A supporting bottom plate is fixedly installed in the middle of the inner side of the U-shaped plate. Spiral groove rollers are rotatably arranged on both the left and right sides of the upper part of the supporting bottom plate. A buffering mechanism for buffering the fins is arranged on the U-shaped plate, and a sorting mechanism for centering and aligning the fins is also arranged on the U-shaped plate. In the present invention, the left abutting rod can buffer the fins under the push of the elastic force of the buffer spring, so that the fins can slowly stop between two adjacent flat tubes, preventing the fins from hitting the spiral groove rollers.

Description

Technical Field

[0001] The present invention relates to the field of automotive parts production and manufacturing, and specifically to an automotive condenser production and assembly device. Background Art

[0002] The automotive condenser is a part of the refrigeration system, mainly composed of flat tubes and fins, etc. The flat tubes and fins are arranged overlapping one by one. The flat tubes are used to guide the refrigerant, and the fins are used to conduct the high temperature on the flat tubes to the air, so as to dissipate heat and refrigerate. When assembling the fins, it is necessary to ensure their flatness, without obvious wrinkles, breakages or deformations, so as to ensure the contact area between the fins and the air, and further ensure the heat exchange efficiency.

[0003] Currently, a spiral roller is mainly used to separately convey the flat tubes one by one, and then a conveyor belt is used to convey the fins between two adjacent flat tubes. During this process, the fins will collide with the spiral roller under the action of inertia, causing the fins to bend or even pop out outside two adjacent flat tubes, and then manual adjustment is required, reducing the assembly efficiency.

[0004] In addition, due to the continuously bent structure of the fins, the fins have a certain degree of flexibility, making it difficult for the conveyor belt to transport the fins to the middle position between two adjacent flat tubes. And due to the friction between the fins and the flat tubes and the friction of the conveyor belt on the fins, when the fins are between two adjacent flat tubes, it is impossible to ensure that each bending angle is the same, and then the fins show uneven density distribution, affecting the assembly quality of the condenser.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention uses the left-side abutment rod to buffer the fins moving from right to left between two adjacent flat tubes under the push of the buffer spring elastic force, so that the fins can slowly stop between the two adjacent flat tubes to prevent the fins from colliding with the spiral groove roller, and when the fins move, the rectangular frame drives the conveying assembly located at the lower part of the supporting bottom plate, so that when the conveying assembly drives the fins to move between the flat tubes, the upper side of the fins is lower than the upper side of the flat tubes, thereby preventing the fins from popping out to the outside of the flat tubes, thereby avoiding manual arrangement of the fins and ensuring assembly efficiency.

[0018] 2. The present invention adopts a moving component that can drive the two abutment rods to move downward to the left and right sides of the fin, and can push the fin to the center position of the flat tube by synchronously moving the two abutment rods close to each other, and then drive the fin to move downward through the alignment component, so that the combing block adjusts each bending angle of the fin through the inclined groove thereon, so that each bending angle of the fin is the same, and then the alignment component clamps the fin and moves the fin upward to be flush with the flat tube, thereby completing the adjustment of the fin and ensuring the assembly quality of the condenser.

[0019] 3. The present invention uses spiral groove rollers with unequal pitches to move and convey the flat tubes, so that when the fins move between two adjacent flat tubes, the distance between the two adjacent flat tubes is larger, so that the fins can move smoothly between the two flat tubes. After the position of the fins is adjusted, the spiral groove rollers can shorten the distance between the two adjacent flat tubes while moving the flat tubes, so that the flat tubes clamp the fins front and back, thereby preventing the fins from changing position during the subsequent movement process.

Detailed Description of the Invention

[0032] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention. For those not specified in the embodiments regarding specific techniques or conditions, they shall be carried out according to the techniques or conditions described in the literature in this field or according to the product specifications.

