[0002] In the automobile manufacturing process, the heating system is an important component for improving driving and riding comfort, and the heating core, as the core component of the heating system, directly affects the performance of the heating system through its assembly precision and stability.

[0003] In traditional assembly processes, fixing the heater core mainly relies on manual operation or simple mechanical clamps, which presents the following technical problems: During the assembly process, manual operation requires multiple adjustments to the core position, which is time-consuming and makes it difficult to ensure assembly consistency; at the same time, the lack of a synchronous adjustment mechanism makes the core prone to displacement during assembly, leading to difficulties in installing joint components and affecting sealing and heat exchange efficiency.

[0004] Therefore, we propose an automotive heater core assembly device. Summary of the Invention

A cylinder is fixedly mounted on the base, and a pressure plate that cooperates with the core mounting plate is fixedly connected to the telescopic end of the cylinder.

[0007] It also includes: a fixing plate that is fixed to the base, an inclined plate that is slidably fitted on the fixing plate and fixed to the end of the pressure plate, a rotating wheel that is rolled at both ends of the inclined plate, the inner side of the rotating wheel at the bottom position is inclined, a moving rod that is inserted into the core mounting plate is pressed at the edge of the inclined surface of the rotating wheel at the bottom, and a pressing rod that passes through the core mounting plate and locks and fixes the core is rotatably connected between the two moving rods;

The cross-distributed connecting ropes and connecting rods constitute overload protection. When the pressure plate applies pressure close to the core's bearing limit, it automatically limits the downward stroke to avoid deformation and damage. In addition, the mounting groove design on the clamping plate can be seamlessly adapted to the operation of the robotic arm, making the docking of connecting components quick and precise, providing key technical support for the efficient and stable assembly of automotive heater cores.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-10 The present invention provides an automotive heater core assembly device, including a base 1 and a core mounting plate 2 located on the base 1. A cylinder 3 is fixedly installed on the base 1, and a pressure plate 4 that cooperates with the core mounting plate 2 is fixedly connected to the telescopic end of the cylinder 3.

[0032] Before assembly, the core is placed on the core mounting plate 2. Then, the cylinder 3 drives the pressure plate 4 to descend. The pressure plate 4 and the core mounting plate 2 fix the top and bottom of the core, thus fixing the core. Finally, the external robotic arm (robotic arm and other auxiliary equipment are conventional technologies and are not shown in the figure) installs the connector assembly to the edge of the core, thus completing the assembly of the car heater core.

[0033] In the existing technology, during the descent of the pressure plate 4, there is no synchronous adjustment mechanism for adjusting the position of the core, that is, the core located on the core mounting plate 2 cannot be adjusted synchronously to ensure that the fixing and adjustment mechanisms of the pressure plate 4 are synchronized, thereby ensuring the accurate positioning of the fixed car heater core and facilitating the precise installation of subsequent connector components. The specific improvements are as follows:

[0034] The core mounting plate 2 is fixedly connected to a fixing frame 21 with an acute angle structure at its side. An arc plate 22 is rotatably connected to the end of the fixing frame 21. The arc plate 22 and the clamping plate 20 work together to support the core.

[0035] A connecting plate 18 is fixedly connected to the base 1, and a telescopic rod 19 with an internal compression component is fixedly connected to the connecting plate 18. The movable end of the telescopic rod 19 is pressed against the inclined plate 6, and a clamping plate 20 is fixedly connected to the movable rod of the telescopic rod 19.

[0036] When the pressure plate 4 is away from the core mounting plate 2, the clamping plate 20 is away from the core mounting plate 2 in the horizontal direction, which makes it easier to place the core on the core mounting plate 2. One end of the core presses against the arc plate 22, causing the arc plate 22 to rotate. The bottom of the arc plate 22 is attached to the fixing frame 21, and the top of the arc plate 22 presses against and restricts the core from moving upward, thereby initially maintaining the position of the core.

[0037] Meanwhile, the clamping plate 20 located on the other side of the core does not contact the core at this time and cannot fix the horizontal position of the core.

[0038] The starting cylinder 3, this application also includes a fixing plate 5 that is fixed to the base 1, an inclined plate 6 that is fixed to the end of the pressure plate 4 is slidably fitted on the fixing plate 5, and a rotating wheel 7 is rolled at both ends of the inclined plate 6, with the inner side of the rotating wheel 7 located at the bottom position being set with an inclined surface 8.

[0039] The cylinder 3 drives the pressure plate 4 to move downward, thereby driving the connecting rod 13 and the inclined plate 6 to move vertically downward along the fixed plate 5. The inclined plate 6 is fixedly connected to the outside of the sliding plate 14. The fixed plate 5 has a sliding groove 15 that slides with the sliding plate 14. The sliding groove 15 and the sliding plate 14 are vertically distributed, thereby ensuring that the inclined plate 6 and the pressure plate 4 maintain vertical movement.

[0040] It is worth noting that: the top and bottom of the inclined plate 6 are both fixedly connected with vertically distributed toothed plates 16 that pass through the base 1. The two toothed plates 16 on the inclined plate 6 are distributed in opposite directions, and the rotating wheel 7 meshes with the toothed plates 16.

