Description

Technical Field

[0001] This invention relates to the field of float assembly technology, and more specifically to an automatic float assembly device. Background Technology

[0002] Float-type liquid level sensors are widely used in liquid level detection and control in industrial storage tanks, home appliances, and automotive oil reservoirs due to their simple structure, reliable operation, and low cost. Their core structure consists of a guide rod, a float, and a limiting clamp. The clamp is embedded in an annular groove on the outer wall of the guide rod to limit the vertical movement of the float, thereby determining the liquid level measurement range and high / low alarm points. The assembly accuracy and installation reliability of the clamp directly determine the sensor's measurement accuracy and service life.

[0003] Currently, the assembly of floats and clamps in the industry is mostly done manually with simple tooling: operators first manually slip the float onto the guide rod, and then use snap ring pliers to expand the elastic clamps one by one and then snap them into the corresponding slots. This assembly method has many unavoidable drawbacks: First, the assembly efficiency is low. A single guide rod needs to complete the assembly of multiple sets of clamps and floats in sequence. Manual operation is time-consuming and has low capacity, making it difficult to meet the needs of large-scale production. Moreover, the assembly consistency is poor. Manual operation is prone to problems such as excessive expansion of clamps causing plastic deformation, clamps not being fully inserted into the tank bottom, and local warping. After long-term use, clamps are prone to falling off and float jamming. At the same time, the position of the slots depends on manual visual alignment, and the positioning accuracy is greatly affected by the experience of the personnel, which can easily lead to the deviation of the liquid level range and alarm point, making it difficult to guarantee the product yield.

[0004] In response to the shortcomings of manual assembly, some automated assembly equipment has emerged in the industry. However, existing equipment generally has functional limitations: most equipment can only be adapted to single-specification single float sensors and cannot be compatible with multi-float products of different lengths and different numbers of slots, resulting in poor equipment flexibility; moreover, most lack automatic slot position detection function and only assemble according to preset fixed coordinates, which cannot offset the slot position deviation caused by the guide rod machining tolerance, and is prone to problems such as misalignment of clamp assembly and jamming of guide rod. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic float assembly device to solve the above problems.

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

[0007] An automatic float assembly device includes an assembly table, a float feeding line is provided on the right side of the assembly table, and a swing receiving component, a test frame, a clamp installation component and a clamp feeding component are installed on the top of the assembly table.

[0008] The test frame is located on the front of the swing receiving component, the clamp mounting component is located on the back of the swing receiving component, the clamp feeding component is located on the left side of the clamp mounting component, the test frame is equipped with a lifting and lowering slot measuring component, the top of the test frame is equipped with a float feeding component, the float feeding component is located directly above the swing receiving component, and the left side of the swing receiving component is equipped with a feeding hopper.

[0009] The float feeding line horizontally transports the float to the right side of the swing receiving assembly and pushes the float into the swing receiving assembly. The swing receiving assembly then raises the float. The slot positioning assembly detects the slot position on the float. The clamp installation assembly receives the clamps from the clamp feeding assembly and sequentially inserts the clamps into the slots according to the detected position. At the same time, the float feeding assembly sequentially attaches the floats to the float.

[0010] Furthermore, the surface of the conveyor belt of the float feeding line is provided with several grooves, the cross-section of the grooves is semi-circular, and baffles are provided on both sides of the float feeding line. There is a gap between the left baffle and the conveyor belt. A feeding notch is provided at the front end of the left baffle, and a top material cylinder is installed at the front end of the right baffle. The top material cylinder can push the float from the feeding notch into the swing receiving assembly.

[0011] Furthermore, the swing receiving assembly includes a bracket installed on the top of the assembly table, a swing seat rotatably mounted inside the bracket, a swing motor installed on the outside of the bracket, the output end of the swing motor being connected to the swing seat, and a receiving cylinder adapted to the float being installed on the top of the swing seat, the float being able to be inserted into the receiving cylinder.

[0012] Furthermore, the top of the swing base is provided with mounting bolts, and the receiving cylinder is threadedly connected to the mounting bolts.

[0013] Furthermore, a lifting screw is installed inside the test frame, and a slide groove is opened inside the test frame. A laser displacement sensor is installed at the top of the slide groove. The slot positioning assembly includes a slide frame slidably connected in the slide groove. A nut block is provided at the rear end of the slide frame. The nut block is threadedly connected to the lifting screw. A telescopic cylinder is installed at the front end of the slide frame. A pressure sensor is fixedly installed at the telescopic end of the telescopic cylinder. A test sleeve is installed on the pressure sensor.

