Description

Technical Field

[0001] The present invention relates to the technical field of Hall flowmeter assembly equipment, and in particular to a magnetic core assembly device and a corresponding use method. Background Art

[0002] The Hall flowmeter is a flow detection device based on a Hall sensor and uses displacement sensing. It includes an impeller and a Hall sensor inside, wherein a number of magnetic cores are evenly distributed on the impeller facing the Hall sensor. When the impeller is pushed and rotated by the fluid, it drives the magnetic core to move, thereby triggering the Hall sensor, allowing the Hall sensor to detect and obtain flow information. The magnetic core used in the Hall flowmeter is a cylindrical magnetic needle cut from a magnet. A slot that matches the magnetic core is opened on the impeller. The magnetic core can be inserted into the slot and fixed to the impeller by friction fit. In the prior art, the magnetic core is generally assembled manually, which is inefficient, has high labor costs, and is prone to errors and omissions. Summary of the Invention

[0039] 2. Set up a counterweight assembly, and the counterweight block abuts against the uppermost end of the magnetic core string in the feed bin. With the cooperation of the counterweight block, the magnetic core string as a whole maintains a downward trend; the counterweight slide bar enables the counterweight block to move downward along a defined path.

[0040] 3. Set a limit assembly and set a groove on the feeding part. One side of the feeding bin will be exposed in the groove.

[0041] 4. Set up a dividing plate driving assembly. The dividing plate sliding base is used to allow the dividing plate to slide on a defined path, and the dividing plate driving member is used to drive the dividing plate to move.

[0042] 5. Set up the assembly head drive assembly so that the assembly head can move in the horizontal and vertical directions. When moving in the horizontal direction, the assembly head can move back and forth above the impeller and above the distribution bin. When moving in the vertical direction, the assembly head can absorb the magnetic core in the distribution bin and insert the magnetic core into the slot of the impeller.

[0043] 6. Set up the turntable assembly and set the positioning parts on the turntable. The positioning parts are used to fix the impeller. Then the impeller is moved under the assembly head through the turntable to facilitate the fixed installation of the impeller and the assembly of the magnetic core by the assembly head.

[0044] 7. Set up the sensing component. The magnetic core position sensor is used to sense whether the assembly head has a magnetic core attached to it. The assembly head is allowed to move down for assembly only when the magnetic core is attached. The hand motion sensor is used to sense whether the worker's hands have left the positioning parts on the turntable. Since the impeller needs to be manually installed on the positioning parts, the subsequent assembly steps can only be carried out after the worker's hands have left the position.

[0045] 8. Set four positioning parts and two groups of assembly components at the same time. Each of the four positioning parts is equipped with an impeller at the same time. The two groups of assembly components assemble the magnetic cores of two adjacent impellers at the same time. Then the turntable rotates 90 degrees. One group of assembly components assembles the remaining magnetic cores of the impeller that is partially assembled with the magnetic core, and the other group of assembly components assembles the magnetic core of the new impeller. The above process is repeated in sequence so that each impeller can complete the assembly of all the magnetic cores.

[0046] 9. There are four feeding bins and distribution bins, which can accommodate two groups of magnetic core strings. There are two magnetic core strings each time. The magnetic poles of the magnetic core strings in the same group are oriented in the same direction, and the magnetic poles of the magnetic core strings in different groups are oriented in opposite directions. At the same time, a magnetic pole identification piece is set on the feeding piece. Before inserting the magnetic core string into the feeding bin, the magnetic pole is first identified on the magnetic pole identification piece to avoid incorrect placement of the magnetic core string.

[0047] 10. Provide a method for using a magnetic core assembly device, based on the above-mentioned magnetic core assembly device, for controlling the magnetic core assembly device to complete the magnetic core assembly operation of the impeller. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] See also Figure 1 , Figure 1 A structural schematic diagram of a magnetic core assembly device provided by the present invention is shown, which is used to assemble a magnetic core 14 into the slot of an impeller 54. Specifically, the magnetic core assembly device includes a machine 70, a turntable assembly 50, a sensor assembly 60 and two groups of assembly components, wherein the first group of assembly components includes a first feeding component 10, a first dividing component 20, a first assembly component 30 and a first assembly head drive component 40, and the second group of assembly components includes a second feeding component 81, a second dividing component 82, a second assembly component 83 and a second assembly head drive component 84. The components used in the two groups of assembly components are completely identical, and only the positions at which they are installed on the machine 70 are different. The following description will take the first group of assembly components as an example.

