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] An 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, damage or deformation, so as to ensure the contact area between the fins and the air, and further ensure the heat exchange efficiency.

[0003] At present, 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 appear unevenly distributed, affecting the assembly quality of the condenser. Summary of the Invention

Push-pull plates are hinged to both the left and right sides of the linkage plate. One end of the push-pull plate away from the linkage plate is hinged to the sliding part at the corresponding position.

[0011] Preferably, the moving component further includes a first electric push rod and a second electric push rod. The first electric push rod is fixedly installed on the horizontal section of the U-shaped plate. The telescopic section of the first electric push rod is fixedly connected to the moving plate. The second electric push rod is fixedly installed on the right side of the lifting plate.

[0012] Preferably, the conveying component includes belt rollers symmetrically arranged left and right and rotatably arranged on the rectangular frame. The two belt rollers are located between two spiral groove rollers. Two conveyor belts arranged front and rear symmetrically are jointly wound around the two belt rollers. An execution motor connected to one of the belt rollers is fixedly installed on the front side of the rectangular frame.

[0013] Preferably, a support plate is fixedly installed on the upper side inside the rectangular frame. A notch for inserting the combing block is formed in the middle of the support plate. The upper side surface of the support plate is attached to the lower side surface of the upper horizontal section of the conveyor belt.

[0014] Preferably, the alignment component includes a roller frame fixedly installed on the lifting plate. A pushing roller is rotatably arranged at the lower part of the roller frame. A rotating plate is rotatably arranged on the left side of the left vertical section of the U-shaped plate. Two ends of the rotating plate are respectively hinged to the lifting plate and the rectangular frame through hinge plates. A third electric push rod is jointly installed between the lower left part of the rectangular frame and the U-shaped plate.

[0015] Preferably, a belt is jointly wound around the front parts of the two spiral groove rollers. A power motor is fixedly installed on the front side of the bottom support plate. The output shaft of the power motor is fixedly connected to one of the spiral groove rollers.

[0016] Preferably, a clearance groove running through the upper and lower parts is provided on the front side of the bottom support plate, the rear side surface of the clearance groove is flush with the rear side surface of the rectangular frame, a feed port for the fins to enter is provided on the right vertical section of the ribbed plate, and the pitch of the spiral groove on the spiral groove roller corresponding to the part of the ribbed plate and located on the front side of the ribbed plate is greater than the pitch located on the rear side of the ribbed plate.

[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 implementation manners

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

[0033] Refer to Figure 1 and Fig.10, a production and assembly equipment for automobile condensers, including a convex plate 1, a bottom support plate 2 is fixedly installed in the middle of the inner side of the convex plate 1, spiral groove rollers 3 are rotatably arranged on the left and right sides of the upper part of the bottom support plate 2, a buffer mechanism 4 for buffering fins is arranged on the convex plate 1, and a finishing mechanism 5 for centering the fins is also arranged on the convex plate 1.

[0034] See also Figure 1 and Figure 2 The finishing mechanism 5 includes a rectangular frame 51 which is slidably arranged between two vertical sections of the shaped plate 1. A vertically penetrating make-way groove is provided on the front side of the bottom support plate 2. The rear side of the make-way groove is flush with the rear side of the rectangular frame 51. A feed port 11 for the fins to enter is provided on the right vertical section of the shaped plate 1. The spiral groove on the spiral groove roller 3 corresponds to the part of the shaped plate 1 and the pitch of the part located on the front side of the shaped plate 1 is greater than the pitch of the part located on the rear side of the 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 the existing tube placing mechanism, and the lower side of the flat tube is supported by the bottom plate 2, and then the spiral groove on the spiral groove roller 3 pushes the flat tube to move backward, and at the same time, the fin is slid from right to left through the feed port 11 to the inside of the convex plate 1 through the existing guide mechanism, so that the fin moves between two adjacent flat tubes. In this process, the movement of the fin is buffered by the buffer mechanism 4, so that the fin stops slowly to prevent the fin from bouncing, and then the arranging mechanism 5 moves the fin to the center position between the two adjacent flat tubes, and at the same time arranges each bending angle of the fin, and then the spiral groove roller 3 drives the fin to continue to move backward by pushing the flat tube.