[0041] The downward-moving inclined plate 6 drives the two toothed plates 16 to move vertically downwards, thereby causing the two rotating wheels 7 to rotate on the fixed plate 5 (the rotating wheels 7 are preferably gears). The two rotating wheels 7, which are distributed vertically, rotate in opposite directions. The arrangement of the rotating wheels 7 and gears makes the downward movement of the pressure plate 4 more stable. On the other hand, in conjunction with the connecting rope 12, it prevents the pressure plate 4 from moving downwards excessively, which could cause damage to the core. The specific methods of prevention are as follows:

[0042] The rotating wheel 7 is fixedly connected to a rotating shaft 11 that is rotatably connected to the fixed plate 5. A connecting rope 12 is rotatably connected between the two rotating shafts 11. The connecting rope 12 is crisscrossed in the middle. Two connecting rods 13 are fixedly connected between the end of the pressure plate 4 and the inclined plate 6. The connecting rope 12 is located between the two connecting rods 13, and the connecting rope 12 is in abutting contact with the connecting rods 13.

[0043] The two rotating wheels 7, which are distributed vertically, rotate in opposite directions, thereby making the connecting rope 12 movable. The movable connecting rope 12 ensures the synchronous rotation of the two rotating wheels 7 (although the rotation directions are opposite), ensuring the smooth up and down sliding of the inclined plate 6. On the other hand, although the connecting rope 12 is movable, the connecting rope 12 (non-elastic rope) maintains the stable transmission at this position.

[0044] The pressure plate 4 moves downward, causing the two connecting rods 13 to move downward synchronously. When the pressure plate 4 fully contacts and presses the core firmly on the core mounting plate 2, the two connecting rods 13 contact the inclined connecting rope 12, thereby preventing the pressure plate 4 from moving further downward and avoiding excessive pressure from the pressure plate 4, which could damage the core.

[0045] When the pressure plate 4 is not lowered, the movable end of the telescopic rod 19 presses against the toothed plate 16. At this time, the clamping plate 20 is away from the side of the core, and the core is easy to put into the core mounting plate 2.

[0046] As the pressure plate 4 descends, the toothed plate 16 and the inclined plate 6 move downwards, and the movable end of the telescopic rod 19 slides against the inclined plate 6. Since the inclined plate 6 has an inclined structure on both sides, under the action of the compression component, the movable rod of the telescopic rod 19 moves horizontally towards the core, thereby pressing the clamping plate 20 against the edge of the core until the movable end of the telescopic rod 19 disengages from the inclined plate 6, and the clamping plate 20 fits tightly against the edge of the core.

[0047] The clamping plate 20 has multiple mounting slots 25, which are used to connect and install the core's connecting components to the core. The diameter of the mounting slots 25 is larger than that of the core's connecting components. When the clamping plate 20 is tightly attached to the edge of the core, the core is also firmly fixed between the core mounting plate 2 and the pressure plate 4. At this time, the mounting hole position corresponds to the reserved hole position of the core (the reserved hole position of the core facilitates the installation of the core's connecting components), making it easy to install the connecting components through the mounting holes to the reserved holes of the core.

[0048] In this application, a movable rod 9 inserted into the core mounting plate 2 is pressed against the edge of the inclined surface 8 of the bottom rotating wheel 7. A pressing rod 10 that passes through the core mounting plate 2 and locks the core is rotatably connected between the two movable rods 9. A compression spring 23 is hung between the ends of the two movable rods 9. A hinge rod 24 is hinged between the movable rod 9 and the pressing rod 10.

[0049] When the rotating wheel 7 at the bottom rotates, the rotating shaft 11 is synchronously connected to the core mounting plate 2. Since the inner side of the rotating wheel 7 is an inclined surface 8, the rotating wheel 7 presses against the moving rod 9. With the action of the compression spring 23, the moving rod 9 moves horizontally back and forth along the core mounting plate 2, thereby driving the hinge rod 24 to rotate. This causes the pressing rod 10, which always maintains a horizontal state, to move upward and get into the gap of the core (the middle part of the core is composed of multiple pipes, between two adjacent pipes), thereby further completing the fixation of the core.

[0050] It is worth noting that: only after the end of the telescopic rod 19 is disengaged from the inclined plate 6, and the clamping plate 20 is pressed tightly against the side of the core by the action of the compression member, does the pressing rod 10 then get into the gap of the core.

[0051] The outer surface of the rotating shaft 11 presses against the moving rod 9 to avoid operational conflicts, and the cooperation between the rotating shaft 11 and the moving rod 9 also ensures the horizontal position of the moving rod 9.

[0052] The inclined plate 6 has arc-shaped grooves 17 at its top and bottom. The rotating wheel 7 is in abutting fit with the arc-shaped grooves 17. When the inclined plate 6 moves to the bottom position, the cooperation between the arc-shaped grooves 17 and the rotating wheel 7 prevents the inclined plate 6 from moving further down.

[0053] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