[0014] Furthermore, the test sleeve is elliptical in shape and the opening is curved outwards.

[0015] Furthermore, the float feeding assembly includes a float sleeve installed on the top of the test frame, with floats stacked in the float sleeve. A top clamp cylinder and a material blocking cylinder are installed on the outside of the float sleeve. The material blocking cylinder can block the bottom float, and the top clamp cylinder can clamp the second float below.

[0016] Furthermore, the clamp installation assembly includes a turntable rotatably mounted on the top of the assembly table. Several lifting screws and guide columns are mounted on the top of the turntable. Several lifting seats are provided between the lifting screws and guide columns. One side of the lifting seat has a guide hole, and the other side has a threaded hole. The corresponding lifting screws are threaded into the corresponding threaded holes, and the corresponding guide columns pass through the corresponding guide holes. A telescopic cylinder is mounted on the top of the lifting seat. A clamp receiving component is mounted on the telescopic end of the telescopic cylinder. The clamp receiving component is semi-circular and has a slot on its inner wall, so that the clamp can be tightly inserted into the slot.

[0017] Furthermore, the clamp feeding assembly includes a support frame and a clamp sleeve fixedly installed on the top of the assembly table. The support frame is located on the left side of the clamp sleeve. Several telescopic cylinders are installed inside the support frame. A top piece is fixedly installed on the telescopic end of the telescopic cylinder. The cross-section of the clamp sleeve is set in the same shape as the clamp. Several top grooves are opened on the left side of the clamp sleeve, and several guide ports are opened on the right side of the clamp sleeve. The top grooves and guide ports are set in a corresponding manner, and the top piece can pass through the top grooves and guide ports.

[0018] Furthermore, when the lifting seats and telescopic cylinders are brought together, their thickness is an integer multiple of the clamp thickness, and the clamp receiving parts and the guide ports can correspond one-to-one.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention, through the modular and collaborative layout of the float feeding line, the swing receiving component, the slot measuring component, the clamp installation component, the float feeding component, and the unloading hopper, can automatically complete the entire process of horizontal float feeding, attitude flipping, slot position detection, graded clamp installation, float assembly, and automatic unloading of finished products. The entire process requires no manual intervention, improving efficiency several times compared to manual assembly, meeting the needs of large-scale mass production, and the overall layout of the equipment is compact with high space utilization.

[0021] 2. This invention employs a pressure-sensitive elastic testing sleeve in conjunction with a lifting drive and laser displacement detection. It can slide down the outer wall of the float and automatically identify the slot position and accurately record the coordinates through sudden changes in resistance. There is no need to pre-set fixed assembly points, which can effectively accommodate slot position deviations caused by guide rod machining tolerances, ensuring that the sleeve is accurately embedded in the bottom of the slot and avoiding assembly misalignment problems from the root. At the same time, the testing sleeve can simultaneously scrape off burrs, debris and impurities from the slot and float surface during the testing process, which also has a cleaning function, preventing residual impurities from causing the float to slide and jam, thus improving the reliability of product operation.

[0022] 3. The clamp installation component of this invention adopts multiple independently controlled lifting seats and telescopic cylinders, combined with the multi-station top material structure of the clamp feeding component, which can complete the synchronous feeding of multiple clamps at one time. The assembly height of each clamp is adjusted according to the detected clamp slot position, and the clamp installation and float connection are completed from bottom to top. It can automatically adapt to the assembly requirements of single float, double float and even multi-slot multi-float, and can complete product changeover without changing the core tooling. The flexibility and versatility of the equipment are significantly improved. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1, as Figures 1-9 As shown, an automatic float assembly device includes an assembly platform 1, a float feeding line 2 is provided on the right side of the assembly platform 1, and an oscillating receiving component 3, a test frame 4, a clamp installation component 7 and a clamp feeding component 8 are installed on the top of the assembly platform 1.

[0035] The test frame 4 is located on the front of the swing receiving component 3, the clamp mounting component 7 is located on the back of the swing receiving component 3, the clamp feeding component 8 is located on the left side of the clamp mounting component 7, the test frame 4 is equipped with a lifting and lowering slot measuring component 5, the top of the test frame 4 is equipped with a float feeding component 6, the float feeding component 6 is located directly above the swing receiving component 3, and the left side of the swing receiving component 3 is equipped with a discharge hopper 9.

