Technical Field
[0001] This utility model belongs to the field of refrigerator manufacturing technology, and in particular relates to an assembly device for refrigerator manufacturing. Background Technology
[0002] Refrigerators are common household appliances. The low temperature environment of a refrigerator effectively inhibits the growth of microorganisms, thus helping to keep food fresh, extend its shelf life, and prevent spoilage. During the refrigerator manufacturing process, components such as the refrigerator door need to be installed onto the refrigerator body on the assembly line.
[0003] Through research and combining practical experience in refrigerator manufacturing and assembly, it was found that the installation of refrigerator doors on assembly lines is currently mainly done manually. However, with product upgrades, modern refrigerator doors often feature a single piece of tempered glass for aesthetic purposes. Combined with the weight of the door panel itself, manual installation is not only physically demanding but also typically requires two people, resulting in wasted labor costs, slow assembly speed, and low efficiency. Therefore, there is an urgent need to improve upon existing shortcomings and provide a more efficient assembly device for refrigerator production. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a refrigerator production assembly device that is reasonably designed, simple in structure, easy and labor-saving to install, convenient for single-person operation, and has a faster assembly speed and higher efficiency, thereby solving the problems existing in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An assembly device for refrigerator production includes a base and a control box. A vertical plate is fixedly installed at the upper middle part of the base, and a height adjustment component is provided directly behind the vertical plate. The control box is fixedly installed at the upper rear of the base. An installation box is provided in front of the vertical plate. A clamping component is installed inside the installation box. A soft pad is glued to the front end of the installation box. A fixing box is embedded in the middle of the installation box. Guide grooves are provided inside both the upper and lower ends of the fixing box. A T-shaped rod is slidably installed on the inner side of the fixing box. The front end of the middle part of the T-shaped rod is glued to the soft pad.
[0007] In a preferred embodiment, the vertical plate has a limiting groove inside, and the control box has symmetrical diagonal braces on its left and right sides. The two ends of the diagonal braces are welded and fixed to the base and the vertical plate, respectively. The base, the vertical plate and the diagonal braces form a triangular structure.
[0008] In a preferred embodiment, the height adjustment assembly includes a servo motor, a lead screw, and a movable block. The servo motor is fixedly installed on the outer wall of the top rear end of the vertical plate, and the output end of the servo motor is fixedly connected to the lead screw. The movable block is threaded onto the outer side of the lead screw.
[0009] In a preferred embodiment, the movable block is slidably positioned in the limiting groove, and the mounting box is fixedly mounted on the front end of the movable block.
[0010] In a preferred embodiment, the clamping assembly includes a first crossbar, a second crossbar, clamping plates, rubber pads, and multi-section electric push rods. The first and second crossbars are symmetrically arranged about the central axis of the mounting box. Two second crossbars are located between two first crossbars. Clamping plates are fixedly connected to the ends of the first and second crossbars that are far apart from each other. Rubber pads are embedded on the front ends of the two clamping plates that are close to each other. The two multi-section electric push rods are respectively fixedly installed on the left and right outer walls of the mounting box. The telescopic ends of the two multi-section electric push rods are respectively fixedly connected to the two clamping plates.
[0011] In a preferred embodiment, the first crossbar and the second crossbar have the same shape and size, and both of them have through grooves inside their adjacent ends. The through grooves include inclined sections and straight sections, and the straight sections are connected to the inclined sections.
[0012] In a preferred embodiment, the upper and lower ends of the T-shaped rod pass through the guide groove and are guided to slide inside the groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In the solution of this utility model:
[0015] Place the refrigerator door in front of the base, ensuring the outer surface of the door is tightly against the soft pad. Then, activate the two multi-section electric push rods to bring the two clamping plates closer together, clamping the refrigerator door. As the two clamping plates move the first and second crossbars respectively, the inclined sections of their internal through grooves can be used to push the T-shaped rods backward along the guide grooves. This pulls the middle of the soft pad towards the fixing box, creating a sealed cavity with a lower-than-normal air pressure between the soft pad and the refrigerator door surface. This facilitates the adsorption and positioning of the refrigerator door, achieving a dual positioning effect and ensuring the stability of the refrigerator door during subsequent lifting and installation.
[0016] This device is designed to be portable, making it easy to push the device and refrigerator door to one side of the production line. Then, by starting the servo motor, the rotation of the long screw can control the movable block to drive the mounting box and the refrigerator door it holds to move vertically and vertically in sync. This makes it easy to raise the refrigerator door to the appropriate installation position, and then a single person can install it. This not only saves manpower but also speeds up the installation process and effectively improves the assembly efficiency of the refrigerator. Attached Figure Description

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:
[0027] like Figure 1-6As shown, the assembly device for refrigerator production of this utility model includes a base 1 and a control box 5. A vertical plate 2 is fixedly provided at the upper middle part of the base 1. A height adjustment component 4 is provided directly behind the vertical plate 2. The control box 5 is fixedly installed at the upper rear of the base 1. An installation box 7 is provided in front of the vertical plate 2. A clamping component 8 is installed inside the installation box 7. A soft pad 9 is glued to the front end of the installation box 7. A fixing box 10 is embedded in the middle of the installation box 7. Guide grooves 11 are opened inside the upper and lower ends of the fixing box 10. A T-shaped rod 12 is slidably installed on the inner side of the fixing box 10. The front end of the middle part of the T-shaped rod 12 is glued to the soft pad 9.
