Description

Technical Field

[0001] This invention belongs to the field of constant velocity drive shaft assembly technology, specifically relating to a steel ball assembly error prevention device. Background Technology

[0002] Currently, the assembly process for the fixed section of the constant velocity drive shaft requires assembling the outer star wheel, ball cage, inner star wheel, and steel balls into a component. Depending on the number of ball channels in different section types, each section generally requires 6 or 8 steel balls; because the ball channel dimensions vary for different section types, there are various specifications of steel balls; in order to meet product performance requirements, the steel balls required by the product must be used during the assembly of the fixed section.

[0003] Currently, in the field of constant velocity drive shaft assembly, the assembly of the fixed section is generally done manually, with workers manually handling parts such as steel balls and assembling them into components. Because it is a manual operation, there is a risk of incorrect or missing steel balls during the assembly process.

[0004] Authorization announcement number: CN219119667U, discloses a special device for conveying steel balls in a bearing assembly machine, which solves the problem that existing bearing assembly machines cannot count the number of steel balls required for different bearings. The conveyor belt is used to transport the outer ring and inner ring of the bearing. Under the action of the counting sensor, the steel balls entering the counting funnel can be counted. When the number of steel balls reaches a specified number, the ball outlet of the conveying pipe can be sealed under the action of the sealing mechanism. Then, under the action of the ball conveying pipe, the steel balls are transported to the steel ball assembly head. The steel ball assembly head can then assemble the steel balls between the outer ring and the inner ring of the bearing. Thus, the bearing assembly machine can count the number of steel balls required for different bearings, which is convenient to use.

[0005] Authorization announcement number: CN108518423B, discloses a semi-automatic steel ball assembly machine, which solves the problem that steel balls are manually loaded into the retainer. By placing the retainer on the top of the inner mold, the steel balls can be automatically assembled into the retainer.

[0006] The existing technology described above does not provide technical measures for effective steel ball size selection and quantitative input in the steel ball assembly of the constant velocity drive shaft fixed section, therefore, it needs to be improved. Summary of the Invention

[0007] In view of this, and in response to the shortcomings of the existing technology, the purpose of this invention is to provide a steel ball assembly error prevention device, so as to achieve the size screening of steel ball materials, the counting and quantitative feeding of steel ball materials into the assembly process, and the counting to meet the assembly requirements, and the torque measurement on the worktable after the assembly is completed.

[0008] To achieve the above and other related objectives, the present invention provides a steel ball assembly error prevention device, including a feeding mechanism, a steel ball screening mechanism, a quantitative discharging mechanism, and a frame. The feeding mechanism is used to input materials into the steel ball screening mechanism, the steel ball screening mechanism is used to screen materials of a target size, the materials output by the steel ball screening mechanism are sent to the quantitative discharging mechanism, and the quantitative discharging mechanism outputs materials in a target quantity.

[0009] The feeding mechanism includes a hopper and an automatic feeding device. The automatic feeding device includes a feeding track and a telescopic device. The telescopic device drives the feeding track to pick up the material from the bottom of the hopper and send it into the steel ball screening mechanism. The feeding track is sloped so that the material tends to move towards the lower end of the feeding track under the action of gravity.

[0010] A baffle is connected to the lower end of the material picking track. A material inlet is set at the upper limit position of the material picking track, so that the material can slide into the screening track of the steel ball screening mechanism through the material inlet. The screening track is sloped so that the material slides unidirectionally along the screening track under the action of gravity.

[0011] The screening track is equipped with a small ball channel, a qualified channel, and a large ball channel in sequence along the material movement direction. Materials of the target size enter the qualified channel, materials larger than the target size enter the large ball channel, and materials smaller than the target size enter the small ball channel.

