Description

Technical Field

[0001] The present invention relates to the technical field of volleyball production equipment, and in particular to a device and method for detecting air leakage positions in volleyball production. Background Art

[0002] In the volleyball production process, the airtightness detector is one of the important equipment to ensure product quality. It can help manufacturers to find air leakage problems in time, take corresponding measures to repair them, and improve the product qualification rate.

[0003] In the prior art, there is a ball production air leakage position detection device with a publication number of "CN221147972U", which belongs to the technical field of football leakage detection. A positioning plate is provided on the top of the cabinet, and ten groups of grooves are provided on the positioning plate, which can hold ten footballs or basketballs at one time. An air compressor is fixedly provided on the inner bottom surface of the cabinet, and the air outlet of the air compressor is connected to the four-way pipe through a rubber air pipe. The four-way pipe can connect four groups of rubber air pipes with ball needles at one time. The air compressor is connected to the control switch through a power cord, and the control switch is connected to the external 220V AC power through the power cord. A water basin is fixed on the outer side of the cabinet by screws, and a football or basketball is put into the water basin and manually rotated to observe the air leakage condition. A drain valve is provided at the bottom of the water basin to empty the sewage in the water basin; four groups of symmetrical moving wheels are provided at the bottom of the cabinet to facilitate the mobile position, which is specially used to detect the air leakage condition of footballs or basketballs. The air leakage position is marked with a red marker pen, and it is operated by one person with high operating efficiency, and the water in the water basin is replaced regularly.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] Some existing testing equipment may not have a convenient lifting device. In the process of putting the volleyball into the testing liquid and taking it out, manual operation is required, which is not only time-consuming and laborious, but also difficult to operate, and may easily cause unnecessary damage to the volleyball.

[0006] Existing detection technologies may have a low degree of automation and require a lot of manual intervention. There is no automatic stirring function for the test liquid, and manual stirring is required, which not only increases the labor intensity, but also makes it difficult to ensure the uniformity of stirring, affecting the stability and reliability of the test;

[0007] Traditional testing equipment may not have a dedicated cleaning device after the test is completed, and the test liquid remaining on the surface of the volleyball needs to be cleaned manually, which is not only troublesome, but may not be cleaned thoroughly, affecting the subsequent processing and use of the volleyball.

[0033] Place the volleyball to be tested on the ball support ring, start the clamping hydraulic cylinder, extend its movable end, and cooperate with the ball support ring to clamp the volleyball to be tested;

[0034] S3: Immerse in the test pool,

[0035] Start the lifting hydraulic cylinder to retract, drive the ball support ring and the clamping hydraulic cylinder to descend synchronously through the lifting fixed plate, and immerse the volleyball in the detection pool;

[0037] When the volleyball is immersed in the detection pool, the waterproof driving motor is started, and the clamping ball is driven to rotate through the meshing of the driving bevel gear and the driven bevel gear. The clamping ball rotates and fits with the volleyball, driving the volleyball to rotate on the supporting ball, so that the volleyball is fully in contact with the liquid in the detection pool;

[0044] 1. The setting of the stirring rod and the exhaust pipe enables the detection liquid to fully contact the surface of the volleyball. During the lifting process of the lifting hydraulic cylinder, the stirring plate on the stirring rod rotates through the transmission of the rack and the driven gear to stir the detection liquid and increase the fluidity of the detection liquid. At the same time, the gas discharged from the exhaust pipe further enhances the fluidity of the detection liquid, ensuring that the detection liquid can evenly contact all parts of the volleyball. When there is a leak in the volleyball, the leaked gas can react with the soapy water more quickly and more obviously to produce bubbles, greatly improving the accuracy of the detection.

[0045] 2. The clamping ball in the clamping ball seat and the supporting ball on the ball support ring work together to make the volleyball rotate in the test liquid under the drive of the waterproof drive motor. This allows every surface of the volleyball to have a chance to contact the test liquid, avoiding detection blind spots and further improving the accuracy of leak location detection.

[0046] 3. The setting of the lifting hydraulic cylinder allows the volleyball to be easily immersed in and out of the detection tank. The operator only needs to control the contraction and extension of the lifting hydraulic cylinder to easily complete the volleyball detection process. The operation is simple and quick.

[0047] 4. The coordination of the adjusting guide rod and the adjusting rod clamp enables the operator to adjust the position of the ball support ring in the detection pool according to actual needs, adapt to the detection of volleyballs of different sizes, and increase the flexibility and applicability of the equipment.