[0036] The float feeding line 2 horizontally transports the float to the right side of the swing receiving assembly 3 and pushes the float into the swing receiving assembly 3. The swing receiving assembly 3 then raises the float. The slot measuring assembly 5 detects the slot position on the float. The clamp installation assembly 7 receives the clamps from the clamp feeding assembly 8 and sequentially inserts the clamps into the slots according to the detected position. At the same time, the float feeding assembly 6 sequentially attaches the floats to the float.

[0037] Assembly steps: The float is placed horizontally on the float loading line 2 (manual or robotic loading). The float loading line 2 horizontally transports the float to the right side of the swing receiving assembly 3, then pushes the float into the swing receiving assembly 3. The swing receiving assembly 3 drives the float to swing to a vertical position. The slot positioning assembly 5 descends from top to bottom along the surface of the float (the friction with the surface of the float provides downward pressure, correcting the float's position and improving assembly accuracy). When the slot positioning assembly 5 moves to the slot position, the slot is positioned... The sudden increase in the descent resistance of the slot positioning component 5 allows for the determination of the slot position. Simultaneously, it also preliminarily cleans the outer surfaces of the slot and float, preventing impurities from affecting subsequent assembly. Then, the clamp installation component 7 rotates to the clamp feeding component 8 to receive the clamps from it. The clamp installation component 7 rotates back, inserting the clamps sequentially into the corresponding slots from bottom to top. Once the lowest clamp is inserted, the float feeding component 6 lowers the float, which then fits onto the float rod. This single insertion and fitting completes the automatic assembly of the float. After assembly, the swing receiving component 3 swings to the left, causing the assembled float and float rod to tilt downwards. The assembled float and float rod fall into the discharge hopper 9 and automatically slide down under gravity. A hopper or conveyor line can be installed below the discharge hopper 9; no specific limitations are imposed in this invention.

[0038] In practical use, there are single float assembly and double float assembly, etc. This invention can automatically control the number of floats assembled according to the number of slots on the float rod, and has a wide range of applications.

[0039] In embodiment two, based on the above embodiment, the float feeding line 2 is further provided with a plurality of grooves 21 on the surface of the conveyor belt. The cross-section of the grooves 21 is semi-circular. Both sides of the float feeding line 2 are provided with baffles 22. There is a gap between the left baffle 22 and the conveyor belt. The front end of the left baffle 22 is provided with a feeding notch 23. The front end of the right baffle 22 is provided with a top-loading cylinder 24. The top-loading cylinder 24 can push the float from the feeding notch 23 into the swing receiving assembly 3.

[0040] The oscillating receiving assembly 3 includes a bracket 31 mounted on the top of the assembly table 1. A swing base 32 is rotatably mounted inside the bracket 31. An oscillating motor 33 is mounted on the outside of the bracket 31, and the output end of the oscillating motor 33 is connected to the swing base 32. A receiving cylinder 35 adapted to a float is mounted on the top of the swing base 32, and the float can be inserted into the receiving cylinder 35. A mounting bolt 34 is provided on the top of the swing base 32, and the receiving cylinder 35 is threaded onto the mounting bolt 34.

[0041] Feeding: The float is placed horizontally in the groove 21, and the protrusion on the float is located in the gap between the left baffle 22 and the conveyor belt. The float is located between the two baffles 22. When the float is conveyed to the feeding gap 23, the top cylinder 24 can push the float from the feeding gap 23 into the receiving cylinder 35. Then the swing motor 33 drives the swing seat 32 to rotate 90 degrees to the left. The swing seat 32 drives the float to swing vertically upward through the receiving cylinder 35 to complete the feeding.

[0042] Example 3, based on the above examples, further includes: a lifting screw 41 installed inside the test frame 4; a sliding groove opened inside the test frame 4; a laser displacement sensor 42 installed at the top of the inner side of the sliding groove; a slot positioning assembly 5 including a slide 51 slidably connected in the sliding groove; a nut block 52 provided at the rear end of the slide 51; the nut block 52 being threadedly connected to the lifting screw 41; a telescopic cylinder 53 installed at the front end of the slide 51; a pressure sensor 54 fixedly installed at the telescopic end of the telescopic cylinder 53; and a test sleeve 55 installed on the pressure sensor 54.

[0043] The test sleeve 55 is elliptical in shape with its opening curved outwards. This provides better coverage and is suitable for testing floats of different radii.

