Description

Technical Field

[0001] The present invention relates to the technical field of electric planer assembly, and in particular to an automatic assembly device and assembly process for an electric planer. Background Art

[0002] An electric planer is a power tool used for processing wooden boards. The surface of the wooden board is made flat and smooth by the planer blade of the electric planer.

[0003] An electric planer is composed of a motor, a cutter chamber structure, a cutting depth adjustment mechanism, a handle, a switch, a non-reconnectable plug, etc. When producing an electric planer, these components need to be assembled in a housing. The traditional assembly of an electric planer is carried out manually on a table. In this way, the work efficiency is low and the assembly quality is controlled by the proficiency of the workers.

[0004] Especially when assembling the cutting depth adjustment plate, a spring needs to be pre-placed in the hole of the depth adjustment plate, and then the depth adjustment plate together with the spring is inserted upside down into the installation position of the electric planer housing. During the inversion process, the spring will fall downward. Therefore, during the process of the depth adjustment plate approaching the installation position of the electric planer housing, it is necessary to manually hold against the spring to prevent the spring from falling. Only after the spring is partially inserted into the housing installation position can the holding be released. Such an operation is to make the spring sleeved on the depth adjustment shaft and located in the hole of the depth adjustment plate after installation. Therefore, this step in the assembly takes a long time, and at the same time, a simple automatic device cannot be used to complete this operation, which is a technical difficulty in the overall assembly automation transformation.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1

[0032] See Figures 1-7 , an automatic assembly device for an electric planer. The electric planer 5 includes a housing 51, a depth adjustment shaft 52 and a depth adjustment plate 53. The automatic assembly device includes a device frame 1, a screwing device 2 and a flipping and pressing device 3. A workbench and a central control unit are configured on the device frame 1. The central control unit is used to control the operation of electrical components in the device. The screwing device 2 includes a servo motor. The servo motor is fixedly configured on the workbench, and a bushing adapted to the depth adjustment shaft is configured at the shaft end of the servo motor. The servo motor is controlled by the central control unit.

[0033] A cavity adapted to the housing 51 of the electric planer is provided on the workbench. After the housing 51 of the electric planer is positioned and placed in the cavity, the rear end plate 54 on the bottom surface of the electric planer is in a horizontal state. When installing the depth adjustment plate 53, the blade shaft 55, the rear end plate 54 on the bottom surface and the depth adjustment shaft 52 on the electric planer have all been installed. After the electric planer is positioned and placed on the cavity, the rear end plate on the electric planer is in a horizontal state. A pressing cylinder assembly 11 for pressing the electric planer is configured on the workbench. After the electric planer is installed, the central control unit controls the pressing cylinder assembly 11 to press the electric planer.

[0034] The pressing cylinder is a 90-degree rotating pressing cylinder. When it is opened, the pressing block on the cylinder leaves the position above the electric planer, so that the electric planer can be quickly positioned and installed in the cavity. When pressing, the pressing cylinder rotates 90 degrees first during the downward movement, and then vertically presses to press the electric planer in the cavity, so that the rear end face 54 on the electric planer is in a horizontal state.

[0035] The flipping and pressing device 3 includes a positioning component 31, a flipping member 32, a pressing member 33 and an elastic transition member 34. The pressing member 33 is configured on the workbench and is composed of a cylinder or a hydraulic cylinder. The flipping member 32 is configured at the upper end of the telescopic rod of the pressing member 33. The telescopic rod of the pressing member 33 moves up and down to drive the flipping member 32 to move up and down. The flipping member 32 is configured with a first limiting member 321, a second limiting member 322 and a locking tongue member 323. The first limiting member 321 and the second limiting member 322 are respectively located on the left and right sides of the flipping member 32. The locking tongue member 323 is located above the second limiting member 322, and a rotating motor for driving the positioning component 31 to rotate is configured at the middle position between the first limiting member 321 and the second limiting member 322.

