TECHNICAL FIELD
[0001] The present application relates to the technical field of new energy vehicle air conditioning, in particular to an intelligent system for bundling and spacer inserting of an automobile air conditioner evaporator and a use method thereof. BACKGROUND
[0002] In recent years, a large number of automobile air conditioning systems use evaporators similar or identical to the main structure in document CN210035946U. The main structure of such an evaporator mainly consists of a manifold, a partition plate (also known as a spacer), a side plate, a flat tube, and a fin. The partition plate is installed in the mounting hole of the manifold.
[0003] With the development of industrial intelligent control technology, many automobile parts factories have adopted intelligent evaporator manufacturing equipment / systems to produce automobile air conditioner evaporators. Currently, typical evaporator manufacturing equipment / systems, such as the evaporator assembly machine developed and popularized by Shanghai Shuma Technology Co., Ltd., mainly include a fin forming device, a fin conveying system, a flat tube array mechanism, an evaporator core assembly mechanism, an evaporator core bundling mechanism, and an evaporator core conveying mechanism. During use, the manifold, side plate, flat tube, and fin are assembled together by the evaporator core assembly mechanism to form an evaporator core, and then the evaporator core is tightly bundled with a wire before being moved to a brazing furnace for welding.
[0004] Among them, the main structure of the evaporator core bundling mechanism is described in documents CN211663518U (double-head simultaneous steel wire bundling mechanism), CN106428708A (heat exchanger core bundling machine), CN206107639U (heat exchanger bundling machine wire cutting and knotting device), and CN206107635U (bundling machine telescopic traction head device). The main technical route for bundling with this several is as follows: first, fix the evaporator core, then pull the steel wire joint from below the evaporator core (from one side of the evaporator core to the other side) with the help of a pulling module, then push the steel wire joint upwards, then pull the steel wire joint back from above the evaporator core with another pulling module, until the pulled steel wire wraps around the evaporator core once, then cut the steel wire root, and finally use a rotating clamp to tighten the steel wire joint part, so that the steel wire is tightly wrapped around the evaporator core.
[0005] However, using this technical route can cause damage to the side plate of the evaporator core, especially the appearance of a deep 4mm recess on the side plate of the evaporator core.
[0006] More importantly, during the manufacturing process of the evaporator core, the partition plate also needs to be installed in the mounting hole of the header pipe. Since the partition plate is small (the length is consistent with the diameter of the inner cavity of the header pipe, only about 30 mm, and the width is about 12 mm) and thin (only about 3-5 mm), it is currently mainly installed by manual operation, which is low in installation efficiency and inconvenient to operate. Usually, after the evaporator core is bundled, the operator first clamps the partition plate and inserts it into the mounting hole, and then adjusts it to the right position. For example, it takes an average of about thirty seconds for each worker to install the partition plates on each evaporator core. Therefore, how to quickly install the partition plate in place during the bundling process of the evaporator core is a problem to be solved, which can at least reduce one independent station and one manual operation. SUMMARY
[0007] At least for the technical problems mentioned in the background, the present application aims to provide an intelligent system for bundling and partition plate installation of an automobile air conditioner evaporator and a method thereof.
[0008] The present application adopts the following technical solutions.

The rectangular bundling steel strip is sleeved on the evaporator core by the grabbing mechanism after the rectangular bundling steel strip is grabbed, and the rectangular bundling steel strip on the evaporator core is tightened and locked by the tightening mechanism.
[0011] The partition plate installation mechanism comprises a steel needle connected to the front end of a first horizontal cylinder. After the steel needle is inserted into the blind hole of the partition plate, the steel needle is moved forward by the extension rod of the first horizontal cylinder to realize the horizontal insertion of the partition plate into the partition plate mounting hole on the evaporator core.
[0012] As a preferred solution, the partition plate installation mechanism further comprises a material box for accommodating the partition plate, a material passing channel is arranged at the lower part of the material box, the material passing channel can temporarily store one partition plate, the material passing channel, the steel needle and the partition plate mounting hole are located at the same horizontal linear position, the extension rod of the first horizontal cylinder is connected to a flat plate, the flat plate is integrally formed with the steel needle, the height and thickness of the flat plate are consistent with the corresponding size of the material passing channel, and the flat plate can pass through the material passing channel.
[0013] As a preferred solution, the bundling mechanism comprises vertically arranged telescopic device A and horizontally arranged telescopic device B, the telescopic rod of telescopic device A is arranged upward and connected with the clamping jaw A, the telescopic rod of telescopic device B is arranged toward the bundling station and connected with the clamping jaw B; the clamping jaw A can clamp and pull down the rectangular bundled steel band joint sleeved on the evaporator core, and the clamping jaw B can clamp and press the locking piece on the rectangular bundled steel band.
[0014] As a preferred solution, the grabbing mechanism comprises second horizontal cylinder and second vertical cylinder, the second vertical cylinder is connected with the telescopic rod of the second horizontal cylinder, the telescopic rod of the second vertical cylinder is provided with vacuum suction cup at the lower end, the vacuum suction cup is in strip shape, and the length of the vacuum suction cup is equal to 3 / 4 to 1 times of the length of the long side of the rectangular bundled steel band.
