Description

Technical Field

[0001] The utility model relates to the technical field of square tube processing, in particular to a square aluminum tube feeding device. Background Art

[0002] In the field of new energy vehicle technology, electric vehicles generally use power battery packs as a power source. Unlike fuel engines, electric vehicles do not have a power device that generates heat sources, and cannot provide heat sources to power battery packs. At the same time, they cannot provide the warm air heat source required for air conditioning, defrosting, etc. Therefore, electric vehicles must rely on electricity to use PTC heaters for heating.

[0003] PTC heaters usually use square aluminum tubes as the installation carrier of PTC heating elements. When square aluminum tubes are processed as heater accessories, conveying equipment is usually used to transport the aluminum tubes to the processing equipment for loading. However, when the aluminum tubes are transported on the conveying equipment, their position is easily offset, making it difficult to dock with the processing equipment, which slows down the processing efficiency.

[0004] Therefore, a square aluminum tube feeding device is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a square aluminum tube feeding device, which has the advantages of more accurate feeding position, etc., and solves the problem that the position of the aluminum tube is easily offset when it is transported on the conveying equipment and is not easy to connect with the processing equipment well.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a square aluminum tube feeding device, comprising a conveyor frame, on which a feeding conveying mechanism, a centering adjustment mechanism, and a clamping feeding mechanism are sequentially arranged;

[0007] The feed conveying mechanism comprises a pair of conveying rollers rotatably arranged on a conveying frame and capable of rotating autonomously;

[0008] The centering adjustment mechanism includes a position sensor fixed to the inner side of the conveyor frame, the conveyor frame is also rotatably provided with two pairs of positioning wheels, and the conveyor frame is also provided with two pairs of vacuum suction cups that can move linearly and correspond to the two pairs of positioning wheels;

[0009] The clamping and feeding mechanism comprises a pair of mounting plates with adjustable spacing, and a conveyor belt is provided on both mounting plates.

[0010] Furthermore, a driving motor is fixed on the conveyor frame, a driving wheel is fixed to the output shaft of the driving motor, driven wheels are fixed to the outer sides of the two conveying rollers, and transmission belts are sleeved on the outer sides of the driving wheel and the two driven wheels.

[0011] Furthermore, the conveyor frame is also provided with two pairs of positioning cylinders corresponding to the two pairs of positioning wheels, the output shafts of the positioning cylinders are fixed with L-shaped mounting frames, and the vacuum suction cups are mounted on the corresponding L-shaped mounting frames.

[0012] Furthermore, two conveying wheels are rotatably provided on the two mounting plates through a rotating shaft, the two conveying wheels on the same mounting plate are arranged on the inner side of the corresponding conveyor belt, and a conveying motor is fixed at the bottom of the two mounting plates, and the output shaft of the conveying motor is fixed to the corresponding conveying wheel.

[0013] Furthermore, two bidirectional cylinders are fixed on the conveyor frame, and output ends on both sides of the bidirectional cylinders are respectively fixed to two mounting plates.

[0014] Furthermore, a plurality of auxiliary rollers pressing on the inner side of the conveyor belt are rotatably provided on the mounting plate, and a plurality of supporting rollers are rotatably provided on the conveyor frame through a rotating shaft, and the supporting rollers are located below the conveyor belt.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] In the square aluminum tube feeding device, when the position sensor senses the head of the aluminum tube, the positioning cylinder pushes out, and the vacuum suction cup presses the aluminum tube against the positioning wheel, so that the aluminum tube can be adsorbed by the vacuum suction cup, and then the positioning cylinder is extended and retracted to preliminarily change the feeding position of the aluminum tube, so that the position of the aluminum tube is more centered, which makes it easier for the aluminum tube to enter between the two conveyor belts, and then the position of the aluminum tube is fine-tuned by clamping the two conveyor belts, so that the feeding position of the aluminum tube is more accurate;

[0018] At the same time, when the aluminum tube is sent between the two conveyor belts, the bottom surface is supported by the support roller. The output end of the rotary cylinder rotates, which can also drive the pressure roller to press the aluminum tube onto the support roller.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 A square aluminum tube feeding device in this embodiment includes a conveyor frame 1, on which a feeding conveying mechanism 2, a centering adjustment mechanism 3, and a clamping feeding mechanism 4 are sequentially arranged. The square aluminum tube is fed to the conveyor frame 1 through the feeding conveying mechanism 2, and after being fed for a certain distance, it is preliminarily center-adjusted through the centering adjustment mechanism 3, and then the aluminum tube is fed to the processing equipment for processing through the clamping feeding mechanism 4.

[0027] The aluminum tube is initially introduced through the feed conveying mechanism 2, such as Figure 2 As shown, the feeding conveying mechanism 2 includes a pair of conveying rollers 201 which are rotatably arranged on the conveying frame 1 through a rotating shaft. The aluminum tube can be fed through the rotating conveying rollers 201. A driving motor 202 is fixed on the conveying frame 1. A driving wheel 203 is fixed to the output shaft of the driving motor 202. Driven wheels 204 are fixed to the outer sides of the two conveying rollers 201. The outer sides of the driving wheel 203 and the two driven wheels 204 are covered with a transmission belt 205.

[0028] The output shaft of the driving motor 202 drives the outer driving wheel 203 to rotate. Under the transmission action of the transmission belt 205, the driven wheel 204 can drive the conveying roller 201 to rotate, and the aluminum tube is conveyed through the conveying roller 201.