[0012] The technical solution provided in this application also has the following technical features:

[0013] Preferably, the qualified channel of the steel ball screening mechanism is connected to the inlet end of the quantitative discharge mechanism. The quantitative discharge mechanism includes a dropping device and a picking device. The dropping device includes an inlet end, a dropping cylinder, a dropping channel, a counting sensor, and a quantitative dividing device. The discharge end of the dropping device is connected to the picking device. The dropping device is connected to the inlet end through the quantitative dividing device, and a buffer full sensor is set at the connection. The quantitative dividing device includes a buffer material ramp and an adjustable baffle. The material in the buffer material ramp is tightly arranged under the action of gravity. The adjustable baffle is used to block part of the material stored in the quantitative dividing device to obtain the target quantity of material. The target quantity of material is sent into the picking device through the dropping channel, and a counting sensor is set at the entrance of the dropping channel. The dropping cylinder is used to control the opening and closing of the entrance of the dropping channel. A picking sensor is set at the entrance of the picking device.

[0014] Preferably, a feeding cylinder is provided on the feeding device. The feeding cylinder drives the baffle to be placed into the quantitative dividing device, so that the single material stored in the quantitative dividing device is fed out for feeding.

[0015] Preferably, the material handling device includes a material handling sensor and a material handling box.

[0016] Preferably, an upper guide pusher limiting plate is provided above the upper limit position of the automatic pusher device, and the upper guide pusher limiting plate is used to limit the jumping of the material on the automatic pusher device.

[0017] Preferably, a workbench is provided on the frame, and a material handling device and a torque detection mechanism are provided on the workbench.

[0018] Preferably, the torque detection mechanism includes a rocker handle, a rocker handle base, a torque sensor, and a clamping sleeve mechanism. After the torque detection mechanism detects that the rocker handle has been removed, the clamping sleeve mechanism automatically clamps the workpiece. After the torque sensor detects that the torque of the fixed section is qualified, and the rocker handle base is returned to the positioning seat, the clamping sleeve mechanism automatically opens.

[0019] Preferably, the material channel between the steel ball screening mechanism and the quantitative discharge mechanism is an arc-shaped circular tube channel, and the material slides from the outlet of the steel ball screening mechanism to the inlet of the quantitative discharge mechanism under the action of gravity.

[0020] Preferably, the material channel between the quantitative discharge mechanism and the torque detection mechanism is an arc-shaped circular tube channel, and the material slides from the outlet of the quantitative discharge mechanism to the inlet of the torque detection mechanism under the action of gravity.

[0021] Preferably, the silo is equipped with a silo door sensor and a silo level sensor. The silo level sensor is used to determine the silo level, and the silo door sensor is used to determine the opening and closing status of the silo door.

[0022] Preferably, the steel ball screening mechanism is equipped with a tooling model sensor for measuring the target tooling of the target material.

[0023] Preferably, the feeding mechanism also includes sensor accessories; the hopper of this application takes into account the prevention of human error and is designed as a closed type. The hopper is equipped with a door sensor, that is, a sensing element is installed at the hopper door. When the hopper door is opened, the equipment will issue an alarm prompt.

[0024] The hopper is equipped with a photoelectric sensor at the bottom. When there are not enough steel balls at the lowest point of the hopper, the equipment will issue a warning that the hopper is low on material. The hopper can hold 800 steel balls at a time, reducing the number of times it needs to be refilled.

[0025] In the automatic feeding device, the telescopic device is a cylinder that can be lifted up and down, and the feeding track is a top plate with grooves. The steel balls are automatically pushed out of the hopper by the reciprocating lifting of the cylinder.

[0026] After the steel balls are pushed out of the hopper, they are sent to the steel ball screening mechanism; the steel ball screening mechanism can quickly change the tooling according to the specifications of the steel balls; the tooling model sensor is set to prevent incorrect tooling model. If the model is incorrect, the equipment will alarm and cannot start.

[0027] The tooling's error-proof structure is a three-channel variable diameter design, which can reject large and small steel balls into the non-conforming product channel, while the correct size steel balls enter the quantitative discharge mechanism through the qualified product channel for buffering.

[0028] The buffer channel of the quantitative discharge mechanism is equipped with a buffer full sensor that is linked to the feeding mechanism. When the buffer channel is full, the discharge mechanism stops pushing the material.

[0029] The quantitative discharge mechanism consists of a quantitative dividing device, a dropping device, and a picking device. The dividing device is designed to be adjustable to control the number of steel balls dropped, such as dropping 6 or 8 steel balls each time. After the dropping cylinder is lifted, the dropping channel is opened, and the quantitative steel balls enter the picking device through the dropping channel.

