[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, a refrigerator drawer body and panel automatic assembly device includes a body positioning assembly 1, a panel positioning assembly 2, a panel pushing and positioning assembly 3, a pressing assembly 4 and a panel flipping assembly 5 arranged on a frame assembly 6. The panel positioning assembly 2, the panel pushing and positioning assembly 3 and the pressing assembly 4 are integrally connected to the body positioning assembly 1 through a seat bearing 51;

[0033] The main body positioning assembly 1 includes a rotary downward pressing cylinder, which is used to press down and clamp the positioning main body;

[0034] The panel positioning assembly 2 includes a panel transverse positioning cylinder, which is used to position the panel transversely;

[0035] The panel pushing and positioning assembly 3 includes a pushing and positioning cylinder 31, which is used to longitudinally position the panel and push the panel in the pressing area to fit the joint portion of the main body;

[0036] The panel flip assembly 5 includes a flip cylinder 53, which is used to drive the panel to flip to the pressing area;

[0037] The pressing assembly 4 is used to press the panel and the main body to complete the assembly.

[0038] like Figure 2 As shown, the main body positioning assembly 1 includes a length direction positioning block 14 in the middle, and a reference side width direction positioning block 12 and a width direction positioning block 15 on both sides; the length direction positioning block 14 is arranged on the length direction positioning block template 13, and the main body positioning assembly 1 is provided with a reference side clamping cylinder 11 for clamping the main body at the position corresponding to the reference side width direction positioning block 12; the main body positioning assembly 1 is provided with a narrow main body clamping cylinder 18 for clamping the main body at the position corresponding to the width direction positioning block 15.

[0039] The main body positioning assembly 1 also includes a width-direction positioning block 2 16. The distance between the width-direction positioning block 2 16 and the reference side width-direction positioning block 12 is greater than the distance between the width-direction positioning block 15 and the reference side width-direction positioning block 12. The main body positioning assembly 1 is provided with a wide main body clamping cylinder 17 at the position corresponding to the width-direction positioning block 2 16, and the narrow main body clamping cylinder 18 is detachable.

[0040] The main product that needs to be assembled has two sizes in the width direction and five sizes in the length direction, and the equipment needs to be compatible.

[0041] According to the product model, adjust the position of the length direction positioning block 14 on the length direction positioning block template 13, and insert the two pins on the positioning block into the pin holes corresponding to the product model identification in the template.

[0042] When producing a wide main body, the reference side pressing cylinder 11 and the wide main body pressing cylinder 17 are actuated to position and press the main body. When producing a narrow main body, the reference side pressing cylinder 11 and the narrow main body pressing cylinder 18 are actuated to position and press the main body.

[0043] like Figure 3 As shown, the panel positioning assembly 2 includes a central polytetrafluoroethylene pad 21, and a reference side plate 22 and a movable side plate 25 on both sides. A lateral positioning cylinder 23 and a linear guide pair 26 are arranged between the reference side plate 22 and the movable side plate 25. The movable side plate 25 can slide laterally along the linear guide pair 26 under the drive of the lateral positioning cylinder 23.

[0044] The panel positioning assembly 2 also includes a second transverse positioning cylinder 24 , the stroke of which is different from that of the first transverse positioning cylinder 23 , and the second transverse positioning cylinder 24 is used to drive the movable side plate 25 to slide transversely along the linear guide pair 26 .

[0045] The panel products that need to be assembled have two sizes in the width direction and the same size in the length direction, and the equipment must be compatible.

[0046] When producing wide panels, the initial state is that horizontal positioning cylinder 1 23 extends, while horizontal positioning cylinder 2 24 extends and retracts. When producing narrow panels, the initial state is that horizontal positioning cylinder 1 23 extends and retracts, while horizontal positioning cylinder 2 24 extends. When the equipment is automatically operating, only horizontal positioning cylinder 2 24 is in motion, horizontally positioning the panel. During positioning, the panel is not clamped tightly, leaving a gap of about 0.5-1mm.

[0047] like Figure 4 As shown, the panel positioning assembly 3 includes at least two symmetrically arranged positioning cylinders 31. The positioning cylinders 31 are located outside the panel workpiece 34, that is, on the side away from the panel rotation axis, and the pushing direction of the positioning cylinders 31 is toward the panel rotation axis. The positioning cylinders 31 are fixed to the large rotation plate 52 via a positioning cylinder mounting plate 33. The panel workpiece 34 is placed on the polytetrafluoroethylene backing plate 21 of the panel positioning assembly 2. The pushing portion of the positioning cylinders 31 is provided with a polyurethane pressure block 32.

[0048] The loading robot sucks the panel and places it into the panel positioning area of ​​the assembly machine, pushes the positioning components, and positions the panel longitudinally before flipping it over. After the panel is flipped into place, it moves again to fit the joint between the panel and the main body into place, facilitating the final pressing action.