[0063] In this embodiment, the structures of the magnetic core 14 and the impeller 54 are as follows: Figure 6As shown, the magnetic core 14 is a small cylindrical magnet block, with its two ends forming the two magnetic poles of the magnetic core 14. Multiple magnetic cores 14 can be connected end to end through magnetic attraction to form a magnetic core string. The outer wall of the impeller 54 forms a number of blades, and four slots are evenly arranged along the circumference of the interior. Each slot can be equipped with a magnetic core 14, and one side of the slot is an elastic clamp. The elastic clamp will deform during the insertion of the magnetic core 14 into the slot. At the same time, the elastic clamp will apply force to the magnetic core 14, so that the magnetic core 14 is firmly installed in the slot and will not fall off. In addition, because the impeller 54 is used in the Hall sensor, the magnetic poles of the two magnetic cores 14 in the symmetrical positions of the four slots are the same, while the magnetic poles of the two magnetic cores 14 in adjacent positions are opposite.

[0064] The assembly process for the magnetic cores 14 of this type of impeller 54 requires first assembling two magnetic cores 14 with the same magnetic pole in one assembly group, and then assembling two more magnetic cores 14 with the same magnetic pole in another assembly group. In this embodiment, the magnetic cores 14 with an N-pole at the bottom and an S-pole at the top are assembled in the second assembly group, and then the magnetic cores 14 with an S-pole at the bottom and an N-pole at the top are assembled in the first assembly group.

[0065] The machine table 70 is used to fix the impeller 54 when assembling the magnetic core 14 .

[0066] Specifically, the impeller 54 is secured via the turntable assembly 50. The turntable assembly 50 comprises a turntable 51 and a turntable driver 53. The turntable 53 is equipped with at least one positioning member 52 for securing the impeller. The turntable driver 53 is fixed to the machine platform 70, with its output end fixed to the turntable 51 and driving the turntable 51 to rotate. Furthermore, four positioning members 52 are evenly distributed along the circumference of the turntable 51, each of which simultaneously holds an impeller 54. Two assembly assemblies sequentially assemble the magnetic core 14 of the impellers 54 located on two adjacent positioning members 52.

[0067] like Figure 1 、 Figure 5 and Figure 6 As shown, the turntable 51 is a circular disc structure, which is connected to the turntable drive 53 at the bottom. The turntable drive 53 has an output shaft, and a rotating motor is installed inside. The rotating motor transmits the rotating driving force to the output shaft through a belt drive, so that the output shaft rotates, and the turntable 51 rotates accordingly. And each time the turntable 51 rotates, it rotates 90° counterclockwise, which is exactly the central angle difference between each positioning member 52 and the center of the turntable 51, so that the impeller 54 on the positioning member 52 passes through the second assembly component and the first assembly component in sequence. The four positioning members 52 are arranged according to the following Figure 6The positions shown form the first, second, third and fourth workstations counterclockwise from bottom to top. At the first workstation, the staff manually fixes the impeller 54 on the positioning member 52. At the second workstation, the second group of assembly components assembles the magnetic core 14. At the third workstation, the first group of assembly components assembles the magnetic core 14. At the fourth workstation, the staff manually removes the impeller assembled with the magnetic core 14, and then the positioning member 52 moves back to the first workstation.

[0068] The middle part of the positioning member 52 forms a mounting portion for fixing the impeller 54. The mounting portion is a concave structure with arc-shaped side walls on both sides that match the size of the impeller 54. A positioning column 521 and a positioning block 522 are formed in the middle position. The shapes and sizes of the positioning column 521 and the positioning block 522 match the distance and shape between the two blades on the outside of the impeller 54, so that the impeller 54 can be fixed to the mounting portion on the impeller 52 by plug-in fit. The positioning column 521 and the positioning block 522 have different shapes and can be used as position identification components. When the staff installs the impeller 54, they ensure that a slot on the impeller 54 is located in the position such as Figure 6 The position shown near the positioning post 521 ensures that the impeller 54 is correctly installed.

