the tilted carrier plate 103 will slide onto the conveyor belt 10, and the conveyor belt 10 will transport the pressed conductive foam to the next station.

[0041] Embodiment 3 is different from Embodiment 1 in that:

[0042] See also Figure 1 In the embodiment of the present invention, a storage box 2 for storing conductive foam is provided on the upper part of the side of the detection platform 1 away from the conveyor belt 10. The length and width of the interior of the storage box 2 are equal to the length and width of the conductive foam. The storage box 2 is located on one side of the slot 101, and through slots 9 that can just accommodate the conductive foam are provided at the bottom of both sides of the storage box 2. The internal width of the positioning plate 75 is equal to the length of the through slot 9.

[0043] See also Figure 1-Figure 3 In the embodiment of the present invention, the automatic pressing device for conductive foam also includes a feeding mechanism 8 for feeding the conductive foam, the feeding mechanism 8 includes two guide shafts 81 arranged on the side of the detection platform 1 away from the conveyor belt 10, and a guide plate 82 is provided between the outer parts of the two guide shafts 81 for transverse sliding. A push plate 83 corresponding to the through slot 9 is provided on the upper side of the guide plate 82, so that the push plate 83 can just pass through the through slot 9. The feeding mechanism 8 also includes an L-shaped rod 85 arranged on one side of the top seat 4 and a mounting plate 84 at the edge of the side of the detection platform 1 away from the conveyor belt 10. A second gear 87 is rotatably provided on a side of the mounting plate 84 away from the push plate 83, and a second rack 86 is provided on one side of the L-shaped rod 85. The second rack 86 is meshed with the second gear 87. One end of the second gear 87 is located at the other side of the mounting plate 84 and is connected to a displacement driving component 88 for driving the push plate 83 to move laterally.

[0044] In the above scheme: the conductive foam to be pressed is placed in the storage box 2, and then the lifting hydraulic cylinder 3 drives the top seat 4 to move downward, and the top seat 4 will drive the L-shaped rod 85 to move downward, and the second rack 86 on the L-shaped rod 85 will drive the second gear 87 meshing with it to rotate, and the second gear 87 will drive the displacement drive component 88 to work, and the displacement drive component 88 drives the push plate 83 to push in the direction of the storage box 2, and move to the through slot 9 on the storage box 2, and push out the bottom conductive foam in the storage box 2, and the second to last conductive foam will be pressed on the upper side of the push plate 83, so that the conductive foam is pushed out. When the top seat 4 moves downward to the position of the carrier plate 103, when the top seat 4 moves downward to the lower end of the limit shaft 7 and contacts the upper part of the detection platform 1, the push plate 83 just pushes the conductive foam to the specified position, stops the work of the lifting hydraulic cylinder 3, and completes the feeding operation of the conductive foam. When the lifting hydraulic cylinder 3 drives the top seat 4 to move upward, it will drive the L-shaped rod 85 to move upward, so that the push plate 83 can move to the initial position. When one side of the push plate 83 leaves the interior of the storage box 2, the next conductive foam in the storage box 2 will fall to the bottom, and then repeat the above steps to continuously feed the conductive foam. Figure 7-Figure 8 shown.

[0045] For further information, see Figure 2 and Figure 3 In the embodiment of the present invention, the displacement driving assembly 88 includes a turntable 881 connected to one end of the second gear 87, and an eccentric shaft 882 is arranged at the edge of one side of the turntable 881 away from the mounting plate 84. The outer longitudinal sliding sleeve of the eccentric shaft 882 is provided with a grooved strip plate 883, and a limiting rod 884 is connected to one side of the upper end of the grooved strip plate 883. The limiting rod 884 is connected to one side of the push plate 83. The second gear 87 will drive the turntable 881 to rotate, and the turntable 881 will drive the eccentric shaft 882 to make an eccentric movement. The eccentric shaft 882 will drive the grooved strip plate 883 to approach the direction of the detection platform 1, so that the limiting rod 884 on the grooved strip plate 883 drives the push plate 83 to push toward the storage box 2.

[0046] For further information, see Figure 2 and Figure 3 In the embodiment of the present invention, guide grooves 841 are provided on the upper and lower sides of the mounting plate 84, and guide blocks 8831 are provided at both ends of the grooved strip plate 883. One end of the guide block 8831 is provided in the guide groove 841 and is horizontally slidably connected with the mounting plate 84. When the grooved strip plate 883 moves, the guide block 8831 will slide in the guide groove 841, thereby guiding the grooved strip plate 883.

