Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerator shelf assembly equipment, in particular to an automatic refrigerator shelf assembly device. BACKGROUND

[0002] The shelf inside the refrigerator is usually composed of a glass plate in the middle and decorative strips installed on both sides, and is the core component for layering storage inside the refrigerator. Due to differences in refrigerator models and specifications, existing refrigerator shelves have diversified structural designs, but they still generally rely on manual operation in the assembly process: the operator needs to first position the glass plate, then align the decorative strips with the edges of the glass plate, and fix the decorative strip sleeves on both sides of the glass plate by manual knocking and other methods.

[0003] Because the glass plate is installed inside the refrigerator, one end of the glass plate extends into the inside of the refrigerator, and the other end is close to the refrigerator door. Considering the use performance, the decorative strips on both sides of the glass plate are not the same size, and the decorative strip close to the inside of the refrigerator is usually narrower, while the decorative strip close to the refrigerator door is wider. During the assembly of the decorative strips, the narrow decorative strip is easier to assemble by manual knocking than the wide decorative strip, and the wide decorative strip is prone to deformation and damage during manual assembly, which is not convenient for assembly. SUMMARY

[0004] In order to improve the efficiency of the automatic refrigerator shelf assembly device during use, the present application provides an automatic refrigerator shelf assembly device.

[0005] The present application provides an automatic refrigerator shelf assembly device, which adopts the following technical scheme: An automatic refrigerator shelf assembly device, comprising a case, a support plate for placing a glass plate and a positioning table for placing a decorative strip are installed on the case, a first pressing assembly and a second pressing assembly for pressing are installed on the case, the second pressing assembly comprises a second push plate for pushing the glass plate, a telescopic sleeve is movably installed on the second push plate, an activity plate is installed on the telescopic sleeve, a first pull plate is connected to the activity plate, a second guide rod is installed on the second push plate, a lifting plate is slidably installed on the second guide rod, a second spring is sleeved on the second guide rod, one end of the second spring is connected to the lifting plate, and the other end is connected to the second push plate; a first connecting plate is installed on the lifting plate, a pressing plate for pressing the glass plate is connected to the first connecting plate, a second push rod is hingedly connected to the first pull plate, and one end of the second push rod away from the first pull plate is hingedly connected to the lifting plate.

[0006] By adopting the technical scheme, the second push plate pushes the glass plate to move during assembly, and the glass plate first abuts against the telescopic sleeve; when the glass plate abuts against the decorative strip of the positioning table, the telescopic sleeve is pushed to contract, and then the movable plate and the first pull plate are moved. The first pull plate pulls the lifting plate to slide downward along the second guide rod through the second push rod, and the second spring is compressed. The lifting plate drives the pressing plate to move downward synchronously and press on the surface of the glass plate. The structure realizes linkage of automatic pressing of the push plate moving, avoids tilting and deviation of the glass plate during abutment, does not need manual auxiliary positioning, and greatly improves assembly efficiency and precision.

[0007] In a specific implementable scheme, the pressing plate is hinged with the first connecting plate, a third guide rod is installed on the lifting plate, a moving plate is slidingly installed on the third guide rod, a third spring is sleeved on the third guide rod, one end of the third spring is connected with the moving plate, and the other end is connected with the lifting plate, a first push rod is hinged on the moving plate, and one end of the first push rod away from the moving plate is hinged with the pressing plate; an installation plate is installed on the second push plate, a movable rod is slidingly installed on the installation plate, a limiting ring is arranged on the movable rod, a fourth spring is sleeved on the movable rod, one end of the fourth spring is connected with the limiting ring, and the other end is connected with the installation plate, one end of the movable rod close to the movable plate abuts against the movable plate, and the other end of the movable rod away from the movable plate is installed with a second connecting plate, and the second connecting plate is installed with a third pull plate for driving the moving plate to move.

[0008] By adopting the technical scheme, the movable plate moves synchronously to push the movable rod to slide, the fourth spring is compressed, the movable rod drives the third pull plate to move through the second connecting plate, and then the moving plate slides along the third guide rod and compresses the third spring. During the movement of the moving plate, the pressing plate is driven to rotate around the hinge point of the first connecting plate through the first push rod, so that the pressing plate adapts to the inclined structure of the glass plate surface on which the decorative strip is assembled, and realizes the fitting pressing. The design can automatically adjust the angle of the pressing plate according to the shape of the decorative strip, avoid damage of components caused by rigid pressing, and improve the pressing stability.

[0009] In a specific implementable scheme, a sliding groove is formed in the movable plate, a sliding block for driving the movable rod to move is slidingly installed in the sliding groove, a sliding rod is installed on the installation plate, the sliding rod is inclined, one end of the sliding rod away from the installation plate is lower than the end connected with the installation plate, the sliding rod passes through the sliding block and is slidingly connected with the sliding block, and a through hole is formed in the movable plate for the movement of the sliding rod.

