Description

Technical Field

[0001] This application relates to the field of steel ball assembly, and in particular, to a ball bottle device for adding balls. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field, which can automatically perform work and is a machine that realizes various functions by its own power and control ability.

[0003] When assembling robot products, a large number of steel balls are required and high precision of the steel balls is required. However, due to the variety of robot products, small batch sizes, and different sizes of steel balls within the same batch, workers need to replace and adjust the types of steel balls, which prolongs the ball adding cycle for robot products, thereby reducing the assembly efficiency of robot products. Summary of the Invention

[0004] In order to improve the problem of the assembly efficiency of robot products, this application provides a ball bottle device for adding balls.

[0005] A ball bottle device for adding balls provided by this application adopts the following technical solution: A ball bottle device for adding balls includes a bracket, a bottle body, and an adjusting component. The bottle body is connected to the bracket. The inner cavity of the bottle body is for storing steel balls. An outlet hole is opened on the surface of the bottle body, and the outlet hole is for the steel balls in the bottle body to be discharged. The adjusting component includes a clamping plate and a quick-connect plug. The clamping plate is connected to the surface of the bottle body facing the outlet hole. A sliding cavity for the end portion of the quick-connect plug to slide is opened on the clamping plate surface. The sliding direction of the quick-connect plug is perpendicular to the axis of the outlet hole, and the sliding cavity penetrates the clamping plate surface and communicates with the outlet hole. The quick-connect plug has a positioning hole for the steel ball to pass through. When the quick-connect plug slides along the inner wall of the sliding cavity towards the direction close to the outlet hole, the positioning hole communicates with the outlet hole, and the steel balls in the bottle body are discharged from the positioning hole through the outlet hole.

[0006] By adopting the above technical solution, when adding steel balls, a quick-connect plug with a positioning hole corresponding to the inner diameter required by the robot product is selected. The end portion of the quick-connect plug is embedded in the sliding cavity and slides along the inner wall of the sliding cavity towards the direction close to the outlet hole. The positioning hole communicates with the outlet hole, and the steel balls in the bottle body are discharged from the positioning hole through the outlet hole, realizing automatic ball adding to the steel balls on the robot product. When it is necessary to assemble steel balls of different models, each time only a quick-connect plug with a positioning hole corresponding to the inner diameter needs to be replaced, without redundant operations such as adjustment and debugging by workers, shortening the ball adding cycle for robot products, thereby improving the assembly efficiency of robot products.

[0007] Optionally, the adjusting assembly further includes an adjusting seat, a feeding plate, and a feeding air cylinder. A feeding cavity for the feeding plate to slide is formed in the bottom wall of the bottle body. The sliding direction of the feeding plate is parallel to the sliding direction of the quick-connect plug. The adjusting seat is connected to the surface of the bottle body facing the feeding plate, and the feeding air cylinder is connected to the surface of the adjusting seat. The axis of the piston rod of the feeding air cylinder is parallel to the sliding direction of the feeding plate. The piston rod of the feeding air cylinder is connected to the end face of the feeding plate protruding from the bottle body. A guiding cavity for accommodating steel balls is formed in the surface of the feeding plate facing the ball outlet hole. When the piston rod of the feeding air cylinder extends, it drives the feeding plate to approach the ball outlet hole. The guiding cavity communicates with the ball outlet hole, and the steel balls in the guiding cavity are discharged from the positioning hole through the ball outlet hole.

[0008] By adopting the above technical solution, multiple steel balls in the inner cavity of the bottle body are sequentially embedded in the guiding cavity. The inner wall of the guiding cavity abuts against the spherical surface of the steel balls to form a limit, realizing the limit of multiple steel balls in the guiding cavity. When assembling the steel balls, the piston rod of the feeding air cylinder extends, driving the feeding plate to slide along the inner wall of the feeding cavity towards the direction close to the ball outlet hole. The guiding cavity communicates with the ball outlet hole, and the steel balls in the guiding cavity are discharged from the positioning hole through the ball outlet hole, realizing the directional addition of steel balls and further improving the assembly efficiency of steel balls on the robot product.

[0009] Optionally, a guiding surface is provided on the bottom wall of the guiding cavity. The inclined height of the guiding surface decreases as the distance to the discharging hole decreases. The guiding surface can abut against the steel balls and guide the steel balls close to the ball outlet hole.

