Description

Technical Field

[0001] The present invention relates to the technical field of radiator core assembly, and particularly to an assembly tooling for a radiator assembly machine. Background Art

[0002] A radiator core assembly machine is a device used to assemble components such as radiator tubes, radiator fins, and side plates into a complete radiator core according to design requirements. When assembling a radiator core with the related technology, it is necessary for workers to manually align and insert each individual flat radiator tube into a positioning grid one by one, resulting in a very cumbersome process of inserting the flat radiator tubes, excessive time consumption, low assembly efficiency, and high labor intensity for workers.

[0003] Chinese Patent with Publication No. CN113319555B discloses a radiator core assembly device that facilitates the placement of thin plates, including: an assembly platform fixedly connected to a frame, and a clamping cylinder is provided on the assembly platform; a plurality of positioning pin groups slidably connected to the assembly platform, and each positioning pin group is composed of a plurality of positioning pins arranged in a straight line; a feeding assembly horizontally slidably connected to the frame, the feeding assembly is located above the assembly platform, the feeding assembly can output a radiator tube or a radiator fin individually, and the feeding assembly can move at a fixed distance.

[0004] When placing the radiator tubes in the above patent, a plurality of radiator tubes are vertically placed into the accommodating space, the adjusting plate gently abuts the radiator tubes against the limiting plate, the picking plate extends out, presses down the limiting plate, and the flat vacuum suction cup picks up the nearest radiator tube. The picking plate contracts. When the picking plate passes through the feeding port, the vacuum suction cup releases the radiator tube, and the radiator tube falls into the gap in the positioning pin group under the action of gravity. The placement platform moves to the next position under the action of a servo motor to perform cyclic placement of the radiator tubes.

[0005] Although the above patent realizes the automatic feeding of radiator tubes, the entire feeding process involves multiple steps, including vertically placing the radiator tubes, the adjusting plate abutting, the picking plate extending out to pick up, pressing down the limiting plate, the vacuum suction cup picking up, the picking plate contracting, the vacuum suction cup releasing the radiator tube, etc. The series operation of these steps may cause the entire placement process to take a long time, affecting the assembly efficiency, and the entire process involves multiple mechanical components and complex motion control, increasing the complexity and manufacturing cost of the equipment; in addition, when the vacuum suction cup picks up and releases the radiator tubes, it may be affected by factors such as the surface flatness and cleanliness of the radiator tubes, resulting in picking failure or unstable placement, thus affecting the continuous operation of the assembly process.

[0006] Therefore, there is a need in the art for an assembly tooling for a radiator assembly machine to solve the above problems. Summary of the Invention

The stop plate is connected with a third driving member for driving it to open or block the placing opening. When the first driving member drives the placing frame to move until the placing opening is aligned with the positioning grid, the third driving member drives the stop plate to open the placing opening, and the heat dissipation tube drops from the placing opening to the positioning grid. Then, the third driving member drives the stop plate to block the placing opening, and the second driving member drives the pushing plate to push the heat dissipation tube in the placing frame to move above the placing opening.

[0009] When the placing frame of the present invention moves until the placing opening is aligned with the positioning grid, the third driving member drives the stop plate to open the placing opening, and the heat dissipation tube drops from the placing opening to the positioning grid. Then, the third driving member drives the stop plate to block the placing opening, and the second driving member drives the pushing plate to push the heat dissipation tube in the placing frame to move above the placing opening.

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] As Figures 1 to 10As shown in the figure, an assembling tooling for a radiator assembly unit of the present invention includes a frame 1, a positioning assembly, a feeding assembly, and a pressing assembly provided on the frame 1. The extending direction of the heat dissipation tubes 9 of the radiator core during assembly on the frame 1 is defined as the front-back direction. An assembly platform 11 is formed on the frame 1, and two positioning plates 2 are symmetrically arranged on the front and back sides of the assembly platform 11. The positioning assembly includes a plurality of positioning pins 21 provided on the positioning plates 2, and a positioning grid 22 for placing the heat dissipation tubes 9 is formed between two adjacent positioning pins 21 on the left and right. The top of the positioning pin 21 is of a triangular structure, which is beneficial for the heat dissipation tubes 9 fed by the feeding assembly to smoothly enter the positioning grid 22.