[0010] By adopting the technical scheme, when the movable plate moves, the sliding block slides along the inclined guide of the sliding rod and moves towards the direction close to the movable rod. After the sliding block abuts against the movable rod, the movable rod is further pushed to move, thereby realizing double driving of the movable rod, i.e. direct pushing and auxiliary pushing by the sliding block, accelerating the response speed of the linkage of the third pull plate and the movable plate, and enabling the pressing plate to rotate quickly before pressing the decorative strip. The through hole provides a moving space for the sliding rod, avoids interference between the movable plate and the sliding rod when the movable plate moves, and ensures smooth operation of the mechanism.

[0011] In a specific implementable scheme, the sliding groove is a dovetail groove, and the cross section of the sliding block is also dovetail-shaped.

[0012] By adopting the technical scheme, the matching structure of the dovetail groove and the dovetail-shaped sliding block can limit the sliding block from deviating in the vertical direction and only allow it to slide in the length direction of the sliding groove, thereby improving the stability of the sliding block during sliding, avoiding driving failure of the movable rod due to deviation of the sliding block, and ensuring reliable operation of the pressing mechanism.

[0013] In a specific implementable scheme, the end of the movable rod abutting against the movable plate is in a ball head shape, and the end close to the movable rod of the sliding block is provided with a chamfered surface.

[0014] By adopting the technical scheme, the ball head shape design reduces the contact friction between the movable rod and the movable plate, and makes the movable rod slide more smoothly. The chamfered surface changes the contact between the sliding block and the movable rod from surface contact to point-line contact, reduces the frictional resistance, and efficiently converts the horizontal moving force of the sliding block into the axial pushing force of the movable rod, thereby improving the power transmission efficiency.

[0015] In a specific implementable scheme, the second push plate is provided with a first guide rod, the first guide rod is provided with the telescopic sleeve in a sliding manner, the first guide rod is provided with a first spring in a sleeving manner, one end of the first spring is connected with the telescopic sleeve, and the other end of the first spring is connected with the second push plate.

[0016] By adopting the technical scheme, the first guide rod provides a directional sliding track for the telescopic sleeve, thereby avoiding deviation of the telescopic sleeve. When the telescopic sleeve is contracted by the reaction force of the glass plate, the first spring can store elastic potential energy. When the glass plate is separated from the abutment after assembly, the first spring releases the potential energy to push the telescopic sleeve to reset, thereby preparing for the next assembly cycle and realizing the automatic resetting function of the telescopic sleeve.

[0017] In a specific implementable scheme, the case is provided with a transportation mechanism for transporting the glass plate, the transportation mechanism comprises a pneumatic cylinder, the pneumatic cylinder is installed on the case, an output shaft of the pneumatic cylinder is provided with a lifting frame, the lifting frame is provided with a transportation belt, and the lifting frame is provided with a motor for controlling the operation of the transportation belt.

[0018] Through the above technical scheme, after assembly is completed, the cylinder drives the lifting frame to rise, the conveying belt supports the glass plate and lifts it off the support plate; the motor drives the conveying belt to run, and the assembled shelf is automatically transported to the next process. The mechanism realizes automatic discharging and transfer of the shelf, replaces manual handling, and further improves the production automation degree and overall assembly efficiency.

[0019] In a specific implementable scheme, the first pressing assembly comprises a first electric cylinder, and a first push plate is mounted on an output shaft of the first electric cylinder, and a push groove is formed in the first push plate.

[0020] Through the above technical scheme, the first electric cylinder provides stable pushing force to drive the first push plate to push the decorative strip on the positioning table; the push groove can be matched with the shape of the decorative strip, so that the pushing force is accurately applied to the stress part of the decorative strip, avoiding the displacement or tilting of the decorative strip during pushing, and improving the positioning accuracy and pressing reliability of the decorative strip.

[0021] In a specific implementable scheme, a positioning groove for positioning the decorative strip is formed in the positioning table.

[0022] Through the above technical scheme, the vertical ear structure of the decorative strip can be embedded in the positioning groove, realizing rapid positioning and limiting of the decorative strip in the horizontal direction, avoiding displacement of the decorative strip when the first pressing assembly pushes, providing pre-protection for accurate butt joint of the decorative strip and the glass plate, and reducing assembly error.

[0023] In summary, the present application has at least one of the following beneficial technical effects: 1. Realize full-process automation linkage: through the cooperation of the first pressing assembly, the second pressing assembly and the conveying mechanism, all processes such as positioning of the decorative strip, pushing of the glass plate, pressing and transfer of the finished product are completed by replacing manual operation, solving the problem of low efficiency of manual assembly, and meeting the demand of large-scale production.

[0024] 2. Improve assembly positioning accuracy and product qualification rate: the positioning groove of the positioning table realizes accurate limiting of the decorative strip, and the linkage pressing mechanism of the second pressing assembly can automatically adapt to the shape of the decorative strip and apply stable pressure, avoiding assembly error and component damage caused by manual positioning deviation and uncontrollable knocking force, and significantly improving product qualification rate.

[0025] 3. Stable operation and strong adaptability: through the cooperation of multiple springs and guide structures, smooth sliding and automatic reset of each moving part are realized; the angle of the pressing plate can be automatically adjusted according to the slope of the decorative strip, adapting to the assembly requirements of shelves of different specifications, and improving the universality of the device.
