Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment manufacturing, and in particular to a rear mounting system for refrigeration equipment. Background Technology

[0002] Currently, in the production process of refrigeration equipment (such as refrigerators), the installation of the back panel is usually done manually. On traditional refrigerator pre-assembly lines, back panel installation requires at least two workers. First, the worker manually places the refrigerator back panel into the slot of the pre-assembly unit, then uses tools such as a rubber mallet to tap the back panel to ensure it is fully embedded in the slot, completing the installation. However, this manual installation method has the following problems:

[0003] First, the back of a refrigerator is usually quite large, making it difficult to move and position. This requires multiple workers to work together, resulting in high labor intensity and low production efficiency. Second, manually tapping the back can easily damage the surface of the pre-assembled cabinet or the pre-assembled internal components, affecting product quality. In addition, the positioning accuracy of manual operation is low, making it difficult to ensure the consistency and stability of installation.

[0004] Therefore, there is an urgent need for a system that can automate the installation of refrigeration equipment on the back to improve production efficiency, reduce labor intensity, and ensure product quality. Utility Model Content

[0005] To address the installation problem of the back panel of refrigeration equipment in commonly used technologies, the purpose of this utility model is to provide a back panel installation system for refrigeration equipment that enables automated installation, improves production efficiency, reduces labor intensity, and ensures product quality.

[0006] To achieve the above-mentioned utility model objectives, one embodiment of this utility model provides a rear mounting system for a refrigeration device. The refrigeration device includes a rear panel and a pre-installed housing. The rear mounting system includes: A positioning mechanism is configured to position the pre-assembled box. A transfer mechanism is configured to move the back to align with the pre-assembled box on the positioning mechanism; The striking mechanism includes multiple striking units mounted on the transfer mechanism and configured to apply force to the backrest to insert it into a slot in the pre-assembled box when the backrest is aligned with the pre-assembled box.

[0007] As a further improvement of this utility model, the back is rectangular, and the striking mechanism includes four striking units, which are arranged at the four corners of the back to ensure uniform application of force during installation.

[0008] As a further improvement of this utility model, the back mounting system also includes a detection mechanism for detecting whether the back is fully inserted into the slot.

[0009] As a further improvement of this utility model, the detection mechanism includes at least one pair of photoelectric probes arranged opposite each other. When the back is fully inserted into the slot, the optical path between the at least one pair of photoelectric probes is connected. When the back is not fully inserted into the slot, the optical path between the at least one pair of photoelectric probes is blocked by the back.

[0010] As a further improvement of this utility model, the transfer mechanism includes a three-axis moving module, a first flipping module and a second flipping module. The three-axis moving module moves the back in a straight line, the first flipping module rotates the back to be parallel to the direction of insertion into the pre-assembled box, and the first flipping module rotates the back to be aligned with the slot of the pre-assembled box.

[0011] As a further improvement of this utility model, the transfer mechanism further includes a pickup module, which includes multiple adsorption units that adsorb the back to enable the transfer mechanism to move the back.

[0012] As a further improvement of this utility model, the positioning mechanism includes a pair of positioning units arranged opposite to each other. Each positioning unit includes a longitudinal moving module, a pair of clamping modules and a pair of clamping plates. The longitudinal moving module and the lateral moving module adjust the clamping module to drive the pair of clamping plates to clamp and adapt to the position of the pre-assembled box.

[0013] As a further improvement of this utility model, the striking unit is configured as a cylinder, and multiple cylinders are independently controlled. The output end of the cylinder acts on the back to apply an installation force.

[0014] As a further improvement of this utility model, the rear mounting system also includes a transmission mechanism, which supports the pre-assembled box and moves it to the positioning mechanism.

[0015] As a further improvement of this utility model, the back mounting system also includes a tooling mechanism, in which multiple backs are placed, and the transfer mechanism moves the backs in the tooling mechanism to be aligned with the pre-assembled box on the positioning mechanism.

[0016] Compared with commonly used technologies, this utility model has the following beneficial effects: The back-mounting system of this refrigeration equipment automatically moves the back to the position aligned with the pre-assembled box through a transfer mechanism, and automatically inserts the back using a tapping mechanism, replacing the traditional manual handling and tapping operations. This significantly reduces manual intervention, improves the automation level and production efficiency of the production line, and avoids surface scratches or damage to pre-assembled parts that may be caused by manual tapping. This improves the product quality and consistency of the refrigeration equipment. Furthermore, by eliminating the need for manual handling and support, it greatly reduces the labor intensity of workers, improves the safety and comfort of operation, and provides an efficient and reliable solution for the production of refrigeration equipment.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0019] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0020] One embodiment of this utility model provides a rear-mounting system for refrigeration equipment, which achieves precise installation of the rear-mounting unit through automated operation, solving the shortcomings of traditional manual installation such as low efficiency, high labor intensity, and easy product quality problems.

