Description

A multi-channel ball-slider ball-filling device with buffer Technical Field

[0001] This utility model relates to the technical field of steel ball filling equipment, and in particular to a multi-channel ball-slider filling equipment with buffer. Background Technology

[0002] Ball bearing slides are widely used linear motion guiding elements in mechanical equipment. They typically consist of a slide body, steel balls, a cage, and a guide rail. The steel balls, usually high-precision spheres, are the key components for achieving linear motion. The guide rail is the track that mates with the slide and is typically mounted on a fixed component of the equipment, providing precise linear motion guidance for the slide. Referring to Figure 1, when the slide moves on the guide rail, the steel balls roll within the raceway between the slide and the guide rail. Due to the small contact area between the steel balls and the guide rail and slide, the coefficient of friction is low, thus enabling high-precision, low-friction linear motion.

[0003] Currently, most manufacturers in the domestic market use manual labor with tools and fixtures to fill ball bearing blocks with steel balls. This requires manual intervention to ensure the correct number of steel balls is filled, resulting in low production efficiency and the risk of errors in the filling quantity, which affects the quality of the ball bearing blocks. This manual method of filling steel balls is far from meeting the market's demands for both quality and quantity. Furthermore, during filling, the most suitable tolerance steel balls need to be selected based on the measured dimensions of the ball bearing channels inside the block. Existing ball filling equipment cannot automatically select different tolerance specifications based on the channel dimensions of the block, resulting in long filling times and the inability to continuously fill four rows of steel balls in the block. Incorrect ball ball specifications can also cause the product to fail to reach the target preload level, thus affecting product accuracy. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multi-channel ball bearing slider filling device with buffer, which can automatically select steel balls of specific tolerance specifications according to filling needs and automatically and quickly fill them. This effectively solves the technical problems of low working efficiency, easy error in steel ball quantity, and inability of existing steel ball filling devices to automatically select steel balls of different sizes for rapid filling.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] One technical solution of this utility model provides a multi-channel ball-slider filling steel ball device with buffer, including a steel ball dispensing mechanism, an air blowing mechanism, a pipeline switching mechanism and a steel ball filling mechanism;

[0007] The steel ball dispensing mechanism includes several dispensing devices arranged side by side, a set of steel ball punching mechanisms, and a synchronous belt linear module of a motor that drives the steel ball punching mechanisms to move. The steel ball punching mechanism includes an up-and-down vibration mechanism and a pushing mechanism. The discharge end of the dispensing device is connected to an air blowing mechanism and a pipeline switching mechanism through pipelines respectively.

[0008] The steel ball filling mechanism includes a cylinder linear module, a filling drive mechanism, and a push rod drive mechanism. The cylinder linear module is equipped with a tooling slider with steel balls to be filled. The rear end of the filling drive mechanism is connected to a pipeline switching mechanism through a pipeline, and the front end is connected to the steel ball channel inside the tooling slider. The push rod drive mechanism is used to push the steel balls from the internal channel of the filling drive mechanism into the steel ball channel.

[0009] During operation, driven by the synchronous belt linear module of the motor, the steel ball feeding mechanism moves close to the designated distributor. The up-and-down vibration mechanism pushes the steel balls out of the distributor, and the pushing mechanism pushes the steel balls from the distributor into the pipeline. The air blowing mechanism is activated to push the steel balls along the pipeline through the airflow. After passing through the pipeline switching mechanism, the steel balls enter the filling drive mechanism. The push rod drive mechanism pushes the steel balls into the steel ball channel in sequence to realize the filling of steel balls by the tooling slider.

[0010] Furthermore, the distributor includes steel ball tanks, which store steel balls of different tolerance specifications. Below the steel ball tanks are four sets of parallel discharge channels. Each set of discharge channels includes a hollow top discharge channel, a buffer channel, a steel ball pusher, and a steel ball discharge plate connected in sequence. The cavities of the top discharge channel and the buffer channel are coaxial, while the cavities of the buffer channel and the steel ball discharge plate are not coaxial.

