Description

Technical Field

[0001] This invention relates to the field of refrigerator glass shelf trim installation and cotton application technology, specifically a fully automatic refrigerator glass shelf trim installation and cotton application machine. Background Technology

[0002] The refrigerator glass layer is the core component inside the refrigerator that holds the stored items. Plastic trim strips need to be installed around the glass layer to provide edge protection and enhance the appearance. At the same time, cushioning foam is pasted on the back of the glass to prevent the glass from making abnormal noises or scratches due to hard contact with the refrigerator's sheet metal body.

[0003] Traditional glass panel trim assembly and foam application processes are mostly done manually in segments, resulting in fragmented operations that require multiple machines for segmented processing. This necessitates manual placement of the panels, one machine pressing the trim, and another manually applying the cushioning foam. The workpieces require multiple transfers and loading / unloading operations, which easily scratch the glass surface. Manual transfer is time-consuming, and the entire production line requires a large workforce, leading to high labor costs. Workers manually squeezing the trim with hand-held tools are prone to trim misalignment, partial detachment, and uneven lengths at both ends. In mass production, product consistency is poor, resulting in a high defect rate. Furthermore, the foam rolls require manual cutting and... Manually aligning and pasting the foam on the back of the glass is prone to problems such as foam misalignment, wrinkles, and air bubbles, as well as misalignment of foam edges. Thin cushioning foam is also easily wrinkled when handled manually. Pasting foam on each piece of glass is time-consuming and cannot keep up with the production speed of the front-end glass cutting and edge grinding production line, creating a processing bottleneck. Moreover, the processed glass layers need to be manually handled and stacked one by one. During the stacking process, the glass is prone to collisions and edge breakage. Manual stacking is labor-intensive, and long-term repetitive work can lead to fatigue, as well as safety hazards such as scratches and breakage. The degree of automation is also low. To address these issues, we provide a fully automatic refrigerator glass shelf trim installation and foam pasting machine. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic refrigerator glass shelf trim installation and cotton-applying machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic refrigerator glass shelf trim installation and cotton-applying integrated machine, comprising a machine base, a shelf feeding conveyor frame installed on the left side of the machine base, a feeding conveyor mounted on the shelf feeding conveyor frame, a trim feeding component mounted on the front side of the top of the machine base, an automatic extrusion trim installation component mounted on the top of the machine base and located behind the trim feeding component, an automatic cotton-applying component mounted on the top of the machine base and located behind the automatic extrusion trim installation component, and an automatic stacking and unloading component mounted on the back of the machine base.

[0006] Optionally, the trim feeding assembly includes a placement platform and a feeding rack. The placement platform is installed on the top of the machine, and a conveyor is installed on the machine at a position corresponding to the placement platform. The feeding rack is installed on the top of the machine at a position corresponding to the placement platform.

[0007] Optionally, a feeding transverse frame is connected to the feeding rack via a motor and a lead screw. A feeding cylinder is installed on the feeding transverse frame. A moving plate is installed at the output end of the feeding cylinder. Several feeding suction cups are installed at the bottom of the moving plate.

[0008] Optionally, the automatic extrusion trim installation assembly includes a top pressing frame, which is installed on the top of the machine base, and the automatic extrusion trim installation structure is mounted on the top pressing frame.

[0009] Optionally, the automatic cotton applicator includes a feeding roller and a connecting frame. The feeding roller has four rollers, each rotatably connected to the machine base. A material strip is wound around the feeding roller. The connecting frame is mounted on the top of the machine base. A transverse movement structure is connected to the connecting frame via a motor drive. A drive cylinder is mounted on the transverse movement structure. An adjustment plate is mounted on the output end of the drive cylinder. Several suction cups are mounted on the bottom of the adjustment plate. An automatic cotton applicator is provided on the transverse movement structure.

[0010] Optionally, the automatic stacking and unloading assembly includes an unloading frame and an unloading conveyor frame. The unloading frame is installed on the back of the machine base. A transverse moving structure is connected to the unloading frame via a motor drive. An unloading cylinder is installed on the transverse moving structure. A movable plate is installed at the output end of the bottom of the unloading cylinder. Several unloading suction cups are installed at the bottom of the movable plate. The unloading conveyor frame is installed on the back of the unloading frame. An unloading conveyor is installed on the unloading conveyor frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The machine of this invention is a unified support base. The shelf feeding and conveying frame, the trim feeding component, the automatic extrusion trim installation component, the automatic cotton application component, and the automatic stacking and unloading component are sequentially connected and integrated into one unit along the production line. This eliminates the traditional production mode where trim pressing, cotton application, and loading and unloading are done on multiple independent machines. There is no need for manual transfer of glass shelves between multiple toolings, which completely eliminates the problems of glass surface scratches and edge chipping during the transfer process. The entire process is fully automated and continuous, requiring only a small number of operators. This significantly reduces the number of workers in the workshop, significantly reduces labor production costs, and at the same time reduces the equipment footprint and improves the degree of automation.

