DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0030] See Figure 1 A household induction cooker circuit board production and detection tooling includes a tooling frame 1, a detection mechanism 2 for detecting the position of electronic components on the circuit board is provided on the upper part of the tooling frame 1, and a pushing mechanism 3 for positioning and moving the circuit board is provided on the tooling frame 1.

[0031] When it is necessary to inspect the circuit board of the induction cooker, first adjust the pushing mechanism 3 according to the shape of the circuit board, and then adjust the detection mechanism 2 according to the position and number of electronic components on the circuit board. After that, the circuit board is moved and placed inside the tooling rack 1. The pushing mechanism 3 adaptively positions the circuit board and pushes it onto the detection mechanism 2, so that the detection mechanism 2 can perform intuitive and quick inspections on whether the electronic components on the circuit board are missing and the verticality of the installation.

[0032] See Figure 1 and Figure 2 The pushing mechanism 3 includes a rectangular plate 31 that slides up and down inside the tooling frame 1. A No. 1 adjustment plate 32 is provided on the upper part of the rectangular plate 31 for sliding left and right. A No. 2 adjustment plate 33 is provided on the upper part of the No. 1 adjustment plate 32 for sliding back and forth. A plurality of electric suction cups 34 arranged in a matrix are fixedly installed on the upper part of the No. 2 adjustment plate 33. The lower part of the rectangular plate 31 is connected to a lifting plate 35 that slides up and down through a guide column.

[0033] It should be noted that push springs are provided between the left and right sides of the No. 1 adjustment plate 32 and the rectangular plate 31, and between the front and rear sides of the No. 2 adjustment plate 33 and the No. 1 adjustment plate 32. The push springs on the left and right sides of the No. 1 adjustment plate 32 can push the No. 1 adjustment plate 32 to the middle position of the rectangular plate 31 through their own elastic force in the absence of external force, and the No. 1 adjustment plate 32 drives the No. 2 adjustment plate 33 to move synchronously. Similarly, the push springs in the corresponding position push the No. 2 adjustment plate 33 to the middle position of the No. 1 adjustment plate 32, so that the No. 1 adjustment plate 32 is located at the center position of the rectangular plate 31 in the absence of external force.

[0034] Continue reading Figure 1 and Figure 2 A pushing member 37 for pushing the circuit board is connected to the lifting plate 35 through an adjusting component 36. The pushing member 37 has a U-shaped structure. The upper part of the two vertical sections of the pushing member 37 is chamfered on one side close to the center of the lifting plate 35. The vertical sections of the front and rear pushing members 37 are respectively located on the left and right sides of the No. 1 adjustment plate 32, and the vertical sections of the front and rear pushing members 37 are respectively attached to the left and right sides of the No. 1 adjustment plate 32.

[0035] Since the vertical sections of the front and rear pushers 37 are attached to the left and right sides of the No. 1 adjustment plate 32, when the No. 1 adjustment plate 32 slides left and right, the No. 1 adjustment plate 32 can drive the front and rear pushers 37 to move synchronously, thereby preventing the front and rear pushers 37 from hindering the sliding of the No. 1 adjustment plate 32, and enabling the front and rear pushers 37 to be accurately aligned with the position of the circuit board, so that the front and rear pushers 37 can push and limit the position of the circuit board.

[0036] Continue reading Figure 1 and Figure 2The adjustment component 36 includes four track plates 361 arranged on the upper part of the lifting plate 35. The track plates 361 are arranged parallel to the edges of the corresponding positions of the lifting plate 35, and the track plates 361 are slidingly connected to the edges of the corresponding positions of the lifting plate 35 in a direction perpendicular to the edges of the lifting plate 35. The side of the track plate 361 close to the center of the lifting plate 35 is slidingly connected to the push member 37 along the length direction of the track plate 361.

[0037] See Figure 2 The adjustment component 36 also includes a No. 1 screw 362 that is rotatably arranged on the lifting plate 35 and corresponds one-to-one to the track plate 361. The No. 1 screw 362 is arranged along the length direction perpendicular to the track plate 361 at the corresponding position, and the No. 1 screw 362 is threadedly connected to the track plate 361 at the corresponding position.