[0069] Since the first and second assembly groups have the same structure, the first assembly group will be described below as an example. Therefore, the components described below are not prefixed with the first or second prefix, indicating that the second assembly group also includes the following components.

[0070] The first feeding assembly 10 includes a feeding member 11 , a counterweight assembly and a limiting assembly.

[0071] The feeder 11 is fixed to the machine table 70 and is vertically penetrated by at least one feed bin 16 that magnetically holds a plurality of magnetic cores 14 connected at their ends. Four feed bins 16 are provided, two of which are used to accommodate magnetic cores 14 with the same magnetic pole orientation, and the other two are used to accommodate magnetic cores 14 with opposite magnetic pole orientations. A magnetic pole identification member 15 is provided near the inlet of each feed bin 16 on the upper end surface of the feeder 11 to distinguish the magnetic poles of the magnetic cores 14 entering the corresponding feed bin 16.

[0072] The counterweight assembly includes a counterweight block 12 and a counterweight slide 13. The counterweight slide 13 is fixed to the machine platform 70 and is located beside the feeding piece 11 and is arranged vertically. The counterweight block 12 is slidably connected to the counterweight slide 13 and moves in the vertical direction. A counterweight head corresponding to the feeding bin 16 is provided on it. The counterweight head extends into the feeding bin 16 and abuts the end of the magnetic core 14 located at the top.

[0073] The limiting assembly includes a limiting block 18, a limiting driver 19, and a limiting abutment 17. The limiting driver 19 is fixed to the machine platform 70. Its output end is fixed to the limiting block 18 and drives the limiting block 18 to move horizontally. The feeder 11 has a groove 111 at a position corresponding to the limiting block 18, which allows the limiting block 18 to abut against the magnetic core 14 in the feed bin 16. The limiting abutment 17 is fixed to the limiting block 18.

[0074] Specifically, such as Figure 2 and Figure 3 As shown, the feed member 11 is a vertically placed rectangular block, the lower end of which is fixed relative to the machine table 70, and is provided with four feed bins 16. The feed bins 16 vertically penetrate the upper and lower end surfaces of the feed member 11, and form an inlet for the feed bin 16 at the upper end and an outlet for the feed bin 16 at the lower end. The feed bins 16 are open on one side, forming a vertically extending trough structure with two through ends. The bottom of the trough structure is configured in a circular cross-section to adapt to the size of the magnetic core 14. The middle position of the trough to the opening is configured as a channel shape with a uniform width, which is used for the counterweight head to extend into and move along the opening of the feed bin 16. A magnetic pole identification member 15 is provided near the inlet of the feed bin 16. The magnetic pole identification member 15 itself is a magnet, and the magnetic pole at its upper end is fixed. For example, in this embodiment, the first set of assembly components is used to assemble a magnetic core 14 with an S pole at the lower end and an N pole at the upper end. Then the magnetic pole identification member 15 on the feed member 11 can have an N pole at the upper end or an S pole at the upper end. Taking the N pole as an example, when the magnetic core 14 approaches the magnetic pole identification member 15, if they attract each other, the direction of the magnetic core 14 is correct. If they repel each other, the direction of the magnetic core 14 is wrong. When feeding, the magnetic cores 14 are attracted to each other in a head-to-tail state to form a magnetic core string. The magnetic core string can enter the feed bin 16 from the inlet, and because the feed bin 16 has a cylindrical cavity whose size matches the size of the magnetic core 14, when the magnetic core string is located in the feed bin 16, it will remain connected to each other and remain in a string in the vertical direction. A groove portion 111 is provided near the bottom end of the feeding piece 11. The groove portion 111 is recessed downward relative to the side wall of the feeding piece 11 and is recessed all the way to the position of the cylindrical cavity of the feeding bin 16, so that the magnetic core 14 in the feeding bin 16 is completely exposed at the position of the groove portion 11, so that the limit block 18 can abut against the magnetic core 14 at this position, limiting the magnetic core 14 from continuing to move downward.