[0033] Refer to Figure 1 and Figure 10, An automobile condenser production and assembly device, including a U-shaped plate 1. In the middle of the inner side of the U-shaped plate 1, a supporting bottom plate 2 is fixedly installed. On the upper part of the supporting bottom plate 2, spiral groove rollers 3 are rotatably arranged on both the left and right sides. On the U-shaped plate 1, a buffer mechanism 4 for buffering the fins is provided, and on the U-shaped plate 1, an arrangement mechanism 5 for centering and aligning the fins is also provided.

[0034] Refer to Figure 1 and Figure 2 , The arrangement mechanism 5 includes a rectangular frame 51 that slides up and down between the two vertical sections of the U-shaped plate 1. A through slot that penetrates up and down is opened on the front side of the supporting bottom plate 2, and the rear side of the through slot is flush with the rear side of the rectangular frame 51. An inlet 11 for the fins to enter is opened on the right vertical section of the U-shaped plate 1. The pitch of the spiral groove on the spiral groove roller 3 corresponding to the part of the U-shaped plate 1 and the part located in front of the U-shaped plate 1 is greater than the pitch of the part located behind the U-shaped plate 1.

[0035] When it is necessary to stack the flat tubes and fins one by one, the flat tubes are placed one by one between the spiral grooves of the two spiral groove rollers 3 through an existing tube placing mechanism, and the lower side of the flat tubes is supported by the supporting bottom plate 2. Subsequently, the spiral groove on the spiral groove roller 3 pushes the flat tubes to move backward. At the same time, the fins are slid from right to left into the interior of the U-shaped plate 1 through the inlet 11 by an existing guide vane mechanism, so that the fins move between two adjacent flat tubes. During this process, the movement of the fins is buffered by the buffer mechanism 4, so that the fins stop slowly, preventing the fins from bouncing. Subsequently, the arrangement mechanism 5 moves the fins to the central position between two adjacent flat tubes, and at the same time arranges each bending angle of the fins. Then, the spiral groove roller 3 drives the fins to continue moving backward by pushing the flat tubes.

[0036] It should be noted that both the guide vane mechanism and the tube placing mechanism are completed by existing automated devices, and will not be elaborated in this embodiment.

[0037] Refer to Figure 1 , Figure 3 and Figure 4 , The buffer mechanism 4 includes a lifting plate 41 that slides up and down between the two vertical sections of the U-shaped plate 1. The lifting plate 41 is located above the supporting bottom plate 2. Two symmetrically arranged sliding members 42 slide left and right on the lifting plate 41. A buffer spring is arranged between the left sliding member 42 and the lifting plate 41. An abutting rod 43 slides up and down inside the sliding member 42. The buffer mechanism 4 also includes a moving component 44 for driving the abutting rod 43 to move horizontally and vertically.

[0038] Refer to Figure 1 , Figure 3 , Figure 4 and Figure 5, the moving component 44 includes a moving plate 441 that is vertically slidably arranged between the two vertical sections of the U-shaped plate 1. The moving plate 441 is located above the lifting plate 41. Two through slots 442 arranged left and right are formed on the moving plate 441. A right trapezoidal block 443 is slidably inserted into the upper part of the abutting rod 43 in the front and rear directions. A return spring is arranged between the right trapezoidal block 443 and the abutting rod 43. The through slot 442 has an L-shaped structure, and the longitudinal section of the L-shaped structure of the through slot 442 is located on the right side of its transverse section. The hypotenuse of the right trapezoidal block 443 faces the upper front side.

[0039] In the initial state, the left abutting rod 43 is located below the moving plate 441, and the right trapezoidal block 443 on the right abutting rod 43 is located above the moving plate 441, so that the upper end of the right abutting rod 43 passes through the right through slot 442, and the lower end of the right abutting rod 43 is located above the flat tube on the spiral groove roller 3, thereby preventing the right abutting rod 43 from blocking the fin from moving between two adjacent flat tubes on the spiral groove roller 3. At this time, the spiral groove roller 3 drives two adjacent flat tubes to be located on the front and rear sides of the abutting rod 43.

