[0002] Refrigerator interior shelves are an important component of the refrigerator's interior, serving to divide the internal space and store food. With societal progress, refrigerator layouts are constantly evolving, and irregularly shaped glass shelves are becoming increasingly common. Typically, glass shelves consist of three parts: an irregularly shaped glass panel, a front decorative strip, and a rear decorative strip, with the front and rear strips respectively snapping onto the front and rear ends of the glass panel. However, current standard tooling cannot automate the assembly of these decorative strips onto the irregularly shaped glass panel; therefore, assembling irregularly shaped refrigerator shelves currently relies entirely on manual labor, which is time-consuming and labor-intensive. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a simple and rationally designed assembly and pressing fixture for irregularly shaped shelves. This fixture automates the process of attaching the front and rear decorative strips to the irregularly shaped glass plate, thereby saving manpower and improving work efficiency.

[0024] The bottom of the second recess is provided with a second through hole, which passes through the second rubber plate and the third rigid plate;

[0025] A fourth rigid plate is provided on the side of the third rigid plate opposite to the front decorative strip. The fourth rigid plate is provided with a second groove, which connects the second through hole.

[0026] A second micro air pump is provided on the side of the fourth rigid plate opposite to the front decorative strip, and the second micro air pump is connected to the second groove.

[0027] Furthermore, the third adsorption block includes a fifth rigid plate, and a third rubber plate is provided on the lower side of the fifth rigid plate, and the third rubber plate is provided with a plurality of third recesses;

[0031] Furthermore, the second rubber block has a first recess on one side of the front trim strip, and the edge of the first recess matches the shape of the front trim strip away from the opening side.

[0032] The slope of the first recessed edge is 10-30°.

[0033] Furthermore, the third rubber block has a second recess on one side that is in contact with the rear trim strip, and the edge of the second recess matches the shape of the rear trim strip away from the opening side;

[0034] The slope of the second recessed edge is 10-30°.

[0035] Furthermore, a first resistance rubber block is provided above the front trim strip, and the first resistance rubber block is located at the front end of the front trim strip array;

[0036] When the second adsorption block rotates to the front end of the front decorative strip queue, only the upper end of the frontmost front decorative strip is disengaged from the first resistance rubber block;

[0037] The first resistance rubber block presses against the upper ends of two or three of the front trim strips.

[0038] Furthermore, a second resistance rubber block is provided above the rear trim strip, and the second resistance rubber block is located at the front end of the rear trim strip array;

[0039] When the third adsorption block rotates to the front end of the rear decorative strip queue, only the upper end of the frontmost rear decorative strip disengages from the second resistance rubber block;

[0040] The second resistance rubber block presses against the upper ends of two or three of the rear trim strips.

[0041] Furthermore, the first conveyor belt is provided with baffles, which are arranged perpendicular to the longitudinal direction of the first conveyor belt. Both ends of the baffles are provided with folded edges, which form a trumpet-shaped opening facing the moving irregular glass plate. The length of the long straight portion of the baffle between the folded edges is equal to the width of the irregular glass plate.

[0042] Both ends of the long straight section of the baffle are equipped with a first pressure sensing switch.

[0043] The second adsorption block is equipped with a second pressure sensing switch.

[0044] The third adsorption block is equipped with a third pressure sensing switch.

[0045] The first pressure sensor switch, the second pressure sensor switch, and the third pressure sensor switch are connected to the control cabinet.

[0046] The second and third conveyor belts are provided with longitudinal protrusions to position the front and rear decorative strips left and right.

[0047] During operation, the first conveyor belt runs at a constant speed. When one end of the irregularly shaped glass plate is located between the two folds of the baffle, the first pressure sensor switches at both ends of the baffle detect the pressure from the irregularly shaped glass plate, and the pressure signal is transmitted to the control cabinet. The air-cushion cylinder push rod moves downward, causing the first adsorption block to contact the irregularly shaped glass plate. Then, the first micro air pump starts, and the irregularly shaped glass plate is adsorbed onto the first adsorption block.

[0048] As the air-lift cylinder moves downwards, the second conveyor belt starts, causing the front trim strip to adhere to the second adsorption block. Then, the second micro-pump starts, and the front trim strip is adsorbed onto the second adsorption block.