[0048] 5. The cooperation of waterproof drive motor, lifting hydraulic cylinder and other components realizes partial automation of the detection process. The waterproof drive motor automatically drives the volleyball to rotate, without manual operation, which improves the detection efficiency.

[0049] 6. The arrangement of the cleaning telescopic cylinder, arc-shaped cleaning plate and cleaning sponge on the transverse support rod enables the cleaning liquid on the surface of the volleyball to be cleaned in time after the inspection is completed. Start the cleaning telescopic cylinder and the waterproof drive motor, the waterproof drive motor drives the volleyball to rotate, and the cleaning telescopic cylinder drives the cleaning sponge to fit the volleyball, quickly and effectively cleaning the surface of the volleyball, which provides convenience for subsequent processing or repair work.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See also Figure 1-7 , the present invention provides a technical solution:

[0060] A device for detecting air leakage in the production of volleyballs. The device mainly consists of a sturdy bracket 1 as a basic supporting structure. A number of important components are fixedly installed at specific positions of the bracket 1 by means of screw fastening. Among them, the controller 2 is firmly fixed on the bracket 1 to accurately control the operation of each component. The detection pool 3 is also stably fixed on the bracket 1, providing the necessary space for air leakage detection of the volleyball. The detection pool 3 contains soapy water as the detection liquid. When there is a leak in the volleyball, the leaked gas will come into contact with the soapy water to produce bubbles.

[0061] At the position where the bracket 1 is located on one side of the detection pool 3, the lifting hydraulic cylinder 4 is firmly fixed by welding or bolting. The upper end of the lifting hydraulic cylinder 4 is tightly connected to the lifting plate 5. When the lifting hydraulic cylinder 4 is started, it can drive the lifting plate 5 to move up and down. A lifting fixing plate 6 is installed on the lifting plate 5, and the two can be connected by welding or bolts to ensure that there is no looseness during the movement. The lifting fixing plate 6 is connected to the ball support ring 8 through a strong lifting connecting rod 7. The two ends of the lifting connecting rod 7 can be fixed to the lifting fixing plate 6 and the ball support ring 8 respectively by welding or threaded connection, so that the ball support ring 8 can move synchronously with the movement of the lifting fixing plate 6. The ball support ring 8 is used to support the volleyball to be tested. Its shape and size are carefully designed to stably support the volleyball.

[0062] A clamping hydraulic cylinder 9 is also fixed on the lifting and fixing plate 6, and the clamping hydraulic cylinder 9 can be fixed on the lifting and fixing plate 6 by bolt connection or welding. The movable end of the clamping hydraulic cylinder 9 is connected to the clamping ball seat 10, and the clamping ball seat 10 and the movable end of the clamping hydraulic cylinder 9 can be threaded or welded to ensure the firmness of the connection. A clamping ball 11 is rotatably installed in the clamping ball seat 10, and the clamping ball 11 is installed in the clamping ball seat 10 by bearings or other means, so that the clamping ball 11 can rotate freely. A plurality of supporting ball seats 12 are fixedly arranged on the spherical support ring 8 in a circular array, and the supporting ball seats 12 can be fixed on the spherical support ring 8 by welding or bolt connection. A supporting ball 13 is rotatably installed in the supporting ball seat 12, and the supporting ball 13 is also installed in the supporting ball seat 12 by bearings or other means, so that the supporting ball 13 can rotate freely.

[0063] A plurality of adjusting guide rods 17 are fixed on the lifting and fixing plate 6, and one end of the adjusting guide rod 17 can be fixed on the lifting and fixing plate 6 by welding or bolting. The adjusting guide rod 17 can be movably arranged in the adjusting rod clamp 18 on the lifting plate 5, and the adjusting rod clamp 18 is fixed on the lifting plate 5 by welding or bolting. The matching between the adjusting guide rod 17 and the adjusting rod clamp 18 is relatively tight, but can slide relatively. By tightening the screws on the adjusting rod clamp 18, the position of the adjusting guide rod 17 on the adjusting rod clamp 18 can be fixed, thereby adjusting the position of the ball support ring 8 in the detection pool 3.

[0064] A plurality of lifting guide rods 19 are fixed on the lifting plate 5, and one end of the lifting guide rod 19 can be fixed on the lifting plate 5 by welding or bolt connection. The lifting guide rod 19 is movably arranged in a lifting guide sleeve 21 in a guide sleeve clamping block 20 on the bracket 1, and the lifting guide sleeve 21 is fixed in the guide sleeve clamping block 20 by interference fit or bolt connection. The lifting guide rod 19 and the lifting guide sleeve 21 are closely matched, but can slide relative to each other, ensuring that the lifting plate 5 can move up and down smoothly under the drive of the lifting hydraulic cylinder 4.

