[0001] This utility model relates to the field of control board processing technology, and more specifically, to a universal fixture for processing control boards of household appliances. Background Technology
[0002] With the booming development of the home appliance industry, the market demand for control boards, as core components of various home appliances, is increasing day by day. In the manufacturing process of control boards, fixtures play a crucial role. They can precisely fix the control board, ensuring its stable position during processing, thereby guaranteeing processing accuracy and product quality.
[0003] Traditional fixtures for processing control boards in household appliances lack versatility in their design. Their structure and dimensional parameters are typically fixed, only suitable for control boards within a specific size range. When processing control boards of different sizes, these fixtures cannot be used directly and must be replaced with matching specialized fixtures. This situation forces companies to maintain a large inventory of different types of fixtures during production, consuming significant storage space and increasing inventory management costs. Furthermore, switching and adjusting between different fixtures requires considerable time and manpower, reducing production continuity and efficiency. To address these problems, this device was invented. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a universal fixture for processing control boards of household appliances to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a general-purpose fixture for processing control boards of household appliances, comprising a frame, a fixed support mechanism, a movable clamping mechanism, a correction mechanism, and an adjustment mechanism;
[0006] The frame surface is provided with guide grooves;
[0007] The fixed support mechanism is fixedly installed on the frame and is used to support one side of the control panel of the household appliance.
[0008] The movable clamping mechanism is slidably mounted on the frame and can move relative to the fixed support mechanism to clamp the other side of the control panel of the household appliance.
[0009] The calibration mechanism is connected to the fixed support mechanism and is used to calibrate the position of the control panel of household appliances;
[0010] The adjusting mechanism is connected to the movable clamping mechanism and is used to drive the movable clamping mechanism to move in order to adjust the distance between the movable clamping mechanism and the fixed support mechanism.
[0011] Furthermore, the fixed support mechanism includes a No. 1 pad fixedly installed on one side of the top of the frame. A No. 1 placement groove is opened on the No. 1 pad, and a receiving groove is opened on the top of the No. 1 pad. A No. 1 double-rotating screw is rotatably installed on the top of the No. 1 pad. A No. 1 motor is installed on the No. 1 pad. The output shaft of the No. 1 motor is connected to the No. 1 double-rotating screw. Top moving blocks are threadedly connected to both sides of the No. 1 double-rotating screw. The width of the top moving blocks is equal to the width of the receiving groove. A No. 1 cylinder is fixedly installed at the bottom of the top moving blocks. A No. 1 pressure plate is connected to the end of the piston rod of the No. 1 cylinder.
[0012] Furthermore, the calibration mechanism includes a bracket connected to the first pad, a second double-rotating screw rotatably mounted on the top of the bracket, a handwheel fixedly mounted on one end of the second double-rotating screw, guide rods fixedly mounted on both sides of the second double-rotating screw on the top of the bracket, calibration plates threadedly connected to both sides of the second double-rotating screw, and the guide rods passing through both calibration plates.
[0013] Furthermore, the movable clamping mechanism includes a second pad, on which a second placement groove is provided. A second cylinder is fixedly installed at the middle position of the inner wall of the top of the second placement groove, and the piston rod of the second cylinder is connected to a second pressure plate.
[0014] Furthermore, rubber plates are fixedly installed on the side walls of both the No. 1 and No. 2 placement troughs.
[0015] Furthermore, the adjustment mechanism includes a single-direction screw rotatably mounted on the frame, a bottom moving block threaded onto the single-direction screw, a second motor mounted on the frame, the output shaft of the second motor connected to the single-direction screw, multiple mounting slots on both sides of the bottom moving block, rollers rotatably mounted in the mounting slots, and the rollers on both sides of the bottom moving block respectively contacting the side walls of the guide slots, and a second pad fixedly mounted on the top of the bottom moving block.
[0016] Furthermore, the sidewalls of the guide groove are provided with a wear-resistant coating.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The adjustment mechanism is driven by a second motor to rotate a single-direction screw, which moves the bottom moving block along the guide groove, thereby adjusting the distance between the movable clamping mechanism and the fixed support mechanism. This allows it to adapt to control boards of different sizes of household appliances, enhancing the versatility of the fixture and reducing the cost and hassle of frequently changing fixtures due to different control board sizes. The first motor in the fixed support mechanism drives a first double-direction screw to rotate, causing the top moving blocks on both sides to move in opposite directions during the rotation of the first double-direction screw, thereby adjusting the distance between the first pressure plates on both sides. This can limit one side of control boards of different sizes, further improving the fixture's adaptability to control boards of different sizes.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] See attached document Figures 1-4 This embodiment of a general-purpose fixture for processing control boards of household appliances includes a frame 1, a fixed support mechanism 2, a movable clamping mechanism 3, a correction mechanism 4, and an adjustment mechanism 5. The frame 1 provides a support base for the entire fixture.
[0030] See attached document Figures 1-3 A fixed support mechanism 2 is fixedly installed on the frame 1 to support one side of the control panel of the household appliance. The fixed support mechanism 2 includes a first platform 21 fixedly installed on one side of the top of the frame 1. The first platform 21 has a first mounting groove 22 and a receiving groove 23 on its top. A first double-rotational screw 24 is rotatably mounted on the top of the first platform 21. A first motor 25 is installed on the first platform 21, and the output shaft of the first motor 25 is connected to the first double-rotational screw 24. When in use, the first motor 25 is turned on, and its output shaft drives the first double-rotational screw 24 to rotate. Top moving blocks 26 are threadedly connected to both sides of the first double-rotational screw 24. The width of the top moving block 26 is equal to the width of the receiving groove 23, thereby limiting the top moving block 26 and allowing the top moving blocks 26 on both sides to move towards or away from each other during the rotation of the first double-rotating screw 24. A first cylinder 27 is fixedly installed at the bottom of the top moving block 26, and a first pressure plate 28 is connected to the end of the piston rod of the first cylinder 27. Adjusting the distance between the top moving blocks 26 on both sides adjusts the distance between the first pressure plates 28 on both sides, allowing the first pressure plates 28 on both sides to limit the control boards of different sizes of household appliances.