[0021] The refrigeration equipment in this embodiment can be a refrigerator, freezer, upright refrigerator, wine cabinet, etc. The following embodiment can be described using a refrigerator as an example.

[0022] like Figure 1 As shown, the refrigeration equipment includes a cabinet and a door. The cabinet includes a back panel 50 and a pre-assembled cabinet 40. The pre-assembled cabinet 40 has a slot. The back panel 50 needs to be inserted into the slot and fixed relative to the pre-assembled cabinet 40 to complete the assembly of the cabinet.

[0023] To clearly illustrate the position and orientation described in this embodiment, in this embodiment, the back panel 50 is defined to be installed with the pre-assembled housing 40 from top to bottom, and the slot opening of the pre-assembled housing 40 is set upward. The orientation in this embodiment can also be referenced to the direction of gravity, that is, the direction of gravity is down and the opposite direction is up, so that the pre-assembled housing 40 is located on a horizontal plane when installed.

[0024] The refrigeration equipment back-mounting system 100 of this embodiment is used to automatically complete the installation of the back-mounting system 50 and the pre-assembled housing 40 on the refrigeration equipment production line, such as... Figure 1 As shown, the rear mounting system 100 includes the following core components: a positioning mechanism 30, a transfer mechanism 20, and a striking mechanism 26. These components work together to achieve precise positioning, handling, and installation of the rear mount 50 through an automated process.

[0025] The overall workflow of the back-mounting system 100 is as follows: the positioning mechanism 30 fixes the refrigerator pre-installed cabinet 40, the transfer mechanism 20 moves the back 50 from the storage position to be aligned with the pre-installed cabinet 40, and the striking mechanism 26 applies force to insert the back 50 into the slot of the pre-installed cabinet 40, thereby completing the installation.

[0026] Specifically, the positioning mechanism 30 is installed on the pre-assembly line of the refrigerator production line to accurately position the refrigerator pre-assembly box 40, so as to ensure that the back panel 50 is precisely aligned with the slot of the pre-assembly box 40 during installation.

[0027] The transfer mechanism 20 is configured to move the back 50 to align with the pre-assembled case 40 on the positioning mechanism 30. The transfer mechanism 20 replaces the arduous manual handling of the back 50 with automated handling, significantly improving production efficiency.

[0028] The striking mechanism 26 includes multiple striking units 26a, which are mounted on the transfer mechanism 20 and configured to apply force to the back 50 when it is aligned with the pre-assembled housing 40, thereby inserting it into a slot in the pre-assembled housing 40. Each striking unit 26a consists of a pneumatic cylinder and a striking head. By adjusting the output pressure of the cylinder, the striking head pushes the edge of the back 50 with appropriate force, gradually inserting it into the slot in the pre-assembled housing 40.

[0029] The rear mounting system 100 significantly shortens the installation cycle of the rear 50 through automated operation, eliminates the need for manual handling and hammering, reduces the physical exertion of workers, improves the safety and comfort of the working environment, effectively improves the overall efficiency of the production line, and is suitable for the needs of various refrigeration equipment production lines, with high flexibility and versatility.

[0030] In one embodiment, such as Figure 2 and 3 As shown, the back 50 is rectangular, and the striking mechanism 26 includes four striking units 26a, which are arranged at the four corners of the back 50 to ensure that the force is applied evenly during installation.

[0031] Each striking unit 26a consists of a pneumatic cylinder and a striking head, and is mounted on the end effector of the transfer mechanism 20. The four striking units 26a are arranged at the four corners of the back 50, respectively.

[0032] Each striking unit 26a has a cylinder supplied with air by an air pump. The output end of the cylinder is connected to a striking head, which is made of a high-strength but flexible cushioning material to protect the surface of the back 50 when force is applied. The striking units 26a are arranged in a rectangular pattern to match the geometry of the back 50, ensuring that the applied force is evenly distributed at the four corners of the back 50.