[0065] A stirring rod 22 is rotatably provided in the detection pool 3, and both ends of the stirring rod 22 are mounted on the side walls of the detection pool 3 by bearings or the like, so that the stirring rod 22 can rotate freely. A plurality of stirring plates 23 arranged in a spiral form are rotatably installed on the stirring rod 22, and the stirring plates 23 can be fixed on the stirring rod 22 by welding or bolting. The function of the stirring rod 22 and the stirring plates 23 is to stir the soapy water in the detection pool 3, increase the fluidity of the detection liquid, enable the detection liquid to more fully contact the surface of the volleyball immersed therein, and improve the accuracy of the detection.

[0066] The cylinder 30 on the bracket 1 is fixed to the bracket 1 by bolt connection or welding. A one-way valve 31 is fixed to one end of the cylinder 30, and the one-way valve 31 can be fixed to the cylinder 30 by thread connection or welding. An exhaust pipe 32 is fixed to the bottom center of the detection pool 3, and the exhaust pipe 32 can be fixed to the detection pool 3 by welding or thread connection. The one-way valve 31 and the exhaust pipe 32 are fixedly connected by a pipeline, and the pipeline can be connected to the one-way valve 31 and the exhaust pipe 32 by welding or thread connection. When the lifting hydraulic cylinder 4 descends, one of the lifting guide rods 19 drives the piston 33 to squeeze the air in the cylinder 30, and the air in the cylinder 30 flows to the exhaust pipe 32 through the one-way valve 31 and the pipeline, and then the gas is discharged into the detection liquid through the exhaust pipe 32. Due to the presence of the one-way valve 31, the detection liquid will not flow back into the cylinder 30. The gas discharged from the exhaust pipe 32 can also further increase the fluidity of the detection liquid, so that the detection liquid is in more sufficient contact with the surface of the volleyball.

[0067] The guide rod clamp 24 on the bracket 1 is fixed to the bracket 1 by welding or bolting. The guide rod clamp 24 is fixed with a guide rod 25, and the two ends of the guide rod 25 can be fixed to the guide rod clamp 24 by welding or threading.

A driven gear 29 is fixed to one end of the stirring rod 22, and the driven gear 29 and the stirring rod 22 can be fixed by key connection or welding. The driven gear 29 is meshed with the rack 28 for transmission. When the lifting hydraulic cylinder 4 is lifted or lowered, one of the lifting guide rods 19 drives the rack 28 to move linearly on the guide rod 25, and the rack 28 drives the driven gear 29 to rotate. The rotation of the driven gear 29 drives the stirring rod 22 to rotate, and the stirring rod 22 drives the stirring plate 23 to stir the soapy water in the detection pool 3.

[0068] The transverse support rod 34 on the bracket 1 is fixed to the bracket 1 by welding or bolting. A cleaning telescopic cylinder 35 is fixed to the transverse support rod 34, and the cleaning telescopic cylinder 35 can be fixed to the transverse support rod 34 by bolting or welding. An arc-shaped cleaning plate 36 is fixed to the movable end of the cleaning telescopic cylinder 35, and the arc-shaped cleaning plate 36 and the movable end of the cleaning telescopic cylinder 35 can be fixed by welding or bolting. A cleaning sponge 37 is fixed to the arc-shaped cleaning plate 36, and the cleaning sponge 37 can be fixed to the arc-shaped cleaning plate 36 by glue or bolting.

[0069] The bottom of the bracket 1 is fixedly provided with a support leg 38 with adjustable height, and the support leg 38 can be fixed to the bracket 1 by threaded connection or bolt connection. By adjusting the height of the support leg 38, the overall height of the bracket 1 can be adjusted to adapt to different working environments and needs.

[0070] Working principle:

[0071] Placing and clamping the volleyball: Place the volleyball to be tested on the spherical support ring 8. At this time, the supporting balls 13 on the spherical support ring 8 can reduce the friction between the volleyball and the spherical support ring 8, so that the volleyball can be placed on the spherical support ring 8 more stably. Start the clamping hydraulic cylinder 9, and the movable end of the clamping hydraulic cylinder 9 extends to drive the clamping ball seat 10 to move toward the volleyball. When the clamping ball seat 10 contacts the volleyball, the clamping balls 11 in the clamping ball seat 10 also fit the volleyball. The clamping balls 11 and the supporting balls 13 work together to clamp the volleyball more stably and prevent the volleyball from moving or shaking during the detection process.