[0044] Slot position detection: After the float swings to a vertical position, the telescopic cylinder 53 drives the test sleeve 55 to approach the float, opening it through the opening so that the test sleeve 55 is clamped onto the float. Then, the lifting screw 41 (driven by a motor) rotates, and the lifting screw 41 drives the slide 51 to descend through the nut block 52. The slide 51 drives the test sleeve 55 to descend along the outer surface of the float. When the test sleeve 55 moves to the slot position, it is embedded in the slot under its own elastic force. As the slide 51 continues to descend, the resistance on the test sleeve 55 increases sharply. The control system outside the equipment records this position, and the laser displacement sensor 42 detects the descending position information of the slide 51 in real time. The test sleeve 55 also scrapes against the slot.

[0045] Example 4, based on the above examples, further includes a float feeding assembly 6 including a float sleeve 61 installed on the top of the test frame 4, with floats stacked in the float sleeve 61, and a top clamping cylinder 62 and a material blocking cylinder 63 installed on the outside of the float sleeve 61. The material blocking cylinder 63 can block the bottom float, and the top clamping cylinder 62 can clamp the second float below.

[0046] When the lowest clamp is inserted into the slot, the material-stopping cylinder 63 retracts, and the lowest float descends under the action of gravity and is sleeved on the float rod. The second float is clamped by the top clamping cylinder 62. After the material is dropped, the material-stopping cylinder 63 extends, and the top clamping cylinder 62 releases the second float, which falls onto the material-stopping cylinder 63, thus achieving stable and continuous single material dropping.

[0047] Example 5, based on the above examples, further includes a clamp installation assembly 7 comprising a turntable 71 rotatably mounted on the top of the assembly table 1. The top of the turntable 71 is equipped with several lifting screws 72 and guide posts 73. Several lifting seats 74 are provided between the lifting screws 72 and guide posts 73. One side of each lifting seat 74 has a guide hole, and the other side has a threaded hole. The corresponding lifting screws 72 are threaded into the corresponding threaded holes, and the corresponding guide posts 73 pass through the corresponding guide holes. A telescopic cylinder 75 is mounted on the top of the lifting seat 74. A clamp receiving component 76 is mounted on the telescopic end of the telescopic cylinder 75. The clamp receiving component 76 is semi-circular in shape, and its inner wall has a slot, allowing the clamp to be tightly inserted into the slot.

[0048] The clamp feeding assembly 8 includes a support frame 81 and a clamp sleeve 84 fixedly installed on the top of the assembly table 1. The support frame 81 is located on the left side of the clamp sleeve 84. Several telescopic cylinders 82 are installed inside the support frame 81. A top piece 83 is fixedly installed on the telescopic end of the telescopic cylinders 82. The cross-section of the clamp sleeve 84 is set in the same shape as the clamp. Several top grooves 85 are opened on the left side of the clamp sleeve 84, and several guide ports 86 are opened on the right side of the clamp sleeve 84. The top grooves 85 and the guide ports 86 are set in a corresponding manner. The top piece 83 can pass through the top grooves 85 and the guide ports 86.

[0049] When several lifting seats 74 and telescopic cylinder 2 75 are brought together, their thickness is an integer multiple of the clamp thickness, and several clamp receiving parts 76 and several guide ports 86 can correspond one-to-one.

[0050] In this embodiment, taking a double float as an example, four sets of lifting screws 72 and guide columns 73 are set first. The four sets of lifting screws 72 are controlled to make the four sets of lifting seats 74 and telescopic cylinders 75 close together and be located at the top. The turntable 71 drives the clamp receiving part 76 to rotate to face the guide port 86 and correspond to the position of the guide port 86. The telescopic cylinder 82 drives the top part 83 to extend. The top part 83 can just be inserted into the clamp from the opening of the clamp. Then the top part 83 pushes the clamp into the guide port 86 and then inserts it into the clamp receiving part 76 to complete the clamp feeding.

[0051] Then, turntable 71 drives clamp receiving component 76 to rotate towards the float. Then, according to the recorded slot position, the four sets of lifting screws 72 are controlled to move the four sets of lifting seats 74 and telescopic cylinders 75 to the corresponding height. The lowest telescopic cylinder 75 drives clamp receiving component 76 to approach the float. Clamp receiving component 76 drives the clamp to insert into the slot. Then, the blocking cylinder 63 retracts. The lowest float descends under the action of gravity and is sleeved on the float. The second float is clamped by the top clamp cylinder 62. After the material is dropped, the blocking cylinder 63 extends and the top clamp cylinder 62 releases the second float. The second float falls on the blocking cylinder 63. At this time, the second and third telescopic cylinders 75 drive clamp receiving component 76 to approach the float. Clamp receiving component 76 drives the clamp to insert into the slot. Then, another float is lowered. After lowering, the last clamp is sleeved, completing the float assembly.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