[0011] A vibrating clamping plate is fitted on the outside of the ejector channel, and a pusher clamping plate is provided between the buffer channel and the steel ball discharge plate. The steel ball pusher rod is movably set inside the pusher clamping plate.

[0012] The upper and lower vibration mechanism is connected to the vibrating clamp of the material channel to drive the ejector channel to move up and down to eject the steel balls in the steel ball tank. The steel balls enter the buffer channel through the ejector channel.

[0013] The pushing mechanism is connected to a steel ball pushing rod to drive the steel ball pushing rod to move horizontally within the pushing sandwich plate. The steel ball falls from the buffer channel into the steel ball pushing rod. When the cavity of the steel ball pushing rod is coaxial with the cavity of the steel ball discharge plate, the steel ball falls into the steel ball discharge plate.

[0014] The air blowing mechanism is connected to the inner cavity of the steel ball feeding plate through a pipeline. The pipeline switching mechanism is connected to the steel ball feeding plate and the filling drive mechanism through pipelines respectively. The air blowing mechanism blows air into the cavity of the steel ball feeding plate to push the steel ball to slide along the pipeline and enter the filling drive mechanism after passing through the pipeline switching mechanism. It can continuously fill four rows of steel balls in the slider.

[0015] Furthermore, the ball-firing mechanism also includes a sliding mounting base connected to the synchronous belt linear module of the motor, and the upper and lower vibration mechanism includes a vertical drive cylinder, upper and lower vibration plates, a lever drive cylinder, and a ball channel lever;

[0016] The vertical drive cylinder is fixed above the sliding mounting base. The piston output end of the vertical drive cylinder is vertically set and fixedly connected to the upper and lower vibration plates. The lever drive cylinder is fixed on the upper and lower vibration plates. The piston output end of the lever drive cylinder is horizontally set and connected to the steel ball channel lever. The front end of the steel ball channel lever is provided with an insertion block. The material channel vibration clamp plate is provided with an insertion hole that matches the shape of the insertion block.

[0017] During operation, the synchronous belt of the motor drives the steel ball ejection mechanism to move to the vicinity of the designated distributor. The lever-driven cylinder drives the steel ball channel lever to extend outward, and the insert block is inserted into the insertion hole. Then, the vertical drive cylinder drives the upper and lower vibrating plates to move vertically, while simultaneously driving the material channel vibrating clamp and the ejector channel to move up and down. This causes the upper end of the ejector channel to eject the steel balls stored in the steel ball tank. The steel balls fall into the ejector channel in sequence and then enter the buffer channel.

[0018] Furthermore, the pushing mechanism includes four sets of horizontally arranged pushing cylinders, which are fixedly connected to the sliding mounting base. When the piston output end of each pushing cylinder extends outward, it abuts against the steel ball pushing rod, driving the steel ball pushing rod to move inside the pushing sandwich plate. When the inner cavity of the steel ball pushing rod is coaxial with the inner cavity of the buffer channel, the steel ball in the buffer channel falls into the inner cavity of the steel ball pushing rod. The inner cavity of the steel ball pushing rod can only hold one steel ball. When the pushing cylinder drives the steel ball pushing rod to move to the coaxial position with the inner cavity of the steel ball unloading plate, the steel ball in the steel ball pushing rod falls into the inner cavity of the steel ball unloading plate. Then, the air blowing mechanism blows air into the inner cavity of the steel ball unloading plate. The airflow pushes the steel ball to slide along the pipeline, pass through the pipeline switching mechanism, and enter the filling drive mechanism.