[0030] Considering that steel balls may fall due to improper operation during assembly, the device is designed with a feeding mechanism. By pressing the feeding button, the feeding cylinder is extended, which can realize the feeding action of a single steel ball.

[0031] At the material drop point, a counting sensor is designed. When the steel balls are not dropped in the target quantity, the equipment will issue an alarm.

[0032] The material handling device consists of a material handling box and a material handling sensor. By linking with the material dropping device, after triggering a material handling signal once in one assembly cycle, the material dropping device automatically triggers the next set of steel balls to drop.

[0033] If the steel ball picking action is not detected during the assembly process, the equipment will alarm and lock the workpiece through the clamping sleeve mechanism to avoid mixing unknown steel balls due to improper operation.

[0034] The torque detection mechanism includes a rocker handle, a rocker handle base, a torque sensor, and a clamping sleeve mechanism. A sensor is designed at the rocker handle base. When the rocker handle is detected to be removed, the clamping sleeve mechanism automatically clamps the workpiece. The tension and compression sensors of the torque sensor detect that the fixed section torque is qualified. After the rocker handle is returned to the positioning seat, the clamping sleeve mechanism releases the workpiece.

[0035] The beneficial effects of this invention are as follows:

[0036] This application realizes automatic error prevention for assembling steel balls in fixed sections, and reduces the quality risks caused by human error based on ergonomics.

[0037] This application integrates with the Manufacturing Execution System to monitor and collect process data, thereby improving the level of intelligent manufacturing.

[0038] This application uses quantitative steel ball dispensing, which makes material handling easier for personnel and reduces the cycle time of a single piece by 3-5 seconds.

[0039] The equipment design in this application meets the requirements of traditional assembly lines and is applicable to widespread use. Attached Figure Description

[0081] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0082] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0083] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0084] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0085] like Figure 1 and Figure 4 , Figure 9 A steel ball assembly error prevention device includes a feeding mechanism 1, a steel ball screening mechanism 2, a quantitative discharging mechanism 3, and a frame 5. The feeding mechanism 1 is used to input materials into the steel ball screening mechanism 2, the steel ball screening mechanism 2 is used to screen materials of the target size, and the materials output by the steel ball screening mechanism 2 are sent to the quantitative discharging mechanism 3, and the quantitative discharging mechanism 3 outputs materials in the target quantity.

[0086] like Figure 2 , Figure 7 The feeding mechanism 1 includes a hopper 11 and an automatic feeding device 13. The automatic feeding device 13 includes a feeding track and a telescopic device. The telescopic device drives the feeding track to pick up material from the bottom of the hopper 11 and send it into the steel ball screening mechanism 2. The feeding track is sloped so that the material tends to move towards the lower end of the feeding track under the action of gravity. Relying on this structure, continuous feeding is achieved, and the material is continuously sent from the hopper 11 into the steel ball screening mechanism 2.

[0087] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7The lower end of the material picking track is connected to a baffle. The baffle is set with a material inlet at the upper limit position of the material picking track, so that the material slides into the screening track of the steel ball screening mechanism 2 through the material inlet. The screening track is set with a slope so that the material slides unidirectionally along the screening track under the action of gravity. Relying on this structure, the material on the material picking track is limited by the lower section of the material inlet of the baffle. After the material reaches the material inlet, the material passes through the material inlet and slides into the screening track of the steel ball screening mechanism 2.

[0088] like Figure 2 , Figure 3 , Figure 4 , Figure 6 Along the material movement direction, the screening track is set with a small ball channel 23, a qualified channel 22, and a large ball channel 21. Materials of the target size enter the qualified channel 22, materials larger than the target size enter the large ball channel 21, and materials smaller than the target size enter the small ball channel 23. Based on this structure, materials of the target size are selected and materials of non-target size are rejected.