[0037] As Figure 1 , Figure 3 and Figure 4 shown in the figure, the feeding assembly includes a feeding frame 3 slidably arranged on the frame 1 in the left-right direction and a pushing plate 31 arranged in the feeding frame 3. A feeding port 32 is formed at the bottom of the feeding frame 3, and a stop plate 33 is arranged at the feeding port 32. A driving member one (not shown in the figure) for driving the feeding frame 3 to move in the left-right direction is arranged on the frame 1. As an example, the driving member one is an electric push rod, the electric push rod is installed on the frame 1, and the feeding frame 3 is fixedly connected to the driving end of the electric push rod.

[0038] The pushing plate 31 is connected with a driving member two for driving it to push the heat dissipation tube 9 to move towards the feeding port 32, and the stop plate 33 is connected with a driving member three for driving it to open or block the feeding port 32. When the driving member one drives the feeding frame 3 to move until the feeding port 32 is aligned with the positioning grid 22, the driving member three drives the stop plate 33 to open the feeding port 32, and the heat dissipation tube 9 drops from the feeding port 32 into the positioning grid 22. Then, the driving member three drives the stop plate 33 to block the feeding port 32, and the driving member two drives the pushing plate 31 to push the heat dissipation tube 9 in the feeding frame 3 to move above the feeding port 32. When the feeding port 32 is opened next time, the heat dissipation tube 9 that has moved above the feeding port 32 automatically drops, realizing the cyclic automatic feeding of the heat dissipation tubes 9.

[0039] As Figure 4 shown in the figure, the positioning plate 2 is slidably matched with the frame 1 in the vertical direction, and a driving member four 12 for driving the positioning plate 2 to move in the vertical direction is arranged on the frame 1. As an example, the driving member four 12 is an electric push rod, the electric push rod extends vertically and is installed on the frame 1, and the positioning plate 2 is fixedly connected to the driving end of the corresponding electric push rod. The driving member four 12 drives the positioning plate 2 to move upward until the positioning pins 21 are located on the front and back sides of the assembly platform 11, or drives the positioning plate 2 to move downward until the top of the positioning plate 2 is flush with the assembly platform 11.

[0040] As Figure 2 and Figure 3As shown, the pressing assembly includes a pressing plate 13 and a seventh driving member (not shown in the figure) for driving the pressing plate 13 to move in the left-right direction. As an example, the seventh driving member is an electric push rod. The electric push rod extends in the left-right direction and is installed on the frame 1. The pressing plate 13 is fixedly connected to the driving end of the electric push rod. After all the heat dissipation tubes 9 of a radiator core are placed in the placement frame 3, a heat dissipation belt (not shown in the figure) is manually placed between adjacent heat dissipation tubes 9. After the heat dissipation belt is placed, the seventh driving member is controlled to drive the pressing plate 13 to abut against the heat dissipation tubes 9, and at the same time, the fourth driving member 12 is controlled to drive the positioning plate 2 to move downward, so that the positioning pins 21 are disengaged from the heat dissipation tubes 9. Then, the seventh driving member is controlled to drive the pressing plate 13 to pre-tighten the heat dissipation tubes 9 and the heat dissipation belt.

[0041] As Figure 2 and Figure 4 As shown, two assembly pushing blocks 4 are symmetrically arranged on the front and rear sides of the assembly platform 11, and a sixth driving member 41 for driving the two assembly pushing blocks 4 to move in the front-rear direction. As an example, the sixth driving member 41 is an electric push rod. The electric push rod extends in the front-rear direction and is installed on the frame 1. The assembly pushing block 4 is fixedly connected to the driving end of the electric push rod. Material boxes 5 are respectively arranged on the front and rear sides of the frame 1. A pushing component is arranged in the material box 5, and the side plates 10 for placing the radiator core are arranged in the material box 5. The pushing component includes a pushing plate 51 and a handle 52 fixedly connected to the pushing plate 51. The handle 52 extends through the material box 5 to the outside. A fourth spring 53 is arranged between the pushing plate 51 and the side wall of the material box 5.

[0042] A conveying component for transporting the side plate 10 upward is arranged between the material box 5 and the positioning plate 2. The fourth spring 53 drives the pushing plate 51 to push the side plate 10 onto the conveying component. During the process that the fourth driving member 12 drives the positioning plate 2 to move downward, the conveying component transports the side plate 10 upward. When the side plate 10 moves to a position opposite to the heat dissipation tubes 9, the sixth driving member 41 drives the assembly pushing block 4 to push the side plate 10 to be assembled on both sides of the heat dissipation tubes 9, and the assembly of the radiator core is completed.

