[0012] An assembly method for the above-mentioned automatic assembly equipment for strip materials includes the following steps:

[0013] Step 1: Flip over the flipping and pushing components A and B to the side away from the loading station;

[0014] Step 2: Place the middle strip material, the loading fixture, and the side strip material into the designated positions at the loading station;

[0015] Step 3: Flip push component A and flip push component B back to their initial positions;

[0016] Step 4: When the side frame, as incoming material, is conveyed to the designated position, the cylinder of the side frame positioning component actuates, fixing the side frame on the incoming material conveyor line;

[0017] Step 5: The drive mechanism of the lifting component is activated, and the lifting frame drives the pressing component, clamping component, flipping and pushing component A, flipping and pushing component B, blocking and positioning mechanism and side frame positioning component to descend to the designated position;

[0018] Step 6: The clamping drive cylinder of the clamping assembly actuates, driving the sliding clamping seat to the designated position of the fixed clamping seat;

[0019] Step 7: The pressing drive cylinders of the two sets of pressing components operate simultaneously, causing a row of middle strip materials and a row of side strip materials to be ejected from the bottom of their loading fixture, and then mate with the corresponding holes of the clamping components at the designated positions on the side frame to obtain the finished product;

[0020] Step 8: The clamping drive cylinder of the clamping assembly returns to its initial position;

[0021] Step 9: The drive mechanism of the lifting component is activated, and the lifting frame drives the pressing component, clamping component, flipping and pushing component A, flipping and pushing component B, blocking and positioning mechanism and side frame positioning component on it to return to the initial position.

[0022] Step 10: The incoming material conveyor line operates, transporting the finished product to the next workstation;

[0023] Step 11: The corresponding linear modules A and B of the flip-push component A and flip-push component B move, driving the side material push drive group, the middle material push drive group A, and the middle material push drive group B to move. The pusher plate pushes the second row of middle strip materials and the second row of side strip materials in the loading fixture forward by one part position in the loading fixture.

[0024] The beneficial effects of this invention are as follows: An automatic assembly device for strip materials uses a lifting assembly to achieve overall lifting of the pressing assembly, clamping assembly, and flipping / pushing assembly. The pressing assembly vertically conveys the middle and edge strip materials downwards. The clamping assembly maintains the stable position and posture of the strip materials during downward conveying. The flipping / pushing assembly pushes each strip material to the working position of the pressing assembly and flips itself. Furthermore, the directional dimension of the groove A of the sliding clamping seat is designed based on the outer dimension of the C-shaped boss of the middle strip material. When the C-shaped boss passes through groove A, the middle section of the middle strip material will wobble in the channel formed by the sliding clamping seat and the fixed clamping seat, causing a positional deviation. To eliminate this deviation, a sliding mechanism is provided. When the middle strip material is pressed down and contacts the slider, the slider slides towards the compression spring. Under the action of the sliding table mechanism, the position of the middle strip material remains unchanged when passing through the clamping component. Furthermore, since the strip materials are fully loaded in each loading fixture, arranged one next to another, and the position of the pressing component remains fixed, after the front row of strip materials is pressed down, the flipping and pushing component needs to push the position of the rear row of strip materials in the loading fixture forward by one part position, so that the pressing component can continue to press down the strip materials. The side strip materials have different shapes and assembly positions from the middle strip materials; therefore, the side strip materials are handled by the flipping and pushing component A. The material pushing drive groups push independently, with the intermediate strip material pushed by the intermediate strip material pushing drive group A of the flipping pushing component A, and the flipping pushing component B used to push the corresponding intermediate strip material; a push plate buffer group is set between the push plate and the push plate support, and the spring buffer force is used to avoid damage to the strip material; when the strip material and the feeding fixture are being fed, the push plate, push plate support and active push plate support are flipped away from the working position by the flipping cylinder, which facilitates feeding; in summary, the automatic assembly equipment for strip materials of the present invention can effectively improve the feeding efficiency and quality of strip materials.