[0036] The positioning component 31 includes a base member 311 and a positioning member 312. One side of the base member 311 is arranged on the rotating shaft of the rotating motor, and the rotating motor can drive the base member 311 to flip 180 degrees. In the initial state, the base member 311 faces upward, and the lower end surface of the base member 311 presses against the first limiting member 321, so that the base member 311 is in a horizontal state. At this time, the depth adjustment plate 53 is used for placement and the spring is placed into the hole of the depth adjustment plate 53.

[0037] An elastic transition member 34 is arranged on the bottom surface of the base member 311, and a suction cup for vacuum adsorbing the depth adjustment plate 53 is arranged on the elastic transition member 34. A plurality of the suction cups are evenly distributed. At the same time, a first magnetic attraction member is also arranged on the elastic transition member 34, and an electric telescopic member 313 is also arranged on the base member 311. The positioning member 312 is arranged at the front end of the telescopic rod of the electric telescopic member 313. The electric telescopic member 313 controls the forward and backward telescoping of the positioning member 312. A pipe sleeve 531 is arranged on the depth adjustment plate 53, and an internally threaded pipe fitting 532 is also arranged in the pipe sleeve 531. The internally threaded pipe fitting 532 is used for threaded cooperation with the depth adjustment shaft 52. The spring is placed in the pipe sleeve 531 and sleeved on the internally threaded pipe fitting 532. A groove adapted to the pipe fitting 531 is opened at the front end of the positioning member 312.

[0038] In the initial state, the depth adjustment plate 53 is positioned and placed on the base member 311 by a manipulator. At this time, the electric telescopic member 313 contracts, and then drives the positioning member 312 to extend and abut against the pipe fitting 531, further guiding and positioning the depth adjustment plate 53. The first magnetic attraction member on the base member 311 is located below the pipe sleeve 531. After the manipulator places the spring into the pipe sleeve 531, the first magnetic attraction member adsorbs the bottom of the spring at an interval equal to the plate thickness of the depth adjustment plate 53. Second magnetic attraction members are arranged on both sides of the front-end groove of the positioning member 312. After the positioning member 312 moves in place, the second magnetic attraction members magnetically attract the side wall of the spring at an interval equal to the wall thickness of the pipe sleeve 531. At the same time, the suction cup on the base member 311 starts to work, adsorbing the depth adjustment plate 53 on the base member 311.

[0039] The rotating motor starts to rotate, driving the base member 311 to flip 180 degrees, so that the upper end surface of the base member 311 presses against the second limiting member 322. During the rotation process, under the action of double magnetic attraction, the spring will not be thrown outwards. After flipping 180 degrees, the positioning member 312 starts to retract and leaves below the depth adjustment plate 53. The magnetic attraction force of the first magnetic attraction member on the spring is greater than the gravity of the spring itself. Therefore, when the positioning member 312 leaves below the depth adjustment plate 53, the spring will not fall down under the action of the first magnetic attraction member.

[0040] The latch member 323 is an elastic telescopic member, and the upper end surface of the latch member 323 is an arc surface, and the lower end surface is a flat surface. When the arc surface is pressed, the latch member 323 retracts backward into the flipping member 32. Among them, during the process that the base plate 311 flips and presses on the second limiting member 322 from the first limiting member 321, it presses on the arc surface of the latch member 323. When the base plate 311 presses on the second limiting member 322, the latch member 323 just pops outwards, and its lower end surface contacts the upper end surface of the base plate 311 at this time. Then, through the limiting of the latch member 323 and the second limiting member 322, the base plate 311 is locked at the 180-degree position. And a retracting member is arranged at the rear end of the latch member 323. The retracting member can be an electromagnet. After the assembly is completed, when the base plate 311 needs to be reset, the electromagnet is energized, and then the latch member 323 is adsorbed into the flipping member 32, eliminating the limit on the base plate 311, so that the base plate 311 can be reset.

[0041] At the same time, the retracting member can also be an electric telescopic rod. The latch member 323 is elastically and slidably arranged in the latch housing. The latch housing is slidably arranged on the flipping member 32. An electric telescopic member is connected to the rear end of the latch housing. When reset is required, the electric telescopic rod retracts, and then drives the latch housing to move backward, so that the latch member 323 retracts into the flipping member 32, thereby realizing the function of releasing the limit.