[0075] The counterweight slide 13 is located on one side of the feeding member 11. It is a vertically arranged rod with both ends directly fixed to the feeding member 11. A through hole is formed on one side of the counterweight block 12, and the counterweight slide 13 passes through the through hole, so that the counterweight block 12 can move up and down along the counterweight slide 13. At the same time, a sliding end is provided at the other end of the counterweight block 12. The feeding member 11 is provided with a vertically extending sliding groove on the side wall corresponding to the sliding end. The sliding end of the counterweight block 12 extends into the sliding groove, thereby cooperating with the counterweight slide 13 to allow the counterweight block 12 to move up and down in a stable posture. Four counterweight heads are arranged on the side wall of the counterweight block 12 facing the feed bin 16. The counterweight heads are columnar structures, and their positions correspond to the side openings of the feed bin 16. Their ends extend into the feed bin 16. When a magnetic core string is contained in the feed bin 16, the end of the counterweight head just abuts against the top end of the magnetic core string, and under the action of the counterweight block 12, the magnetic core string is pressed downward, causing the magnetic core string to move downward.

[0076] The limit drive member 19 is fixed relative to the machine 70. It is a cylinder drive device, and its output shaft is fixed to the limit block 18, which is used to drive the limit block 18 to move forward and backward. A limit abutment member 17 is also fixed to the limit block 18. The limit abutment member 17 is used to abut the side wall of the feed member 11 when the limit block 18 moves forward, thereby preventing the cylinder from driving the limit block 18 to move too far. The position of the limit block 18 corresponds to the groove portion 111 on the feed member 11. When the limit block 18 moves forward to the position abutting the feed member 11 under the drive of the cylinder, it will abut the magnetic core 14 exposed on the groove portion 111, thereby limiting the magnetic core 14 from continuing to move downward. After the limit block 18 leaves the abutment position, the magnetic core 14 will move downward again under the action of the counterweight 12.

[0077] The first dividing assembly 20 includes a dividing plate 21 and a dividing plate driving assembly.

[0078] The dividing plate 21 is installed on the machine and moves relative to the feeding piece 11, and its upper surface is in contact with the lower end surface of the feeding piece 11. It is provided with a dividing bin 211 corresponding to the feeding bin 16 for accommodating a single magnetic core 14. There are four dividing bins 211, which correspond to the four feeding bins 16 of the feeding piece 11 respectively.

[0079] The dividing plate driving assembly includes a dividing plate driving member 22 and a dividing plate sliding base 23 both of which are fixed to the machine. The output end of the dividing plate driving member 22 is fixed to the dividing plate 21 and drives the dividing plate 21 to move in the horizontal direction. The dividing plate sliding base 23 is provided with a dividing plate slide rail 231 extending in the horizontal direction, and the dividing plate 21 is provided with a dividing plate slide groove adapted to the dividing plate slide rail 231.

[0080] Specifically, such as Figure 2 and Figure 3As shown, the dividing plate 21 is a plate-shaped component with a smooth surface, and its front end position ( Figure 3 The separator 21 is provided with four distribution bins 211 (at the far end). The size of the distribution bins 211 matches the size of the magnetic cores 14, and the depth thereof can only accommodate a single magnetic core 14. The upper surface of the distribution plate 21 is in contact with the lower end surface of the feeding member 11. When the distribution bin 211 of the distribution plate 21 moves to the bottom of the feeding member 11 and corresponds to the discharge port of the feeding bin 16, a magnetic core 14 in the feeding bin 16 will fall into the distribution bin 211. Then the distribution plate 21 moves forward to separate the magnetic core 14 that falls into the distribution bin 211 from the other magnetic cores 14 in the feeding bin 16. The magnetic cores 14 in the feeding bin 16 are blocked by the upper surface of the distribution plate 21 so that the magnetic cores 14 inside will not continue to fall. A distribution plate chute is provided on the lower surface of the distribution plate 21. The extension direction of the distribution plate chute is consistent with the moving direction of the distribution plate 21.

[0081] The divider plate driver 22 is a pneumatic cylinder device with an output end directly connected to the divider plate 21 for driving the divider plate 21 to move forward and backward. The divider plate sliding base 23 is directly fixed to the machine table 70 and is provided with a divider plate slide rail. The extension direction of the divider plate slide rail is consistent with the movement direction of the divider plate 21. At the same time, its size is adapted to the divider plate chute. The divider plate chute can be plugged into the divider plate slide rail from the side, thereby limiting the movement path of the divider plate 21.

