Description

Technical Field

[0001] This utility model belongs to the field of air conditioning parts production equipment, specifically relating to a precision pre-installation device for air conditioning liquid receiver partitions. Background Technology

[0002] In the processing of air conditioning liquid receivers, pre-installing the internal partitions (or partitions) into the closed cylindrical blank is a key process. Usually, the liquid receiver blank with one end closed is fixed with its large opening facing upwards. Then, the material conveying mechanism transports the individual partitions to the pre-installation station. The pre-installation mechanism then uses a clamp to pick up the partitions and place them into the liquid receiver blank. Finally, the stamping mechanism presses them to the specified depth.

[0003] However, existing pre-assembly equipment has defects during operation: after the partition is conveyed by the conveying mechanism, it is very easy for the partition to flip over due to vibration and other reasons, that is, it is conveyed to the pre-assembly station with its bottom surface facing up; the pre-assembly fixture of the existing equipment will indiscriminately clamp the reversed partition and directly install it into the liquid reservoir; this reverse installation is a serious assembly error, which will cause the entire workpiece to be unqualified, directly causing waste of materials and time, increasing production costs, and restricting the improvement of production yield.

[0004] Therefore, there is an urgent need in this field for a pre-installation device that can correct the direction of the partition and achieve precise pre-installation, so as to avoid the problem of workpiece scrap caused by reverse installation of the partition. Utility Model Content

[0005] To solve the above problems, this utility model proposes a precise pre-installation device for air conditioner liquid receiver partitions. The pre-installation device of this utility model will automatically detect the positive and negative states of the partitions, and at the same time, the clamp of the pre-installation mechanism will rotate the reversed partitions to the positive state and install them into the liquid receiver blank, thus avoiding the scrapping of the workpiece.

[0006] The specific solution is as follows: a precise pre-installation device for air conditioning liquid receiver partitions, including a material conveying mechanism, a pre-installation mechanism and a control unit, wherein the material conveying mechanism extends to the pre-installation mechanism to convey partitions to the pre-installation mechanism; The pre-assembly mechanism is equipped with a vision sensor for detecting the orientation of the partition. The pre-assembly mechanism is also equipped with a flipping clamp. Both the vision sensor and the flipping clamp are connected to the control unit. The control unit controls the flipping clamp to hold the partition upright and place it into the reservoir based on the feedback from the vision sensor.

[0007] Preferably, the flipping fixture includes two opposing jaws and a fixture base. The jaws include an inner jaw and an outer jaw. The outer jaw is fixed to the fixture base and a rotary motor is fixed to the outer jaw. The rotary motor is connected to the inner jaw.

[0008] When the conveying mechanism delivers the partition in the reversed state to the pre-assembly mechanism, the vision sensor detects that the partition is in the reversed state. At this time, the flipping fixture picks up the partition and flips the inner jaws to change the partition to the forward state and install it in the liquid reservoir.

[0009] Preferably, the pre-installation mechanism further includes a drive unit connected to a flipping fixture. The drive unit includes a first drive member to drive the flipping fixture to move horizontally toward the liquid reservoir; and a second drive member to drive the flipping fixture to move vertically toward the liquid reservoir.

[0010] The first driving component includes a fixed seat and a movable seat, which are connected to form a horizontally arranged first sliding track. A first hydraulic telescopic rod is fixed to the fixed seat and connected to the movable seat. The first hydraulic telescopic rod can drive the movable seat to slide along the first sliding track. The second driving component includes a connecting seat, which is connected to the movable seat to form a vertically arranged second sliding track. A second hydraulic telescopic rod is fixed to the movable seat and connected to the connecting seat. The second hydraulic telescopic rod can drive the connecting seat to slide along the second sliding track. A flipping clamp is fixed to the connecting seat. Preferably, it also includes a stamping mechanism, which is located close to the pre-assembly mechanism to contact and press down the diaphragm inside the reservoir.

[0011] Preferably, the stamping mechanism includes a hydraulic drive and a pressing component. The hydraulic drive is connected to one end of the pressing component and drives it to move up and down. The other end of the pressing component is provided with a rotary motor, which is connected to a pressing head. The pressing head is in contact with a partition.

[0012] Preferably, the pre-assembly mechanism is provided with an assembly table for placing the liquid reservoir during pre-assembly, and the stamping mechanism is provided with a stamping table for placing the liquid reservoir during stamping. The stamping table can be rotated and fixed, and the stamping table and the assembly table are located on the same straight line.

[0013] The pressing head rotates while pressing down, and the rotation drives the liquid reservoir to rotate synchronously. A polishing wheel is provided on the outside of the liquid reservoir to polish it.

[0014] Preferably, it also includes a transfer mechanism, the position of which matches the assembly table and the stamping table, for transferring the liquid reservoir from the assembly table to the stamping table. The transfer mechanism is located next to the assembly table and the stamping table and is used to clamp the liquid reservoir for transferring it.