[0010] By adopting the above technical solution, when the guiding cavity communicates with the ball outlet hole, the inclined height of the guiding surface decreases as the distance to the discharging hole decreases. The guiding surface guides the steel balls in the guiding cavity to be discharged from the positioning hole through the ball outlet hole, making it difficult for the steel balls to get stuck on the inner wall of the guiding cavity, thus ensuring the stability of the steel ball discharging.

[0011] Optionally, the adjusting assembly further includes a guiding rod, a linear bearing I, and a positioning ring. The linear bearing I is connected to the surface of the adjusting seat. The axis of the linear bearing I is parallel to the axis of the piston rod of the feeding air cylinder. One end of the guiding rod is connected to the surface of the feeding plate, and the other end of the guiding rod passes through the inner ring of the linear bearing I and is coaxially connected to the inner wall of the inner ring of the positioning ring. When the guiding cavity communicates with the ball outlet hole, it drives the guiding rod to slide in the inner ring of the linear bearing I, and the surface of the positioning ring abuts against the surface of the linear bearing I to form a positioning.

[0012] By adopting the above technical solution, when the piston rod of the feeding cylinder extends, it drives the feeding plate to slide along the inner wall of the feeding cavity towards the direction close to the ball outlet hole, and pushes the guide rod to slide along the inner ring of the linear bearing I, so that the feeding plate is not easily deflected when sliding along the inner wall of the feeding cavity, thereby improving the accuracy of the feeding plate sliding along the inner wall of the feeding cavity; when the ball outlet hole communicates with the guide cavity, the guide rod drives the positioning ring to approach the linear bearing I and the surface of the positioning ring abuts against the surface of the linear bearing I to form a positioning, limiting the sliding distance of the feeding plate along the inner wall of the feeding cavity, so that the feeding plate can directly reach the desired height each time, which is convenient for the staff to operate conveniently, thereby improving the adding efficiency of the steel balls.

[0013] Optionally, the positioning ring includes a circular ring and a fixing screw. The inner ring of the circular ring is provided for the guide rod to pass through. A deformation cavity is formed on the surface of the circular ring, and the deformation cavity penetrates through the surface of the circular ring. A threaded hole for the fixing screw to pass through is formed on the surface of the circular ring close to the deformation cavity, and the threaded hole communicates with the deformation cavity. When the end of the fixing screw passes through the threaded hole and is screwed and fixed on the inner wall of the deformation cavity, the inner ring wall of the circular ring is deformed under pressure and presses against the outer peripheral surface of the guide rod to form a fixation.

[0014] By adopting the above technical solution, when the piston rod of the feeding cylinder extends, the feeding plate slides along the inner wall of the feeding cavity towards the direction close to the ball outlet hole, and when the guide cavity communicates with the ball outlet hole, the positioning ring is sleeved on the outer peripheral surface of the guide rod and slides along the axis of the guide rod towards the direction close to the linear bearing I. The surface of the positioning ring abuts tightly against the surface of the linear bearing I. The end of the fixing screw passes through the threaded hole and is screwed and fixed on the inner wall of the deformation cavity. The space in the deformation cavity becomes smaller, and the inner ring wall of the circular ring is deformed under pressure and presses against the outer peripheral surface of the guide rod to form a fixation, realizing the positioning of the sliding distance of the feeding plate in the feeding cavity, and ensuring that the steel balls in the guide cavity can stably pass through the ball outlet hole and be discharged from the positioning hole.

[0015] Optionally, a feeding component is connected to the surface of the bottle body. The feeding component includes a partition plate. A ball discharging hole is formed on the surface of the bottle body. The ball discharging hole is located on one side of the ball outlet hole close to the bottom of the bottle body. The ball discharging hole is for the steel balls in the inner cavity of the bottle to be discharged. A partition cavity for the partition plate to slide is formed on the bottom wall of the bottle body close to the ball discharging hole. The sliding direction of the partition plate is parallel to the sliding direction of the feeding plate. When the partition plate slides towards the direction close to the ball discharging hole, the plate surface of the partition plate abuts tightly against the inner wall of the bottle body and separates the inner cavity of the bottle and the ball discharging hole. A ball discharging surface is provided on the bottom wall of the bottle body. The inclined height of the ball discharging surface decreases as the distance to the ball discharging hole decreases. The ball discharging surface can guide the steel balls in the bottle to be discharged from the ball discharging hole.