[0029] After the aluminum tube is transported to a certain distance, the centering adjustment mechanism 3 can be used to perform preliminary centering adjustment, so that the aluminum tube can be accurately centered through the clamping feeding mechanism 4, making the feeding position of the aluminum tube more accurate. Figure 3 As shown, the centering adjustment mechanism 3 includes a position sensor 301 fixed on the inner side of the conveyor frame 1, and two pairs of positioning wheels 302 are also provided on the conveyor frame 1 through the rotation of the rotating shaft. The conveyor frame 1 is also provided with two pairs of positioning cylinders 303 corresponding to the two pairs of positioning wheels 302, and the output shaft of the positioning cylinder 303 is fixed with an L-shaped mounting frame 304, and a pair of vacuum suction cups 305 are installed on the L-shaped mounting frame 304.

[0030] The position sensor 301 is arranged at the entrance of the clamping feeding mechanism 4. When the position sensor 301 senses the head of the aluminum tube, the positioning cylinder 303 is pushed out, and the vacuum suction cup 305 presses the aluminum tube against the positioning wheel 302. The aluminum tube can be adsorbed by the vacuum suction cup 305, and then the positioning cylinder 303 is extended and retracted to preliminarily change the feeding position of the aluminum tube so that the aluminum tube is centered.

[0031] After the position of the aluminum tube is fine-tuned, it is more convenient to enter the clamping and feeding mechanism 4 for precise centering. Figure 4-5 As shown, the clamping feeding mechanism 4 includes a pair of mounting plates 401, two conveying wheels 402 are provided on the two mounting plates 401 through rotation of a rotating shaft, a conveying belt 403 is commonly sleeved on the two conveying wheels 402 on the same mounting plate 401, a conveying motor 404 is fixed to the bottom of the two mounting plates 401, the output shaft of the conveying motor 404 is fixed to the corresponding conveying wheel 402, and a plurality of auxiliary rollers 405 pressed on the inner side of the conveying belt 403 are provided on the mounting plate 401 through rotation of a rotating shaft. The corresponding conveying wheel 402 can be driven to rotate by the output shaft of the conveying motor 404, and the aluminum tube is arranged between the two conveying belts 403, so that the aluminum tube can be conveyed.

[0032] The distance between the two mounting plates 401 is adjustable. When the aluminum tube is sent between the two conveyor belts 403, the two conveyor belts 403 can be clamped to adjust the position of the aluminum tube to the center, which is convenient for subsequent processing equipment to perform precise processing. Two two-way cylinders 406 are fixed on the conveyor frame 1. The output ends on both sides of the two-way cylinder 406 are respectively fixed to the two mounting plates 401. The two ends of the two-way cylinder 406 are pushed out, and the distance between the two mounting plates 401 becomes larger. The two ends of the two-way cylinder 406 are retracted, and the distance between the two mounting plates 401 becomes smaller. The distance between the two conveyor belts 403 can be flexibly adjusted according to the size of the aluminum tube.

[0033] In order to improve the stability of the aluminum tube during transportation, a plurality of support rollers 407 are provided on the conveyor frame 1 through rotation of a rotating shaft, and the support rollers 407 are located below the conveyor belt 403. A pair of rotating cylinders 408 are also fixed on the conveyor frame 1, and rotating arms 409 are fixed at the output ends of the two rotating cylinders 408. A pressure roller 410 is provided between the two rotating arms 409 through rotation of a rotating shaft. When the aluminum tube is sent between the two conveyor belts 403, the bottom surface is supported by the support rollers 407. The output end of the rotating cylinder 408 rotates, which can also drive the pressure rollers 410 to press the aluminum tube onto the support rollers 407. The two sides of the aluminum tube are in close contact with the corresponding conveyor belts 403 respectively, so that the conveyor belt 403 can be used to drive the aluminum tube to transport and feed.

[0034] By adopting the above-mentioned square aluminum tube feeding device, the feeding position of the aluminum tube can be accurately adjusted, which is convenient for accurate docking with subsequent processing equipment and improving processing accuracy. The specific feeding method is as follows:

[0035] The output shaft of the driving motor 202 drives the outer driving wheel 203 to rotate. Under the transmission action of the transmission belt 205, the driven wheel 204 can drive the conveying roller 201 to rotate, and the aluminum tube is conveyed through the conveying roller 201. When the position sensor 301 senses the head of the aluminum tube, the positioning cylinder 303 is pushed out, and the vacuum suction cup 305 presses the aluminum tube against the positioning wheel 302, and the aluminum tube can be adsorbed by the vacuum suction cup 305. Then, the positioning cylinder 303 is stretched and retracted to initially change the position of the aluminum tube. The feeding position of the aluminum tube is such that the aluminum tube is centered and then directly sent to between the two conveyor belts 403. The two ends of the two-way cylinder 406 retract, and the distance between the two mounting plates 401 becomes smaller. The two conveyor belts 403 are close to the two sides of the aluminum tube, and the feeding position of the aluminum tube is further fine-tuned to the middle. At the same time, the output end of the rotating cylinder 408 rotates, and it can also drive the pressing roller 410 to press the aluminum tube onto the supporting roller 407, so that the aluminum tube can be accurately sent to the processing equipment through the conveyor belt 403 for precise processing.
