[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] See Figure 1 and Figure 2This utility model provides an evaporator inlet and outlet pipe assembly device for assembling an inlet pipe 1 and an outlet pipe 2 to an evaporator core 3. The evaporator core 3 includes a manifold (not shown in the figure). The evaporator inlet and outlet pipe assembly device includes a base 4, a core positioning component 5, a pipe positioning component 6, a press-in drive component 7, and a riveting component 8. The core positioning component 5 is used to limit the position of the evaporator core 3 on the base 4; the pipe positioning component 6 is used to limit the position of the inlet pipe 1 and the outlet pipe 2 on the base 4. Both the core positioning component 5 and the pipe positioning component 6 are disposed on the base 4; the press-in drive component 7 is connected to both the inlet pipe 1 and the outlet pipe 2, and is used to drive the inlet pipe 1 and the outlet pipe 2 to be inserted into the corresponding manifold respectively; the riveting component 8 includes a riveting drive component 81 and a rivet pin 82. The riveting drive component 81 is connected to the rivet pin 82, and is used to rivet the inlet pipe 1 to the corresponding manifold and the outlet pipe 2 to the corresponding manifold.

[0029] In this embodiment, the evaporator core 3 has two manifolds, which correspond to the inlet pipe 1 and the outlet pipe 2, respectively. The pressing drive 7 is a pressing cylinder, and the output end of the pressing cylinder is connected to the side wall of the inlet pipe 1 and the outlet pipe 2 to press the inlet pipe 1 and the outlet pipe 2 inserted into the corresponding manifolds to the manifolds, thereby improving the connection stability. The riveting drive 81 can drive the rivet pin 82 to move closer to the inlet pipe 1 or the outlet pipe 2 to rivet the inlet pipe 1 or the outlet pipe 2 sleeved on the corresponding manifold, thereby achieving a fixed connection between the inlet pipe 1 and the outlet pipe 2 and their corresponding manifolds.

[0030] Thus, the base 4 provides stable support for the evaporator core 3, inlet pipe 1, outlet pipe 2, core positioning assembly 5, pipe positioning assembly 6, press-in drive 7, and riveting assembly 8. The core positioning assembly 5 fixes the position of the evaporator core 3, thereby fixing the position of the manifold. The pipe positioning assembly 6 positions the inlet pipe 1 and outlet pipe 2 to the assembly position. The press-in drive 7 presses the inlet pipe 1 and outlet pipe 2 into their respective manifolds. Under the action of the riveting drive 81, the rivet pin 82 rivets the inlet pipe 1 or outlet pipe 2, making the connection between the inlet pipe 1 and the corresponding manifold, and the connection between the outlet pipe 2 and the corresponding manifold, recessed, thus achieving the riveting of the inlet pipe 1 and the corresponding manifold, and the riveting of the outlet pipe 2 and the corresponding manifold. This reduces manual operation, avoids localized stress concentration on the inlet pipe 1 and outlet pipe 2, and improves the press-fitting effect.

[0031] See Figure 1In some embodiments, the core positioning assembly 5 includes a first positioning member 51, a second positioning member 52, and a limiting block 53. The first positioning member 51 and the second positioning member 52 are located on one side of the evaporator core 3, and the limiting block 53 is located on the other side of the evaporator core 3. The first positioning member 51, the second positioning member 52, and the limiting block 53 are all engaged with the evaporator core 3 to limit the position of the evaporator core 3. Further, in some embodiments, the first positioning member 51 and the second positioning member 52 are arranged obliquely.

[0032] In this embodiment, the first positioning member 51 is a first positioning block, which is engaged with the upper left corner of the evaporator core 3. The second positioning member 52 is a second positioning block, which is engaged with the lower left corner of the evaporator core 3. The limiting block 53 is engaged with the upper right corner of the evaporator core 3 (that is, the position where the evaporator core 3 is located). The limiting block 53 is fixedly installed on the base 4. The core positioning assembly 5 also includes a pushing cylinder 54. There are two pushing cylinders 54. The output ends of the two pushing cylinders 54 are respectively connected to the first positioning block and the second positioning block to push the first positioning block and the second positioning block to engage the evaporator core 3 and engage the evaporator core 3 with the limiting block 53, thereby fixing the evaporator core 3.