[0040] Refer to Figure 1 、 Figure 3 and Figure 6 , the sorting mechanism 5 further includes a conveying component 52 arranged on the rectangular frame 51. The conveying component 52 includes belt rollers 521 that are symmetrically and rotatably arranged on the rectangular frame 51 from left to right. The two belt rollers 521 are located between the two spiral groove rollers 3. Two conveyor belts 522 arranged symmetrically from front to back are jointly wound on the two belt rollers 521. An actuating motor 523 connected to one of the belt rollers 521 is fixedly installed on the front side of the rectangular frame 51.

[0041] In the initial state, the rectangular frame 51 drives the conveyor belt 522 to be located below the support bottom plate 2. When the fin slides into the inside of the U-shaped plate 1 through the feed port 11, the part of the fin located inside the U-shaped plate 1 falls onto the two conveyor belts 522 under the action of gravity. Then, the actuating motor 523 is started to drive the belt roller 521 connected thereto to rotate. The belt roller 521 drives the two conveyor belts 522 to rotate synchronously, so that the conveyor belts 522 pull the fin from right to left.

[0042] When the left end of the fin moving quickly to the left abuts against the left abutting rod 43, the fin pushes the left abutting rod 43 to move left synchronously through its own inertia and the friction force between it and the conveyor belt 522. The left abutting rod 43 compresses the buffer spring through the left sliding member 42, so that the buffer spring gradually pushes the fin back through its own elastic force, making the fin slow down slowly, thereby buffering the fin. When the fin completely moves onto the conveyor belt 522, the actuating motor 523 is stopped, so that the conveyor belt 522 stops driving the fin.

[0043] Since the conveyor belt 522 is located below the support plate 2, the upper side of the fins moving on the conveyor belt 522 is also located below the upper sides of the flat tubes on its front and rear sides. Thus, the fins are protected and blocked by two adjacent flat tubes on the front and rear sides of the fins, preventing the fins from bouncing outside the flat tubes.

[0044] Refer to Figure 3 and Figure 4 The moving assembly 44 further includes a first electric push rod 446 and a second electric push rod 447. A linkage plate 444 is slidably arranged back and forth through a guide post in the middle of the rear side of the lifting plate 41. Push-pull plates 445 are hinged to both the left and right sides of the linkage plate 444. One end of the push-pull plate 445 away from the linkage plate 444 is hinged to the sliding member 42 at the corresponding position. The second electric push rod 447 is fixedly installed on the right side of the lifting plate 41.

[0045] When the left sliding member 42 moves to the left, the left sliding member 42 pulls the linkage plate 444 forward through the left push-pull plate 445. The linkage plate 444 then pushes the right sliding member 42 to move to the right through the right push-pull plate 445, so that the two sliding members 42 drive the two abutting rods 43 to move synchronously in opposite directions.

[0046] When the conveyor belt 522 stops driving the fins, the left side of the fin abuts against the left abutting rod 43. At the same time, the conveyor belt 522 drives the right end of the fin to move to the left part of the right abutting rod 43, and the fin drives the right abutting rod 43 to move to the longitudinal section position of the right through slot 442 by pushing the left abutting rod 43, so that the moving plate 441 no longer blocks the right-angled trapezoidal block 443 on the right abutting rod 43. Thus, the right abutting rod 43 moves downward under the action of gravity, and then the fin is located between the two abutting rods 43.

[0047] Subsequently, extend the telescopic section of the second electric push rod 447, so that the telescopic section of the second electric push rod 447 pushes the right sliding member 42 to the left, thereby enabling the two abutting rods 43 to move closer to each other synchronously. Further, the two abutting rods 43 clamp and push the fin from left and right, pushing the fin to the middle position of the flat tube, and at this time, the abutting rods 43 respectively correspond to the transverse section positions of the through slots 442 at the corresponding positions.

[0048] Refer to Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 The sorting mechanism 5 further includes an L-shaped rod 53 fixedly installed on the left side of the right vertical section of the U-shaped plate 1. A sorting block 54 is fixedly installed on the upper part of the vertical section of the L-shaped rod 53. Inclined slots 55 for inserting the fins are equally spaced in the left-right direction on the sorting block 54. Two adjacent inclined slots 55 are symmetrically arranged. The sorting mechanism 5 further includes an alignment assembly 56 for clamping the fins up and down.