[0015] In order to more conveniently grab the rectangular bundled steel band, the rack is a flat plate.
[0016] As a preferred solution, the grabbing mechanism and the bundling mechanism are symmetrically arranged with two sets of the center line of the bundling station as the symmetric axis.
[0017] Further, the grabbing mechanism, the bundling mechanism, the two-dimensional moving mechanism and the evaporator clamping mechanism are connected with the control system and control the operation thereof.
[0018] A use method / bundling method using the foregoing intelligent system, characterized in that the control system comprises a memory, a processor and a program stored in the memory and capable of running on the processor, and the processor can realize the following steps when executing the program:
[0019] Step 1, first control the two-dimensional moving mechanism to move to the material taking station, then control the evaporator clamping mechanism to work to clamp the evaporator core at the material taking station, then control the two-dimensional moving mechanism to move to drive the evaporator core to move to the bundling station, and always clamp the evaporator core at the bundling station;
[0020] Step 2, first control the second horizontal cylinder and the second vertical cylinder to move the vacuum suction cup to the target position one to grab one rectangular bundled steel band; then continue to control the second horizontal cylinder and the second vertical cylinder to move the vacuum suction cup to the target position two, at this time, the rectangular bundled steel band is sleeved on the evaporator core;
[0021] Step 3, first control the first horizontal cylinder to move forward to insert the steel needle into the blind hole of the partition piece, and drive the partition piece to be horizontally inserted into the partition piece mounting hole on the evaporator core, then control the first horizontal cylinder to reset;
[0022] Step 4, first control the action of the telescopic device B and the clamping jaw B to make the clamping jaw B clamp the locking piece; then control the telescopic device A to extend upward and the action of the clamping jaw A to make the clamping jaw A clamp the rectangular baling steel band joint; then control the second horizontal air cylinder and the second vertical air cylinder to reset; then control the telescopic device A to retract to realize the tensioning of the rectangular baling steel band; then control the action of the clamping jaw B to clamp the locking piece, and then control the clamping jaw A and the clamping jaw B to release, and then control the telescopic device A and the telescopic device B to reset;
[0023] Step 5, control the two-dimensional moving mechanism to move and the action of the evaporator clamping mechanism to place the evaporator core on the conveying belt and then reset;
[0024] Step 6, repeat steps 1-5 to bale and install the spacer for the next evaporator core.
[0025] As a preferred solution, the rectangular baling steel band is hung on the rack.
[0026] In order to be able to bale more stably, the wall thickness of the rectangular baling steel band is not greater than 1mm, the rectangular baling steel band adopts carbon steel band or stainless steel band, and the surface of the rectangular baling steel band is provided with a plurality of anti-skid parts arranged at intervals, which is more conducive to locking.
[0027] Beneficial effects: by adopting the solution, not only can the edge plate of the evaporator core be prevented from being damaged, and no pits will appear on the edge plate of the evaporator core, but also the spacer on the evaporator core can be quickly, stably and smoothly installed in place during the baling of the evaporator core, without the need for separate additional manual installation of the spacer, thereby saving the labor for installing the spacer; by adopting the solution, the spacer on an evaporator core can be installed every five seconds on average, which is high in efficiency and fundamentally avoids the inconvenience of installing the spacer in the traditional way.
[0028] Since the rectangular baling steel band is relatively thin and soft and has large elasticity, the traditional solution (the baling technical route in the background art) can only still adopt the mode of pulling and winding the steel band before tightening, but this mode is prone to causing the steel band to break, and the steel band is extremely easy to string and fall off in the moment of being cut, which has to be equipped with four sets of clamps specially used for clamping the steel band (one set of clamp for clamping the end of the steel band to facilitate feeding, one set of clamp for fixing the root of the steel band after being pulled, one set of clamp for pulling back the end of the steel band, and one set of clamp for rotating the steel band when tightening the steel band), so that the whole baling structure is very complex and occupies a large space. By adopting the solution, the top edge of the rectangular baling steel band is grabbed by the strip-shaped suction cup, and the rectangular baling steel band can be directly sleeved on the evaporator core by means of the air cylinder, and then only two sets of clamps and the corresponding telescopic devices are needed to quickly bale the evaporator core, so that the structure is simpler and the occupied space can be reduced by nearly one third compared with the traditional solution.
