Description

Technical Field

[0001] This invention relates to the field of steel ball assembly and feeding technology, specifically to an automated, efficient, quantitative steel ball feeding mechanism and method. Background Technology

[0002] A recirculating ball steering system typically includes components such as a steering screw, a steering nut, steel balls, and guide tubes. The steering screw and steering nut form mating inner and outer helical raceways, within which a certain number of steel balls are assembled. The two ends of the guide tube are connected to the helical raceways, allowing the steel balls to circulate between the raceways and the guide tube. The number of steel balls usually needs to be determined based on the product structure and assembly requirements; in steel ball assembly scenarios, there is often a need to quantitatively retrieve balls.

[0003] During the assembly of the recirculating ball steering gear, steel balls need to be loaded into the spiral raceway in a specified quantity. Currently, some assembly scenarios still use manual methods for retrieving and loading steel balls. Operators typically need to take a certain number of steel balls from the steel ball storage container and then load them into the corresponding raceway positions.

[0004] The aforementioned manual ball retrieval and loading methods are highly dependent on the operator's skill and attention. In actual operation, it is possible to retrieve too many, too few, or miss some balls, or the balls may not enter the intended circulation raceway position. These situations increase the workload of subsequent inspection and adjustments and negatively impact the consistency of the assembly process.

[0005] In the prior art, there are already devices for quantitatively feeding steel balls or steel beads. For example, document number CN203781378U discloses a steel ball quantitative feeding device, which uses a hopper, feeding plate, cylinder, storage tank, discharge port and bottom plate through hole to allow steel balls to enter the feeding plate from the hopper and then be pushed out by the cylinder; document number CN210655333U discloses an automatic steel ball feeding device, which adopts a hopper, slide rail, slider, cylinder and through hole structure, and the cylinder drives the slider to move, so that the steel balls fall through the through hole; document number CN214242941U discloses a steel ball quantitative conveying device, which is equipped with a hopper, ball picking mechanism, support plate and ball distribution plate, and has a feed hole, discharge hole and feeding channel in the ball picking mechanism to realize the quantitative conveying of steel balls. The above-mentioned solutions can all replace manual ball handling to a certain extent, realizing the automatic supply or quantitative feeding of steel balls or beads. However, the solutions disclosed in the above literature mainly achieve quantitative supply of steel balls or beads through feeding plates, sliders, through holes, storage tanks, or feeding channels. Their structural focus is on the transfer of steel balls from the hopper to the discharge position. For scenarios such as circulating ball deflectors that require quantitative ball handling before assembly, followed by transfer of steel balls to the receiving position and centralized release, the above solutions still have certain limitations: on the one hand, the hopper discharge port needs to be reliably closed when not handling steel balls to reduce the continued fall of steel balls after the handling component exits; on the other hand, the handling component needs to stably support the steel balls that have been handled during the transfer process and release them uniformly after reaching the receiving position. Existing solutions are generally not specifically designed for the continuous action process of "normally closed discharge port - quantitative temporary storage - transfer support - fixed-point release," so there is still room for further improvement in this type of pre-assembly quantitative ball handling scenario.