[0049] As the air-lift cylinder moves downwards, the third conveyor belt starts, causing the frontmost rear trim strip to adhere to the third adsorption block. Then, the third micro-pump starts, and the rear trim strip is adsorbed onto the third adsorption block.

[0050] When the cylinder rod retracts upward, the second and third adsorption blocks rotate upward.

[0051] When the cylinder push rod retracts to the predetermined position, the second and third adsorption blocks rotate to a horizontal position. At this point, the openings of the front and rear trim strips are aligned with the front and rear sides of the irregularly shaped glass panel.

[0052] Then, the first and second telescopic rods begin to extend, pressing and snapping the front and rear trim strips onto the irregularly shaped glass panel.

[0053] After the extrusion process is completed, the second and third adsorption blocks stop pumping air and detach from the front and rear trim strips, respectively. The first and second telescopic rods retract.

[0054] The movable frame moves behind the baffle bar, and then the air-cushion cylinder rod extends, bringing the irregularly shaped glass plate closer to the first conveyor belt. The first adsorption block stops pumping air, and the irregularly shaped glass plate detaches from the first adsorption block and re-enters the first conveyor belt.

[0055] Then, the movable frame moves forward of the baffle and re-enters the workstation for adsorbing irregularly shaped glass plates.

[0056] At the same time, the second and third adsorption blocks rotate downwards and enter the work station for adsorbing the front and rear decorative strips.

[0057] The beneficial effects of this solution can be seen from the description of the above solution: the structure is simple and the design is reasonable, which automates the process of attaching the front and rear decorative strips to the irregular glass plate, thereby saving manpower and improving work efficiency.

[0058] On the conveyor belt, the plastic material used for decorative strips on refrigerator glass panels is generally difficult to insert under the glass, especially when the strips are irregularly shaped. Excessive force can easily damage the strips; even if they don't break, excessive force can cause the glass panel to shift, resulting in inaccurate positioning. Using a first suction block to pull the irregularly shaped glass panel away from the first conveyor belt facilitates the insertion of the front and rear decorative strips under the panel. Furthermore, when the strips are pushed up, the irregularly shaped glass panel does not shift, ensuring accurate positioning.

[0059] When the glass plate moves on the conveyor belt, its position is uncertain. Therefore, this application sets a baffle to position the irregularly shaped glass plate as needed, and then uses a first adsorption block to adsorb the irregularly shaped glass plate at the accurate position. This not only facilitates the subsequent clamping process, but also, since irregularly shaped glass plates often have vents, accurate positioning makes it easier for the adsorption block's adsorption pits to avoid the vents in the glass plate.

[0060] Because of the presence of the baffles, the irregularly shaped glass plates that have been processed need to be placed onto the first conveyor belt at the rear, which requires a different method of movement. Therefore, guide rails and movable frames are installed.

[0061] The first, second, and third adsorption blocks employ an active air extraction structure, rather than relying on squeezing rubber cups to generate adsorption force, because they need to detach smoothly at the appropriate time. This detachment is achieved by connecting to the atmosphere via an electromagnetic vent valve.

[0062] The second rubber plate has a first recess, and the third rubber plate has a second recess. Firstly, this is used to align the positions of the front and rear trim strips; as long as the relevant positions of the front and rear trim strips align with the edges of the recesses, they are in the designed positions. Secondly, during the snap-fit ​​process, the front and rear trim strips need to be pushed forcefully; the edges of the recesses provide support for this pushing action. Thirdly, because rubber is used, directly pushing with the recesses does not easily cause damage from hard compression. In other words, the simple recess design is very beneficial for solving technical problems.

[0063] To save space, the front and rear decorative strips are placed on the conveyor belt with their openings facing downwards and close together. However, since the decorative strips are very light and the width of this placement is much smaller than its height, the decorative strips at the front of the queue are prone to tipping over. Therefore, a first resistance rubber block and a second resistance rubber block are installed. This not only prevents the decorative strips from tipping over but also makes the queue of decorative strips compact and saves space.

[0064] These small technical improvements make it possible to automatically snap irregularly shaped decorative strips and glass panels onto an assembly line while ensuring reliability and quality. Attached Figure Description