[0019] Furthermore, the motor synchronous belt linear module includes a servo motor, a motor synchronous pulley that rotates coaxially with the motor shaft of the servo motor, and two sets of spaced rotating shaft synchronous pulley assemblies. The motor synchronous pulley and one set of rotating shaft synchronous pulley assemblies are connected and rotate synchronously through a primary synchronous belt, and the two sets of rotating shaft synchronous pulley assemblies are connected and rotate synchronously through a secondary synchronous belt. A synchronous belt pressure plate is provided at the bottom of the sliding mounting base and connected to the secondary synchronous belt to achieve synchronous linkage. Two sets of parallel first linear guide rails are provided below the sliding mounting base, and the sliding mounting base is slidably connected to the first linear guide rails through the first guide rail slider.

[0020] Furthermore, the air blowing mechanism includes a pneumatic solenoid valve island, which is connected to the inner cavity of each steel ball feeding plate through several pipelines. It can blow air into the inner cavity of each steel ball feeding plate individually to control the sliding of the steel balls in each pipeline.

[0021] Each ball feeder plate has a set of ring sensor components installed below it. The connecting pipe between the ball feeder plate and the pipe switching mechanism passes through the ring sensor components to detect whether the ball falls normally and to output the specific pipe position and number of balls. When a ball in a certain pipe fails to fall, the ring sensor components will feed the monitoring data back to the control backend, start the vertical drive cylinder to drive the upper and lower vibrating plates to vibrate and fall the ball, and separately start the pusher cylinder of that pipe to push the ball pusher rod to transport the ball to the ball feeder plate.

[0022] Furthermore, the pipeline switching mechanism includes a parallel set of fixed pipelines, a linear motor module, and a movable pipeline. The fixed pipelines are sequentially connected to the steel ball feeding plates via pipelines. The movable pipelines are sequentially connected to the air pipe connectors on the filling drive mechanism via pipelines. Driven by the linear motor module, the movable pipelines move along the arrangement direction of the fixed pipelines and dock with the designated pipeline interfaces on the fixed pipelines, forming a closed airflow channel to facilitate the sliding of the steel balls. Based on the specific dimensions of the steel ball grooves inside the tooling slider of the steel ball to be filled, the movable pipelines connect to the pipeline interfaces on the fixed pipelines corresponding to the tolerance specifications of the steel balls, and the steel balls are pushed to the filling drive mechanism by airflow.

[0023] Furthermore, the linear cylinder module includes a rodless cylinder, two parallel second linear guides, second guide sliders, and a tooling limit seat. At least two second guide sliders are fixed to the bottom of the tooling limit seat. The second guide sliders are slidably connected to the second linear guides. Driven by the rodless cylinder, the tooling limit seat moves the tooling sliders along the second linear guides to the designated filling position.

[0024] Furthermore, the filling drive mechanism includes two filling drive cylinders, two parallel third linear guide rails, and a third guide rail slider slidably connected to the third linear guide rails. Each filling drive cylinder is connected to a material channel seat, and each material channel seat has a fixed steel ball filling channel. The front end of each steel ball filling channel is connected to a material channel head. The filling drive cylinder drives the material channel seat to slide along the third linear guide rail, inserting the material channel head into the interior of the tooling slider. The rear end of each steel ball filling channel is connected to the moving pipeline through two air pipe joints. The steel balls are pushed from the moving pipeline into the two air pipe joints by airflow, and under the action of the push rod drive mechanism, they enter the steel ball channel and the steel ball channel inside the material channel head in two separate paths, and finally enter the steel ball groove inside the tooling slider.

[0025] Furthermore, the push rod drive mechanism includes a push rod drive motor, a ball screw assembly, a slider connecting seat, and four long ball push rods. The push rod drive motor and the ball screw assembly are connected and rotate synchronously via a synchronous belt assembly. The slider connecting seat is fitted onto the outside of the ball screw assembly to form a threaded connection. The rear end of the long ball push rod is fixedly connected to the slider connecting seat. Under the drive of the push rod drive motor, the slider connecting seat moves along the ball screw assembly, while simultaneously driving the long ball push rods to be inserted sequentially into the ball channels inside the ball filling channel and the channel head, pushing the balls into the ball grooves inside the tooling slider.