[0038] Before inspecting the circuit board, the operator manually rotates the four No. 1 screws 362 separately in advance, so that the No. 1 screws 362 drive the pushers 37 at the corresponding positions to adjust their positions through the track plate 361, so that the pushers 37 can push the circuit board to the specified position, and by adjusting the positions of the four pushers 37 separately, circuit boards of different shapes can be pushed.

[0039] See Figure 1 、 Figure 3 and Figure 4 The detection mechanism 2 includes a placement plate 21 fixedly mounted on the upper part of the tooling frame 1, and the lower part of the placement plate 21 is detachably connected to the mounting plate 23 through a connecting component 22. The connecting component 22 includes upper and lower clearance holes 221 that are arranged in a matrix on the placement plate 21. The lower side of the placement plate 21 is provided with several groups of clips 222 that correspond one-to-one to the clearance holes 221. Each group is composed of four clips 222 that are arranged at equal intervals along the circumference of the clearance hole 221 on the lower side of the placement plate 21. The clips 222 are slidably connected to the placement plate 21 along the radial direction of the corresponding clearance hole 221, and a return spring is provided between the placement plate 21 and the clips 222.

[0040] See Figure 3 、 Figure 4 and Figure 5 The connecting assembly 22 also includes positioning posts 223 fixedly mounted on the upper side of the mounting plate 23 at equal intervals along the circumference of the insertion tube 24, and positioning holes 224 for inserting the positioning posts 223 are provided around each of the clearance holes 221 on the placement plate 21.

[0041] After the position of the pushing member 37 is adjusted, the pushing member 37 can push the electric plate to the specified position, so that the electronic components on the circuit board can be moved to directly below the clearance hole 221. Then the operator moves the mounting plate 23 from bottom to top until it is in contact with the lower side of the placement plate 21, so that the mounting plate 23 can be located directly above the electronic components on the circuit board.

[0042] The mounting plate 23 drives the positioning post 223 thereon to move synchronously, so that the positioning post 223 is inserted into the positioning hole 224 at the corresponding position on the placement plate 21, so that the mounting plate 23 and the placement plate 21 are slidably connected up and down, and then the mounting plate 23 continues to move upward. The four edges of the mounting plate 23 push the corresponding position buckles 222 away from the mounting plate 23. When the upper side surface of the mounting plate 23 is attached to the lower side surface of the placement plate 21, the return spring pushes the buckle 222 to return to its original position through its own elastic force, so that the buckle 222 blocks and limits the mounting plate 23, thereby locking the mounting plate 23 and the placement plate 21 into a whole.

[0043] The operator then repeats the step of connecting the mounting plate 23 to the placement plate 21 so that the mounting plate 23 can correspond to being directly above each electronic component that needs to be inspected.

[0044] See Figure 1 and Figure 2 The pushing mechanism 3 also includes a driving assembly 38 for driving the circuit board to move upward. The driving assembly 38 includes an electric push rod 381 fixedly mounted on the inner bottom wall of the tooling frame 1. The telescopic section of the electric push rod 381 is fixedly connected to the lifting plate 35. A tension spring No. 1 is provided between the lifting plate 35 and the rectangular plate 31. A limit frame 382 for blocking the rectangular plate 31 is fixedly installed in the middle of the tooling frame 1.

[0045] In the initial state, the lower side surface of the rectangular plate 31 rests on the limit frame 382, ​​and the telescopic section of the electric push rod 381 drives the lifting plate 35 to lengthen the No. 1 tension spring. At the same time, the lifting plate 35 drives the pushing member 37 to be completely located at the bottom of the electric suction cup 34 through the track plate 361.

[0046] When inspecting the circuit board, the operator places the circuit board on the upper side of the electric suction cup 34, and uses the electric suction cup 34 to adsorb the circuit board so that the circuit board is locked into a whole with the No. 2 adjustment plate 33 through the electric suction cup 34. Then, the telescopic section of the electric push rod 381 is extended, so that the electric push rod 381 drives the pushing member 37 to move upward. Due to the pulling force of the No. 1 tension spring on the rectangular plate 31, the height of the rectangular plate 31 remains unchanged, thereby making the height of the circuit board of the rectangular plate 31 remain unchanged, and then the pushing member 37 moves upward relative to the circuit board.