[0072] Immerse in the detection pool 3: Start the lifting hydraulic cylinder 4 to contract, the lifting hydraulic cylinder 4 drives the lifting plate 5 to descend, and the lifting plate 5 drives the ball support ring 8 and the clamping hydraulic cylinder 9 to descend synchronously through the lifting fixed plate 6 and the lifting connecting rod 7. As the ball support ring 8 descends, the volleyball gradually immerses in the detection pool 3. The soapy water in the detection pool 3 can fully contact the volleyball. If the volleyball has a leak, the leaked gas will contact the soapy water to produce bubbles. At the same time, the stirring rod 22 and the exhaust pipe 32 make the detection liquid contact with the surface of the volleyball more fully, thereby improving the accuracy of the detection.

[0073] Lifting and testing: After the volleyball has been soaked in the testing pool 3 for a period of time, the lifting hydraulic cylinder 4 is started to lift, and the lifting hydraulic cylinder 4 drives the lifting plate 5 to rise. The lifting plate 5 drives the ball support ring 8 and the clamping hydraulic cylinder 9 to rise synchronously through the lifting fixed plate 6 and the lifting connecting rod 7, so that the volleyball is separated from the testing liquid. At this time, the operator observes the bubbles on the surface of the volleyball to determine the leakage position of the volleyball. The volleyball leakage detection is carried out after the lifting hydraulic cylinder 4 is lifted, that is, when the volleyball is separated from the testing liquid.

[0074] Result judgment and cleaning: If bubbles appear on the volleyball, it means that the volleyball is leaking. The operator can determine the leaking position of the volleyball based on the position of the bubbles. Then start the cleaning telescopic cylinder and the waterproof driving motor 14, the waterproof driving motor 14 drives the volleyball to rotate, and the cleaning telescopic cylinder drives the cleaning sponge 37 to fit the volleyball. The cleaning sponge 37 can absorb the cleaning liquid on the volleyball and clean the cleaning liquid on the volleyball. The cleaned volleyball can be processed or repaired in the next step.

[0075] A method for detecting air leakage position in volleyball production:

[0076] S1: Adjust equipment,

[0077] According to the detection requirements, the position of the adjusting guide rod 17 in the adjusting rod clamp 18 is adjusted to change the position of the ball support ring 8 in the detection pool 3, and the screws on the adjusting rod clamp 18 are tightened to fix the adjusting guide rod 17;

[0078] S2: Place and hold the volleyball,

[0079] Place the volleyball to be tested on the ball support ring 8, start the clamping hydraulic cylinder 9, extend its movable end, and cooperate with the ball support ring 8 to clamp the volleyball to be tested;

[0080] S3: Immerse in test pool 3,

[0081] Start the lifting hydraulic cylinder 4 to retract, and drive the ball support ring 8 and the clamping hydraulic cylinder 9 to descend synchronously through the lifting fixed plate 6, so as to immerse the volleyball in the detection pool 3;

[0082] S4: Detection process,

[0083] When the volleyball is immersed in the detection pool 3, the waterproof driving motor 14 is started, and the clamping ball 11 is driven to rotate by meshing the driving bevel gear 15 and the driven bevel gear 16. The clamping ball 11 rotates and fits with the volleyball, driving the volleyball to rotate on the supporting ball 13, so that the volleyball is fully in contact with the liquid in the detection pool 3;

[0084] During the lifting process of the lifting hydraulic cylinder 4, one of the lifting guide rods 19 drives the rack 28 to move linearly on the guide rod 25, and the rack 28 drives the driven gear 29 to rotate, and the driven gear 29 rotates to drive the stirring rod 22 to rotate, and the stirring rod 22 drives the stirring plate 23 to stir the detection liquid in the detection pool 3 to increase the fluidity of the detection liquid;

[0085] At the same time, when the lifting hydraulic cylinder 4 descends, another lifting guide rod 19 will also drive the piston 33 to squeeze the air in the cylinder 30. The air in the cylinder 30 flows to the exhaust pipe 32 through the one-way valve 31 and the pipeline, and then the gas is discharged into the detection liquid through the exhaust pipe 32, further enhancing the fluidity of the detection liquid.

[0086] S5: Result judgment and cleaning,

[0087] The operator determines the leaking position of the volleyball by observing the position of the bubbles on the volleyball;

[0088] When the volleyball leaves the detection liquid, the cleaning telescopic cylinder and the waterproof driving motor 14 are started, the waterproof driving motor 14 drives the volleyball to rotate, and the cleaning telescopic cylinder drives the cleaning sponge 37 to fit the volleyball to clean the cleaning liquid on the volleyball.

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