[0006] Therefore, in scenarios such as recirculating ball steering systems where steel balls need to be assembled in a quantitative manner, it is still necessary to provide a mechanism and method that can quantitatively remove, temporarily store, transfer and release steel balls before assembly, so that steel balls can be removed and transferred to the receiving position in a predetermined quantity, thereby reducing the quantity error caused by manual counting and manual ball removal, and facilitating subsequent assembly operations. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the defects of the existing manual steel ball retrieval method, which has poor consistency in the number of balls retrieved, is prone to over-retrieval or under-retrieval, and is not convenient for automation. The present invention provides an automated, efficient, quantitative steel ball retrieval mechanism and method, which can quantitatively receive steel balls through a steel ball receiving plate and realize the temporary storage, transfer and release of steel balls through a steel ball receiving baffle, so that steel balls are retrieved and transported to the receiving position in a predetermined quantity, which can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automated and efficient quantitative steel ball retrieving mechanism and method, comprising a steel ball storage box assembly, a steel ball retrieving plate, a steel ball retrieving baffle, a dual-axis cylinder, a dual-axis cylinder fixing plate, a cylinder transition plate, a slide cylinder, a slide cylinder fixing plate, and a steel ball receiving box. The steel ball storage box assembly includes a steel ball box, a discharge baffle, a spring, an inclined plate, a guide rod, a square hole, and a support lug. The steel ball box is used to store steel balls, the square hole is located on one side of the bottom of the steel ball box, and the inclined plate is located inside the steel ball box and is used to guide the steel balls to the square hole. Specifically, the inclined plate... A plate is installed around the square hole to guide the steel balls in the ball box. Lugs are fixed to the bottom of the ball box. One end of a guide rod passes through the lug and is fixedly connected to the bent edge of one end of the discharge baffle. A spring is sleeved on the guide rod, with both ends abutting between the bent edge and the lug. The spring acts on the discharge baffle, causing it to close the square hole in a free state. A slide cylinder is mounted on a slide cylinder fixing plate, and a cylinder transition plate is connected to the moving parts of the slide cylinder. A predetermined number of holes are provided on the steel ball receiving plate to accommodate the steel balls. A dual-axis cylinder is fixed. A material-blocking channel is formed between the plate and the cylinder transition plate. The dual-axis cylinder fixing plate and the cylinder transition plate are spaced apart and relatively fixed. The steel ball picking baffle passes through the material-blocking channel and extends to the lower surface of the steel ball picking plate. The steel ball picking plate is connected to the dual-axis cylinder fixing plate and corresponds to the square hole. The steel ball picking plate can move closer to or away from the steel ball storage box assembly under the drive of the slide cylinder. One end of the steel ball picking baffle is connected to the telescopic end of the dual-axis cylinder. The dual-axis cylinder is installed on the dual-axis cylinder fixing plate and is used to drive the steel ball picking baffle relative to the steel ball picking plate. The plate moves to selectively close or open the bottom of the hole; when the steel ball picking plate moves to the bottom of the steel ball box, the steel ball picking plate pushes the feeding baffle, causing the feeding baffle to move the guide rod relative to the support lug and compress the spring, thereby opening the square hole, and the steel ball falls into the hole of the steel ball picking plate through the square hole; after the steel ball picking plate exits the bottom of the steel ball box, the feeding baffle is reset under the action of the spring and closes the square hole; after the steel ball picking plate moves to the top of the steel ball receiving box, the dual-axis cylinder drives the steel ball picking baffle to open the bottom of the hole, so that the steel ball in the hole falls into the steel ball receiving box.

[0009] Furthermore, the number of holes corresponds to the number of steel balls that need to be removed in a single operation.

[0010] Furthermore, the steel ball receiving plate is provided with bosses, which are located between adjacent holes and are used to separate and guide the steel balls; the holes are arranged in an array, and the bosses are arranged along the arrangement direction of the holes.

[0011] Furthermore, the lower surface of the steel ball receiving plate is provided with a groove, and the steel ball receiving baffle extends into the groove and can move along the groove to close or open the bottom of the hole.

[0012] Furthermore, the guide rod is slidable relative to the lug, which guides the direction of movement of the guide rod.

[0013] Furthermore, as the steel ball receiving plate approaches the steel ball storage box assembly, it abuts against the bent edge of the discharge baffle and pushes the discharge baffle from the closed position of the closed square hole to the open position of the open square hole.

[0014] Furthermore, the steel ball receiving box is provided with an inclined discharge port, which is used to discharge the steel balls that fall into the steel ball receiving box.

[0015] Furthermore, the steel ball receiving plate is detachably connected to the dual-axis cylinder fixing plate, so as to adapt to different specifications of steel balls or different ball receiving quantities by replacing the steel ball receiving plates with different numbers or different sizes of holes; the diameter of the hole is larger than the diameter of the steel ball to be received, and the depth of the hole is set to be able to accommodate a single steel ball.