[0042] At this time, the sleeve 531 on the depth adjustment plate 53 is aligned with the installation position on the housing 51. The pressing member 33 starts to contract, and then the flipping member 32 moves downward. And at this time, the bottom surface of the depth adjustment plate 53 faces downward. During the downward movement, the sleeve 531 is inserted into the installation position on the housing 51.

[0043] The elastic transition member 34 includes a guiding sleeve 341, a limiting guiding rod 342 and a first elastic member 343. The guiding sleeve 341 is arranged on the base member 311. One end of the limiting guiding rod 342 is arranged in the guiding sleeve 341 in a limiting guiding and sliding manner, and the other end is provided with a suction cup plate 344. The suction cups for adsorbing the depth adjustment plate 53 are evenly distributed on the suction cup plate 344. The first elastic member 343 is sleeved on the guiding sleeve 341 and the limiting guiding rod 342, and the two ends respectively abut against the base member 311 and the suction cup plate 344. A pressure sensor is arranged at the position on the base member 311 where the first elastic member 343 abuts, for monitoring the pressure value fed back by the suction cup plate 344.

[0044] A concave hole is formed on the bottom surface of the suction cup plate 344. The suction cups are arranged in the concave hole. And when the suction cups adsorb the base member 311, the base member 311 abuts against the bottom surface of the suction cup plate 344.

[0045] During the process of inserting the sleeve 531 into the housing 51, the suction cups on the suction cup plate 344 stop adsorbing the depth adjustment plate 53. The upward reaction force received by the suction cup plate 344 is only the frictional force between the outer wall of the sleeve 531 and the wall of the mounting hole of the housing 51. The magnitude of the frictional force is within a set range of N1 - N2. During the downward movement of the pressing member 33, the servo motor of the screwing device 2 starts to rotate. When the internal threaded sleeve of the depth adjustment plate 53 touches the depth adjustment shaft 52, there will be a phenomenon that the threads do not match when they first come into contact. Therefore, the depth adjustment plate 53 cannot move downward at this time. As a result, the pressure detected by the pressure sensor gradually increases. When N3 detected by the pressure sensor > N2, the central control unit controls the servo motor to increase the rotation speed to accelerate the thread matching. At the same time, the limit guiding rod 342 relatively extends into the guiding sleeve 341 to provide a buffer space for the thread matching. When the threads match, the value of N3 drops rapidly. When N3 is between N1 and N2, the rotation speed is slowly reduced to make N3 stable between N1 and N2.

[0046] When N3 > N2, that is, the downward movement speed of the pressing member 33 is greater than the downward movement speed of the thread screwing, the central control unit controls the servo motor to increase the rotation speed. When N3 < N1, that is, the downward movement speed of the pressing member 33 is less than the downward movement speed of the thread screwing, the central control unit controls the servo motor to reduce the rotation speed.

[0047] When the pressing member 33 moves downward to the lowest point and the pressure value detected by the pressure sensor coincides with the initial N0, at this time, the bottom surface of the suction cup plate 344 and the bottom surface of the rear end plate 54 of the electric planer 5 are on the same horizontal plane. That is, during the downward pressing and screwing process, when the pressure value detected by the pressure sensor is N0, the screwing device 2 stops working. At this time, the bottom surface of the depth adjustment plate 53 and the bottom surface of the rear end plate 54 are on the same horizontal plane, and at this time, the installation of the depth adjustment plate 53 is completed.