[0033] During installation, the transfer mechanism 20 moves the backrest 50 to align with the slot of the pre-installed housing 40, and then the four cylinders of the striking mechanism 26 are activated simultaneously or in a predetermined sequence. The control system precisely controls the output force of each cylinder via a pneumatic regulator, based on the size and material of the backrest 50, to ensure that the backrest 50 is smoothly inserted into the slot without deformation or surface damage. The striking head provides sufficient thrust to the backrest 50 while avoiding localized stress concentration. The striking process is performed in stages, applying a brief pulse of force each time until the backrest 50 is fully embedded in the slot. The control system monitors the cylinder stroke via sensors to ensure synchronized action of the four striking units 26a, maintaining uniform force.

[0034] The placement of four striking units 26a at the four corners of the back panel 50 significantly improves the stability of the installation process. By applying evenly distributed force, the back panel 50 can be smoothly and accurately inserted into the slot of the pre-assembled housing 40, avoiding tilting or jamming caused by uneven force. Compared to traditional manual striking methods, the striking mechanism 26 in this embodiment increases the installation success rate and effectively prevents scratches on the surface of the back panel 50 or damage to the pre-assembled housing 40, thus improving the stability and consistency of product quality. The synchronous operation of the four striking units 26a also shortens the installation time per cycle, further improving production efficiency.

[0035] In one embodiment, such as Figure 4 and 5 As shown, the rear mounting system 100 also includes a detection mechanism 32, which is used to detect whether the rear mount 50 is fully inserted into the slot.

[0036] The detection mechanism 32 includes a set of sensor components and a signal processing module, mounted on a fixed frame near the slot of the pre-installed housing 40. The sensor components can detect the position of the back panel 50 relative to the slot, determining whether the back panel 50 is fully embedded in the slot. The signal processing module is connected to the system's control unit, feeding back the detection results to the control system so that operation can be stopped or an alarm can be issued in a timely manner when an installation abnormality is detected. The configuration of the detection mechanism 32 ensures the reliability of the installation process and avoids quality problems caused by incomplete installation.

[0037] The detection mechanism 32 employs a non-contact detection method (such as a photoelectric or laser sensor), covering the critical area where the back cover 50 is inserted. The control system presets a position threshold for when the back cover 50 is fully inserted (for example, when the slot depth is 5 cm, the edge of the back cover 50 should be flush with the bottom of the slot). When the sensor detects that the back cover 50 has reached the predetermined position, the signal processing module generates an "installation complete" signal, notifying the control system to stop the tapping mechanism 26; if the back cover 50 is not fully inserted, the system will trigger an alarm, prompting the operator to check or re-perform the installation.

[0038] The introduction of the inspection mechanism 32 significantly improves the reliability and quality control level of the backrest 50 installation. By monitoring the insertion status of the backrest 50 in real time, the system can promptly detect incomplete installation, avoiding potential quality defects in subsequent assembly processes and further improving the installation pass rate.

[0039] like Figure 5 As shown, the detection mechanism 32 includes at least one pair of photoelectric probes 32a arranged opposite each other. When the back 50 is fully inserted into the slot, the optical path between the at least one pair of photoelectric probes 32a is connected. When the back 50 is not fully inserted into the slot, the optical path between the at least one pair of photoelectric probes 32a is blocked by the back 50.

[0040] In this embodiment, the detection mechanism 32 uses a photoelectric probe 32a as the core detection element to accurately determine whether the back cover 50 is fully inserted into the slot of the pre-assembled housing 40. The photoelectric probe 32a includes a transmitter and a receiver, which are mounted in pairs on the fixed frames on both sides of the slot to form one or more optical paths, covering the key positions of the insertion path of the back cover 50. The transmitter of the photoelectric probe 32a emits an infrared or visible light beam, and the receiver detects whether the light beam is received.

[0041] When the backplate 50 is fully inserted into the slot, its edge reaches the bottom of the slot and does not obstruct the light path, allowing the photoelectric probe 32a to detect the continuity of the light path. When the backplate 50 is not fully inserted, part of its structure obstructs the light path, preventing the receiver from receiving the light beam. The detection result is transmitted to the control system via the signal processing module to control the installation process or issue an alarm.

[0042] The optical path height is set to be flush with or slightly higher than the bottom of the slot by 0.5-1 mm to ensure that the optical path is connected only when the back cover 50 is fully inserted. During installation, as the tapping mechanism 26 pushes the back cover 50 into the slot, the photoelectric probe 32a continuously monitors the optical path status. If the back cover 50 is fully inserted, the control system receives an optical path connection signal, stops the tapping action, and proceeds to the next step; if the optical path is blocked, the system pauses operation and issues an alarm via the display screen or buzzer, prompting the operator to check the position of the back cover 50.