[0036] It should be noted that both the blade guide mechanism and the tube release mechanism are completed by existing automated devices, which will not be described in detail in this embodiment.

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

[0038] See also Figure 1 , Figure 3 , Figure 4 and Figure 5, the moving component 44 includes a moving plate 441 that is slidably arranged up and down 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-angled 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-angled 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-angled 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-angled 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 left and right on the rectangular frame 51. The two belt rollers 521 are located between the two spiral groove rollers 3. Two conveyor belts 522 arranged symmetrically front and rear are jointly wound around 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 interior 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 belt 522 pulls 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 decelerate 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 at the lower part of the supporting base plate 2, the upper side surface of the fin moving on the conveyor belt 522 is also located at the lower side of the upper side surface of the flat tubes on its front and rear sides, so that the fin is protected and blocked by the two adjacent flat tubes on the front and rear sides of the fin to prevent the fin from bouncing to the outside of the flat tube.

[0044] See also Figure 3 and Figure 4 The moving assembly 44 also includes a No. 1 electric push rod 446 and a No. 2 electric push rod 447. A linkage plate 444 is provided in the middle of the rear side of the lifting plate 41 for sliding back and forth through a guide column. Push-pull plates 445 are hinged on 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. A No. 2 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, and the linkage plate 444 pushes the right sliding member 42 to the right through the right push-pull plate 445, so that the two sliding members 42 drive the two abutment rods 43 to move in opposite directions synchronously.

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

[0047] Then, the telescopic section of the No. 2 electric push rod 447 is extended, so that the telescopic section of the No. 2 electric push rod 447 pushes the sliding member 42 on the right side to the left, so that the two abutment rods 43 are synchronously close to each other, and then the two abutment rods 43 clamp and push the fins to the left and right, pushing the fins to the middle position of the flat tube, and at this time, the abutment rods 43 all correspond to the lateral section position of the through slot 442 at the corresponding position.

[0048] See also Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The arranging mechanism 5 also includes an L-shaped rod 53 fixedly mounted on the left side of the right vertical section of the shaped plate 1, a combing block 54 is fixedly mounted on the upper part of the vertical section of the L-shaped rod 53, and inclined grooves 55 for inserting fins are provided on the combing block 54 at equal intervals along the left and right directions, and two adjacent inclined grooves 55 are symmetrically arranged. The arranging mechanism 5 also includes an alignment component 56 for clamping the fins up and down.

[0049] See also Figure 1 , Figure 3 and Fig. 9 The alignment component 56 includes a roller frame 561 fixedly installed on the lifting plate 41, a pushing roller 562 is rotatably provided at the lower part of the roller frame 561, a rotating plate 563 is rotatably provided on the left side of the left vertical section of the shaped plate 1, and both ends of the rotating plate 563 are respectively hinged to the lifting plate 41 and the rectangular frame 51 through hinge plates 564, and a No. 3 electric push rod 565 is jointly installed between the lower left side of the rectangular frame 51 and the shaped plate 1.

[0050] See also Figure 6 , Figure 7 , Figure 8 and Fig.10 A support plate 511 is fixedly installed on the upper inner side of the rectangular frame 51 , a slot for the combing block 54 to pass through is opened in the middle of the support plate 511 , and the upper side of the support plate 511 is attached to the lower side of the upper horizontal section of the conveyor belt 522 .

[0051] After the two abutment rods 43 clamp and push the fins, the telescopic section of the No. 3 electric push rod 565 is retracted, so that the No. 3 electric push rod 565 drives the rectangular frame 51 to move downward, and 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, so that the combing block 54 can align and shape the continuously bent fins through the inclined grooves 55 thereon.

