Description

Technical Field

[0001] This invention relates to the field of automotive evaporators, and more specifically to an automotive evaporator core assembly system and a method for assembling automotive evaporator cores. Background Technology

[0002] The automotive evaporator core includes: a first manifold module, a second manifold module, a first side plate, a second side plate, edge plates, fins, and flat tubes. There are multiple flat tubes, which are fixed to the fins. There are also multiple fins, and the flat tubes on the fins are parallel to each other. The first side plate connects one end of all the fins, and the second side plate connects the other end of all the fins. The first manifold module is installed on the first side plate, and the second manifold module is installed on the second side plate. The first manifold module and the second manifold module have connecting channels that connect the flat tubes, thereby forming a flow channel with a specified path. There are two edge plates, and fins are placed between the two edge plates.

[0003] In the existing technology, the assembly steps of the automotive evaporator core are as follows: Step 1: Using a welding machine, fix the flat tube to the fins; Step 2: Stack the fins with flat tubes in a flat tube fin assembly device, so that the fins with flat tubes are in a specified assembly state, place the fins between the two edge plates, and clamp all the fins between the two edge plates to obtain the pre-assembled fins; Step 3: Transfer the pre-assembled fins to the side plate assembly device, which is used to assemble the first and second side plates of the side plate structure to the ends of the pre-assembled fins to obtain a semi-finished chip assembly; Step 4: Place the semi-finished chip assembly on the manifold assembly device, and install the first and second manifold modules on the semi-finished chip assembly to obtain the assembled core product; Step 5: Place the assembled core product on the core unloading device, which bundles the assembled core product.

[0004] While the above steps can achieve the production of finished automotive evaporator cores, the following drawbacks remain: In step two, after all the fins with flat tubes are neatly stacked together, there is no positioning and clamping fixture. As a result, the fins move randomly during the transfer of the pre-assembled fins to the side plate assembly device. This leads to disordered pre-assembled fins before they even reach the side plate assembly device. The disordered pre-assembled fins cannot be assembled with the first and second side plates, requiring rework in step two and reducing production efficiency. Summary of the Invention

[0005] The present invention provides an automotive evaporator core assembly system and an automotive evaporator core assembly method, which solves the problem in the prior art that the fins obtained after the preliminary assembly in step two are easily misaligned due to the lack of positioning and clamping fixtures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This invention first discloses an automotive evaporator core assembly system, comprising: a fin assembly device, which includes: a working platform, assembly tracks, end blocks, a horizontal pressing actuator, and a vertical leveling device. Two parallel assembly tracks are installed on the working platform. The assembly tracks are used to store stacked fins with flat tubes and edge plates. An end block is provided at one end of each assembly track, and a horizontal pressing actuator is provided at the other end. The horizontal pressing actuator is used to press the stacked fins with flat tubes and edge plates onto the end block. A vertical leveling device is installed on the working platform, spanning the assembly tracks and the horizontal pressing actuator. The vertical leveling device is used to level the fins between the two assembly tracks. After the fin assembly device performs its operation, a preliminary assembled fin is obtained. A positioning and clamping fixture is used to clamp the preliminary assembled fin. A side plate assembly device is used to assemble a first side plate and a second side plate onto the preliminary assembled fin clamped by the positioning and clamping fixture.

[0008] Preferably, the positioning and clamping fixture includes: a first clamping arm, a second clamping arm, a fixture base, and an adjusting positioning mechanism. The first clamping arm is fixed at one end of the fixture base, and the movable second clamping arm is installed at the other end of the fixture base. The first clamping arm is used to be in close contact with one edge plate of the fin, and the second clamping arm is used to be in close contact with the other edge plate of the fin. An adjusting positioning mechanism is installed on the fixture base. The adjusting positioning mechanism is used to keep the second clamping arm pressed against the edge plate after acting with the second clamping arm.

[0009] Preferably, the adjusting positioning mechanism includes: a first hinge seat, a second hinge seat, a guide cylinder, a push arm, a first spring, a pull rod, and an auxiliary rotating arm. The first hinge seat and the second hinge seat are installed on the tooling base. The first hinge seat is located next to the first clamping arm, and the second hinge seat is located next to the second clamping arm. The second hinge seat is hinged to one end of the guide cylinder. The push arm and the first spring are installed inside the guide cylinder. The push arm is fixed to one end of the pull rod, and the pull rod passes through the other end of the guide cylinder. The other end of the pull rod is hinged to the middle of the auxiliary rotating arm. The first end of the auxiliary rotating arm is hinged to the first hinge seat. The first spring can keep the push arm close to the second hinge seat. The auxiliary rotating arm and the first hinge seat can be positioned by friction. The push arm is used to push the second clamping arm to press against the edge plate.