[0029] In the present application, the rectangular binding steel belt and the spacer are made in batches in advance. In the spacer installation process, the steel needle is inserted into the blind hole on the spacer, and the spacer can be quickly installed by using the cylinder and the steel needle to carry the spacer. The steel needle and the spacer do not interfere with the rectangular binding steel belt during the forward movement, and the effect of almost synchronous installation of the evaporator binding and the spacer insertion is achieved. In addition, after the spacer is inserted, it is tightened, which better ensures that the spacer can be smoothly and stably inserted into the spacer installation hole. BRIEF DESCRIPTION OF DRAWINGS

[0064] Embodiment 2
[0065] The intelligent system for bundling and inserting the evaporator core in the embodiment is the same as that in embodiment 1, and the main difference between the two embodiments is that the gasket inserting mechanism is controlled to work to install the gasket 6 in place first, and then the rectangular bundling steel belt 21 is sleeved and bundled. Specifically, a stainless steel belt with a wall thickness of 0.5 mm is used as the rectangular bundling steel belt 21, and a plurality of anti-slip parts are arranged on the surface of the rectangular bundling steel belt 21, and the protruding part of the anti-slip part is 0.15 mm. When the processor executes the program, the following steps are implemented:
[0066] Step 21, first control the two-dimensional moving mechanism 2 to move to the material taking station 4 (the state is as shown in Figure 1 ), then control the evaporator clamping mechanism 3 to work to clamp the evaporator core 5 at the material taking station 4 (the state is as shown in Figure 2 ), then control the two-dimensional moving mechanism 2 to move to drive the evaporator core 5 to the bundling station, and always clamp the evaporator core 5 at the bundling station;
[0067] Step 22, as shown in Figures 3 to 7 , first control the first horizontal cylinder 40 to act to make the steel needle 41 forwardly move to insert into the blind hole 61 of the gasket 6, and drive the gasket 6 to be horizontally inserted into the gasket mounting hole 62 on the evaporator core 5, then control the first horizontal cylinder 40 to reset;
[0068] Step 23, first control the second horizontal cylinder 11 and the second vertical cylinder 12 to act to make the vacuum suction cup 13 move to the target position one to grab one rectangular bundling steel belt 21; then continue to act the second horizontal cylinder 11 and the second vertical cylinder 12 to make the vacuum suction cup 13 move to the target position two, and at this time, the rectangular bundling steel belt 21 is sleeved on the evaporator core 5;
[0069] Step 24, as shown in Figure 8As shown, first control the action of the telescopic device B51 and the clamping jaw B53 to make the clamping jaw B53 clamp the locking piece 23; then control the upward extension of the telescopic device A50 and the action of the clamping jaw A52 to make the clamping jaw A52 clamp the joint of the rectangular bundling steel belt 21; then control the reset of the second horizontal air cylinder 11 and the second vertical air cylinder 12; then control the retraction of the telescopic device A50 to realize the tensioning of the rectangular bundling steel belt 21; then control the action of the clamping jaw B53 to clamp the locking piece 23, and then control the release of the clamping jaw A52 and the clamping jaw B53, and then control the reset of the telescopic device A50 and the telescopic device B51;
[0070] Step 25: control the two-dimensional moving mechanism 2 to move and control the action of the evaporator clamping mechanism 3 to place the evaporator core 5 on the conveying belt 10 and then reset;
[0071] Step 26: repeat steps 1-5 to bundle and install the spacers for the next evaporator core 5.
[0072] In the present application, the rectangular bundling steel belt 21 and the spacers 6 are pre-made in batches. During the manufacturing process, the blind hole 61 is processed on the spacer 6, which can meet the requirements of the insertion and removal of the steel needle 41; the rectangular bundling steel belt 21 is pre-made and in a rectangular shape in a flat state, the end segment of the rectangular bundling steel belt 21 is inserted into the locking piece 23 (as shown), the rectangular space area of the rectangular bundling steel belt 21 is larger than the cross-sectional area of the evaporator core 5, so that the rectangular bundling steel belt 21 can be sleeved on the evaporator core 5, and the joint of the rectangular bundling steel belt 21 can be pulled to bundle the evaporator core 5, which is similar to the pulling of the joint of the nylon bundling belt during the bundling process; the locking piece 23 used on the rectangular bundling steel belt 21 can adopt a steel locking piece used on a plastic steel packing belt, or a locking element similar to a self-locking draw. Figure 8 During the spacer installation process, the steel needle is inserted into the blind hole on the spacer, and the spacer can be quickly installed by using the air cylinder and the steel needle to carry the spacer. The steel needle and the spacer do not interfere with the rectangular bundling steel belt during the forward movement of the steel needle and the spacer, and the effect of almost synchronous installation of the evaporator bundling and the spacer installation is achieved. In addition, the spacer is installed after the spacer is installed, which better ensures that the spacer can be smoothly and stably inserted into the spacer installation hole.
[0073] By adopting the present application, the edge plate of the evaporator core can be prevented from being damaged, and the spacer on the evaporator core can be quickly, stably and smoothly installed in place during the bundling of the evaporator core, without the need for separate additional workstations for manual installation of the spacer, thereby saving the labor for installing the spacer. By adopting the present application, the spacer on an evaporator core can be installed in an average of five seconds (this installation process mainly involves the direct insertion of the steel needle into the blind hole of the spacer and the pushing of the spacer to the corresponding position, that is, only one time of air cylinder action is required), which is high in efficiency and fundamentally avoids the inconvenience of spacer installation in the traditional way.
[0074] According to the scheme of the present application, the top edge of the rectangular banded steel strip is gripped by the strip-shaped suction cup, and the rectangular banded steel strip can be directly and smoothly sleeved on the evaporator core body by means of the air cylinder, and then the evaporator core body can be quickly banded only by two sets of clamping jaws and corresponding extenders, and the structure is simpler than that of the traditional scheme, and the occupied space can be reduced by nearly one third.