[0043] Continue to refer to Figure 4, the conveying assembly includes a conveying plate 6 slidably arranged on the frame 1 in the vertical direction. Rack teeth 61 are respectively arranged on one side of the positioning plate 2 and the conveying plate 6 facing each other, and a transmission gear 14 is meshed between the two rack teeth 61. The transmission gear 14 is rotatably connected to the frame 1. During the downward movement of the positioning plate 2, the conveying plate 6 is driven to move upward through the cooperation of the rack teeth 61 and the transmission gear 14. An avoidance groove 23 for accommodating the rack teeth 61 and the transmission gear 14 is formed on the positioning plate 2, so that during the upward movement of the conveying plate 6, it always fits with the positioning plate 2. Only one side plate 10 can be accommodated at the upper end of the conveying plate 6 each time. During the upward movement of the conveying plate 6, the pushing plate 51 squeezes other side plates 10 against the conveying plate 6. During the upward movement of the positioning plate 2, the conveying plate 6 is driven to move downward through the cooperation of the rack teeth 61 and the transmission gear 14. When the conveying plate 6 moves below the side plate 10, the pushing plate 51 pushes a side plate 10 above the conveying plate 6, realizing the automatic feeding and assembly of the side plates 10, reducing manual participation and improving the assembly efficiency.

[0044] As Figures 4 to 8 shown, two lead screws 34 symmetrically arranged in the front-rear direction are arranged in the feeding frame 3, and the two lead screws 34 extend in the left-right direction. The pushing plate 31 is slidably connected to the feeding frame 3 in the left-right direction, and the pushing plate 31 is in threaded cooperation with the two lead screws 34. The second driving member includes tooth segments 7 arranged on the frame 1 at uniform intervals in the left-right direction, bevel gear one 35 fixedly connected to the end of the lead screw 34, and bevel gear two 36 rotatably connected to the feeding frame 3. The bevel gear two 36 is meshed with the bevel gear one 35, and a coaxially arranged driving gear 37 is fixedly connected to the bevel gear two 36.

[0045] During the process of the first driving member driving the feeding frame 3 to move from left to right, the driving gear 37 contacts and meshes with the tooth segment 7. The tooth segment 7 makes the driving gear 37 drive the bevel gear two 36 to rotate. The bevel gear two 36 drives the bevel gear one 35 and the lead screw 34 to rotate. The lead screw 34 drives the pushing plate 31 to move a distance equal to the thickness of a heat dissipation pipe 9 towards the feeding port 32. All the heat dissipation pipes 9 in the feeding frame 3 move towards the feeding port 32 under the pushing of the pushing plate 31, and the leftmost heat dissipation pipe 9 moves directly above the feeding port 32. When the driving gear 37 disengages from the tooth segment 7, the third driving member drives the stop baffle 33 to open the feeding port 32, and the heat dissipation pipe 9 drops from the feeding port 32 to the positioning grid 22. When the stop baffle 33 blocks the feeding port 32, the driving gear 37 contacts the next tooth segment 7, driving the pushing plate 31 to push the heat dissipation pipes 9 in the feeding frame 3, realizing the cyclic replenishment of the heat dissipation pipes 9.

[0046] As Figure 5 、 Figure 6 and Figure 9As shown in the figure, the stop plate 33 is elastically connected to the feeding frame 3 in the left - right direction through the third spring 331. The third driving member includes arc - shaped blocks 15 symmetrically arranged on the front and rear sides of the assembly platform 11. The arc - shaped blocks 15 are evenly spaced in the left - right direction on the frame 1 and are elastically connected to the frame 1 in the vertical direction. The front and rear sides of the stop plate 33 are fixedly connected with pushing columns 332. During the process of the feeding frame 3 moving from left to right, the pushing column 332 contacts the arc - shaped block 15, and the arc - shaped block 15 squeezes the pushing column 332 to drive the stop plate 33 to move leftward to open the feeding port 32. As the feeding frame 3 continues to move, the pushing column 332 squeezes the arc - shaped block 15 to move downward, and the pushing column 332 loses the block of the arc - shaped block 15. The stop plate 33 returns to the state of blocking the feeding port 32 under the elastic force of the third spring 331. When the pushing column 332 contacts the next arc - shaped block 15, the above process is repeated to intermittently open the feeding port 32.

[0047] It should be noted that the setting positions of the arc - shaped block 15 and the tooth section 7 need to meet the requirement that when the pushing column 332 disengages from the arc - shaped block 15, the driving gear 37 contacts the tooth section 7, driving the pushing plate 31 to push the heat dissipation tube 9 in the feeding frame 3 to move above the feeding port 32; when the driving gear 37 disengages from the tooth section 7, the arc - shaped block 15 squeezes the pushing column 332 to drive the stop plate 33 to open the feeding port 32, so that the heat dissipation tube 9 directly above the feeding port 32 automatically falls.