[0048] Its working principle or usage method is as follows: In the initial state, the electric planer with the depth adjustment plate 53 to be installed is positioned and placed in the positioning concave cavity of the workbench by the manipulator, and the pressing cylinder assembly 11 is used to press the electric planer. At this time, the base member 311 presses against the first limiting member 321. The depth adjustment plate 53 is positioned and placed on the base member 311 by the manipulator, and the spring is positioned and placed into the sleeve 531. At this time, the positioning member 312 extends and abuts against the pipe fitting 531 to further guide and position the depth adjustment plate 53. The second magnetic attracting member on the positioning member 312 magnetically attracts the side wall of the spring at an interval of the wall thickness of the sleeve 531. At the same time, the one on the suction cup plate 344 starts to work, adsorbing the depth adjustment plate 53 on the base member 311. The first magnetic attracting member is also arranged on the suction cup plate 344, and the first magnetic attracting member magnetically attracts the bottom of the spring at an interval of the plate thickness of the depth adjustment plate 53.

[0049] After the suction cup is activated, the rotating motor starts to rotate, driving the base member 311 to flip 180 degrees. During the flipping process, the base member 311 presses against the arc surface of the locking tongue member 323, causing the locking tongue member 323 to elastically retract into the flipping member 32. When the base plate 311 presses against the second limiting member 322, the locking tongue member 323 just pops outwards, and its lower end surface contacts the upper end surface of the base plate 311 at this time. Then, through the limitation of the locking tongue member 323 and the second limiting member 322, the base plate 311 is locked in the 180-degree position.

[0050] Meanwhile, during the rotation process, under the action of double magnetic attraction, the spring will not be thrown outwards. After flipping 180 degrees, the positioning member 312 starts to retract and leaves below the depth adjustment plate 53. And the magnetic attraction force of the first magnetic attracting member on the spring is greater than the gravity of the spring itself. Therefore, when the positioning member 312 leaves below the depth adjustment plate 53, the spring will not fall down under the action of the first magnetic attracting member.

[0051] At this time, the pressing member 33 starts to work, driving the depth adjustment plate 53 and the spring to move downwards together, inserting the sleeve 531 into the housing 51. When the value detected by the pressure sensor starts to be greater than N1, the suction cup on the suction cup plate 344 stops adsorbing. At the same time, the servo motor of the screwing device 2 starts to rotate, driving the depth adjustment shaft 52 to rotate, and screwing the thread on the depth adjustment shaft 52 into the internal threaded sleeve of the depth adjustment plate 53, thus completing the installation work.

[0052] Based on the pressure value detected by the pressure sensor, the central control unit controls the rotation speed of the servo motor to stably install the depth adjustment plate 53 on the electric planer. Embodiment 2

[0053] See Figures 1-7 In this embodiment, the following further improvements are made on the basis of Embodiment 1: The flipping and pressing device 3 is further configured with a detection device. The detection device includes a detection substrate. The detection substrate 351 is fixedly configured on the base member 311, and the rear end area of the detection substrate 351 extends above the installation position of the rear end plate 54. A plurality of laser distance sensors are configured on the detection substrate 351, at least 3 are configured above the depth adjustment plate 53, and at least 1 is configured above the rear end plate 54. The plurality of laser distance sensors above the depth adjustment plate 53 are used to monitor the height difference of multiple position points on the depth adjustment plate 53, so as to identify whether the depth adjustment plate 53 is in a horizontal state, and the laser distance sensor located above the rear end plate 53 is used to monitor the height of the rear end plate 53 as a reference value.

[0054] Among them, when the pressure value detected by the pressure sensor is N0, the detection device 35 is activated, and the laser distance sensor is used to monitor whether the height of the rear end plate 53 is consistent with the height of the depth adjustment plate 53.

[0055] If there is a height difference, first control the forward or reverse rotation of the servo motor to adjust the relative height between the depth adjustment plate 53 and the rear end plate 53 so that the two are at the same horizontal height.

[0056] After the height is adjusted to the same level, the detection work begins. That is, the pressing member 33 rises to a set height, and the servo motor is started to rotate again, so that the depth adjustment plate 53 descends. During the descent, it is detected whether the reading difference of the three laser distance sensors located above the depth adjustment plate 53 is within the set allowable tolerance, and the height distance of the three points is used to determine whether the depth adjustment plate 53 always remains horizontal with the rear end plate 53 during the up and down movement.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