[0047] The pushing member 37 contacts the edge of the circuit board through the chamfer provided on it, and then the pushing member 37 pushes the circuit board to move. When the chamfers of the four pushing members 37 all contact the edge of the circuit board, the pushing member 37 pushes the circuit board to the specified position, and at the same time makes the position of each electronic component to be detected on the circuit board directly below the mounting plate 23 at the corresponding position. At this time, because the tension spring drives the pushing member 37 to press against the circuit board through its own tension, the lifting plate 35 begins to drive the circuit board to move upward synchronously.

[0048] See Figure 1 、 Figure 3 and Figure 4 The detection mechanism 2 also includes an insertion tube 24 that slides up and down inside the mounting plate 23. A square plate 25 is fixedly installed at the lower part of the insertion tube 24. Four triangular plates 26 corresponding to the rectangular sides of the square plate 25 are slidingly arranged at the lower part of the square plate 25. The detection mechanism 2 also includes a leak detection component 28 arranged on the mounting plate 23.

[0049] See Figure 3 and Figure 4 The leak detection assembly 28 includes a No. 2 screw 281 threadedly connected to the mounting plate 23. The No. 2 screw 281 is located at a coaxial position inside the insertion tube 24. The upper end of the No. 2 screw 281 is fixedly mounted with a No. 2 lamp 282, and the lower end of the No. 2 screw 281 is fixedly mounted with a No. 2 micro switch 283 for controlling the No. 2 lamp 282. A No. 2 tension spring is arranged between the upper part of the insertion tube 24 and the mounting plate 23.

[0050] When the mounting plate 23 is connected to the placement plate 21, the mounting plate 23 drives the upper end of the insertion tube 24 thereon to pass through the clearance hole 221 and insert into the upper part of the placement plate 21, and makes the insertion tube 24 and the clearance hole 221 at the corresponding position coaxially arranged, so that the insertion tube 24 drives the triangular plate 26 through the square plate 25 to also be located directly above the position of the electronic component to be tested on the circuit board.

[0051] When electronic components are installed at positions on the circuit board where they are required, the circuit board drives the electronic components to move upward until they come into contact with the triangular plate 26, so that the electronic components push the square plate 25 upward through the triangular plate 26, thereby causing the square plate 25 to drive the insertion tube 24 thereon to move upward relative to the mounting plate 23, while stretching the No. 2 tension spring, thereby causing the electronic components of different heights on the circuit board to push the insertion tube 24 at the corresponding position upward.

[0052] The operator manually rotates the No. 2 screw 281 in advance, so that the No. 2 screw 281 drives the No. 2 micro switch 283 thereon to move up and down in the vertical direction to adjust the position, so that when all the electronic components start to push the square plate 25 to move upward, the square plate 25 moves to contact the No. 2 micro switch 283 at the corresponding position, causing the No. 2 micro switch 283 to operate, and then the No. 2 light 282 at the corresponding position is lit.

[0053] When the second light 282 is on, it means that an electronic component is installed at the corresponding mounting position on the circuit board. If no electronic component is installed at the corresponding mounting position on the circuit board, no electronic component can push the square plate 25 at the corresponding position to trigger the second micro switch 283, so that the second light 282 at the corresponding position is not lit.

[0054] See Figure 3 、 Figure 5 and Figure 6 The detection mechanism 2 also includes a straightening detection component 27 for detecting the verticality of the electronic component. The straightening detection component 27 includes a trigger plate 271 that is slidably arranged inside the triangular plate 26 in a direction perpendicular to the inclined surface. A coil spring is provided between the trigger plate 271 and the triangular plate 26. A chamfer is provided at the lower part of the trigger plate 271. A lamp No. 1 272 is fixedly installed on the side of the triangular plate 26 away from the insertion tube 24. A micro switch No. 1 273 for controlling the lamp No. 1 272 is fixedly installed inside the triangular plate 26. A follower column 274 for pressing the micro switch No. 1 273 is fixedly installed on the side of the trigger plate 271 away from the insertion tube 24. A synchronization part 275 is provided on the insertion tube 24.

[0055] See Figure 6 The synchronization part 275 includes two ear seat ring plates 2751 arranged up and down and rotatably set at the lower outer side of the insertion tube 24. The ear seat ring plates 2751 are hinged to a group of symmetrically arranged triangular plates 26 through hinged plates 2752 hinged on both sides thereof. A positioning pin 2753 is inserted and connected to the two ear seat ring plates 2751.