[0026] This utility model has the following beneficial effects:

[0027] This utility model provides a multi-channel ball bearing slider filling device with buffer, which can buffer steel balls of the same diameter but different tolerance specifications in multiple channels. During use, it can automatically select steel balls according to the dimensional tolerance of the steel ball channels inside the ball bearing slider and automatically and quickly fill them, reducing the waiting time for steel ball discharge, greatly increasing the output per unit time, and improving the accuracy of the filling steel ball quantity. It can meet the multiple needs of ball bearing slider manufacturers in the market for the output, efficiency and quality of ball bearing slider products. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0054] Referring to Figure 2, this embodiment provides a multi-channel ball bearing slider filling device with buffer, including a ball bearing distribution mechanism 1, an air blowing mechanism 2, a pipeline switching mechanism 3, and a ball filling mechanism 4. Referring to Figures 3 to 9, the ball bearing distribution mechanism 1 includes several parallel-arranged distributors 110, a set of ball bearing mechanisms 120, and a synchronous belt linear module 130 for driving the ball bearing mechanisms 120. The ball bearing mechanism 120 includes an up-and-down vibration mechanism 121 and a pushing mechanism 122. The discharge end of the distributors 110 is connected to the air blowing mechanism 2 and the pipeline switching mechanism 3 through pipelines.

[0055] Referring to Figures 11 to 14, the steel ball filling mechanism 4 includes a cylinder linear module 410, a filling drive mechanism 420, and a push rod drive mechanism 430. A tooling slider 5 with steel balls to be filled is mounted on the cylinder linear module 410. The rear end of the filling drive mechanism 420 is connected to a pipeline switching mechanism 3 via a pipeline, and the front end is connected to the steel ball channel 510 inside the tooling slider 5. The push rod drive mechanism 430 is used to push the steel balls from the internal channel of the filling drive mechanism 420 into the steel ball channel 510.

[0056] During operation, driven by the synchronous belt linear module 130 of the motor, the steel ball dispensing mechanism 120 moves closer to the designated distributor 110. The up-and-down vibration mechanism 121 pushes the steel balls out of the distributor 110, and then the pushing mechanism 122 pushes the steel balls from the distributor 110 into the pipeline. The air blowing mechanism 2 is activated to push the steel balls along the pipeline through the airflow. After passing through the pipeline switching mechanism 3, the steel balls enter the filling drive mechanism 420. The push rod drive mechanism 430 pushes the steel balls into the steel ball channel 510 in sequence to realize the filling of steel balls into the tooling slider 5.

[0057] Specifically, referring to Figures 3, 4, and 6, the distributor 110 includes a ball bearing tank 111 for storing ball bearings of the same diameter but different tolerance specifications. Below the ball bearing tank 111 are four sets of parallel discharge channels. Each set of discharge channels includes a hollow top discharge channel 112, a buffer channel 113, a ball bearing pusher 114, and a ball bearing unloading plate 115 connected in sequence. The cavities of the top discharge channel 112 and the buffer channel 113 are coaxial, while the cavities of the buffer channel 113 and the ball bearing unloading plate 115 are not coaxial. A vibrating clamping plate 116 is fitted around the top discharge channel 112. A pusher clamping plate 117 is provided between the buffer channel 113 and the ball bearing unloading plate 115, and the ball bearing pusher 114 is movably disposed within the pusher clamping plate 117. The vertical vibration mechanism 121, connected to the vibrating clamp 116 of the feed channel, drives the ejector feed channel 112 to move up and down, ejecting the steel balls from the steel ball tank 111. The steel balls then enter the buffer feed channel 113 through the ejector feed channel 112. The pushing mechanism 122, connected to the steel ball pushing rod 114, drives the steel ball pushing rod 114 to move horizontally within the pushing clamp plate 117. The steel balls fall from the buffer feed channel 113 into the steel ball pushing rod 114. When the cavity of the steel ball pushing rod 114 is coaxial with the cavity of the steel ball discharge plate 115, the steel balls fall into the steel ball discharge plate 115.