[0082] The first assembly component 30 includes an assembly head driver 31, an assembly head 32, an assembly head abutment 33, and an impeller abutment 34. The assembly head 32 is mounted on the machine platform and moves horizontally and vertically. It is used to move above the material distribution bin 211 and then move downward to magnetically attract the magnetic core 14 in the material distribution bin 211. It also moves above the impeller 54 and then moves downward to insert the magnetic core 14 into the slot.

[0083] Specifically, such as Figure 4As shown, the assembly head 32 is composed of two slender cylindrical components made of iron. The assembly head driver 31 is fixed to the first assembly head drive assembly 40. It is a cylinder drive device with its output end fixed to the assembly head 32 and used to drive the assembly head 32 to move up and down. The assembly head abutment member 33 is also fixed to the output shaft of the assembly head driver 31. Below the assembly head abutment member 33 is an impeller abutment member 34 fixed to the first assembly head drive assembly 40. The assembly head abutment member 33 is used to abut the upper surface of the impeller abutment member 34 when the assembly head 32 moves downward, preventing the assembly head 32 from moving too far downward. The impeller abutment member 34 is used to abut the impeller 54 when the assembly head 32 moves downward, preventing the vertical moving member of the first assembly head drive assembly 40 from moving too far downward. The assembly head 32 extends into the impeller abutment member 34, and at the position corresponding to the assembly head 32, the impeller abutment member 34 is provided with a through hole at the position corresponding to the assembly head 32, through which the end of the assembly head 32 can be seen from the side wall.

[0084] The first assembly head drive assembly 40 includes a first assembly drive member 42, a first assembly sliding base 41, a first assembly slide 43, a second assembly drive member 44, and a second assembly slide 45. The first assembly slide base 41 is fixed to the machine platform 70 and is provided with a first assembly slide rail 411 extending horizontally. The first assembly slide 43 is provided with a first assembly slot adapted to the first assembly slide rail 411. The output end of the first assembly drive member 42 is fixed to the first assembly slide 43 and drives the first assembly slide 43 to move horizontally. The first assembly slide 43 is provided with a second assembly slide rail 431 extending vertically. The second assembly slide 45 is provided with a second assembly slot adapted to the second assembly slide rail 431. The output end of the second assembly drive member 44 is fixed to the second assembly slide 45 and drives the second assembly slide 45 to move vertically. The assembly head 32 is mounted on the second assembly slide 45.

[0085] Specifically, such as Figure 4As shown, the first assembly sliding base 41 is fixedly connected to the machine table 70 through a vertically arranged support plate. The first assembly sliding base 41 is a plate-like component arranged horizontally, and the above-mentioned first assembly slide rail 411 is convexly provided on one side surface thereof. The extension direction of the first assembly slide rail 411 is the same as the extension direction of the first assembly sliding base 41, and is the same as the movement trajectory of the assembly head 32 in the horizontal direction. The first assembly driving member 42 is fixed on the first assembly sliding base 41, and its output end is fixedly connected to the first assembly sliding member 43, which is a cylinder driving device for driving the first assembly sliding member 43 to slide along the first assembly slide rail 411. A first assembly slide groove is provided on the side of the first assembly sliding member 43 facing the first assembly sliding base 41. The cross-section of the first assembly slide groove is T-shaped, and the cross-section of the first assembly slide rail 411 is also T-shaped to match it. After the two are matched, it can be ensured that the first assembly slide 43 will not fall off the first assembly slide rail 411.

[0086] A second assembly driver 44 is fixedly connected to the first assembly slide 43. A second assembly rail 431 is also provided on the side of the first assembly slide 43 facing away from the first assembly rail 411. The output end of the second assembly driver 44 is fixedly connected to the second assembly slide 45. This cylinder drive device is used to drive the second assembly slide 45 to move vertically along the second assembly rail 431 through a second assembly chute provided on the back. The first assembly component 30 is mounted on the second assembly slide 43. The assembly head driver 31 is fixedly connected to the second assembly slide 43. The impeller abutment 34 is also fixedly connected to the lower end of the second assembly slide 43.