[0016] By adopting the above technical solution, when different types of steel balls are required for the robot product, the partition plate is driven to slide along the inner wall of the partition cavity in a direction away from the ball placing hole. The ball placing hole communicates with the inner cavity of the bottle, and the ball placing surface guides the steel balls in the bottle to be discharged from the ball placing hole, realizing the rapid emptying of the steel balls in the inner cavity of the bottle. Then, the partition plate is pushed to slide along the inner wall of the partition cavity in a direction close to the ball placing hole. The plate surface of the partition plate abuts against the inner wall of the bottle and separates the inner cavity of the bottle and the ball placing hole. The required type of steel balls is injected into the inner cavity of the bottle from the opening of the bottle, achieving the purpose of quickly changing the type of steel balls, thereby further improving the assembly efficiency of the steel balls on the robot product.

[0017] Optionally, the blanking assembly further includes a ball placing cylinder, which is connected to the surface of the adjusting seat facing the partition cavity. The axis of the piston rod of the ball placing cylinder is parallel to the sliding direction of the partition plate. The partition cavity penetrates the surface of the bottle in a direction close to the ball placing cylinder. The end face of the partition plate protruding from the bottle is connected to the rod surface of the piston rod of the ball placing cylinder. When the piston rod of the ball placing cylinder extends, the plate surface of the partition plate abuts against the inner wall of the bottle and separates the inner cavity of the bottle and the ball placing hole.

[0018] By adopting the above technical solution, when it is necessary to place balls in the inner cavity of the bottle, the piston rod of the ball placing cylinder extends, pushing the partition plate to slide along the inner wall of the partition cavity in a direction close to the ball placing hole. The plate surface of the partition plate abuts against the inner wall of the bottle and separates the inner cavity of the bottle and the ball placing hole. When it is necessary to drain all the steel balls in the bottle, the piston rod of the ball placing cylinder contracts, pushing the partition plate to slide along the inner wall of the partition cavity in a direction away from the ball placing hole. The ball placing hole communicates with the inner cavity of the bottle, and the ball placing surface guides the steel balls in the inner cavity of the bottle to be discharged from the ball placing hole, without the need for staff to push the partition plate to slide, thereby further improving the simplicity of using the ball bottle device.

[0019] Optionally, the bracket is connected with a lifting assembly, and the lifting assembly includes a lifting cylinder. The bottle is slidably connected to the surface of the bracket. The sliding direction of the bottle is parallel to the axis of the piston rod of the feeding cylinder. The lifting cylinder is connected to the surface of the bracket, and the end face of the piston rod of the lifting cylinder is connected to the surface of the adjusting seat. The axis of the piston rod of the lifting cylinder is parallel to the axis of the piston rod of the feeding cylinder.

[0020] By adopting the above technical solution, when the staff uses the ball bottle device, the piston rod of the lifting cylinder extends, driving the bottle to slide along the surface of the bracket. When the height of the bottle on the bracket is suitable for the staff, it stops, enabling the height of the bottle to be adapted to staff of different heights, thereby improving the versatility of using the ball bottle device.

[0021] Optionally, the lifting assembly further includes a bearing seat, a limiting rod, a linear bearing II, and a limiting ring. The bearing seat is connected to the bracket, the linear bearing II is connected to the surface of the bearing seat, the axes of the linear bearing II and the piston rod of the lifting cylinder are parallel to each other. One end of the limiting rod is connected to the surface of the adjusting seat, the other end of the limiting rod passes through the inner ring of the linear bearing II and is coaxially connected to the inner ring wall of the limiting ring. When the bottle body slides along the surface of the bracket, the limiting rod is driven to slide along the inner ring wall of the linear bearing II, and the surface of the limiting ring abuts against the surface of the bearing seat to form a positioning.