[0031] See attached document Figures 1-3 The calibration mechanism 4 includes a bracket 41 connected to the first platform 21. A second double-rotational screw 42 is rotatably mounted on the top of the bracket 41. A handwheel 43 is fixedly mounted on one end of the second double-rotational screw 42. When in use, rotating the handwheel 43 will rotate the second double-rotational screw 42. Guide rods 44 are fixedly mounted on both sides of the second double-rotational screw 42 on the top of the bracket 41. Calibration plates 45 are threadedly connected to both sides of the second double-rotational screw 42, and the guide rods 44 pass through the two calibration plates 45, thereby limiting the position of the calibration plates 45. This allows the two calibration plates 45 to move towards or away from each other during the rotation of the second double-rotational screw 42, thus calibrating the position of the household appliance control board.
[0032] See attached document Figure 1 and Figure 4The movable clamping mechanism 3 is slidably mounted on the frame 1 and can move relative to the fixed support mechanism 2 to clamp the other side of the household appliance control panel. The movable clamping mechanism 3 has a second pad 31, on which a second mounting groove 32 is provided. A second cylinder 33 is fixedly installed at the middle position of the inner wall of the top of the second mounting groove 32. The piston rod of the second cylinder 33 is connected to a second pressure plate 34.
[0033] See attached document Figure 4 Rubber plates 6 are fixedly installed on the side walls of the No. 1 placement slot 22 and the No. 2 placement slot 32. The rubber plates 6 play a buffering and protective role to prevent damage to the control board of household appliances during the clamping process.
[0034] See attached document Figures 1-4 The adjusting mechanism 5 is connected to the movable clamping mechanism 3 and is used to drive the movable clamping mechanism 3 to move in order to adjust the distance between the movable clamping mechanism 3 and the fixed support mechanism 2, thereby adapting to control panels of different sizes of household appliances. The adjustment mechanism 5 includes a single-direction screw 51 rotatably mounted on the frame 1, with a bottom moving block 52 threadedly connected to the single-direction screw 51. A second motor 53 is mounted on the frame 1, and the output shaft of the second motor 53 is connected to the single-direction screw 51. A guide groove 11 is provided on the surface of the frame 1. When in use, the second motor 53 is turned on, and the output shaft of the second motor 53 drives the single-direction screw 51 to rotate. Multiple mounting grooves 54 are provided on both sides of the bottom moving block 52, and rollers 55 are rotatably mounted in the mounting grooves 54. The rollers 55 on both sides of the bottom moving block 52 contact the side walls of the guide groove 11, thereby limiting the bottom moving block 52 and allowing the bottom moving block 52 to move along the guide groove 11 during the rotation of the single-direction screw 51. A second pad 31 is fixedly mounted on the top of the bottom moving block 52.
[0035] As an alternative, the sidewall of the guide groove 11 is provided with a wear-resistant coating, which can reduce the wear between the bottom moving block 52 and the guide groove 11 during movement and extend the service life of the equipment.
[0036] In this embodiment, the second motor 53 of the adjusting mechanism 5 is started according to the size of the control board of the household appliance to be processed. The output shaft of the second motor 53 drives the single-direction screw 51 to rotate. Since the rollers 55 on both sides of the bottom moving block 52 contact the side wall of the guide groove 11 of the frame 1 to achieve limit, the bottom moving block 52 moves along the guide groove 11. Since the second pad 31 is fixedly installed on the top of the bottom moving block 52, the second pad 31 will move together with the bottom moving block 52, thereby adjusting the movable clamping mechanism 3 and the fixed... The distance between the fixed support mechanisms 2 is adjusted to match the size of the control board. The household appliance control board is then placed between the first mounting slot 22 of the fixed support mechanism 2 and the second mounting slot 32 of the movable clamping mechanism 3. The rubber plates 6 on the side walls of the first and second mounting slots 22 and 32 provide cushioning and protection to prevent scratches on the control board surface. Next, the handwheel 43 of the calibration mechanism 4 is manually rotated. The handwheel 43 drives the second double-rotation screw 42 to rotate. The guide rods 44 on both sides of the second double-rotation screw 42 are positioned at the top of the bracket 41. The calibration plate 45 is limited, causing the two calibration plates 45 to move towards or away from each other during the rotation of the second double-rotation screw 42. This corrects the position of the household appliance control board placed on the fixture, ensuring accurate placement. Then, the first motor 25 of the fixed support mechanism 2 is activated. The output shaft of the first motor 25 drives the first double-rotation screw 24 to rotate. Since the width of the top moving block 26 is equal to the width of the top receiving groove 23 of the first pad 21, the top moving block 26 is limited. The movement of the two top moving blocks 26 will cause the control board to move towards the fixture. The first cylinder 27, which is fixedly installed at the bottom, and the first pressure plate 28 connected to the piston rod of the first cylinder 27 are moved to adjust the distance between the two first pressure plates 28, so that the two first pressure plates 28 limit one side of the control board. Then, the second cylinder 33 of the movable clamping mechanism 3 is activated, the piston rod of the second cylinder 33 extends, and drives the second pressure plate 34 connected to the piston rod of the second cylinder 33 to move downward to clamp the other side of the control board, thereby completing the stable clamping of the household appliance control board for subsequent processing operations.
[0037] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