[0033] The output end of the push cylinder 54 connected to the first positioning block moves in a direction parallel to the length direction of the base 4, and the output end of the push cylinder 54 connected to the second positioning block moves in a direction oblique to the length direction of the base 4, so that the evaporator core 3 is pushed to the upper right and engaged with the limiting block 53.

[0034] Thus, the first positioning block, the second positioning block, and the limiting block 53 respectively engage with the upper left corner, lower left corner, and upper right corner of the evaporator core 3 to limit the relative position of the evaporator core 3 and the base 4, so that the evaporator core 3 can remain stable when the liquid inlet pipe 1 and the liquid outlet pipe 2 are assembled into the manifold. This allows the pressing cylinder to accurately press the liquid inlet pipe 1 and the liquid outlet pipe 2 into the corresponding manifold, avoiding the impact of displacement of the manifold on the pressing effect. Furthermore, the pressing cylinder acts on the side walls of the liquid inlet pipe 1 and the liquid outlet pipe 2, which can reduce the deformation at the connection between the liquid inlet pipe 1 and the liquid outlet pipe 2 and the corresponding manifold, thereby improving the pressing effect.

[0035] It is understandable that the first positioning element 51 and the second positioning element 52 can also be a snap-fit, a gripper or other structure, which can work together with the limiting block 53 to limit the position of the evaporator core 3. No further examples will be listed here.

[0036] See Figures 1 to 3In some embodiments, the pipe positioning assembly 6 includes a first positioning plate 61, a second positioning plate 62, and a positioning drive 63. The first positioning plate 61 has a first positioning groove 611 for locking the inlet pipe 1 and the outlet pipe 2, and the second positioning plate 62 has a second positioning groove 621 for locking the inlet pipe 1 and the outlet pipe 2. The positioning drive 63 is connected to the first positioning plate 61 and the second positioning plate 62 and is used to drive the first positioning plate 61 and the second positioning plate 62 to move in a direction close to or away from the evaporator core 3.

[0037] In this embodiment, the first positioning plate 61 and the second positioning plate 62 are vertically arranged and move synchronously. The positioning drive component 63 is a positioning cylinder. The output end of the positioning cylinder is connected to a connecting plate 631. The first positioning plate 61 and the second positioning plate 62 are both fixedly connected to the connecting plate 631. The moving direction of the output end of the positioning cylinder is parallel to the length direction of the base 4, so as to push the first positioning plate 61 and the second positioning plate 62 to move closer to the evaporator chip. The first positioning plate 61 is vertically arranged and has two first positioning grooves 611, which are respectively engaged with the liquid inlet pipe 1 and the liquid outlet pipe 2. The two first positioning grooves 611 are spaced apart on the side of the first positioning plate 61 facing the evaporator core 3. The second positioning plate 62 is horizontally arranged and has two second positioning grooves 621, which are respectively engaged with the end of the liquid inlet pipe 1 and the end of the liquid outlet pipe 2. The two second positioning grooves 621 are spaced apart in the horizontal direction.

[0038] Thus, after the inlet pipe 1 and outlet pipe 2 are inserted into the manifold of the evaporator core 3, the positioning cylinder drives the connecting plate 631 to move closer to the evaporator body, so that the first positioning groove 611 opened on the first positioning plate 61 respectively engages with the inlet pipe 1 and outlet pipe 2, and the ends of the inlet pipe 1 and outlet pipe 2 are engaged with the corresponding second positioning groove 621, thereby positioning the inlet pipe 1 and outlet pipe 2. This facilitates the subsequent pressing of the inlet pipe 1 and outlet pipe 2 into the corresponding manifold by the pressing cylinder, and the riveting pin 82 rivets the inlet pipe 1 and outlet pipe 2, completing the assembly of the inlet pipe 1 and outlet pipe 2. The first positioning plate 61 and the second positioning plate 62 can fix the inlet pipe 1 and outlet pipe 2, reducing their displacement and deformation during assembly, and distributing the force on the inlet pipe 1 and outlet pipe 2, avoiding damage to the inlet pipe 1 or outlet pipe 2 due to localized force, and improving the pressing effect.

[0039] It is understandable that the positions of the first positioning plate 61 and the second positioning plate 62 can be adjusted according to actual needs, as long as they can restrict the movement of the inlet pipe 1 and the outlet pipe 2. Further details will not be provided here.