[0089] Specifically, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 The qualified channel 22 of the steel ball screening mechanism 2 is connected to the inlet end of the quantitative discharge mechanism 3. The quantitative discharge mechanism 3 includes a dropping device 30 and a picking device 37. The dropping device 30 includes an inlet end, a dropping cylinder 33, a dropping channel 34, a counting sensor 35, and a quantitative dividing device 36. The discharge end of the dropping device 30 is connected to the picking device 37. The dropping device 30 is connected to the inlet end through the quantitative dividing device 36, and a buffer full sensor 31 is set at the connection. The quantitative dividing device 36 includes a buffer material ramp and Adjustable baffle 361 buffers the material in the material ramp, causing the material to be tightly arranged under the action of gravity. Adjusting the position of adjustable baffle 361, i.e., inserting it into the quantitative dividing device 36, blocks the material on the infeeding side, while the material on the outfeeding side of adjustable baffle 361 is discharged smoothly. The adjustable baffle 361 inserts into the quantitative dividing device 36 through a cyclic up-and-down reciprocating motion, so that the material enters the quantitative dividing device 36 and the unblocked material inside the quantitative dividing device 36 is discharged.

[0090] Furthermore, the position of the adjustable baffle 361 of the quantitative dividing device 36 can be adjusted, that is, the adjustable baffle 361 can be adjusted to be inserted into the position of the quantitative dividing device 36 to realize the feeding of the target material and obtain the target quantity. Since the length of the same material is fixed, the target quantity of material can be obtained by controlling the position, that is, the length of the material to be released.

[0091] Specifically, this can be achieved by setting up a sliding pair with the reciprocating motion direction perpendicular to the center line of the material trajectory within the quantitative dividing device 36. Then, a lifting plate parallel to the center line of the material trajectory within the quantitative dividing device 36 is set on the sliding pair, and an adjustable baffle 361 is set along the lifting plate, so that the position of the baffle 361 inserted into the quantitative dividing device 36 can be adjusted.

[0092] like Figure 7 , 11 The adjustable baffle 361 is used to separate a portion of the material stored in the quantitative dividing device 36 to obtain the target quantity of material. The target quantity of material is fed into the picking device 37 through the dropping channel 34. A counting sensor 35 is installed at the entrance of the dropping channel 34, and a dropping cylinder 33 is used to control the opening and closing of the entrance of the dropping channel 34. A picking sensor 38 is installed at the entrance of the picking device 37. Based on this structure, the target quantity of material is taken out, and the adjustable baffle 361 is used to adjust the buffer material ramp to buffer the material storage position, so that the quantity of material to be discharged can be released.

[0093] The adjustable baffle 361 is continuously linked with the material discharge cylinder 33. That is, during the stroke of the material discharge cylinder 33, the adjustable baffle 361 first blocks part of the material from being discharged. The remaining material that can be discharged is controlled according to the length to obtain the target quantity of the bin. Then the material discharge cylinder 33 is started to start discharging, so that the material is discharged through the material outlet or hole.

[0094] Alternatively, an additional telescopic device can be set up to drive the adjustable baffle 361 to insert into the rolling trajectory of the material, blocking the material. After the material discharge cylinder 33 starts and completes the material discharge, the adjustable baffle 361 retracts in the next cycle, allowing the material to continuously enter the quantitative dividing device 36. By continuously working according to this cycle rhythm, the production requirements can be met.

[0095] The amount of material falling can be continuously controlled through the material drop channel 34, the counting sensor 35, and the material drop cylinder 33, thereby realizing another quantitative feeding and feeding device 37.

[0096] Specifically, such as Figure 4 , Figure 6 , Figure 8 , Figure 10 The feeding device 30 is equipped with a feeding cylinder 32, which is used to be placed into the quantitative dividing device 36 so that the quantitative dividing device 36 stores a single material for feeding; relying on this structure, the feeding of a single material can be realized.

[0097] Specifically, the material handling device 37 includes a material handling sensor 38 and a material handling box 39. Based on this structure, the target quantity of materials is counted and presented in the material handling box 39 in the target quantity, so that the assembly worker can meet the material handling requirements.

[0098] Specifically, such as Figure 10 An upper guide pusher limit plate 14 is provided above the upper limit position of the automatic pusher device 13. The upper guide pusher limit plate 14 is used to limit the jumping of the material on the automatic pusher device 13. With this structure, when the automatic pusher device 13 pushes the material, it avoids the problem that the material may jump up or fall off the picking track due to inertia when it stops at the upper limit position.