[0016] Furthermore, an automated and efficient method for quantitatively dispensing steel balls includes the following steps: S1. The feeding baffle closes the square hole at the bottom of the steel ball box under the action of the spring, and the steel ball picking baffle closes the bottom of the hole on the steel ball picking plate. S2. Drive the dual-axis cylinder fixing plate and the steel ball picking plate to move toward the steel ball storage box assembly via the slide table cylinder; S3. When the steel ball picking plate moves to the bottom of the steel ball box, the steel ball picking plate pushes the discharge baffle, which causes the discharge baffle to move the guide rod relative to the lug fixed at the bottom of the steel ball box and compress the spring sleeved on the guide rod, thereby opening the square hole. S4. The steel balls in the steel ball box are guided by the inclined plate and fall into the hole of the steel ball picking plate through the square hole. S5. Drive the steel ball picking plate out of the bottom of the steel ball box through the slide cylinder, so that the steel balls that have not entered the hole remain in the steel ball box, and reset the feeding baffle under the action of the spring to close the square hole. In step S5, during the process of the steel ball receiving plate retracting from the bottom of the steel ball box, the steel ball receiving baffle remains in a closed state at the bottom of the hole to support the steel ball in the hole; S6. The slide cylinder drives the steel ball picking plate to move above the steel ball receiving box; S7. Drive the steel ball receiving baffle from the bottom of the closed hole to the bottom of the open hole by the dual-axis cylinder, so that the steel balls in the hole fall into the steel ball receiving box. S8. After step S7, the steel balls are discharged through the inclined outlet of the steel ball receiving box to the subsequent assembly station, collection container or feeding channel. S9. After the steel ball in the hole falls into the steel ball receiving box, the dual-axis cylinder drives the steel ball picking baffle to reset and reseal the bottom of the hole. Then the slide cylinder drives the steel ball picking plate to enter the next picking cycle.

[0017] Furthermore, in step S4, the number of steel balls falling into the holes at a time is limited by a predetermined number of holes on the steel ball receiving plate; the steel balls are separated and guided by the bosses set between adjacent holes, so that the steel balls enter the corresponding holes.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. Compared with the manual method of taking steel balls, the present invention sets a predetermined number of holes on the steel ball taking plate, so that the number of steel balls taken out at one time is limited by the number of holes, thereby reducing the possibility of taking too many, too few or missing steel balls during the manual counting process, which is conducive to improving the consistency of the number of steel balls taken out; this effect corresponds to the technical problem of the risk of taking too many or missing steel balls when taking them manually.

[0019] 2. This invention features a discharge baffle at the bottom of the steel ball box, with a spring ensuring the baffle closes the discharge opening in a free state, keeping the steel ball box closed when not in a discharging state. During discharging, a steel ball discharging plate pushes the discharge baffle to open the discharge opening; after discharging and withdrawal, the discharge baffle resets under spring pressure and recloses the discharge opening. This reduces the likelihood of steel balls continuing to fall when not in a discharging state, improving the controllability of the steel ball discharging process.

[0020] 3. This invention controls the sealing and opening of the bottom of the holes in the steel ball receiving plate using a steel ball receiving baffle. During the receiving and transfer process, the steel ball receiving baffle seals the bottom of the holes to support the steel balls that have entered the holes. When the steel ball receiving plate moves to the receiving position, the steel ball receiving baffle opens the bottom of the holes, allowing the steel balls to fall into the receiving box. Thus, this invention can achieve quantitative temporary storage, transfer support, and fixed-point release of steel balls, facilitating connection with subsequent assembly processes.

[0021] 4. The present invention also guides the steel balls to the feeding port through the inclined plate, and separates and guides the steel balls through the protrusions between adjacent holes, making it easier for the steel balls to enter the corresponding holes and reducing the impact of the accumulation or displacement of steel balls in the feeding area on the feeding process. Overall, the present invention can complete the automatic quantitative extraction, transfer and release of steel balls with a relatively simple structure, which is conducive to improving the consistency and automation of the steel ball feeding process.