[0040] See Figure 3In some embodiments, the base 4 is connected to two limiting members 41, which are respectively connected to the positioning drive member 63 and the pressing drive member 7.

[0041] Thus, by limiting the movement distance of the positioning drive 63 and the pressing drive 7 by the limiting member 41, excessive movement and interference of the corresponding connected structures can be avoided, thereby improving the structural stability and safety of the evaporator inlet and outlet liquid pipe assembly device.

[0042] It is understandable that the number and position of the limiting components 41 can be adjusted according to actual needs, which will not be elaborated here.

[0043] See Figure 2 In some embodiments, the push-in drive 7 is connected to a sliding seat 71, and the base 4 is provided with a slide rail 42 corresponding to the sliding seat 71 so that the sliding seat 71 can move on the slide rail 42. The positioning drive 63 is provided on the sliding seat 71.

[0044] In this embodiment, the output end of the pressing cylinder is fixedly connected to the sliding seat 71, and the length direction of the slide rail 42 is parallel to the moving direction of the output end of the pressing cylinder, so that the pressing cylinder can drive the positioning cylinder and the first positioning plate 61 and the second positioning plate 62 to move along the width direction of the bottom plate, pressing the positioned inlet pipe 1 and outlet pipe 2 into the corresponding collecting pipe.

[0045] Thus, the positioning cylinder is supported by the sliding seat 71 and moves along the width direction of the base 4 with the sliding seat 71, which can improve the movement stability of the first positioning plate 61 and the second positioning plate 62. The fixed end of the positioning cylinder is fixedly set on the sliding seat 71, and the sliding seat 71 is slidably set on the slide rail 42, which can improve the positioning accuracy of the liquid inlet pipe 1 and the liquid outlet pipe 2, so as to press the liquid inlet pipe 1 and the liquid outlet pipe 2 into the corresponding manifold respectively, thereby improving the pressing effect.

[0046] It is understandable that there may be one or more slide rails 42. The number and position of slide rails 42 can be flexibly adjusted to enable the sliding seat 71 to move smoothly along the width of the base 4. Further details will not be provided here.

[0047] See Figure 3 In some embodiments, the limiting member 41 is a limiting rod, and the bottom of the limiting rod is connected to the limiting seat 411. The limiting rod and the limiting seat 411 are threadedly connected to adjust the relative position of the limiting rod and the base 4.

[0048] In this embodiment, the limiting seat 411 corresponding to one of the limiting rods is fixedly installed on the base 4. The extension direction of the limiting rod is perpendicular to the movement direction of the output end of the positioning cylinder. By rotating the limiting rod, it can be moved in a direction closer to or away from the positioning cylinder, thereby adjusting the extension distance of the output end of the pressing cylinder. The limiting seat 411 corresponding to the other limiting rod is fixedly installed on the sliding seat 71. By rotating the limiting rod, it can be moved in a direction closer to or away from the connecting plate 631, thereby adjusting the extension distance of the output end of the positioning cylinder.

[0049] In this way, the limiting rod can limit the extension distance of the output end of the pressing cylinder and the output end of the positioning cylinder, avoiding collisions between the liquid inlet pipe 1 and the liquid outlet pipe 2 and the evaporator liquid inlet and outlet pipe assembly device due to excessive movement, thus preventing deformation or damage. This improves the stability of the pressing cylinder and the positioning cylinder, allowing the liquid inlet pipe 1 and the liquid outlet pipe 2 to be accurately pressed into the manifold, thereby improving the pressing effect.

[0050] It is understandable that the limiting component 41 can also be a limiting baffle or other structures. The specific structure of the limiting component 41 can be adjusted according to actual needs, and will not be listed in detail here.

[0051] See Figure 2 In some embodiments, the riveting assembly 8 further includes a linkage shaft 83, one end of which is fixedly connected to the riveting drive 81, and the other end is connected to the rivet pin 82.

[0052] In this embodiment, the riveting drive 81 is a riveting cylinder, and the linkage shaft 83 is fixedly connected to the output end of the riveting cylinder.

