Abstract
Description
Technical Field
[0001] This invention relates to the field of microchannel heat exchanger technology, and more particularly to an automated core assembly production process. Background Technology
[0002] A microchannel heat exchanger is a device used for heat exchange. It mainly consists of two manifolds, a flat tube connecting the two manifolds, and fins between the flat tubes. The flat tube is provided with microchannels for refrigerant to pass through. This microchannel heat exchanger is widely used in the manufacture of condensers, evaporators, etc.
[0003] In the existing core assembly process, the fabrication and bundling are carried out separately, which cannot be done in a continuous production process. In particular, for large-sized flat tubes and fins, during the process of transferring the fabric to the bundling mechanism, it is easy to cause deformation and loosening of the fins and flat tubes, which affects the normal bundling. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated core assembly production process. This process involves alternating feeding of flat tubes and fins using a flat tube sorting unit, with the flat tubes and fins arranged sequentially and at intervals to achieve continuous automated feeding. Once feeding is complete, the fins and flat tubes are moved to an adjacent binding unit on the same horizontal plane via a core transfer unit, enabling online binding. This reduces the need for long-distance transfer and clamping of the fin and flat tube assembly by the gripping mechanism, and solves the problem of deformation of the fins and flat tubes during core movement before binding.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An automated core assembly production process, characterized by comprising the following steps:
[0007] Flat tube loading: After the vehicle body is full of flat tubes, the vehicle body is moved into the support frame. The gripping device simultaneously grips multiple flat tubes and transfers them to the feeding assembly through the moving frame.
[0008] Fin feeding: The fins formed by the fin forming machine are conveyed to the flat tube sorting unit by the conveyor.
[0009] Fabrication process: The flat tubes are conveyed to the feeding assembly and then to the sorting assembly. The sorting assembly flips the flat tubes one by one and feeds them to the front of the pusher plate. The fins are conveyed between the pusher plate and the flat tubes. The pusher plate pushes the fins and flat tubes forward synchronously, so that the fins and flat tubes are arranged in sequence at intervals.
[0010] Transfer process: The completed fins and flat tubes are transferred to the support plate at the binding unit through the core transfer unit.
[0011] As an improvement, in the flat tube feeding process, the jacking mechanism jacks up the bottom flat tube during the movement of the moving frame, so that the top flat tube is within the grabbing range of the grabbing device.
[0012] As an improvement, in the feeding process, the sorting assembly turns and feeds the flat tubes one by one, and the guide plate is always in contact with the flat tube to guide the flat tube to the support.
[0013] As an improvement, the guide plate is driven by the guide drive assembly to move up and down intermittently, matching the pushing frequency of the push plate.
[0014] As an improvement, in the feeding process, the receiving disc is rotated to turn the flat tubes on the feeding belt from a horizontal state to a vertical state, and then the flat tubes are conveyed to the front of the push plate.
[0015] As an improvement, in the feeding process, the fixed positioning member positions the feeding end of the fins and flat tubes, and the first moving positioning member positions the discharging end of the fins and flat tubes, so that the gap between the fins and flat tubes meets the process requirements.
[0016] As an improvement, in the feeding process, the auxiliary conveying assembly assists in conveying the fins and flat tubes forward, and the upper end surface of the auxiliary conveying assembly is higher than the upper surface of the support plate, and the first moving positioning member is matched to ensure that the surface of the fins and flat tubes is not scratched during conveying and stable forward conveying.
[0017] As an improvement, in the feeding process, the first moving positioning member and the second moving positioning member cooperate to position the finished core body forward and backward, and convey it a distance forward, so that the finished core body can be clamped by the core body transfer unit.
[0018] As an improvement, the transfer process further includes a bundling process: after the wire drawing mechanism pulls the iron wire around the core body, the wire clamping unit cooperates with the wire twisting unit to firmly bundle the core body.
[0019] As an improvement, before the bundling process, it further includes a leveling process: the two groups of transverse moving assemblies drive the leveling assemblies to move outward from the middle, and perform leveling treatment on the upper end surfaces of the fins and flat tubes.
[0020] As an improvement, before the bundling process, it further includes a manifold feeding process: the manifold is installed at both ends of the flat tube by manual or automatic device, so that the manifold, flat tube and fin form a core structure.
[0021] As an improvement, before the bundling process, it further includes a gasket feeding process: the gasket is fed to both ends of the core body, so that the iron wire bundling contact point is located on the gasket.
[0022] As an improvement, in the transferring process, the finished fin and flat tube of the cloth are transferred to the bundling station adjacent to the cloth station by the first and second beams movably arranged, and are bundled on line.
[0023] As an improvement, in the bundling process, the wire drawing mechanism draws the iron wire on the wire feeding unit to lay on the bearing plate and is clamped by the pre-embedded iron wire clamping part, the core body transferring unit carries the whole set of core bodies to the bearing plate on which the iron wire is laid, after the core body positioning unit clamps the core body, the wire drawing mechanism draws the iron wire back to the iron wire clamping unit to clamp the two ends of the iron wire, the shearing unit shears the clamped iron wire, and the wire twisting unit twists the two iron wire heads to firmly bundle the core body.

[0027] (3) The present application sets a guide plate below the receiving disc, so that the flat tube always contacts the guide plate during the falling process, preventing it from falling over. In addition, the setting of the guide driving assembly ensures that the flat tube always contacts the guide plate during the falling process on the support, avoiding the flat tube from falling over and affecting normal cloth distribution.
[0028] (4) The present application realizes the front and rear positioning of the fin and flat tube sorting process by setting the fixed positioning member and the first movable positioning member, and ensures the stability of the fin and flat tube sorting process by using the first movable positioning member, thereby avoiding the phenomenon of increasing the gap between the fin and flat tube, causing the flat tube to fall over and affecting normal production.