[0047] For further information, see Figure 2 and Figure 3In the embodiment of the present invention, when the output shaft of the lifting hydraulic cylinder 3 is extended, the side of the push plate 83 away from the guide plate 82 just leaves the through groove 9 on the storage box 2. After the output shaft of the lifting hydraulic cylinder 3 is shortened, the side of the push plate 83 away from the guide plate 82 just pushes out the bottom conductive foam in the storage box 2 and presses against the inner side of the positioning plate 75.

[0048] Working principle: put the conductive foam to be pressed into the storage box 2, and then the lifting hydraulic cylinder 3 drives the top seat 4 to move downward, and the top seat 4 will drive the L-shaped rod 85 to move downward, and the second rack 86 on the L-shaped rod 85 will drive the second gear 87 meshing with it to rotate, and the second gear 87 will drive the turntable 881 to rotate, and the turntable 881 will drive the eccentric shaft 882 to make an eccentric movement, and the eccentric shaft 882 will drive the grooved strip plate 883 to approach the direction of the detection table 1, so that the limit rod 884 on the grooved strip plate 883 drives the push plate 83 to push in the direction of the storage box 2, and move it to the through slot 9 on the storage box 2, and push out the bottom conductive foam in the storage box 2. The penultimate conductive foam will press on the upper side of the push plate 83, so that the conductive foam is pushed to the position of the carrier plate 103. When the top seat 4 moves down to the lower end of the limit shaft 7 and contacts the upper part of the detection table 1, the push plate 83 just pushes the conductive foam to the specified position, stops the work of the lifting hydraulic cylinder 3, and completes the feeding operation of the conductive foam. When the lifting hydraulic cylinder 3 drives the top seat 4 to move up, it will drive the L-shaped rod 85 to move up, so that the push plate 83 can move to the initial position. When one side of the push plate 83 leaves the interior of the storage box 2, the next conductive foam in the storage box 2 will fall to the bottom, and then repeat the above steps to continuously feed the conductive foam.

[0049] When the top seat 4 moves downward, the top seat 4 drives the limiting shaft 7 to move downward, the limiting shaft 7 drives the first rack 71 to move downward, and the first rack 71 drives the first gear 73 meshing with it to rotate clockwise. Since the first gear 73 is meshed with the rack plate 74 on the positioning plate 75, the first gear 73 will drive the positioning plate 75 to move upward when it rotates clockwise, so that the upper side of the positioning plate 75 extends from the notch 101 on the detection table 1, and the pressed conductive foam is positioned so that it is not easy to deviate during pressing. When the lower end of the positioning plate 7 contacts the upper part of the testing platform 1, the push plate 83 just pushes the conductive foam against the inner side of the positioning plate 75, which plays a role in positioning the conductive foam. During the rising of the positioning plate 75 and the pushing of the conductive foam, the conductive foam is always located inside the positioning plate 75, which limits the conductive foam and prevents the conductive foam from shifting. Then, the pressing hydraulic cylinder 5 drives the pressing plate 6 to move downward, and the pressing plate 6 presses the conductive foam. The pressing force of the conductive foam is determined by the pressure sensor at the bottom of the pressing plate 6.

[0050] As the positioning plate 75 rises, the top shaft 79 will be driven to rise, and the top shaft 79 will gradually approach the direction of the carrier plate 103 and extend into the limiting groove 104 at the bottom of the carrier plate 103. As the positioning plate 75 continues to rise, under the elasticity of the torsion spring 102, the rubber head 710 at the upper end of the top shaft 79 will push the carrier plate 103 to rotate upward. When the lower end of the limiting shaft 7 contacts the upper part of the detection platform 1, the carrier plate 103 is just pushed to a horizontal state, so that the conductive foam can be placed flat on the carrier plate 103, which is convenient for pressing the conductive foam. After the pressing is completed, the lifting hydraulic cylinder 3 drives the top seat 4 to move upward. , the top seat 4 drives the limiting shaft 7 to move upward, the limiting shaft 7 drives the first rack 71 to move upward, the first rack 71 makes the first gear 73 rotate counterclockwise, so that the positioning plate 75 moves downward, and as the positioning plate 75 moves downward, the rubber head 710 at the upper end of the top shaft 79 gradually leaves the limiting groove 104 at the bottom of the supporting plate 103, and under the elasticity of the torsion spring 102, the supporting plate 103 will be reset to be in an inclined state, and the positioning plate 75 will move into the detection table 1, and the conductive foam on the tilted supporting plate 103 will slide onto the conveyor belt 10, and the conveyor belt 10 will transport the pressed conductive foam to the next station.