[0052] In this embodiment, a chamfer is provided at the upper edge of the inclined groove 55 of the combing block 54, so that each bending section of the fin can be inserted into the inclined groove 55 more smoothly, and each bending section of the fin is pushed and limited by the inclined groove 55, so that each bending angle of the fin is the same, thereby ensuring the assembly quality.

[0053] Then, the telescopic section of the No. 3 electric push rod 565 is extended to drive the fin to move upward, so that the upper side of the fin is flush with the upper side of the flat tube. While the rectangular frame 51 moves, the rotating plate 563 is driven 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 opposite direction synchronously.

[0054] When the rectangular frame 51 drives the upper side of the fin to be flush with the upper side of the flat tube, the lifting plate 41 drives the pushing roller 562 to press against the upper side of the fin through the roller frame 561, so that the pushing roller 562 and the conveyor belt 522 clamp the fin in the up and down directions, thereby smoothing the upper side of the fin through the push of the pushing roller 562, and at the same time smoothing the lower side of the fin by supporting the conveyor belt 522 through the support plate 511, thereby increasing the flatness of the fin 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 trapezoidal block 443 and pushes the right trapezoidal block 443 backward, so that the right trapezoidal block 443 is completely contracted into the inside of the abutting rod 43. Subsequently, the moving plate 441 moves downward to the lower side of the right trapezoidal block 443, and then the right 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 contracted 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 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 roller 3 drives 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 rod 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 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, the telescopic section of the third electric push rod 565 is retracted to drive the conveyor belt 522 to move downward to the initial position, and the telescopic section of the second electric push rod 447 is retracted to the initial position.

[0061] See also Figure 1-Figure 10 The present invention includes the following steps when stacking the flat tubes and fins one by one: In the first step, the fins slide to the inside of the convex plate 1 through the feed port 11, and the execution motor 523 is started to pull the fins from right to left through the conveyor belt 522, so that the left end of the fins abuts against the abutting rod 43 on the left, and the buffer spring gradually pushes the fins back.

[0062] In the second step, the conveyor belt 522 stops driving the fin, so that the right end of the fin moves to the left part of the right abutment rod 43, and the fin drives the right abutment rod 43 to move to the longitudinal section position of the right through groove 442, so that the right abutment rod 43 moves downward under the action of gravity, and then the fin is located between the two abutment rods 43.

[0063] The third step is to extend the telescopic section of the second electric push rod 447 so that the two abutment rods 43 clamp and push the fins to the left and right, pushing the fins to the middle position of the flat tube. At this time, the abutment rods 43 all correspond to the lateral section positions of the through slots 442 at the corresponding positions.

[0064] The fourth step is to retract the telescopic section of the No. 3 electric push rod 565, so that the No. 3 electric push rod 565 drives the rectangular frame 51 to move downward, and 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, so that the combing block 54 can align and shape the continuously bent fins through the inclined grooves 55 thereon.

[0065] The fifth step is to extend the telescopic section of the No. 3 electric push rod 565 so that the pushing roller 562 and the conveyor belt 522 clamp the fin in the up and down directions, thereby smoothing the upper side of the fin through the push of the pushing roller 562, and at the same time smoothing the lower side of the fin by supporting the conveyor belt 522 through the support plate 511, thereby increasing the flatness of the fin and improving the assembly quality.

[0066] The sixth step is to extend the telescopic section of the No. 1 electric push rod 446 to drive the movable plate 441 to move downward to the lower side of the right-angle trapezoidal block 443, and then retract the telescopic section of the No. 1 electric push rod 446 to drive the two abutment rods 43 to move upward synchronously, and at the same time start the power motor 21 to drive the two flat tubes to clamp and limit the fins through the spiral groove roller 3 to prevent the fins from shifting during the movement.

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