[0053] Thus, by setting the linkage shaft 83, the core positioning component 5, the pipe positioning component 6, the pressing drive component 7 and the riveting component 8 can be reasonably set, making the structure more compact and facilitating the riveting of the inlet pipe 1 and the outlet pipe 2, so that the inlet pipe 1 and the outlet pipe 2 are respectively firmly connected to the corresponding manifold, thereby improving the pressing effect.

[0054] It should be noted that the linkage shaft 83 can be connected to the rivet pin 82 through a linkage mechanism to extend the rivet pin 82, or it can be directly connected to the rivet pin 82. Driving the rivet pin 82 through a riveting cylinder is existing technology and will not be elaborated here.

[0055] See Figure 2 In some embodiments, four rivet pins 82 are provided, with two rivet pins 82 corresponding to the liquid inlet pipe 1 and the other two rivet pins 82 corresponding to the liquid outlet pipe 2.

[0056] In this embodiment, two rivet pins 82 corresponding to the liquid inlet pipe 1 are symmetrically arranged on the side wall of the liquid inlet pipe 1, and two rivet pins 82 corresponding to the liquid outlet pipe 2 are symmetrically arranged on the side wall of the liquid outlet pipe 2, so as to realize the riveting of the liquid inlet pipe 1 or the liquid outlet pipe 2.

[0057] Thus, by setting two rivet points for both the inlet pipe 1 and the outlet pipe 2, the inlet pipe 1 and the outlet pipe 2 can be securely connected to the corresponding manifold, avoiding the inlet pipe 1 or the outlet pipe 2 from falling off from the manifold due to insufficient pressing or misalignment of the rivet points, thereby improving the pressing effect.

[0058] Understandably, the number and position of the rivet pins 82 can be adjusted according to actual needs, which will not be elaborated here.

[0059] See Figure 1 In some embodiments, the base 4 is connected to an identification element 43 for identifying the model of the evaporator core 3.

[0060] In this embodiment, the identification component 43 is an RFID (Radio Frequency Identification) identification device, which can identify the corresponding tag on the evaporator core 3 and determine whether the evaporator core 3 to be assembled is compatible with the evaporator inlet and outlet liquid pipe assembly device.

[0061] This improves assembly accuracy and reduces problems such as difficulty in assembling the inlet pipe 1 and outlet pipe 2 due to mismatch between the evaporator core 3 and the evaporator inlet and outlet pipe assembly device, and damage to the evaporator core 3 caused by the core positioning component 5.

[0062] It is understandable that the identification element 43 can also be a visual identification device, a barcode identification device, etc. The specific type of identification element 43 can be adjusted according to the corresponding marking on the evaporator core 3, and will not be listed in detail here.

[0063] The operating principle of an evaporator inlet and outlet liquid pipe assembly device is as follows:

[0064] Place the evaporator core 3 to be assembled between the first positioning block and the limiting block 53, and start the pushing cylinder 54 to push the upper left corner and the lower left corner of the evaporator core 3 respectively, so that the evaporator core 3 is clamped by the first positioning block, the second positioning block and the limiting block 53, restricting the relative position of the evaporator core 3 and the base 4.

[0065] Insert the inlet pipe 1 and the outlet pipe 2 into the collecting pipe in sequence, and then insert the ends of the inlet pipe 1 and the outlet pipe 2 away from the collecting pipe into the second positioning grooves 621 on the second positioning plate 62. Activate the positioning cylinder to move the connecting plate 631 toward the first positioning plate 61 and lock the inlet pipe 1 and the outlet pipe 2. The pressing cylinder pulls the inlet pipe 1 and the outlet pipe 2 in the width direction of the base 4, so that the inlet pipe 1 and the outlet pipe 2 are pressed into the corresponding collecting pipes for further fixation.

[0066] The riveting cylinder is activated so that the riveting pin 82 rivets the connection between the inlet pipe 1 and the corresponding manifold, and the connection between the outlet pipe 2 and the corresponding manifold, respectively, so that the inlet pipe 1 and the corresponding manifold, and the outlet pipe 2 and the corresponding manifold are fixedly connected, thus completing the assembly of the inlet pipe 1 and the outlet pipe 2.

[0067] The press-in cylinder, positioning cylinder, and push cylinder 54 are reset, which allows the evaporator core 3, which is equipped with liquid inlet pipe 1 and liquid outlet pipe 2, to be removed from the evaporator liquid inlet and outlet pipe assembly device.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