[0048] As Figures 6 to 8 shown in the figure, after the assembly of a radiator core is completed, the feeding frame 3 needs to move leftward to return above the assembly platform 11 for the next round of feeding of the heat dissipation tube 9. In order to prevent the tooth section 7 from forming a reverse drive on the driving gear 37 during the leftward movement of the feeding frame 3, causing the pushing plate 31 to move rightward, in this embodiment, the spaced - apart tooth sections 7 are fixedly connected to the same connecting plate 71, and a fifth driving member for driving the connecting plate 71 to drive the tooth section 7 to move vertically is arranged on the frame 1. When the feeding frame 3 moves leftward to return to the initial position, the fifth driving member first drives the connecting plate 71 to drive the tooth section 7 to move downward to a position where it does not interfere with the driving gear 37. When the feeding frame 3 re - feeds the heat dissipation tube 9, the fifth driving member then drives the connecting plate 71 to drive the tooth section 7 to move upward to reset.

[0049] As Figures 6 to 8 、 Figure 10As shown, a movable groove 16 is provided on the frame 1, and a connecting plate 71 is slidably installed in the movable groove 16 along the vertical direction, and a mounting rod 72 is fixedly connected to the bottom of the connecting plate 71. The driving member 5 includes a spring 1 73 arranged between the connecting plate 71 and the frame 1 and a push assembly arranged on the frame 1, and the push assembly includes a squeeze block 74 and a squeeze plate 75. The mounting rod 72 is provided with a mounting groove 721 adapted to the squeeze block 74, and the mounting groove 721 and the squeeze block 74 are respectively provided with matching inclined surfaces. A through hole 1 17 is provided on the frame 1 for the squeeze block 74 to move in the left and right direction, and a through hole 2 751 is provided on the squeeze plate 75 for the squeeze block 74 to move in the vertical direction. The squeeze block 74 is fixedly connected with a protrusion 741 extending into the through hole 1 17 and the through hole 2 751.

[0050] Two levers 18 are arranged at intervals along the left-right direction on the frame 1. The two levers 18 are respectively connected to the frame 1 for rotation, and the two levers 18 are respectively fixedly connected to the connecting rods 181, and the extrusion plate 75 is hinged to the two connecting rods 181. The delivery frame 3 is fixedly connected to a lever 2 38 located between the two levers 18. When the delivery frame 3 moves from left to right until the lever 2 38 drives the lever 18 on the right to rotate right, the lever 18 drives the extrusion plate 75 to move rightward through the connecting rod 181, and the extrusion plate 75 drives the extrusion block 74 to move rightward through the protrusion 741. The extrusion block 74 moves downward through the cooperation of the inclined surface to squeeze the installation rod 72, and the installation rod 72 drives the connecting plate 71 and the tooth segment 7 to move downward, and the connecting plate 71 compresses the spring 1 73. When the delivery frame 3 moves from right to left and resets, when the lever 2 38 pushes the lever 18 on the left to rotate left, the lever 18 drives the extrusion plate 75 to move leftward through the connecting rod 181, and the extrusion plate 75 drives the extrusion block 74 to move leftward through the protrusion 741. When the extrusion block 74 is aligned with the mounting groove 721 on the mounting rod 72, the elastic force of the spring 1 73 causes the connecting plate 71 to drive the mounting rod 72 and the tooth segment 7 to move upward and reset.

[0051] In order to ensure that the tooth segment 7 remains in a state of extending upward or retracting downward, it is necessary to keep the lever 18 in the position after being moved. In this embodiment, a limit plate 19 is fixedly connected to the frame 1, and a through slot 191 is provided on the limit plate 19. The lever 18 passes through the through slot 191. A movable block 182 is slidably provided on the lever 18. The movable block 182 is elastically connected to the lever 18 along the extension direction of the lever 18 through a spring 2 183. The elastic force of the spring 2 183 causes the movable block 182 to abut against the bottom of the limit plate 19.