[0058] The air blowing mechanism 2 is connected to the inner cavity of the steel ball feeding plate 115 through a pipeline. The pipeline switching mechanism 3 is connected to the steel ball feeding plate 115 and the filling drive mechanism 420 through pipelines respectively. The air blowing mechanism 2 blows air into the cavity of the steel ball feeding plate 115 to push the steel ball to slide along the pipeline, pass through the pipeline switching mechanism 3 and enter the filling drive mechanism 420.

[0059] Referring to Figures 3, 5, and 6, the ball-firing mechanism 120 also includes a sliding mounting base 123 connected to the synchronous belt linear module 130 of the motor. The upper and lower vibration mechanism 121 includes a vertical drive cylinder 1211, upper and lower vibration plates 1212, a lever drive cylinder 1213, and a ball channel lever 1214. The vertical drive cylinder 1211 is fixed above the sliding mounting base 123. The piston output end of the vertical drive cylinder 1211 is vertically arranged and fixedly connected to the upper and lower vibration plates 1212. The lever drive cylinder 1213 is fixed on the upper and lower vibration plates 1212. The piston output end of the lever drive cylinder 1213 is horizontally arranged and connected to the ball channel lever 1214. Referring to Figure 7, the front end of the ball channel lever 1214 is provided with an insertion block 1215, and the material channel vibration clamp plate 116 is provided with an insertion hole 1161 that matches the shape of the insertion block 1215.

[0060] During operation, the synchronous belt linear module 130 of the motor drives the ball-beating mechanism 120 to move to the vicinity of the designated distributor 110 and dock with it. The lever-driven cylinder 1213 drives the ball channel lever 1214 to extend outward, and the insert block 1215 is inserted into the insertion hole 1161. Then, the vertical drive cylinder 1211 drives the upper and lower vibrating plates 1212 to move vertically, while simultaneously driving the material channel vibrating clamp 116 and the ejection channel 112 to move up and down. As a result, the ejection channel 112 agitates the steel balls stored in the ball tank 111 and ejects a set number of steel balls. The steel balls fall into the ejection channel 112 in sequence and then enter the buffer channel 113. During filling, the steel balls in the buffer channel 113 are used first, and then the ball-beating mechanism 120 replenishes the steel balls in the buffer channel 113. This design can reduce the waiting time for steel balls to be ejected during filling, thereby saving cycle time.

[0061] Referring to Figures 3, 5 and 6, the pushing mechanism 122 includes four sets of horizontally arranged pushing cylinders 1221. The pushing cylinders 1221 are fixedly connected to the sliding mounting base 123. When the piston output end of each set of pushing cylinders 1221 extends outward, it abuts against the steel ball pushing rod 114, driving the steel ball pushing rod 114 to move inside the pushing interlayer plate 117. When the inner cavity of the steel ball pusher 114 is coaxial with the inner cavity of the buffer channel 113, the steel ball in the buffer channel 113 falls into the inner cavity of the steel ball pusher 114. The inner cavity of the steel ball pusher 114 can only hold one steel ball. When the pusher cylinder 1221 drives the steel ball pusher 114 to move to the inner cavity of the steel ball discharge plate 115, the steel ball in the steel ball pusher 114 falls into the inner cavity of the steel ball discharge plate 115. Then the air blowing mechanism 2 blows air into the inner cavity of the steel ball discharge plate 115. The airflow pushes the steel ball to slide along the pipeline and enter the filling drive mechanism after passing through the pipeline switching mechanism 3.