[0055] An assembly method for the above-mentioned automatic assembly equipment for strip materials includes the following steps:

[0056] Step 1: Flip the flipping and pushing components A5 and B6 away from the loading station;

[0057] Step 2: Place the middle strip material 10, the loading fixture (i.e., the material box for holding the material), and the side strip material 9 into the designated positions at the loading station;

[0058] Step 3: Flip the flip push component A5 and the flip push component B6 back to their initial positions;

[0059] Step 4: When the side frame 11, as incoming material, is conveyed to the designated position, the cylinder 81 of the side frame positioning assembly 8 is activated to fix the side frame 11 on the incoming material conveyor line 12 (when the side frame 11 is conveyed to the designated position through the incoming material conveyor line 12, the cylinder 81 is activated, thereby causing the pressure block 83 to press the side frame 11, thus achieving the positioning of the side frame 11);

[0060] Step 5: The drive mechanism 21 of the lifting assembly 2 is activated, and the lifting frame 25 drives the pressing assembly 3, clamping assembly 4, flipping and pushing assembly A5, flipping and pushing assembly B6, blocking and positioning mechanism 7 and side frame positioning assembly 8 to descend to the designated position together;

[0061] Step 6: The clamping drive cylinder 41 of the clamping assembly 4 is activated, driving the sliding clamping seat 44 to the designated position of the fixed clamping seat 43;

[0062] Step 7: The pressing drive cylinders 32 of the two sets of pressing components 3 operate simultaneously, causing a row of middle strip materials 10 and a row of side strip materials 9 to be removed from the bottom of their loading fixture, and then cooperate with the designated positions on the side frame 11 through the corresponding holes of the clamping component 4 to obtain the finished product;

[0063] Step 8: The clamping drive cylinder 41 of the clamping assembly 4 returns to its initial position;

[0064] Step 9: The drive mechanism 21 of the lifting component 2 is activated, and the lifting frame 25 drives the pressing component 3, clamping component 4, flipping and pushing component A5, flipping and pushing component B6, blocking and positioning mechanism 7 and side frame positioning component 8 on it to return to the initial position.

[0065] Step 10: The incoming material conveyor line 12 operates, conveying the finished product to the next workstation;

[0066] Step 11: The linear modules A541 and B552 corresponding to the flipping push component A5 and flipping push component B6 move, driving the side material push drive group 54, the middle material push drive group A55, and the middle material push drive group B62 to move. The push plate 51 pushes the second row of middle strip material 10 and the second row of side strip material 9 in the loading fixture forward by one part position in the loading fixture.

[0067] It should be noted that the middle strip material 10 has C-shaped protrusions 101 on its upper and lower sides. To allow the middle strip material 10 to pass through the channel formed by the sliding clamping seat 44 and the fixed clamping seat 43, the longitudinal dimension of the rectangular groove A444 of the sliding clamping seat 44 is designed based on the outer dimension of the C-shaped protrusions 101. After the lower C-shaped protrusions 101 pass through the rectangular groove A444, the middle section of the middle strip material 10 will wobble in the channel formed by the sliding clamping seat 44 and the fixed clamping seat 43, resulting in a positional deviation. To eliminate this deviation, a sliding mechanism 46 is provided. When the middle strip material 10 presses down and contacts the slider 443, the slider 443 slides towards the compression spring 447. Under the action of the sliding table mechanism 46, the position of the middle strip material 10 remains unchanged when passing through the clamping component 4. In addition, since the side strip materials 9 and the middle strip materials 10 are fully loaded in each loading fixture and arranged one after another, the position of the pressing component 3 remains fixed. After the front row of side strip materials 9 and middle strip materials 10 are pressed down, the flipping and pushing components A5 and B6 are used to push the position of the rear row of side strip materials 9 and middle strip materials 10 in the loading fixture forward by one part position, so that the pressing component 3 can continue to press down the side strip materials 9 and middle strip materials 10. The side strip materials 9 and middle strip materials 10 have different shapes and assembly positions, so the two side strip materials are handled by the flipping and pushing component A5. The edge strip material push drive group 54 pushes independently, and the middle strip material 10 is pushed by the middle strip material push drive group A55 of the flip push component A5. The flip push component B6 is used to push the corresponding middle strip material 10. A push plate buffer group 561 is set between the push plate 51 and the push plate bracket 53. The buffer force of the spring avoids damage to the side strip material 9 and the middle strip material 10. When the strip material and the feeding fixture are fed, the push plate 51, the push plate bracket 53 or the active push plate bracket 53B are flipped away from the working position by the flip cylinder A548 and the flip cylinder B559 to facilitate feeding. The feeding fixture is placed in the channel formed by the positioning plate 73 and the nylon strip 74. The positioning plate 73 and the nylon strip 74 are used for the lateral positioning of the feeding fixture.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