[0022] By adopting the above technical solution, when the bowling pin device is in use, the piston rod of the lifting cylinder extends, driving the bottle body to slide along the surface of the bracket to a height suitable for the height of the staff. At this time, the limiting rod slides along the inner ring wall of the linear bearing II and drives the limiting ring to approach the bearing seat. The surface of the limiting ring abuts against the surface of the bearing seat to form a positioning, restricting the sliding of the bottle body on the surface of the bracket, so that the height of each lift of the bottle body is suitable for the height of the staff, and there is no need for the staff to adjust the height of the bottle body on the bracket before each use, thus further improving the simplicity of using the bowling pin device.

[0023] Optionally, an installation assembly is connected between the bearing seat and the bracket. The installation assembly includes a positioning screw and a positioning nut. A fixing cavity for the bracket to be embedded is provided on the surface of the bearing seat. A positioning cavity for the positioning nut to slide is provided on the surface of the bracket facing the fixing cavity. The sliding direction of the positioning nut is parallel to the axis of the piston rod of the lifting cylinder. The positioning cavity communicates with the fixing cavity, and the opening of the positioning nut faces the fixing cavity. An installation hole for the end of the positioning screw to pass through is provided on the surface of the bearing seat. The end of the positioning screw can pass through the installation hole and be screwed and fixed on the inner cavity wall of the positioning nut to form a positioning, and the bearing seat is limited on the surface of the bracket.

[0024] By adopting the above technical solution, when the staff uses the bowling pin device, the piston rod of the lifting cylinder extends, driving the bottle body to slide along the surface of the bracket. When the height of the bottle body on the bracket is suitable for the staff, it stops. The bearing seat is driven to slide along the surface of the bracket towards the direction close to the limiting ring, and the surface of the bearing seat abuts against the surface of the limiting ring to form a positioning. At the same time, the positioning nut is driven to slide along the inner wall of the positioning cavity towards the direction close to the bearing seat. The opening of the positioning nut faces the installation hole. The end of the positioning screw passes through the installation hole and is screwed and fixed on the inner cavity wall of the positioning nut to form a positioning, and the bearing seat is limited on the surface of the bracket. When the staff operates the bowling pin device next time, there is no need to adjust the sliding distance of the bottle body on the surface of the bracket again, so that the sliding distance of the bottle body on the bracket each time is suitable for the height of the staff, which is convenient for the staff to operate smoothly and further improves the adding efficiency of steel balls in the robot product.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the quick-connect plug and the clamping plate only requires replacing the quick-connect plug with a positioning hole having a corresponding inner diameter each time, without the need for extra operations such as adjustment and debugging by the staff, shortening the ball-adding cycle for the robot product, and thus improving the assembly efficiency of the robot product. 2. The setting of the adjusting seat, the feeding plate and the feeding cylinder enables the steel balls in the guiding cavity to be discharged from the positioning hole through the ball outlet hole, realizing the directional discharging of the steel balls, and further improving the assembly efficiency of the steel balls on the robot product. 3. The setting of the guiding surface guides the steel balls in the guiding cavity to be discharged from the positioning hole through the ball outlet hole, making it difficult for the steel balls to get stuck on the inner wall of the guiding cavity, and thus ensuring the stability of the ball discharging.

Detailed implementation mode

[0033] The following will further elaborate on this application in conjunction with the attached Figure 1-6 drawings for a more detailed description.

[0034] An embodiment of this application discloses a bowling pin device for adding balls. Referring to Figure 1 , a bowling pin device for adding balls includes a bracket 1, a bottle body 2, and an adjustment assembly 3. The bottom of the bracket 1 is fixed with casters 4 through bolts. The wheel surface of the casters 4 is in rolling contact with the ground. Rolling friction replaces sliding friction, reducing the frictional force, thereby facilitating the flexible movement of the staff for the bracket 1; an adjustment cavity 11 for the bottle body 2 to slide is provided at the top of the bracket 1. The sliding direction of the bottle body 2 is parallel to the height direction of the bracket 1. The opening of the bottle body 2 is for steel balls to be loaded into the inner cavity of the bottle body 2. The adjustment assembly 3 is installed on the bottle body 2, and the adjustment assembly 3 can adjust the batch discharge of the steel balls in the bottle body 2.