[0049] Refer to Figure 1 、 Figure 3 and Figure 9 As shown in FIGS.

[0050] Refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 10 Inside the rectangular frame 51, a support plate 511 is fixedly installed on the upper side. A notch for the insertion of the combing block 54 is formed in the middle of the support plate 511. The upper side surface of the support plate 511 is attached to the lower side surface of the upper horizontal section of the conveyor belt 522.

[0051] After the two abutting rods 43 clamp and push the fins, the telescopic section of the third electric push rod 565 is retracted, so that the third electric push rod 565 drives the rectangular frame 51 to move downward. The rectangular frame 51 drives the fins to move downward synchronously through the conveyor belt 522, so that the combing block 54 moves upward relative to the rectangular frame 51. Thus, the combing block 54 aligns and shapes the continuously bent fins through the inclined slots 55 thereon.

[0052] In this embodiment, chamfers are provided at the upper side edges of the inclined slots 55 of the combing block 54, so that each bent section of the fins can be inserted into the inclined slots 55 more smoothly. Thus, through the pushing and limiting of each bent section of the fins by the inclined slots 55, each bending angle of the fins is the same, thereby ensuring the assembly quality.

[0053] Subsequently, the telescopic section of the third electric push rod 565 is extended to drive the fins to move upward, so that the upper side surface of the fins is flush with the upper side surface of the flat tube. While the rectangular frame 51 moves, it drives the rotating plate 563 to rotate through the lower hinge plate 564. The rotating plate 563 simultaneously drives the lifting plate 41 to move in the opposite direction through the upper hinge plate 564, so that the rectangular frame 51 and the lifting plate 41 move in the same direction and in opposite directions.

[0054] When the upper side surface of the fins driven by the rectangular frame 51 is flush with the upper side surface of the flat tube, the lifting plate 41 drives the pushing roller 562 to abut against the upper side surface of the fins through the roller frame 561, so that the pushing roller 562 and the conveyor belt 522 clamp the fins in the up and down directions. Thus, the upper side surface of the fins is flattened by the pushing of the pushing roller 562, and at the same time, the lower side surface of the fins is flattened by the support plate 511 supporting the conveyor belt 522, increasing the flatness of the fins and improving the assembly quality.

[0055] Refer to Figure 1 、 Figure 2 and Figure 3 On the horizontal section of the U-shaped plate 1, a first electric push rod 446 is fixedly installed. The telescopic section of the first electric push rod 446 is fixedly connected to the moving plate 441. A belt is wound around the front parts of the two spiral groove rollers 3 together. A power motor 21 is fixedly installed on the front side of the supporting bottom plate 2. The output shaft of the power motor 21 is fixedly connected to one of the spiral groove rollers 3.

[0056] When the upper side of the fin driven by the rectangular frame 51 is flush with the upper side of the flat tube, the telescopic section of the extended first electric push rod 446 drives the moving plate 441 to move downward to the position of the abutting rod 43, so that the upper end of the abutting rod 43 passes through the through groove 442 at the corresponding position. The edge of the through groove 442 contacts the inclined surface of the right-angled trapezoidal block 443 and pushes the right-angled trapezoidal block 443 backward, so that the right-angled trapezoidal block 443 completely contracts into the inside of the abutting rod 43. Subsequently, the moving plate 441 moves downward to the lower side of the right-angled trapezoidal block 443, and then the right-angled trapezoidal block 443 moves forward and resets under the push of the elastic force of the return spring.

[0057] After that, the telescopic section of the retracted first electric push rod 446 drives the moving plate 441 to move upward, so that the first electric push rod 446 drives the two abutting rods 43 to move upward synchronously by pushing the right-angled trapezoidal block 443. During the upward movement of the abutting rod 43, the power motor 21 is started to drive the two spiral groove rollers 3 to rotate synchronously, so that the spiral groove rollers 3 quickly push the flat tube in front of the fin backward and slowly push the flat tube behind the fin backward, so that the flat tube in front of the fin pushes the fin to abut against the flat tube behind, so as to clamp and limit the fin through the two flat tubes and prevent the fin from displacing during the movement.