[0015] Preferably, the transfer mechanism includes a clamping assembly, which is connected to a translation unit and a lifting unit. The translation unit drives the clamping assembly to move along the line connecting the assembly table and the stamping table; the lifting unit drives the clamping assembly to move up and down in the vertical direction.

[0016] The clamping assembly includes multiple electric clamps to hold and fix the liquid reservoir. The lifting unit is hydraulic, which drives the clamping assembly to rise and detach the liquid reservoir from the assembly table. The translation unit consists of a slide rail and a drive motor, which moves the clamping assembly from the assembly table to the stamping table. The lifting unit then drives the clamping assembly to fall and detach the liquid reservoir from the stamping table. The clamping assembly reciprocates to transport multiple liquid reservoirs.

[0017] Preferably, the material conveying mechanism includes a feeding component and a conveying component. The feeding component is connected to the hopper, and one end of the conveying component is connected to the feeding component while the other end extends to the bottom of the pre-assembly mechanism. The feeding component transports the partition to the conveying component, and the conveying component conveys it to the pre-assembly mechanism.

[0018] Preferably, multiple pre-installed devices are connected in parallel, and the transfer mechanism drives the liquid storage tank to move between the pre-installed devices.

[0019] Since a liquid reservoir needs to be pre-installed with multiple diaphragms, multiple devices are required to work together, and a single transfer mechanism is needed to transfer the liquid synchronously. The beneficial effects of this utility model are as follows: (1) This utility model realizes automatic detection and correction of the direction of the partition, eliminating the core quality defect of the existing equipment that causes the workpiece to be scrapped due to reverse installation; by introducing a vision sensor and control unit, the direction of each partition can be judged in real time and accurately. Once a reverse partition is detected, the flipping fixture will immediately perform the flipping action, fundamentally avoiding the problem of workpiece scrapping caused by this.

[0020] (2) This utility model constructs a fully automated operation system, which greatly improves production efficiency and process consistency and reduces reliance on manpower; the pre-assembly mechanism and the stamping mechanism are integrated by the transfer mechanism to realize full-process mechanization. This not only frees operators from repetitive and tiring work, but more importantly, it ensures that the pre-assembly process of each liquid reservoir follows absolutely consistent process parameters, eliminates quality fluctuations caused by human factors, and achieves stable high-quality production.

[0021] (3) This utility model provides a special layout design for multiple pre-installed equipment to be connected in parallel and coordinated by a central transfer mechanism, which is aimed at the actual production needs of a liquid storage tank that requires the installation of multiple partitions. This makes the production line more adaptable and reasonable, not only breaking through the efficiency bottleneck of multiple pre-installation at a single workstation, but also making the production line more flexible and improving the flexibility of adjustment.

Detailed Implementation

[0024] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0025] In the description of this application, it should be understood that the terms indicating connection relationships should be interpreted broadly. In this application, the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0026] Example 1 like Figure 1-5 As shown, an air conditioner liquid receiver partition precision pre-assembly device includes a material conveying mechanism 3, a pre-assembly mechanism 1, a stamping mechanism 2, a transfer mechanism 4, and a control unit. The material conveying mechanism 3 extends to the pre-assembly mechanism 1 to convey the partition to the pre-assembly mechanism 1. The pre-assembly mechanism 1 is equipped with a vision sensor for detecting the orientation of the partition. The pre-assembly mechanism 1 is also equipped with a flip clamp 12. Both the vision sensor and the flip clamp 12 are connected to the control unit. The control unit controls the flip clamp 12 to hold the partition in the correct orientation and place it into the liquid reservoir based on the feedback from the vision sensor.

[0027] The flipping fixture 12 includes two opposing grippers 122 and a fixture base 121. The grippers 122 include an inner gripper and an outer gripper 1222. The outer gripper 1222 is fixed to the fixture base 121. A rotating motor 1223 is fixed to the outer gripper 1222. The rotating motor 1223 is connected to the inner gripper 1221.

[0028] When the feeding mechanism 3 conveys the partition in the reverse state to the pre-assembly mechanism 1, the vision sensor detects that the partition is in the reverse state. At this time, the flipping clamp 12 picks up the partition and the inner jaw 1221 flips it so that the partition is in the forward state and installed in the liquid reservoir.

[0029] The pre-installation mechanism 1 also includes a drive unit 13, which is connected to the flipping clamp 12. The drive unit 13 includes a first drive member 131 to drive the flipping clamp 12 to move horizontally toward the liquid reservoir; and a second drive member 132 to drive the flipping clamp 12 to move vertically toward the liquid reservoir.