[0010] Preferably, the second clamping arm is fixed with a passive block located below the push arm, and the passive block has an L-shaped structure.

[0011] Preferably, the passive block is equipped with a rotatable roller for contacting the push arm.

[0012] Preferably, the horizontal clamping actuator includes a pusher seat and a pusher cylinder, the pusher seat is connected to the output end of the pusher cylinder, the pusher seat is located between two assembly tracks, and the pusher seat is fixed to the output end of the pusher cylinder.

[0013] Preferably, a hook block is installed on the push arm, the push cylinder pushes in the X direction, and the hook block prevents the edge plate from disengaging from the push arm in the X direction.

[0014] Preferably, there are two hook blocks. The hook blocks hook onto the side edge of the edge plate. The hook blocks are fixed with a movable block. Both the movable block and the hook blocks can move relative to the push seat in the Z direction. A second spring is installed between the two hook blocks. The second spring is used to keep the hook blocks hooked onto the edge plate. The second end of the auxiliary rotating arm is used to release the hook blocks from the edge plate by squeezing the movable block.

[0015] This invention also discloses a method for assembling an automotive evaporator core, comprising the following steps:

[0016] S1. Place the fins with flat tubes and edge plates between the two assembly tracks, and use the hook block on the push arm to hook one edge plate, with the other edge plate in close contact with the end block. All fins with flat tubes are close to the fins in close contact with the end block.

[0017] S2. Start the push cylinder, and the edge plate at the hook block contacts the fins;

[0018] S3. Use a vertical leveling device to level the fins located between the two edge plates;

[0019] S4. Restart the push cylinder so that the edge plate at the hook block presses all the fins onto the end block, resulting in the pre-assembled fins.

[0020] S5. Use a positioning clamping fixture to clamp the pre-assembled fins and transfer the clamped pre-assembled fins to the side plate assembly device.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In this application, a positioning and clamping fixture is added to the original design. The fin assembly device simply stacks the fins and edge plates together in a regular manner and maintains a tight contact state to ensure that the fins can be inserted into the first and second side plates. The positioning and clamping fixture is used to maintain the state of the fins after the initial assembly and before the side plate assembly device assembles the first and second side plates, so as to ensure that the subsequent assembly work can proceed smoothly.

Detailed Implementation

[0032] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0033] Example 1:

[0034] like Figures 1 to 6 As shown, this embodiment discloses an automotive evaporator core assembly system, including: a fin 11 assembly device, which includes: a working platform 21, assembly rails 22, end blocks 23, a horizontal pressing actuator 24, and a vertical leveling device 25. Two parallel assembly rails 22 are installed on the working platform 21. The assembly rails 22 are used to store stacked fins 11 with flat tubes and edge plates 12. One end of the assembly rail 22 is provided with an end block 23, and the other end of the assembly rail 22 is provided with a horizontal pressing actuator 24, which is used to hold the stacked fins 11. The fins 11 with flat tubes and the edge plates 12 are pressed onto the end blocks 23. A vertical leveling device 25 is installed on the working platform 21, which spans the assembly track 22 and the horizontal pressing actuator 24. The vertical leveling device 25 is used to level the fins 11 between the two assembly tracks 22. After the fin assembly device is executed, the fins 11 are obtained after preliminary assembly. A positioning clamping fixture 3 is used to clamp the fins 11 after preliminary assembly. A side plate assembly device is used to assemble the first side plate and the second side plate onto the fins 11 after preliminary assembly that are clamped by the positioning clamping fixture 3.

[0035] The positioning and clamping fixture 3 includes: a first clamping arm 31, a second clamping arm 32, a fixture base 33, and an adjusting positioning mechanism 34. The first clamping arm 31 is fixed at one end of the fixture base 33, and the second clamping arm 32, which can move, is installed at the other end of the fixture base 33. The first clamping arm 31 is used to be tightly attached to one side edge plate 12 of the fin 11, and the second clamping arm 32 is used to be tightly attached to the other side edge plate 12 of the fin 11. The adjusting positioning mechanism 34 is installed on the fixture base 33. The adjusting positioning mechanism 34 is used to keep the second clamping arm 32 pressed against the edge plate 12 after acting with the second clamping arm 32.