[0052] When the delivery frame 3 drives the lever 2 38 to move the lever 18 on the right side to rotate rightward, the limit plate 19 first squeezes the movable block 182 to move in the direction of compressing the spring 2 183. When the top of the lever 18 deflects to the right, the spring 2 183 releases the elastic force, so that the movable block 182 abuts against the bottom of the limit plate 19, increasing the resistance of the lever 18 to rotate to the left, so that the lever 18 remains in the position after deflection. When the delivery frame 3 drives the lever 2 38 to move the lever 18 on the left side to rotate leftward, the movable block 182 on the lever 18 also first compresses the spring 2 183. When the top of the lever 18 deflects to the left, the spring 2 183 releases the elastic force, so that the movable block 182 abuts against the bottom of the limit plate 19, increasing the resistance of the lever 18 to rotate to the right, so that the lever 18 remains in the position after deflection.

[0053] Continue reading Figure 7 and Figure 8 After all the heat dissipation tubes 9 in the delivery frame 3 are delivered, new heat dissipation tubes 9 need to be added to the delivery frame 3. Therefore, before placing the new heat dissipation tubes 9, the push plate 31 needs to be restored to the initial position. In this embodiment, the bevel gear 2 36 is fixedly connected with the coaxially arranged bevel gear 3 39, and a bevel gear 4 8 is installed at the middle position on the right side of the delivery frame 3. A rotating rod 81 is arranged between the bevel gear 3 39 and the bevel gear 4 8. The rotating rod 81 is rotatably connected to the delivery frame 3, and the two ends of the rotating rod 81 are respectively fixedly connected with the bevel gear 5 82 meshing with the bevel gear 3 39 and the bevel gear 6 83 meshing with the bevel gear 4 8. By driving the bevel gear 4 8 to rotate, the bevel gear 4 8 drives the bevel gear 3 39 to drive the bevel gear 2 36 to rotate through the cooperation of the bevel gear 6 83 and the bevel gear 5 82, and the bevel gear 2 36 drives the lead screw 34 to drive the push plate 31 to move to the initial position.

[0054] The specific working principle of the radiator assembly tool of the present invention is as follows: the heat pipes 9 are arranged and placed in the delivery frame 3, the initial position of the delivery frame 3 is located directly above the assembly platform 11, the initial positions of the two positioning plates 2 are located at the front and rear sides of the assembly platform 11, and the positioning pins 21 on the positioning plates 2 form a positioning grid 22; The control driving member 1 drives the delivery frame 3 to move from left to right, the push column 332 on the stop plate 33 contacts the arc block 15, the arc block 15 squeezes the push column 332 to drive the stop plate 33 to move to the left to open the delivery port 32, and the heat dissipation pipe 9 falls from the delivery port 32 to the positioning grid 22; During the process of the placement frame 3 continuing to operate, the top push column 332 presses the arc-shaped block 15 downward, and the stop baffle 33 returns to the state of blocking the placement opening 32 under the elastic force of the third spring 331. At this time, the driving gear 37 contacts the tooth section 7, and the tooth section 7 causes the driving gear 37 to drive the second bevel gear 36 to rotate. The second bevel gear 36 drives the first bevel gear 35 and the lead screw 34 to rotate, and the lead screw 34 drives the top push plate 31 to push all the heat dissipation tubes 9 in the placement frame 3 toward the placement opening 32, realizing the replenishment of the heat dissipation tubes 9 above the placement opening 32; Subsequently, the driving gear 37 disengages from the tooth section 7, the top push column 332 contacts the next arc-shaped block 15, and the placement opening 32 is opened again. The heat dissipation tube 9 automatically drops into the next positioning grid 22. After that, the top push column 332 disengages from the arc-shaped block 15, the stop baffle 33 closes the placement opening 32 again, and the driving gear 37 contacts the next tooth section 7, causing the top push plate 31 to push the heat dissipation tubes 9 in the placement frame 3 toward the placement opening 32 again. By repeating this process, the cyclic placement of the heat dissipation tubes 9 is realized; After the placement of the heat dissipation tubes 9 of the radiator core is completed, heat dissipation belts are placed into two adjacent heat dissipation tubes 9. Then, control the seventh driving member to drive the pressing plate 13 to abut against the heat dissipation tubes 9, and at the same time control the fourth driving member 12 to drive the positioning plate 2 to move downward. After the positioning pins 21 disengage from the heat dissipation tubes 9, the pressing plate 13 pre-tightens the heat dissipation tubes 9 and the heat dissipation belts; During the process of the positioning plate 2 moving downward, the conveying plate 6 is driven to move upward through the cooperation of the rack 61 and the transmission gear 14. When the conveying plate 6 pushes the side plate 10 to a position opposite to the heat dissipation tube 9, the sixth driving member 41 drives the assembly push block 4 to push the side plate 10 to be assembled on both sides of the heat dissipation tube 9, completing the assembly of the radiator core.