[0028] Based on the above structure, a limiting groove 3 is opened inside the vertical plate 2, and diagonal braces 6 are symmetrically provided on the left and right sides of the control box 5. The two ends of the diagonal braces 6 are welded and fixed to the base 1 and the vertical plate 2 respectively. The base 1, the vertical plate 2 and the diagonal braces 6 form a triangular structure.
[0029] In this embodiment, the overall stability of the device during operation can be improved by setting the diagonal brace 6.
[0030] Based on the above structure, the height adjustment component 4 includes a servo motor 41, a long lead screw 42, and a movable block 43. The servo motor 41 is fixedly installed on the outer wall of the top rear end of the vertical plate 2. The output end of the servo motor 41 is fixedly connected to the long lead screw 42, and the movable block 43 is threaded on the outer side of the long lead screw 42.
[0031] Based on the above structure, the movable block 43 slides in the limiting groove 3, and the mounting box 7 is fixedly installed at the front end of the movable block 43.
[0032] In this embodiment, by starting the servo motor 41 to control the rotation of the long lead screw 42, the movable block 43 can be controlled to drive the mounting box 7 to move vertically and stably along the limiting groove 3, thereby facilitating the lifting and installation of the refrigerator door.
[0033] Based on the above structure, the clamping assembly 8 includes a first crossbar 81, a second crossbar 82, a clamping plate 84, a rubber pad 85, and a multi-section electric push rod 86. The first crossbar 81 and the second crossbar 82 are symmetrically arranged about the central axis of the mounting box 7. The two second crossbars 82 are located between the two first crossbars 81. The ends of the first crossbar 81 and the second crossbar 82 that are far apart from each other are fixedly connected to the clamping plate 84. The front ends of the two clamping plates 84 that are close to each other are inlaid with rubber pads 85. The two multi-section electric push rods 86 are respectively fixedly installed on the left and right outer walls of the fixing box 10. The telescopic ends of the two multi-section electric push rods 86 are respectively fixedly connected to the two clamping plates 84.
[0034] In this embodiment, by activating two multi-section electric push rods 86, it is easy to control the two clamping plates 84 to move synchronously and move closer to each other, thereby facilitating the clamping of the refrigerator door.
[0035] Based on the above structure, the first crossbar 81 and the second crossbar 82 have the same shape and size, and both of them have through grooves 83 inside their respective ends that are close to each other. The through grooves 83 include inclined sections and straight sections, and the straight sections are connected to the inclined sections.
[0036] Based on the above structure, the upper and lower ends of the T-shaped rod 12 pass through the guide groove 11 and are guided to slide inside the through groove 83.
[0037] In this embodiment, while the two clamping plates 84 drive the first crossbar 81 and the second crossbar 82 to move, the inclined section of the internal through groove 83 of the two plates can squeeze and push the T-shaped rod 12 to move backward along the guide groove 11, thereby pulling the middle part of the soft pad 9 toward the fixed box 10, so that a sealed cavity with air pressure lower than normal is formed between the soft pad 9 and the surface of the refrigerator door, which is convenient for adsorption and positioning of the refrigerator door, and achieves a dual positioning effect for the refrigerator door.
[0038] The working principle of this utility model is as follows:
[0039] In use, first place the refrigerator door to be installed on the front and above the base 1, and at the same time, make sure the smooth outer surface of the refrigerator door is tightly attached to the soft pad 9. Then, start the two multi-section electric push rods 86 on the left and right at the same time to control the two clamping plates 84 to move synchronously and move closer to each other, so as to clamp and position the refrigerator door. The rubber pad 85 can increase the friction between the clamping plate 84 and the refrigerator door, making the clamping more stable. When the two clamping plates 84 drive the first crossbar 81 and the second crossbar 82 to move, the inclined section of the through groove 83 inside the two can squeeze and push the T-shaped rod 12 to move backward along the guide groove 11, so that the middle part of the soft pad 9 is pulled towards the fixing box 10, so that a sealed cavity with air pressure lower than normal is formed between the soft pad 9 and the surface of the refrigerator door, which is convenient for adsorption and positioning of the refrigerator door, achieving a dual positioning effect for the refrigerator door. This can ensure the stability of the refrigerator door during the subsequent lifting and installation process. Moreover, when the end of the T-shaped rod 12 enters the straight section of the through groove 83, the movement of the first crossbar 81 and the second crossbar 82 can keep the T-shaped rod 12 stationary.
[0040] After securing the refrigerator door firmly, the device and refrigerator door can be pushed to one side of the production line. Figure 6 As shown in the diagram, the servo motor 41 is then started, and the rotation of the long screw 42 controls the movable block 43 to drive the mounting box 7 and the refrigerator door it holds to move vertically up and down along the limiting groove 3 in sync. This makes it easy to raise the refrigerator door to a suitable installation position, and then a single person can install it. This not only saves manpower but also speeds up the installation process and effectively improves the assembly efficiency of the refrigerator.
[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