[0058] Then the spiral groove rollers 3 drive the fin and the flat tubes on its front and rear sides to move backward synchronously to the working position of the next process of assembling the flat tube and the fin.

[0059] At the same time, the moving plate 441 drives the two abutting rods 43 to completely move to the upper side of the flat tube, so as to prevent the abutting rods 43 from hindering the movement of the flat tube. At this time, the left abutting rod 43 is no longer blocked by the fin, so that the buffer spring pushes the left abutting rod 43 to move rightward to the longitudinal section position of the left through groove 442 through its own elastic force. At the same time, the right abutting rod 43 moves leftward to the left end of the transverse section of the right through groove 442, so that the right-angled trapezoidal block 443 on the left abutting rod 43 is no longer blocked by the moving plate 441, and then the left abutting rod 43 moves downward to the initial position under the action of gravity.

[0060] Then, retract the telescopic section of the third electric push rod 565 to drive the conveyor belt 522 to move downward to the initial position, and retract the telescopic section of the second electric push rod 447 to the initial position.

[0061] Refer to Figures 1 - 10 , when the present invention stacks the flat tubes and fins one by one, the following steps are included: First step, the fin slides into the interior of the U-shaped plate 1 through the feed port 11. Start the actuator motor 523 to pull the fin from right to left through the conveyor belt 522, so that the left end of the fin abuts against the left-side abutting rod 43, and the buffer spring gradually pushes the fin backward.

[0062] Second step, the conveyor belt 522 stops driving the fin, so that the right end of the fin moves to the left of the right-side abutting rod 43, and the fin drives the right-side abutting rod 43 to move to the longitudinal section position of the right-side through slot 442, so that the right-side abutting rod 43 moves downward under the action of gravity, and further the fin is located between the two abutting rods 43.

[0063] Third step, extend the telescopic section of the second electric push rod 447 to clamp and push the two abutting rods 43 and the fin left and right, and push the fin to the middle position of the flat tube. At this time, the abutting rods 43 correspond to the transverse section positions of the through slots 442 at the corresponding positions.

[0064] Fourth step, retract the telescopic section of the third electric push rod 565, so that the third electric push rod 565 drives the rectangular frame 51 to move downward, and the rectangular frame 51 drives the fin to move downward synchronously through the conveyor belt 522, so that the combing block 54 moves upward relative to the rectangular frame 51, so that the combing block 54 aligns and shapes the continuously bent fin through the inclined slot 55 thereon.

[0065] Fifth step, extend the telescopic section of the third electric push rod 565, so that the pushing roller 562 and the conveyor belt 522 clamp the fin in the up and down directions, so as to flatten the upper side of the fin by the pushing of the pushing roller 562. At the same time, the conveyor belt 522 is supported by the support plate 511 to flatten the lower side of the fin, increasing the flatness of the fin and improving the assembly quality.

[0066] Sixth step, extend the telescopic section of the first electric push rod 446 to drive the moving plate 441 to move downward to the lower side of the right-angled trapezoidal block 443, and then retract the telescopic section of the first electric push rod 446 to drive the two abutting rods 43 to move upward synchronously. At the same time, start the power motor 21 to drive the two flat tubes to clamp and limit the fin through the spiral groove roller 3, preventing the fin from displacing during the movement.

[0067] In the seventh step, the moving plate 441 drives the two abutting rods 43 to completely move to the upper side of the flat tube, thereby preventing the abutting rods 43 from hindering the movement of the flat tube. The buffer spring pushes the left abutting rod 43 to move rightward to the longitudinal section position of the left through slot 442 by its own elastic force, so that the left abutting rod 43 moves downward to the initial position under the action of gravity.

[0068] In the eighth step, the contraction of the telescopic section of the third electric push rod 565 drives the conveyor belt 522 to move downward to the initial position, and the telescopic section of the second electric push rod 447 is contracted to the initial position.

[0069] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