[0062] Referring to Figures 3, 8, and 9, the motor synchronous belt linear module 130 includes a servo motor 131, a motor synchronous pulley 132 that rotates coaxially with the motor shaft of the servo motor 131, and two sets of spaced-apart rotating shaft synchronous pulley assemblies 133. The motor synchronous pulley 132 and one set of rotating shaft synchronous pulley assemblies 133 are connected and rotate synchronously via a primary synchronous belt 134, and the two sets of rotating shaft synchronous pulley assemblies 133 are connected and rotate synchronously via a secondary synchronous belt 135. A synchronous belt pressure plate 136 is provided at the bottom of the sliding mounting base 123 and is connected to the secondary synchronous belt 135 to achieve synchronous linkage. Two sets of parallel first linear guide rails 137 are provided below the sliding mounting base 123, and the sliding mounting base 123 is slidably connected to the first linear guide rails 137 via first guide rail sliders 138. The servo motor 131 drives the synchronous pulley 132 to rotate, which is transmitted through the primary synchronous belt 134 and the secondary synchronous belt 135, thereby driving the sliding mounting base 123 to move with the secondary synchronous belt 135, thereby adjusting the position of the ball-feeding mechanism 120.

[0063] Referring to Figures 2, 6, and 9, the air blowing mechanism 2 includes a pneumatic solenoid valve island 210. The pneumatic solenoid valve island 210 is connected to the inner cavity of each steel ball feeding plate 115 via several pipes, allowing for individual air blowing into the inner cavity of each steel ball feeding plate 115 to control the sliding of the steel balls in each pipe. A set of annular sensor assemblies 220 is installed below each steel ball feeding plate 115. The connecting pipe between the steel ball feeding plate 115 and the pipe switching mechanism 3 passes through the annular sensor assembly 220, used to detect whether the steel balls are falling normally and to output the specific pipe position and number of steel balls. When a steel ball in a certain pipe fails to fall, the annular sensor assembly 220 feeds the monitoring data back to the control backend, activating the vertical drive cylinder 1211 to drive the upper and lower vibrating plates 1212 to vibrate and cause the steel ball to fall. It also individually activates the pusher cylinder 1221 of that pipe to push the steel ball pusher rod 114 to deliver the steel ball to the steel ball feeding plate 115.

[0064] Referring to Figures 2 and 10, the pipeline switching mechanism 3 includes a fixed pipeline array 310, a linear motor module 320, and a movable pipeline array 330 arranged in parallel. The fixed pipeline array 310 is connected sequentially to each steel ball feeding plate 115 via pipelines, and the movable pipeline array 330 is connected sequentially to the air pipe connector 427 on the filling drive mechanism 420 via pipelines. Driven by the linear motor module 320, the movable pipeline array 330 moves along the arrangement direction of the fixed pipeline array 310 and docks with the designated pipeline interface on the fixed pipeline array 310 to form a closed airflow channel to facilitate the sliding of the steel balls. According to the specific dimensions of the steel ball groove 510 inside the tooling slider 5 of the steel ball to be filled, the movable pipeline array 330 connects to the pipeline interface on the fixed pipeline array 310 where the steel ball with the corresponding tolerance specification is located, and pushes the steel ball to the filling drive mechanism 4 via airflow.

[0065] Referring to Figures 11 and 12, the linear cylinder module 410 includes a rodless cylinder 411, two parallel second linear guide rails 412, second guide rail sliders 413, and a tooling limit seat 414. At least two second guide rail sliders 413 are fixed to the bottom of the tooling limit seat 414. The second guide rail sliders 413 are slidably connected to the second linear guide rails 412. Driven by the rodless cylinder 411, the tooling limit seat 414 moves the tooling slider 5 along the second linear guide rails 412 to the designated filling position. An adjustable transport lock 415 is also connected to the tooling limit seat 414. After the tooling slider 5 is installed on the tooling limit seat 414, the transport lock 415 is inserted into the end of the tooling slider 5 to fix its installation position, thereby improving the accuracy of filling steel balls.