[0030] The first driving component 131 includes a fixed seat and a movable seat, which are connected to form a horizontally arranged first sliding track. A first hydraulic telescopic rod is fixed to the fixed seat and connected to the movable seat. The first hydraulic telescopic rod can drive the movable seat to slide along the first sliding track. The second driving component 132 includes a connecting seat, which is connected to the movable seat to form a vertically arranged second sliding track. A second hydraulic telescopic rod is fixed to the movable seat and connected to the connecting seat. The second hydraulic telescopic rod can drive the connecting seat to slide along the second sliding track. The flipping clamp 12 is fixed to the connecting seat. The stamping mechanism 2 is positioned close to the pre-assembly mechanism 1 to contact and press down the partition inside the reservoir.

[0031] The stamping mechanism 2 includes a hydraulic drive 21 and a pressing component 22. The hydraulic drive 21 is connected to one end of the pressing component 22 and drives it to move up and down. The other end of the pressing component 22 is provided with a rotary motor 221. The rotary motor 221 is connected to a pressing head 222, and the pressing head 222 is in contact with a partition.

[0032] The pre-assembly mechanism 1 is provided with an assembly platform 11 for placing the liquid reservoir during pre-assembly, and the stamping mechanism 2 is provided with a stamping platform 23 for placing the liquid reservoir during stamping. The stamping platform 23 can be rotated and fixed, and the stamping platform 23 and the assembly platform 11 are located on the same straight line.

[0033] The pressing head 222 rotates while pressing down, and the liquid reservoir rotates synchronously during the rotation. A polishing wheel 24 is provided on the outside of the liquid reservoir to polish it.

[0034] The transfer mechanism 4 is positioned to match the assembly table 11 and the stamping table 23 for transferring the liquid reservoir from the assembly table 11 to the stamping table 23. The transfer mechanism 4 is located next to the assembly table 11 and the stamping table 23 for clamping the liquid reservoir and transferring it.

[0035] The transfer mechanism 4 includes a clamping assembly 41, which is connected to a translation unit 42 and a lifting unit 43. The translation unit 42 drives the clamping assembly 41 to move along the line connecting the assembly table 11 to the stamping table 23; the lifting unit 43 drives the clamping assembly 41 to move up and down in the vertical direction.

[0036] The clamping assembly 41 includes multiple electric clamps for clamping and fixing the liquid reservoir. The lifting unit 43 is a hydraulic lifting unit that raises the clamping assembly 41 to lift the liquid reservoir off the assembly table 11. The translation unit 42 consists of a slide rail and a drive motor that moves the clamping assembly 41 from the assembly table 11 to the stamping table 23. The lifting unit 43 then lowers the clamping assembly 41 to lower the liquid reservoir into the stamping table 23. The clamping assembly 41 reciprocates to transport multiple liquid reservoirs.

[0037] The material conveying mechanism 3 includes a feeding component 31 and a conveying component 32. The feeding component 31 is connected to the hopper, and one end of the conveying component 32 is connected to the feeding component 31 and the other end extends to the bottom of the pre-assembly mechanism 1. The feeding component 31 transports the partition to the conveying component 32, and the conveying component 32 conveys it to the pre-assembly mechanism 1.

[0038] Multiple pre-installed devices are connected in parallel, and the transfer mechanism 4 drives the liquid storage tank to move between the pre-installed devices.

[0039] Since a liquid reservoir needs to be pre-installed with multiple diaphragms, multiple devices are required to work together, and the transfer is carried out synchronously by a transfer mechanism 4. For example, three pre-installed devices are set up in parallel, and three partitions are pre-installed into the liquid storage tank in sequence. From left to right, they include the first assembly platform 11, the first stamping platform 23, the second assembly platform 11, the second stamping platform 23, the third assembly platform 11, and the third stamping platform 23; and also include a feeding port and a discharging port.

[0040] The transfer mechanism 4 is equipped with seven electric clamps, numbered from first to seventh from left to right. The first liquid reservoir is clamped by the first electric clamp at the feed point and placed on the first assembly table 11. After placement, the clamping assembly 41 resets, and the pre-assembly mechanism 1 pre-assembles the partition. After pre-assembly, the second electric clamp clamps the first liquid reservoir and moves it to the first stamping table 23. Simultaneously, the first electric clamp clamps a new second liquid reservoir and moves it into the first assembly table 11. This process is repeated until the first liquid reservoir moves to the third stamping table 23. At this time, all stations are working on workpieces, and the six stations are working simultaneously. After the third stamping table 23 finishes working, the seventh electric clamp clamps the first liquid reservoir and moves it to the discharge point. At the same time, the remaining electric clamps also clamp the remaining liquid reservoirs simultaneously. With each reciprocating motion of the clamping assembly 41, all liquid reservoirs move forward one step, realizing multi-station synchronous operation and improving work efficiency.