[0099] Specifically, such as Figure 1 , Figure 4 , Figure 10 A workbench is set on the frame 5, and a material handling device 37 and a torque detection mechanism 4 are set on the workbench. Based on this structure, the requirements for assembly and torque measurement are met.

[0100] Specifically, such as Figure 10 The torque detection mechanism 4 includes a rocker handle 41, a rocker handle base 42, a torque sensor 43, and a clamping sleeve mechanism 44. After the torque detection mechanism 4 detects that the rocker handle 41 has been removed from the rocker handle base 42, the clamping sleeve mechanism 44 automatically clamps the workpiece. The torque sensor 43 detects that the torque of the fixed section is qualified, and after the rocker handle base 42 is returned to the positioning seat, the clamping sleeve mechanism 44 automatically opens. The rocker handle 41 is removed from the rocker handle base 42 by the worker and inserted into the fixed section fixed on the clamping sleeve mechanism 44. It is manually rocked to complete the eccentricity detection. The manual operation is low-cost, easy to implement, and conforms to the assembly and inspection operation habits and operation sequence here.

[0101] Specifically, such as Figure 1 , Figure 4 The material channel between the steel ball screening mechanism 2 and the quantitative discharge mechanism 3 is an arc-shaped circular tube channel. Under the action of gravity, the material slides from the outlet of the steel ball screening mechanism 2 to the inlet of the quantitative discharge mechanism 3. Relying on this structure, the material is conveyed efficiently and there will be no loss, leakage or jamming of material. It is also convenient to lay out the conveying line.

[0102] Specifically, such as Figure 1 , Figure 4 The material channel between the quantitative discharge mechanism 3 and the torque detection mechanism 4 is an arc-shaped circular tube channel. Under the action of gravity, the material slides from the outlet of the quantitative discharge mechanism 3 to the inlet of the torque detection mechanism 4. Relying on this structure, the material is conveyed efficiently and there will be no loss, leakage or jamming of material. It is also convenient to lay out the conveying line.

[0103] Specifically, such as Figure 1The hopper 11 is equipped with a hopper door sensor 12 and a hopper position sensor 15. The hopper position sensor 15 is used to determine the hopper position of the hopper 11, and the hopper door sensor 12 is used to determine the opening and closing status of the hopper door of the hopper 11. This is conducive to the linkage with other structures to form a rhythmic production and smoothly connect the production needs of feeding, screening and quantitative discharge.

[0104] Specifically, such as Figure 2 , Figure 6 The steel ball screening mechanism 2 is equipped with a tooling model sensor 24, which is used to measure the target tooling of the target material. Based on this structure, the tooling is measured to match and detect whether the production requirements are consistent.

[0105] This application consists of a feeding mechanism 1, a steel ball screening mechanism 2, a quantitative discharging mechanism 3, and a torque detection mechanism 4. The feeding mechanism 1 is used to select materials and feed them into the steel ball screening mechanism 2. After screening, the steel ball screening mechanism 2 feeds the materials into the quantitative discharging mechanism 3. The quantitative discharging mechanism 3 assists workers in assembly by discharging materials in a quantitative manner and also monitors the process.

[0106] 1. Select the appropriate steel ball anti-misoperation tooling according to the product, and switch the formula to the product to be produced in the interface.

[0107] 2. Open the hopper door and pour the steel balls into the hopper;

[0108] 3. Start the equipment by clicking the manual trigger button; the automatic feeding mechanism will then start.

[0109] 4. When the material channel signal of the quantitative discharging mechanism is full, the automatic pushing mechanism stops. At this time, steel balls can be taken from the material box to start assembly.

[0110] 5. After the material feeding signal is triggered, the quantitative discharging structure automatically releases the next set of steel balls;

[0111] 6. At the end of the shift, the remaining steel balls can be automatically cleared using the "Clear Line" button;

[0112] This application can also automatically send the steel ball specifications from the product BOM in the production work order to the equipment and automatically verify the formula by interfacing with the manufacturing execution system. When the steel ball model in the formula is inconsistent with the steel ball model in the product BOM, the equipment will alarm and cannot start. The purpose of this design is to avoid batch errors caused by equipment formula errors and to achieve error prevention by using the intelligent manufacturing system.

[0113] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