[0036] The adjusting positioning mechanism 34 includes: a first hinge seat 341, a second hinge seat 342, a guide cylinder 343, a push arm 344, a first spring 345, a pull rod 346, and an auxiliary rotating arm 347. The first hinge seat 341 and the second hinge seat 342 are mounted on the tooling base 33. The first hinge seat 341 is located beside the first clamping arm 31, and the second hinge seat 342 is located beside the second clamping arm 32. The second hinge seat 342 is hinged to one end of the guide cylinder 343. The push arm 345 is installed inside the guide cylinder 343. 4 and the first spring 345, the push arm 344 is fixed to one end of the pull rod 346, the pull rod 346 passes through the other end of the guide cylinder 343, the other end of the pull rod 346 is hinged to the middle of the auxiliary rotating arm 347, the first end of the auxiliary rotating arm 347 is hinged to the first hinge seat 341, the first spring 345 can keep the push arm 344 close to the second hinge seat 342 under the elastic force, the auxiliary rotating arm 347 and the first hinge seat 341 can be positioned by friction, and the push arm 344 is used to push the second clamping arm 32 to press against the edge plate 12. Before clamping, the first clamping arm 31 and the second clamping arm 32 are in the open state, that is, the second clamping arm 32 is in the movable state. Under the elastic force of the first spring 345, the push arm 344 is in the state close to the second hinge seat 342. At this time, the first end of the auxiliary rotating arm 347 is lower than the second end, and the hinge point between the pull rod 346 and the auxiliary rotating arm 347 is located above the first end of the auxiliary rotating arm 347. At this time, the push arm 344 has no squeezing effect on the roller 322 on the second clamping arm 32. In use, the first clamping arm 31 and the second clamping arm 32 are placed on both sides of the two edge plates 12 respectively; then, the auxiliary rotating arm 347 is rotated so that the second end of the auxiliary rotating arm 347 tilts downwards, and finally the auxiliary rotating arm 347 is in close contact with the first hinge seat 341. The auxiliary rotating arm 347 is rotated to the tilted position, and the hinge of the pull rod 346 and the auxiliary rotating arm 347 moves away from the second hinge seat 342. The pull rod 346 pulls the push arm 344 to the state of pressing against the roller 322. The second clamping arm 32 and the first clamping arm 31 cooperate to clamp all the fins 11 and the edge plates 12. The middle part of the auxiliary rotating arm 347 is positioned with the first hinge seat 341 by friction welding, thereby positioning the state in which the second clamping arm 32 and the first clamping arm 31 cooperate to clamp all the fins 11 and the edge plates 12.

[0037] The second clamping arm 32 is fixed with a passive block 321 located below the push arm 344. The passive block 321 has an L-shaped structure.

[0038] The passive block 321 is equipped with a rotatable roller 322, which is used to contact the push arm 344.

[0039] The horizontal pressing actuator 24 includes a pusher seat 241 and a pusher cylinder 242. The pusher seat 241 is connected to the output end of the pusher cylinder 242. The pusher seat 241 is located between two assembly tracks 22. The pusher seat 241 and the output end of the pusher cylinder 242 are fixed.

[0040] A hook block 243 is installed on the push arm 344. The push direction of the push cylinder 242 is the X direction. The hook block 243 prevents the edge plate 12 from disengaging from the push arm 344 in the X direction.

[0041] There are two hook blocks 243. The hook blocks 243 hook the side edge of the edge plate 12. The hook blocks 243 are fixed with a moving block 244. Both the moving block 244 and the hook blocks 243 can move relative to the push seat 241 in the Z direction. A second spring (not shown in the figure) is installed between the two hook blocks 243. The second spring is used to keep the hook blocks 243 hooked to the edge plate 12. The second end of the auxiliary rotating arm 347 is used to release the hook blocks 243 from the edge plate 12 by squeezing the moving block 244.

[0042] In this application, firstly, to ensure that the fins 11 obtained by the fin assembly device after preliminary assembly do not become loose or deformed before assembling the first and second side plates, a positioning clamping fixture 3 is designed to maintain the state of the fins 11 after preliminary assembly until the first and second side plates are assembled. Secondly, the second clamping arm 32 of the positioning fixture is movable, and the second clamping arm 32 is positioned by adjusting the positioning mechanism 34. This allows the second clamping arm 32 and the first clamping arm 31, which are open to each other, to be placed outside the two side edge plates 12 before clamping. Then, the second clamping arm 32 is positioned by adjusting the positioning mechanism 34. The clamping arm 32 is pressed against the edge plate 12 to maintain a clamped state and prevent the fins 11 from loosening during the initial assembly process. Furthermore, to ensure that the adjusting positioning mechanism 34 can pull the second clamping arm 32 and simultaneously position it, a first hinge seat 341, a second hinge seat 342, a guide cylinder 343, a push arm 344, a first spring 345, a pull rod 346, and an auxiliary rotating arm 347 are designed. Rotating the auxiliary rotating arm 347 allows the pull rod 346 and push arm 344 to pull the second clamping arm 32, thus enabling the second clamping arm 32 to cooperate with the first clamping arm 31 to clamp the fins. 11, and this state is maintained through the friction between the auxiliary rotating arm 347 and the first hinge seat 341; then, in order to be able to be pushed by the push arm 344, a passive block 321 and a roller 322 are designed on the second clamping arm 32. The roller 322 makes the contact between the roller and the push arm 344 smoother, avoiding wear that could lead to insufficient clamping force; then, a push cylinder 242 and a push arm 344 are designed to press the fin 11 and the edge plate 12 together; then, a hook block 243 is designed to position the edge plate 12 before pressing, to avoid the edge plate 12 being unable to be positioned at the beginning; finally A second spring was designed to keep the hook block 243 in the position of the positioning edge plate 12. At the same time, the movable block 244 on the hook block 243 and the auxiliary rotating arm 347 were designed to cooperate, so that after the fin 11 and the edge plate 12 are pressed together (the fin 11 is equipped with a flat tube, so there is a small gap between the fin 11 and the edge plate 12, which allows the hook block 243 to extend in), the auxiliary rotating arm 347 rotates to the position, that is, the positioning clamping fixture 3 has maintained the state of clamping the fin 11 and the edge plate 12. At this time, the auxiliary rotating arm 347 rotates to the position, which also makes the hook block 243 automatically release the edge plate 12, avoiding the need to waste time adjusting the hook block 243 later.