[0066] Referring to Figures 11 and 13, the filling drive mechanism 420 includes two filling drive cylinders 421, two parallel third linear guide rails 422, and a third guide rail slider 423 slidably connected to the third linear guide rails 422. Each filling drive cylinder 421 is connected to a material channel seat 424, and each material channel seat 424 has a steel ball filling channel 425 fixed on it. The front end of each steel ball filling channel 425 is connected to a material channel head 426. The filling drive cylinder 421 drives the material channel seat 424 to slide along the third linear guide rail 422, inserting the material channel head 426 into the tooling slider 5. The rear end of each steel ball filling channel 423 is connected to the movable pipeline row 330 through two air pipe joints 427. The steel balls are propelled by airflow from the moving pipeline outlet 330 into the two air pipe joints 427, and under the action of the push rod drive mechanism 430, they enter the steel ball channel inside the steel ball filling channel 425 and the material channel head 426 in two separate paths, and finally enter the steel ball groove 510 inside the tooling slider 5.

[0067] Referring to Figures 11 and 14, the push rod drive mechanism 430 includes a push rod drive motor 431, a ball screw assembly 432, a slider connecting seat 433, and four long ball push rods 434. The push rod drive motor 431 is connected to the ball screw assembly 432 via a synchronous belt assembly 435 and rotates synchronously. The slider connecting seat 433 is threaded onto the outside of the ball screw assembly 432. The length direction of the long ball push rods 434 is consistent with the length direction of the ball screw assembly 432, and the rear end of the long ball push rods 434 is fixedly connected to the slider connecting seat 433. Under the driving action of the push rod drive motor 431, the slider connecting seat 433 moves along the ball screw assembly 432, simultaneously driving the long ball push rods 434 to be sequentially inserted into the ball channels inside the ball filling channel 425 and the channel head 426, pushing the balls into the ball grooves 510 inside the tooling slider 5. The push rod drive motor 431 uses a servo motor, which can better monitor the torque changes during the filling process, thereby identifying abnormalities in the process and providing alarm prompts.

[0068] In this invention, the internal steel ball channels of the steel ball filling channels 425 located on both sides of the filling drive mechanism 4 are in different positions, located on the upper and lower sides respectively. The material channel head 426 located on the same side is coaxial with the internal steel ball channel of the steel ball filling channel 425. After the steel ball filling channel 425 on one side is filled with steel balls, the push rod drive motor 431 drives the long push rod 434 of the steel ball to move backward (away from the tooling slider 5) and exit. At the same time, the filling drive cylinder 421 drives the material channel seat 424, the steel ball filling channel 425 and the material channel head 426 to slide backward and disengage from the tooling slider 5 along the third linear guide rail 422. Then, the rodless cylinder 411 drives the tooling limit seat 414 to move the tooling slider 5 along the second linear guide rail 412 to the other side of the filling. Position, the filling drive cylinder 421 drives the material channel seat 424, the steel ball filling channel 425 and the material channel head 426 to move forward along the third linear guide rail 422 into the tooling slider 5. The push rod drive motor 431 drives the steel ball long push rod 434 to extend forward into the steel ball channel inside the steel ball filling channel 425 and the material channel head 426, pushing the steel balls in the material channel seat 424 into the steel ball groove 510 inside the tooling slider 5, completing the steel ball filling work of the four steel ball grooves inside the tooling slider.

[0069] Referring to Figure 15, the multi-channel ball bearing slider filling device of this utility model can also be equipped with an external frame. The external frame includes an upper frame 7 covering the ball bearing dispensing mechanism 1, a lower frame 8 located below the upper frame 7, a horizontal mounting platform 9 located between the upper frame 7 and the lower frame 8, and an inclined mounting platform 10 located above the horizontal mounting platform 9. The inclined mounting platform 10 and the horizontal mounting platform 9 have a certain angle. The upper frame 7 and the lower frame 8 can protect the equipment, provide an installation position, and ensure structural stability. The air blowing mechanism 2 and the pipeline switching mechanism 3 are installed inside the lower frame 8 and located below the horizontal mounting platform 9. The ball bearing filling mechanism 4 is installed on the inclined mounting platform 10, which facilitates the rolling of the ball bearings by gravity during filling and assists the long ball bearing pusher 434 in pushing the ball bearings during filling.