[0043] Compared to traditional manual visual inspection, the photoelectric probe 32a reduces manual intervention time and lowers the workload of operators. At the same time, the detection accuracy of the photoelectric probe 32a ensures the precision of the backplate 50 installation, avoiding subsequent assembly problems caused by incomplete insertion, and further improving the installation pass rate.

[0044] In one embodiment, such as Figures 1-3 As shown, the transfer mechanism 20 includes a three-axis moving module 21, a first flipping module 23, and a second flipping module 24. The three-axis moving module 21 moves the back 50 linearly, and the first flipping module 23 rotates the back 50 to be parallel to the direction of insertion into the pre-assembled box 40. The first flipping module 23 rotates the back 50 to be aligned with the slot of the pre-assembled box 40.

[0045] The three-axis motion module 21 consists of a robotic arm body mounted on a track system, equipped with linear guides and servo motors in the X, Y, and Z directions, enabling the back 50 to move linearly in space.

[0046] The first flipping module 23 is installed at the end of the robotic arm and is used to rotate the back 50 about a single axis, for example, to flip the back 50 from a vertical state to a horizontal state.

[0047] In this embodiment, the first flipping module 23 includes a linear cylinder, a gear, and a rack. The linear cylinder drives the rack to move linearly, which in turn drives the gear meshing with the rack to rotate, thereby achieving flipping.

[0048] In other embodiments, the first flipping module 23 can also be flipped by a rotary motor and a connecting arm.

[0049] The second flipping module 24 consists of another rotary motor and auxiliary connectors, which realizes the rotation of the back 50 on the horizontal plane and ensures that the insertion edge of the back 50 is precisely aligned with the entrance of the slot.

[0050] The three-axis moving module 21, the first flipping module 23, and the second flipping module 24 work together to solve the alignment problem of the back cover 50 in complex spatial directions, adapting to the installation requirements of different models of this refrigeration equipment. They provide multi-angle and multi-position adjustment capabilities to accommodate the installation needs of different models of the back cover 50. This eliminates the physical exertion of manually handling the back cover 50, reduces the labor intensity of workers, and improves the safety and operational comfort of the production line.

[0051] In one embodiment, such as Figure 2 and 3 As shown, the transfer mechanism 20 also includes a bracket 25 and a pickup module 27. The bracket 25 is connected to the output end of the second flipping module 24, and the pickup module 27 and multiple tapping units 26a are fixed on the bracket 25.

[0052] The pickup module 27 includes multiple adsorption units 27a, which adsorb the back 50 to move the back 50 by the transfer mechanism 20.

[0053] The adsorption unit 27a employs a vacuum suction cup design. Each suction cup generates negative pressure through a vacuum pump and air path system to adhere to the surface of the back 50. The number of suction cups is configured according to the size and weight of the back 50, typically 4 to 12, distributed on the support frame in a rectangular or circular array to ensure uniform distribution of adsorption force. The suction cups are made of flexible silicone, which can firmly adhere to the smooth surface of the back 50 while avoiding scratches or deformation.

[0054] After the adsorption unit 27a contacts the back 50, the vacuum pump maintains a negative pressure state to ensure that the back 50 does not slip or shift during movement. The transfer mechanism 20 then moves the back 50 above the pre-assembled box 40. After alignment, the control system shuts off the vacuum pump, the suction cup releases the back 50, and the striking unit 26a is ready to operate.

[0055] In one embodiment, such as Figure 4 and 5As shown, the positioning mechanism 30 includes a pair of positioning units 31 arranged opposite to each other. Each positioning unit 31 includes a longitudinal moving module 311, a pair of clamping modules 313 and a pair of clamping plates 314. The longitudinal moving module 311 and the transverse moving module 312 adjust the clamping module 313 to drive the pair of clamping plates 314 to clamp and adapt to the position of the pre-assembled box 40.

[0056] The positioning mechanism 30 is used to fix the pre-assembled housing 40, ensuring its stability and precise alignment during the installation process on the back 50. A pair of opposing positioning units 31 are respectively located on both sides of the pre-assembly line. The longitudinal movement module 311 uses a cylinder or a servo motor with a linear guide to control the positioning unit 31 to move vertically; the lateral movement module 312 also uses a cylinder or a servo motor with a linear guide, with its extension end moving closer to or further away from the pre-assembled housing 40. The ends of a pair of clamping modules 313 are connected to clamping plates 314, driving the clamping plates 314 to clamp the side walls of the pre-assembled housing 40. The clamping modules 313 are driven by cylinders to achieve opening and closing actions, and the clamping force is adjustable to accommodate pre-assembled housings 40 of different sizes.