Example 1

[0025] Please see Figure 1-4 This invention provides a technical solution: an automated and efficient quantitative steel ball retrieving mechanism and method, comprising a steel ball storage box assembly 101, a steel ball retrieving plate 102, a steel ball retrieving baffle 103, a dual-axis cylinder 104, a dual-axis cylinder fixing plate 105, a cylinder transition plate 106, a sliding table cylinder 107, a sliding table cylinder fixing plate 108, and a steel ball receiving box 109; the sliding table cylinder 107 is mounted on the sliding table cylinder fixing plate 108, and the cylinder transition plate 106 is connected to the moving parts of the sliding table cylinder 107, so that the cylinder transition plate 106 can move on the sliding table cylinder. Driven by cylinder 107, it performs linear reciprocating motion; the dual-axis cylinder fixing plate 105 and cylinder transition plate 106 are spaced apart and fixed relative to each other, and the steel ball picking plate 102 is connected to the dual-axis cylinder fixing plate 105, so that the steel ball picking plate 102, the dual-axis cylinder fixing plate 105 and the cylinder transition plate 106 can synchronously approach or move away from the steel ball storage box assembly 101 under the drive of the slide cylinder 107; the position of the steel ball picking plate 102 corresponds to the square hole 115 at the bottom of the steel ball storage box assembly 101, and is used to receive the steel balls falling from the square hole 115 when picking up materials.

[0026] The steel ball storage box assembly 101 includes a steel ball box 110, a discharge baffle 111, a spring 112, an inclined plate 113, a guide rod 114, a square hole 115, and a support lug 116. The steel ball box 110 is used to store steel balls to be taken out. The square hole 115 is located on one side of the bottom of the steel ball box 110 and serves as the discharge port for the steel balls to fall from the steel ball box 110. The inclined plate 113 is located inside the steel ball box 110, preferably installed around the square hole 115, to guide the steel balls inside the steel ball box 110 to the square hole 115, so that the steel balls can gather at the square hole 115 under the action of gravity. The support lug 116 is used for fixing. At the bottom of the steel ball box 110, one end of the guide rod 114 passes through the lug 116 and is fixedly connected to the bent edge 120 at one end of the discharge baffle 111. The spring 112 is sleeved on the guide rod 114, and the two ends of the spring 112 abut against the bent edge 120 and the lug 116 respectively. The discharge baffle 111 can move relative to the lug 116 under the guidance of the guide rod 114. In the free state, the spring 112 acts on the discharge baffle 111, so that the discharge baffle 111 is in the position of closing the square hole 115, thereby preventing the steel balls in the steel ball box 110 from continuing to fall from the square hole 115.

[0027] The steel ball receiving plate 102 is provided with a predetermined number of holes 118 for accommodating steel balls. The number of holes 118 is determined according to the number of steel balls to be retrieved in a single operation, enabling the steel ball receiving plate 102 to quantitatively retrieve balls through the holes 118. Preferably, the diameter of the holes 118 is larger than the diameter of the steel balls to be retrieved, and the depth of the holes 118 is set to accommodate a single steel ball, so that each hole 118 corresponds to one steel ball. Multiple holes 118 can be arranged in an array. The steel ball receiving plate 102 is also provided with bosses 117, which are located between adjacent holes 118 and arranged along the arrangement direction of the holes 118. The bosses 117 are used to separate and guide the steel balls, so that the steel balls can smoothly enter the corresponding holes 118 after falling from the square holes 115, reducing the impact of steel balls accumulating or shifting between the holes 118 on the retrieving process.

[0028] A dual-axis cylinder 104 is mounted on a dual-axis cylinder fixing plate 105. The left end of the steel ball picking baffle 103 is connected to the telescopic end of the dual-axis cylinder 104. A material-blocking channel 121 is formed between the dual-axis cylinder fixing plate 105 and the cylinder transition plate 106. The steel ball picking baffle 103 passes through the material-blocking channel 121 and extends to the lower surface of the steel ball picking plate 102. Preferably, a groove is provided on the lower surface of the steel ball picking plate 102, and the steel ball picking baffle 103 extends into the groove and can move along the groove relative to the material-blocking plate 102. The steel ball receiving plate 102 moves; the dual-axis cylinder 104 drives the steel ball receiving baffle 103 to move between a closed position and an open position; when the steel ball receiving baffle 103 is in the closed position, the steel ball receiving baffle 103 blocks the bottom of the hole 118, so that the steel ball entering the hole 118 is supported in the steel ball receiving plate 102; when the steel ball receiving baffle 103 is in the open position, the bottom of the hole 118 is opened, and the steel ball in the hole 118 can fall downward under the action of gravity.