[0049] like Figure 5 As shown, the pressing assembly 4 includes an auxiliary pressing cylinder 41, a fixed pressing cylinder 45, and a movable pressing cylinder 44. The fixed pressing cylinder 45 is mounted on the flip plate 52 of the panel flip assembly 5, and the movable pressing cylinder 44 is mounted on the movable side plate 25 of the panel positioning assembly 2. The fixed pressing cylinder 45 and the movable pressing cylinder 44 both press horizontally. The auxiliary pressing cylinder 41 is mounted on the fixed pressing cylinder 45 and presses vertically. A polyurethane push block 42 is provided on the telescopic portion of each of the four cylinders. The fixed pressing cylinder 45 and the movable pressing cylinder 44 are both fixed by a pressing cylinder mounting plate 43.

[0050] Two fixed pressing cylinders 45 are installed on the flip plate 52 of the panel flip assembly 5, and a movable pressing cylinder 44 is installed on the movable plate of the panel positioning assembly 2. After the previous actions are completed in sequence, the four pressing cylinders act simultaneously, and finally the panel and the main body are assembled.

[0051] like Figure 6 As shown, the panel flip assembly 5 includes a seat bearing 51, a flip plate 52, a flip cylinder 53 and a cylinder connecting block 54;

[0052] One end of the flip cylinder 53 is connected to the frame assembly 6, and the other end is connected to the flip plate 52 through the cylinder connecting block 54. The flip plate 52 is rotatably connected to the main positioning assembly 1 through the seat bearing 51, and the panel positioning assembly 2, the panel push positioning assembly 3, and the pressing assembly 4 are all installed on the flip plate 52.

[0053] The loading robot sucks the panel and places it into the panel positioning area of ​​the assembly machine. After the horizontal and vertical positioning cylinders of the panel are activated, the flipping assembly drives the panel to flip, facilitating subsequent actions.

[0054] like Figure 7 As shown, the rack assembly 6 includes an assembly equipment plate 62, a welded square tube frame 63, and adjustable foot cups 64. The assembly equipment plate 62 is installed on the welded square tube frame 63, and the adjustable foot cups 64 are set at the four corners of the bottom of the welded square tube frame 63.

[0055] The frame assembly 6 also includes a main body positioning assembly mounting plate 61, which is mounted on a large assembly plate 62. The main body positioning assembly 1 is mounted on the main body positioning assembly mounting plate 61. The frame assembly 6 serves as the mounting carrier for the entire device, ensuring that the various components are reliably connected and coordinated, and that the assembly of the panel and the main body is completed smoothly.

[0056] Working process: The loading robot sucks the panel from the tooling car and places it into the panel positioning area of ​​the assembly machine; the panel horizontal positioning cylinder extends to position the panel horizontally (without clamping the panel, leaving a 0.5-1mm gap); the push-to-position positioning cylinder 31 extends to position the panel longitudinally, and the cylinder retracts after positioning.

[0057] The loading robot sucks up the main body positioned at the end of the belt line and places it on the main body positioning block of the assembly machine; the corresponding main body's rotating downward pressing cylinder presses down and clamps the positioning main body; the flipping cylinder 53 drives the panel to flip upward to the predetermined position (the panel should not touch the upper part of the main body at this time); the pushing positioning cylinder 31 is extended to make the joint between the panel and the main body fit together, and the cylinder retracts after it is in place; the pressing cylinder is extended to complete the assembly of the panel and the main body, and then the cylinder retracts.

[0058] The lateral positioning cylinder retracts, the turning cylinder 53 retracts, the rotary pressing cylinder retracts (returns to the original state), and the loading robot stacks the assembled drawers onto the tooling vehicle, and the cycle continues.

[0059] The present invention cooperates with loading and unloading robots to realize automatic assembly of the main body and the panel, replacing the traditional manual operation method. While greatly improving production efficiency, it also saves labor costs and improves product and management quality.

[0060] In addition, the main body and the cover plate of the present invention have an R-arc joint on one side that needs to be combined, and a convex point and a small hole on the other side that need to be combined, which requires a complex combination of actions to achieve and cannot be directly assembled through simple linear motion. Therefore, a flip assembly is used.

[0061] When the main body of the present invention is made of PP material, after coming out of the injection molding machine, due to the influence of temperature, the size and shape of each main body will be different, some are relatively regular, and some will be shaped like an eight. The V-shaped positioning blocks in the main body positioning assembly 1 of the equipment guide the correction (i.e., the length direction positioning block 14, the reference side width direction positioning block 12, the width direction positioning block 15, and the width direction positioning block 2 16), so that the main body and the panel can be assembled smoothly.

[0062] The present invention can also be compatible with the assembly of products of various specifications and sizes. Through the cooperation of the equipment and the robot, the material is automatically loaded and unloaded, and the assembly work is automatically completed without manual operation throughout the process.

[0063] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