[0057] The positioning unit 31 of the positioning mechanism 30 significantly improves the flexibility and accuracy of fixing the pre-assembled housing 40. The coordinated adjustment of the longitudinal and lateral movement modules 312 enables the positioning mechanism 30 to adapt to pre-assembled housings 40 of different sizes. The longitudinal movement module 311 matches different width requirements, the lateral movement module 312 matches different height requirements, and a pair of clamping modules 313 matches different length requirements, thus covering the needs of various sizes of refrigeration equipment.

[0058] In one embodiment, the striking unit 26a is configured as a cylinder, with multiple cylinders controlled independently, and the output end of the cylinder acts on the back 50 to apply an installation force.

[0059] Each striking unit 26a uses a pneumatic cylinder as a driving element and is mounted on a bracket 25 of the transfer mechanism 20. The cylinder is supplied with air through an air pump and air circuit system, and its output end is connected to the striking head. The striking head acts directly on the edge area of ​​the back 50 to apply installation force.

[0060] Multiple cylinders (e.g., four in this embodiment, matching the rectangular structure of the back 50) are controlled by independent solenoid valves, and the thrust of each cylinder can be individually adjusted to accommodate back 50s of different sizes and materials. The contact surface of the striking head is made of flexible polyurethane material to ensure uniform force application and prevent damage to the surface of the back 50. The stroke range of the cylinders covers the insertion depth requirements of the slots.

[0061] During installation, once the back panel 50 is aligned with the slot of the pre-installed cabinet 40 by the transfer mechanism 20, the control system activates the solenoid valve of the striking unit 26a, and the air pump supplies air to the cylinders to generate thrust. The action of each cylinder is independently programmed by the control system, allowing adjustment of the output force based on the size of the back panel 50 and the resistance of the slot. For example, for thicker back panel 50 material, the cylinder applies a higher initial thrust, which is then gradually reduced to achieve smooth insertion. The striking process uses pulsed force application to ensure that the back panel 50 gradually embeds into the slot without deformation due to excessive instantaneous force. After installation, the cylinders reset, ready for the next operation. This installation method ensures consistent refrigerator product quality.

[0062] In one embodiment, such as Figure 1 , 4 As shown in Figure 5, the rear mounting system 100 also includes a transmission mechanism 60, which supports the pre-installed housing 40 and moves it to the positioning mechanism 30.

[0063] The transfer mechanism 60 transports the pre-assembled boxes 40 from the upstream process of the production line to the working area of ​​the positioning mechanism 30, providing stable support. The transfer mechanism 60 consists of a conveyor belt system, a support frame, and a drive unit. The transfer mechanism 60 can accommodate pre-assembled boxes 40 of different sizes. The transfer mechanism 60 is connected to the control system and can automatically adjust its moving speed and stopping position according to the production cycle.

[0064] like Figure 1 As shown, the rear mounting system 100 also includes a tooling mechanism 10, in which multiple rear mounts 50 are placed. The transfer mechanism 20 moves the rear mounts 50 in the tooling mechanism 10 to be aligned with the pre-installed housing 40 on the positioning mechanism 30.

[0065] The tooling mechanism 10 adopts a mobile tooling cart design. The cart body is constructed of a steel frame and equipped with multiple storage compartments. Each storage compartment can hold one backpack 50. The storage compartments are equipped with partitions to ensure that the backpacks 50 are placed vertically and do not touch each other. After the tooling mechanism 10 is moved into position, it is convenient for the transfer mechanism 20 to grab the backpack 50.

[0066] Compared with commonly used technologies, this embodiment has the following advantages: The rear mounting system 100 of this refrigeration equipment automatically moves the back panel 50 to a position aligned with the pre-assembled housing 40 via the transfer mechanism 20, and automatically inserts the back panel 50 using the tapping mechanism 26. This replaces the traditional manual handling and tapping operations, significantly reducing human intervention, improving the automation level and production efficiency of the production line, and avoiding surface scratches or damage to pre-assembled parts that may be caused by manual tapping. This improves the product quality and consistency of the refrigeration equipment. Furthermore, by eliminating the need for manual handling and support, it greatly reduces the labor intensity of workers, improves the safety and comfort of operation, and provides an efficient and reliable solution for the production of refrigeration equipment.

[0067] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0068] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