[0029] The steel ball receiving box 109 is located below the position where the steel ball is released from the steel ball receiving plate 102, and is used to receive the steel balls falling from the hole 118. The steel ball receiving box 109 is provided with an inclined discharge port 119, which is used to guide the steel balls falling into the steel ball receiving box 109 to the subsequent assembly station, collection container or feeding channel. The inclination direction and outlet position of the inclined discharge port 119 can be set according to the position of the subsequent assembly equipment so that the steel balls can be smoothly discharged after falling into the steel ball receiving box 109.

[0030] The working process of this embodiment is as follows.

[0031] In the initial state, the feeding baffle 111 closes the square hole 115 at the bottom of the steel ball box 110 under the action of the spring 112, and the steel balls in the steel ball box 110 are confined inside the steel ball box 110; at the same time, the dual-axis cylinder 104 puts the steel ball picking baffle 103 in the closed position, and the steel ball picking baffle 103 blocks the bottom of the hole 118 on the steel ball picking plate 102; at this time, the slide cylinder 107 is in the ready-to-pick-up state, and the steel ball picking plate 102 is located outside the steel ball storage box assembly 101 or away from the square hole 115.

[0032] During material handling, the slide cylinder 107 actuates, driving the cylinder transition plate 106, the dual-axis cylinder fixing plate 105, and the steel ball picking plate 102 to move towards the steel ball storage box assembly 101. When the steel ball picking plate 102 moves to the bottom of the steel ball box 110, the steel ball picking plate 102 abuts against the bent edge 120 of the discharge baffle 111 or the corresponding force-bearing part of the discharge baffle 111, and pushes the discharge baffle 111 to move. The discharge baffle 111 drives the guide rod 114 to slide relative to the lug 116, and at the same time compresses the spring 112 sleeved on the guide rod 114, so that the discharge baffle 111 moves from the closed position of the closed square hole 115 to the open position of the open square hole 115.

[0033] After the square hole 115 is opened, the steel balls in the steel ball box 110 gather towards the square hole 115 under the guidance of the inclined plate 113, and fall into the hole 118 of the steel ball picking plate 102 through the square hole 115. Since the number of holes 118 is predetermined, the number of steel balls falling into the holes 118 corresponds to the number of holes 118. The boss 117 located between adjacent holes 118 plays a role in separating and guiding the steel balls, so that the steel balls enter the corresponding holes 118.

[0034] After the steel ball enters the hole 118, the slide cylinder 107 reverses its movement, causing the steel ball picking plate 102 to exit the bottom of the steel ball box 110. During the exit of the steel ball picking plate 102, the steel ball picking baffle 103 remains in a closed state at the bottom of the hole 118, supporting the steel ball in the hole 118, so that the steel ball that has entered the hole 118 moves together with the steel ball picking plate 102. The steel ball that has not entered the hole 118 is blocked by the bottom structure of the steel ball box 110 or the surrounding structure of the square hole 115 and remains in the steel ball box 110. After the steel ball picking plate 102 exits, the discharge baffle 111 moves and resets under the restoring force of the spring 112, and re-closes the square hole 115, so that the steel ball box 110 returns to the non-picking state.

[0035] When the slide cylinder 107 moves the steel ball picking plate 102 above the steel ball receiving box 109, the dual-axis cylinder 104 actuates, driving the steel ball picking baffle 103 from the position of the closed hole 118 bottom to the position of the open hole 118 bottom; at this time, the steel ball in the hole 118 falls into the steel ball receiving box 109 under the action of gravity, and is discharged through the inclined discharge port 119 to the subsequent assembly station, collection container or feeding channel; after the steel ball falls out, the dual-axis cylinder 104 drives the steel ball picking baffle 103 to reset, so that the steel ball picking baffle 103 re-closes the bottom of the hole 118; then, the slide cylinder 107 can drive the steel ball picking plate 102 to move towards the steel ball storage box assembly 101 again to enter the next picking cycle.