[0035] Referring to Figure 1 and Figure 2 , the adjustment assembly 3 includes a clamping plate 31, a quick-connect plug 32, an adjustment seat 33, a feeding plate 34, a feeding cylinder 35, a guide rod 36, a linear bearing one 37, and a positioning ring 38; a ball outlet hole 21 is provided on the surface of the bottle body 2. The axis of the ball outlet hole 21 is parallel to the length direction of the bracket 1. The ball outlet hole 21 penetrates the surface of the bottle body 2 along its own axis and communicates with the inner cavity of the bottle body 2. The ball outlet hole 21 is for the steel balls in the bottle body 2 to be discharged. The clamping plate 31 is fixed to the surface of the bottle body 2 facing the ball outlet hole 21 through bolts. A sliding cavity 311 for the end of the quick-connect plug 32 to slide is provided on the plate surface of the clamping plate 31. The sliding direction of the quick-connect plug 32 is parallel to the length direction of the bracket 1. The sliding cavity 311 penetrates both sides of the clamping plate 31 and communicates with the ball outlet hole 21. A positioning hole 321 for the steel balls to pass through is provided on the surface of the quick-connect plug 32 facing the ball outlet hole 21. The axis of the positioning hole 321 is parallel to the axis of the ball outlet hole 21. The positioning hole 321 penetrates both sides of the quick-connect plug 32 along its own axis. The inner diameter of the positioning hole 321 is adapted to the diameter of the steel balls. When the quick-connect plug 32 slides along the inner wall of the sliding cavity 311 towards the direction close to the ball outlet hole 21, the positioning hole 321 communicates with the ball outlet hole 21, and the steel balls in the inner cavity of the bottle body 2 are quantitatively discharged through the ball outlet hole 21 from the positioning hole 321, realizing the directional addition of a batch of steel balls to the robot product.

[0036] Referring to Figure 1 and Figure 2 , when it is necessary to assemble steel balls of different models, each time only the quick-connect plug 32 with a positioning hole 321 of the corresponding inner diameter needs to be installed, without the need for the staff to perform redundant actions such as adjustment and debugging, achieving the purpose of quickly replacing the quick-connect plug to replace the steel balls, saving a large amount of time for small-batch and multi-variety steel balls, shortening the ball-adding cycle for the robot product, and thus improving the assembly efficiency of the robot product.

[0037] Referring toFigure 2 and Figure 3 The adjusting seat 33 is fixed to the bottom of the bottle body 2. A feeding cavity 22 for the feeding plate 34 to slide is formed in the bottom wall of the bottle body 2. The sliding direction of the feeding plate 34 is parallel to the height direction of the bracket 1. The feeding cavity 22 penetrates the outer wall of the bottle body 2 towards the direction close to the adjusting seat 33. The feeding air cylinder 35 is fixed to the surface of the adjusting seat 33 by bolts. An electromagnetic valve II 5 is installed on the surface of the adjusting seat 33. The electromagnetic valve II 5 is used to control the driving of the feeding air cylinder 35. The axis of the piston rod of the feeding air cylinder 35 is parallel to the height direction of the bracket 1. The piston rod of the feeding air cylinder 35 faces the feeding plate 34. The end of the feeding plate 34 protruding from the bottom of the bottle body 2 is fixed to the rod surface of the piston rod of the feeding air cylinder 35 by bolts. A guiding cavity 341 for accommodating steel balls is formed in the end face of the feeding plate 34 located in the inner cavity of the bottle body 2. The inner wall of the guiding cavity 341 abuts against the surface of the steel balls and confines the steel balls in the guiding cavity 341, thereby improving the limiting stability of the steel balls in the guiding cavity 341.

[0038] Refer to Figure 2 and Figure 3 As shown in FIGS. and, a guiding surface 342 is provided on the bottom wall of the guiding cavity 341. The inclined height of the guiding surface 342 decreases as the distance to the discharging hole decreases. The guiding surface 342 can abut against the spherical surface of the steel balls and guide the steel balls to roll towards the direction close to the ball discharging hole 21, providing guidance for the steel balls to roll on the inner wall of the guiding cavity 341, thereby improving the stability of the steel balls discharged from the positioning hole 321.