[0013] 2. The shelf feeding conveyor of this invention is equipped with a feeding conveyor that automatically transports the shelf to be processed. The feeding transverse frame is driven by a screw to move laterally. With the help of a feeding cylinder and multiple sets of feeding suction cups, the shelf is vacuum-adsorbed and moved to the position of the placement table. At the same time, the decorative strip is picked up from the placement table and precisely aligned with the edge of the glass shelf. This replaces manual hand-held placement of the decorative strip, resulting in higher positioning accuracy. The automatic extrusion decorative strip installation component is equipped with an overall pressure frame and an automatic extrusion decorative strip installation structure. It can apply extrusion force synchronously and evenly along the entire glass section. Compared with manual single-point hand-held extrusion fixtures, the decorative strips have no deviation, no local detachment, and uniform length at both ends. The appearance and size consistency of batch processed products are greatly improved, effectively reducing the probability of defective products such as decorative strip detachment and excessive assembly gaps.

[0014] 3. The automatic foam applicator of this invention is equipped with multiple sets of feeding rollers that can simultaneously load multi-specification buffer foam strips. The motor-driven lateral movement structure drives the driving cylinder and suction cups to accurately adsorb the foam. The automatic foam applicator is uniformly and evenly applied to the back of the glass throughout the entire process, completely avoiding the wrinkles, bubbles, misalignment of edges and corners, and thin foam adhesion problems that occur with manual foam applicator. The flatness of the foam applicator is stable, eliminating the hidden dangers of glass noise and sheet metal scratches during refrigerator use. By setting up an automatic stacking and feeding component, the lateral movement structure, together with the feeding cylinder and feeding suction cup, vacuum grabs the finished glass and automatically and neatly stacks it to the feeding conveyor. There is no need for manual handling and stacking of each piece, which greatly reduces the labor intensity of workers carrying repetitive materials and eliminates the safety risks of stacking collisions and breakage. All motors, cylinders, and suction cups of the whole machine can be linked in a unified sequence, enabling continuous automated production 24 hours a day. The processing speed matches the production capacity of the front-end glass cutting and edge grinding line, completely solving the production bottleneck of the foam applicator process and significantly improving the overall utilization rate of the equipment.

[0027] When in use, the operator first completes the machine's self-test, powers on the PLC control system, installs the buffer foam rolls onto the four feeding rollers 51 in sequence, places the refrigerator glass shelves to be processed continuously on the feeding end of the feeding conveyor 21 of the shelf feeding conveyor frame 2, presets the processing parameters such as the transverse speed, downward stroke, and holding time on the control panel, and the equipment enters the standby state for processing.

[0028] When in use, the operator first completes the machine's self-test, powers on the PLC control system, installs the cushioning foam rolls onto the four feeding rollers 51 in sequence, neatly stacks the batch of plastic edging trim strips on the surface of the placement table 31, and continuously places the refrigerator glass shelves to be processed onto the feeding end of the feeding conveyor 21 of the shelf feeding conveyor 2. The operator presets the processing parameters such as the transverse speed, downward stroke, and holding time on the control panel, and the equipment enters the standby state for processing.

[0029] The feeding conveyor 21 is started, which smoothly transports a single refrigerator glass shelf to below the feeding suction cup 37. The trim feeding assembly 3 is started, and the servo motor drives the feeding transverse frame 34 to slide laterally to directly above the refrigerator glass shelf. The feeding cylinder 35 drives the moving plate 36 to extend downward. Multiple sets of feeding suction cups 37 are connected to the vacuum generator to generate negative pressure and adsorb the refrigerator glass shelf. Then the feeding cylinder 35 is raised, and the feeding transverse frame 34 moves laterally in the opposite direction to accurately transfer the refrigerator glass shelf to the position of the placement table 31.

The conveyor 33 is started to transport it to the position of the automatic extrusion trim installation assembly 4.

[0030] When the automatic extrusion trim installation component 4 is activated, the automatic extrusion trim installation structure 42 on the pressure frame 41 is fed downward as a whole. Multiple sets of synchronous pressure rollers uniformly extrude the trim along the entire glass section, so that the plastic trim is tightly fastened to the edges of the glass. After extrusion is completed, the extrusion structure is automatically raised to eliminate the problems of trim offset, disengagement and uneven length caused by manual single-point extrusion.

[0031] When the automatic foam applicator 5 is activated, the feeding roller 51 releases the buffer foam strip at a uniform speed. The lateral movement structure 500 drives the drive cylinder 53 to move laterally above the foam. The drive cylinder 53 presses down, and the suction cup 55 grabs the shelf with negative pressure. The lateral movement structure 500 moves the shelf to the position of the automatic foam applicator 56 and then lowers it. At the same time, the foam moves to the back of the glass through the guide. The automatic foam applicator 56, together with the rolling module, presses down and rolls at a uniform speed to apply the foam flat to the back of the glass without bubbles or wrinkles.

[0032] When the automatic stacking and feeding assembly 6 is activated, the lateral moving structure 63 moves laterally to above the processed glass. The feeding cylinder 64 drives the movable plate and feeding suction cup to extend downwards, and the finished glass is adsorbed by negative pressure.