[0043] The movable block 244 has a triangular structure. The contact surface between the movable block 244 and the auxiliary rotating arm 347 is a first inclined surface. The first inclined surfaces of the two movable blocks 244 form a V-shaped structure. The auxiliary rotating arm 347 extends between the two first inclined surfaces. The surface of the auxiliary rotating arm 347 that contacts the first inclined surface is an arc surface. This ensures that the auxiliary rotating arm 347 can rotate smoothly between the two first inclined surfaces.

[0044] The vertical leveling device 25 includes: a support frame 250, a guide rod 251, a movable seat 252, a lifting seat 253, a hinge rod 254, a leveling seat 255, a push rod 256, a leveling roller 257, and a lifting frame 258. The support frame 250 is mounted on the work platform 21. The guide rod 251 is mounted on the support frame 250, and the guide rod 251 guides the movable seat 252 to move in the X direction. The movable seat 252 is equipped with a lifting seat 253 that can be raised and lowered. A hinge rod 254 is installed on the lowering seat 253. The hinge rod 254 is located in the Z direction and is hinged to the top of the leveling seat 255. A rotatable leveling roller 257 is installed at the bottom of the leveling seat 255. A rotatable lifting frame 258 is installed on the moving seat 252. One end of the lifting frame 258 is a push-hand end, and the other end is a lifting end. The lifting end is located below the lowering seat 253. A push rod 256 is installed below the hinge of the lifting frame 258.

[0045] Under the weight of the lifting seat 253, hinge rod 254, leveling seat 255, and leveling roller 257, the leveling roller 257 can be kept in contact with the fin 11. At this time, the raised end of the lifting frame 258 is pressed down to the lowest position by the lifting seat 253. Since the leveling seat 255 and the leveling roller 257 can rotate around the hinge rod 254, the leveling roller 257 is prevented from colliding hard with the fin 11 when the fin 11 protrudes too much, thus avoiding damage to the fin 11. When there is a collision, the leveling roller 257 and the leveling seat 255 can rotate around the hinge rod 254, thereby reducing the damage to the fin 11. When the leveling roller 257 moves above the fin 11, there will inevitably be some friction between the leveling roller 257 and the fin 11. Therefore, the leveling roller 257 can rotate itself, further reducing the damage to the fin 11.

[0046] A lifting seat 259, which can pass through the movable seat 252, is fixed on the support frame 250. The top surface of the lifting seat 259 is a raised surface, and the angle between the raised surface and the horizontal plane is an acute angle. The raised surface is inclined towards the working position, which is the position where the fins 11 and the edge plate 12 are clamped. The raised surface is used to lift the leveling roller 257 when it moves away from the working position. This avoids the leveling roller 257 remaining in a low position after moving away from the working position, which would prevent the leveling roller 257 from blocking the passage of the movable block 244 and causing it to be damaged. Since the movable block 244 needs to be squeezed against the auxiliary roller, it is in a high position, and the leveling roller 257 is very likely to cause the movable block 244 to break.

[0047] Example 2:

Place the fins 11 with flat tubes and the edge plates 12 between the two assembly tracks 22, and use the hook block 243 on the push arm 344 to hook one edge plate 12, and the other edge plate 12 is in close contact with the end block 23. All the fins 11 with flat tubes are close to the fins 11 that are in close contact with the end block 23.

[0050] S2. Start the push cylinder 242, and the edge plate 12 located at the hook block 243 contacts the fin 11;

[0051] S3. Use vertical leveling device 25 to level the fins 11 located between the two edge plates 12;

[0052] S4. Restart the push cylinder 242 so that the edge plate 12 at the hook block 243 presses all the fins 11 onto the end block 23, and obtains the fins 11 after preliminary assembly.