[0039] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the number of the linear bearings I 37 can be one, two or more. In the embodiment of the present application, the number of the linear bearings I 37 is two. The two linear bearings I 37 are fixedly spaced on both sides in the length direction of the adjusting seat 33 by bolts. The axis of the linear bearings I 37 is parallel to the height direction of the bracket 1. The number of the guiding rods 36 can be one, two or more. In the embodiment of the present application, the number of the guiding rods 36 is two. One ends of the two guiding rods 36 are fixedly corresponding to both ends in the length direction of the feeding plate 34 respectively, and the other ends of the two guiding rods 36 penetrate through the two linear bearings I 37 respectively.

[0040] Refer to Figure 2 and Figure 4, the number of positioning rings 38 can be one, two, or more. In the embodiment of the present application, the number of positioning rings 38 is two, and the positioning rings 38 correspond to the guide rods 36 one by one. The positioning ring 38 includes a circular ring 381 and a fixing screw 382. The inner ring of the circular ring 381 is for the guide rod 36 to pass through. A deformation cavity 3811 is formed on the surface of the circular ring 381. The deformation cavity 3811 penetrates both sides of the circular ring 381 in the axial direction, and the deformation cavity 3811 penetrates the outer peripheral surface of the circular ring 381 in a direction away from the axis of the circular ring 381. A threaded hole 3812 for the fixing screw 382 to transmit is formed on the surface of the circular ring 381 near the deformation cavity 3811. The axis of the threaded hole 3812 is perpendicular to the axis of the circular ring 381, and the threaded hole 3812 communicates with the deformation cavity 3811.

[0041] Referring to Figure 2 and Figure 3 , when the steel balls enter the inner cavity of the bottle body 2 through the opening of the bottle body 2, some of the steel balls in the inner cavity of the bottle body 2 are embedded in the guide cavity 341. The inner wall of the guide cavity 341 abuts against the spherical surface of the steel balls to form a limit. The staff selects a quick-connect plug 32 with a positioning hole 321 having the same inner diameter according to the diameter of the steel balls. The end of the compatible quick-connect plug 32 is embedded in the sliding cavity 311 and slides along the inner wall of the sliding cavity 311 in the direction close to the ball outlet hole 21. The ball outlet hole 21 communicates with the positioning hole 321, realizing the quick installation of the quick plug on the bottle body 2; at the same time, the piston rod of the feeding cylinder 35 extends, pushing the feeding plate 34 to slide along the inner wall of the feeding cavity 22 in the direction close to the ball outlet hole 21. The ball outlet hole 21 communicates with the guide cavity 341, and the guide surface 342 guides the steel balls in the guide cavity 341 to roll in the direction close to the ball outlet hole 21. Multiple steel balls in the guide cavity 341 sequentially pass through the ball outlet hole 21 and are discharged from the positioning hole 321, realizing the batch addition of the same type of steel balls.

[0042] Referring to Figure 2 and Figure 4 , at the same time, the circular ring 381 is coaxially sleeved on the outer peripheral surface of the guide rod 36 and slides along the axis of the guide rod 36 in the direction close to the linear bearing. The end face of the circular ring 381 abuts against the surface of the linear bearing. The end of the fixing screw 382 passes through the threaded hole 3812 and is fixedly screwed on the inner wall of the deformation cavity 3811 to form a fixation. The space in the deformation cavity 3811 becomes smaller, and the inner ring wall of the circular ring 381 is deformed under pressure and abuts against the outer peripheral surface of the guide rod 36 to form a fixation, realizing the directional fixation of the guide ring along the axis of the guide rod 36 and limiting the sliding distance of the feeding plate 34 in the feeding cavity 22, so that the feeding plate 34 can directly reach the desired height each time; when the model size of the steel balls in the bottle body 2 is changed, the sliding distance of the feeding plate 34 does not need to be adjusted again, ensuring that the bottle body 2 device only needs to set the sliding distance of the feeding plate 34 during the first use, and only needs to replace the quick plug with an inner diameter compatible with the positioning hole 321 when the model size of the steel balls is changed later, which is convenient for the staff to operate smoothly, thereby improving the efficiency of adding steel balls.