[0056] When it is necessary to inspect cylindrical electronic components, the operator inserts the positioning pins 2753 into the two ear seat ring plates 2751 at the same time, so that the two ear seat ring plates 2751 are locked into a whole, and the angles of the two ear seat ring plates 2751 are staggered by 90 degrees, so that the synchronous rotation of the two ear seat ring plates 2751 can drive the four triangular plates 26 in the corresponding positions to move synchronously through the hinged plates 2752 thereon.

[0057] When the square cylindrical electronic component needs to be inspected, the operator removes the positioning pins 2753 from the two ear seat ring plates 2751, so that the two ear seat ring plates 2751 rotate independently, thereby causing the two sets of symmetrically arranged triangular plates 26 to slide independently.

[0058] It should be noted that a torsion spring is provided between the two ear seat ring plates 2751 and the insertion tube 24. The torsion spring is not shown in the figure. In the initial state, the torsion spring drives the ear seat ring plate 2751 through its own elastic force to drive the ear seat ring plate 2751 to a position close to the axis of the insertion tube 24.

[0059] When the cylindrical electronic component contacts the triangular plate 26, the upper edge of the cylindrical electronic component slides along the inclined surface of the triangular plate 26 that it contacts first, and pushes the triangular plate 26 away from the axis of the insertion tube 24, so that all the triangular plates 26 are away from the axis of the insertion tube 24 at the same time. Then the upper edge of the cylindrical electronic component contacts the chamfer of the trigger plate 271 on the triangular plate 26 that contacts first, and pushes it to the inside of the corresponding triangular plate 26. The trigger plate 271 presses the number one micro switch 273 through the follower column 274 and lights up the number one light 272.

[0060] When the cylindrical electronic component is in a vertical state, the upper edge of the cylindrical electronic component can contact the inclined surfaces of the four triangular plates 26 at the same time, so that the four No. 1 lights 272 at the same square plate 25 are all lit. Conversely, when the cylindrical electronic component is in a skewed state, it is impossible for the four No. 1 lights 272 at the same square plate 25 to be all lit.

[0061] When the square-shaped electronic component contacts the triangular plate 26, the principle is the same as above, but the two sets of independently sliding triangular plates 26 can contact the long side and the short side of the upper end of the square-shaped electronic component respectively, so that the four edges of the upper end of the vertically arranged square-shaped electronic component can all contact the triangular plates 26 at the corresponding positions, that is, the four number one lights 272 on the same square plate 25 can be lit.

[0062] When all the second lights 282 and the first light 272 are lit, it is determined that all the electronic components on the circuit board have been installed and are installed vertically, that is, the test has passed; otherwise, the test has failed.

[0063] See Figures 1-6 When testing the induction cooker circuit board, the present invention also includes the following steps: In the first step, the operator manually rotates the four No. 1 screws 362 in advance, so that the No. 1 screws 362 drive the pushers 37 at the corresponding positions to adjust their positions through the track plate 361, so that the pushers 37 can push the circuit board to the specified position, and by adjusting the positions of the four pushers 37 respectively, circuit boards of different shapes can be pushed.

[0064] In the second step, the operator moves the mounting plate 23 from bottom to top until it fits on the lower side of the placement plate 21, and locks the mounting plate 23 and the placement plate 21 into a whole through the buckle 222. The operator then repeats the steps of connecting the mounting plate 23 to the placement plate 21 so that the mounting plate 23 can correspond to the top of each electronic component that needs to be tested.

[0065] In the third step, the operator places the circuit board on the upper side of the electric suction cup 34, and uses the electric suction cup 34 to adsorb the circuit board. Then, the telescopic section of the electric push rod 381 is extended to drive the pushing member 37 to push the circuit board to the specified position, so that the position of each electronic component to be inspected on the circuit board is located directly below the mounting plate 23 at the corresponding position. Then, the lifting plate 35 starts to drive the circuit board to move upward synchronously.

[0066] In the fourth step, the operator inserts or does not insert the positioning pin 2753 into the two ear seat ring plates 2751 at the same time according to the shape of the electronic component. Then the electronic component moves up to contact the triangular plate 26. The upper edge of the cylindrical electronic component slides along the inclined surface of the triangular plate 26 that it first contacts, and lights up the number one light 272 by pushing the trigger plate 271.