[0087] In addition, a shift drive member 46 and a shift drive push rod 461 are provided. The shift drive member 46 is fixed to the first assembly sliding base 41. It is a cylinder drive device, and its output end is fixed to the shift drive push rod 461, which is used to drive the shift drive push rod 461 to move forward and backward. When the shift drive push rod 461 moves forward, it abuts against the first assembly sliding member 43. When the assembly head 32 needs to move above the two more distant sub-bins 211, the shift drive push rod 461 pushes the first assembly sliding member 43 toward the more distant sub-bins 211, so that the assembly head 32 is above these two more distant sub-bins 211.

[0088] In addition, it also includes a sensor component 60, which includes a magnetic core position sensor and a hand motion sensor. The magnetic core position sensor is used to detect whether the secondary magnetic core 14 is adsorbed on the assembly head 32 located above the impeller 54, and the hand motion sensor is used to detect whether the hand of the staff who fixes the impeller 54 has left.

[0089] Specifically, the magnetic core position sensor and the hand motion sensor are both photoelectric sensors. The position of the magnetic core position sensor corresponds to the through hole of the assembly head 32 on the impeller abutment 34. When the magnetic core 14 is adsorbed on the assembly head 32, the sensing light of the magnetic core position sensor will be blocked, thereby generating a detection signal; the hand motion sensor will also generate a detection signal when it senses that there is a staff member's hand blocking the turntable 51.

[0090] In addition, the present invention also provides a method for using a magnetic core assembly device, which is based on the magnetic core assembly device provided in the above embodiment and specifically includes the following steps:

[0091] Step 1: insert a plurality of magnetic cores 14 connected at their ends by magnetic attraction into the feeding bin 16 of the feeding member 11;

[0092] Step 2: Fix the impeller 54 on the machine platform 70;

[0093] Step 3: Drive the dividing plate 21 to move, so that a magnetic core 14 in the feeding bin 16 falls into the dividing bin 211;

[0094] Step 4: Drive the separating plate 21 to move and separate the magnetic core 14 that falls into the separating bin 211 from the other magnetic cores 14;

[0095] Step 5: Drive the assembly head 32 to move above the material bin 211, move down and absorb the magnetic core 14 in the material bin 211;

[0096] Step 6: Drive the assembly head 32 upward to move above the slot of the impeller 54, then move downward and insert the magnetic core 14 into the slot of the impeller 54;

[0097] Step 7: Drive the assembly head 32 upward to complete the assembly of the magnetic core 14 .

[0098] Specifically, first of all, loading is required, and the magnetic core string is inserted into the feeding bin 16 from the feeding port of the feeding bin 16 above the feeding piece 11, and the counterweight head of the counterweight block 12 is abutted against the upper end face of the uppermost magnetic core 14, and then the impeller 54 is installed on the four positioning parts 52 on the turntable 51, and then the limit block 18 is controlled to leave the feeding piece 11, and then the distribution bin 211 of the distribution plate 21 is controlled to move to the bottom of the discharge port of the feeding bin 16, so that the magnetic core 14 falls into the distribution bin 211, and then the limit block 18 is controlled to abut the magnetic core 14 in the feeding bin 16, and then the distribution plate 21 is controlled to move forward to the predetermined position Then, control the first assembly slide 43 to move above the dividing plate 21, and make the assembly head 32 be located above the two dividing bins 211 that are closer to each other, control the second assembly slide 45 to move downward, and then control the assembly head 32 to move downward to adsorb the magnetic cores 14 in the two dividing bins 211, and then control the assembly head 32 to move upward, control the second assembly slide 45 to move upward, and then control the first assembly slide 43 to return to the top of the impeller 54, and then control the second assembly slide 45 to move downward, and then control the assembly head 32 to move downward again to insert the magnetic core 14 into the slot of the impeller 54 to complete the assembly of the magnetic core 14.

[0099] When assembling the next impeller 54 , the first assembly sliding member 43 is moved to above two relatively distant sub-bins 211 by the shift driving member 46 , and then the subsequent steps are repeated.

[0100] The present invention provides a magnetic core assembly device and a corresponding method of use. By providing a feeding member 11, a dividing plate 21 and an assembly head 32, the magnetic core 14 can be automatically assembled onto the impeller 54, which can effectively improve assembly efficiency and reduce labor costs.