[0036] In this embodiment, the number of holes 118 on the steel ball receiving plate 102 can be set according to the actual number of steel balls required for assembly. For example, when a number of steel balls need to be taken out in a single assembly, the same number of holes 118 can be set on the steel ball receiving plate 102. The steel ball receiving plate 102 can be detachably connected to the dual-axis cylinder fixing plate 105. When it is necessary to adapt to different models of products, steel balls of different diameters, or different numbers of balls to be taken out, steel ball receiving plates 102 with different hole diameters, hole depths, or number of holes can be replaced.

[0037] In other embodiments, the slide cylinder 107 can be replaced by an electric slide, a linear module, or other drive mechanism capable of driving the steel ball receiving plate 102 to perform linear reciprocating motion; the dual-axis cylinder 104 can be replaced by a single-axis cylinder, an electric push rod, or other drive mechanism capable of driving the steel ball receiving baffle 103 to move; the spring 112 can be replaced by other elastic elements capable of resetting the discharge baffle 111; the above replacements can all be optional embodiments of the present invention as long as they can realize the action process of the steel ball receiving plate 102 opening the square hole 115, the hole 118 quantitatively receiving the steel ball, and the steel ball receiving baffle 103 supporting and releasing the steel ball.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of the present invention as claimed.

The automated, efficient, quantitative steel ball dispensing mechanism according to claim 1, characterized in that: The steel ball receiving plate (102) is detachably connected to the dual-axis cylinder fixing plate (105) so as to adapt to different specifications of steel balls or different number of balls to be received by replacing the steel ball receiving plate (102) with different numbers or different sizes of holes (118); the diameter of the hole (118) is larger than the diameter of the steel ball to be received, and the depth of the hole (118) is set to be able to accommodate a single steel ball.

9. A method for automated, efficient, and quantitatively dispensing of steel balls, characterized in that, The automated and efficient quantitative steel ball dispensing mechanism according to any one of claims 1 to 8 includes the following steps: S1. The feeding baffle (111) closes the square hole (115) at the bottom of the steel ball box (110) under the action of the spring (112), and the steel ball picking baffle (103) closes the bottom of the hole (118) on the steel ball picking plate (102); S2. Drive the dual-axis cylinder fixing plate (105) and the steel ball picking plate (102) towards the steel ball storage box assembly (101) by the slide cylinder (107); S3. When the steel ball picking plate (102) moves to the bottom of the steel ball box (110), the steel ball picking plate (102) pushes the discharge baffle (111), causing the discharge baffle (111) to drive the guide rod (114) to move relative to the lug (116) fixed at the bottom of the steel ball box (110), and compress the spring (112) sleeved on the guide rod (114), thereby opening the square hole (115). S4. The steel balls in the steel ball box (110) are guided by the inclined plate (113) and fall into the hole (118) of the steel ball picking plate (102) through the square hole (115); S5. Drive the steel ball picking plate (102) out of the bottom of the steel ball box (110) by the slide cylinder (107), so that the steel balls that have not entered the hole (118) remain in the steel ball box (110), and the feeding baffle (111) is reset and closed by the action of the spring (112) to close the square hole (115). S6. The slide cylinder (107) drives the steel ball picking plate (102) to move above the steel ball receiving box (109); S7. Drive the steel ball receiving baffle (103) from the bottom of the closed hole (118) to the bottom of the open hole (118) by the dual-axis cylinder (104), so that the steel ball in the hole (118) falls into the steel ball receiving box (109). S8. After step S7, the steel ball is discharged through the inclined outlet (119) of the steel ball receiving box (109) to the subsequent assembly station, collection container or feeding channel. S9. After the steel ball in the hole (118) falls into the steel ball receiving box (109), the dual-axis cylinder (104) drives the steel ball picking baffle (103) to reset and re-close the bottom of the hole (118). Then the slide cylinder (107) drives the steel ball picking plate (102) to enter the next picking cycle.

10. The method according to claim 9, characterized in that: In step S4, the number of steel balls falling into the holes (118) at a time is limited by a predetermined number of holes (118) on the steel ball receiving plate (102); the steel balls are separated and guided by the bosses (117) set between adjacent holes (118) so that the steel balls enter the corresponding holes (118).