[0043] Refer to Figure 3 and Figure 5 As shown in, a blanking component 6 is installed on the bottle body 2, and the blanking component 6 can quickly discharge all the steel balls in the inner cavity of the bottle body 2; the blanking component 6 includes a partition plate 61 and a ball discharging cylinder 62. A ball discharging hole 23 is formed on the surface of the bottle body 2 close to the adjusting seat 33. The axis of the ball discharging hole 23 is parallel to the axis of the ball outlet hole 21. The ball discharging hole 23 penetrates through the surface of the bottle body 2 along its own axis and communicates with the inner cavity of the bottle body 2. The ball discharging hole 23 is used for discharging the steel balls in the inner cavity of the bottle body 2. The bottom wall of the bottle body 2 is provided with a ball discharging surface 24. The inclined height of the ball discharging surface 24 decreases as the distance to the ball discharging hole 23 decreases. The ball discharging surface 24 can guide the steel balls in the bottle body 2 to roll towards the direction close to the ball discharging hole 23 and be discharged from the ball outlet hole 21, thereby improving the emptying efficiency of the steel balls in the inner cavity of the bottle body 2.

[0044] Refer to Figure 1 and Figure 3 As shown in, a partition cavity 25 for the partition plate 61 to slide is formed on the bottom wall of the bottle body 2 close to the ball discharging hole 23. The sliding direction of the partition plate 61 is parallel to the height direction of the bracket 1. The partition cavity 25 penetrates through the bottom of the bottle body 2. The ball discharging cylinder 62 is fixed on the surface of the adjusting seat 33 by bolts. The bracket 1 is installed with a control switch 7, and the control switch 7 can control the driving of the ball discharging cylinder 62.

[0050] The implementation principle of a bowling pin device for adding balls in an embodiment of this application is as follows: When steel balls enter the inner cavity of the bottle body 2 through the opening of the bottle body 2, some of the steel balls in the inner cavity of the bottle body 2 are embedded in the guiding cavity 341, and the inner wall of the guiding cavity 341 abuts against the spherical surface of the steel balls to form a limit. The staff selects a quick-connect plug 32 with a positioning hole 321 of the same inner diameter according to the diameter of the steel balls. The end of the compatible quick-connect plug 32 is embedded in the sliding cavity 311 and slides along the inner wall of the sliding cavity 311 towards the direction close to the ball outlet hole 21. The ball outlet hole 21 communicates with the positioning hole 321, realizing the quick installation of the quick plug on the bottle body 2. At the same time, the piston rod of the feeding cylinder 35 extends, pushing the feeding plate 34 to slide along the inner wall of the feeding cavity 22 towards the direction close to the ball outlet hole 21. The ball outlet hole 21 communicates with the guiding cavity 341, and the guiding surface 342 guides the steel balls in the guiding cavity 341 to roll towards the direction close to the ball outlet hole 21. Multiple steel balls in the guiding cavity 341 sequentially pass through the ball outlet hole 21 and are discharged from the positioning hole 321. When the addition of steel balls in the inner cavity of the bottle body 2 is completed and different types of steel balls need to be replaced, the piston rod of the ball discharging cylinder 62 contracts, driving the partition plate 61 to slide along the inner wall of the partition cavity 25 away from the bottle body 2. The inner cavity of the bottle body 2 communicates with the ball discharging hole 23, and the ball discharging surface 24 guides the steel balls in the inner cavity of the ball towards the direction close to the ball discharging hole 23 and discharges them from the ball discharging hole 23, realizing the quick emptying of the steel balls in the bottle body 2. When it is necessary to supplement the required type of steel balls into the inner cavity of the bottle body 2, the piston of the ball discharging cylinder 62 extends, driving the partition plate 61 to slide along the inner wall of the partition cavity 25 towards the direction close to the bottle body 2. The plate surface of the partition plate 61 abuts tightly against the inner wall of the bottle body 2 and separates the ball discharging hole 23 and the inner cavity of the bottle body 2. Multiple steel balls of the required type enter the inner cavity of the bottle body 2 through the opening of the bottle body 2, realizing the quick replacement of different types in the inner cavity of the bottle body 2, thereby further improving the adding efficiency of steel balls to the robot product. Finally, it is only necessary to replace the quick plug with an inner diameter of the positioning hole 321 that is compatible with the required type of steel balls, which is convenient for the staff to operate smoothly, thereby improving the adding efficiency of the steel balls. There is no need for the staff to perform redundant operations such as adjustment and debugging, shortening the ball adding cycle of the robot product, and thus improving the assembly efficiency of the robot product.

[0051] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
