Description

Technical Field

[0001] This invention relates to the field of heater blade assembly and molding technology, specifically to a one-time press-fitting molding device for assembling heater blades. Background Technology

[0002] The louvered blades are the core plastic component for controlling the airflow direction of the heater, as shown in the instruction manual. Figure 1 As shown, the oscillating blade is formed by the interlocking and assembly of three parts: the air guide plate, the bushing, and the bracket.

[0003] Currently, most assembly fixtures in the industry are single-station structures, capable of pressing only one set of louver components at a time. In actual production, operators can only place the air guide plate, bushing, and bracket one by one, and only one finished product can be processed at a time. The process of feeding, pressing, and unloading is cumbersome and time-consuming, resulting in low hourly capacity of the equipment. It is difficult to match the continuous production rhythm of the heater assembly line, and the overall utilization rate of the equipment is low. Summary of the Invention

[0004] The purpose of this invention is to provide a one-time press-fitting device for assembling heater blades, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a one-time press-fitting molding device for assembling the rotor blades of a heater, used for press-fitting the air guide plate, bushing, and bracket of the rotor blades; comprising: carrier; A mold is disposed on the carrier; the mold has a plurality of first slots extending along a first direction; the mold has at least two second slots extending along a second direction; the second direction is perpendicular to the first direction; the plurality of first slots are equidistantly distributed along the second direction; the second slots and the first slots are arranged in a cross shape; the first slots are used to place air guide plates; the second slots are used to place bushings or brackets. A pressing mechanism is arranged opposite to the mold along a third direction, which is perpendicular to the first direction and the second direction; the pressing mechanism is configured to apply pressure along the third direction to the air guide plate in the first slot, so that the air guide plate engages with the bushing and bracket.

[0006] As a further embodiment of the present invention, the pressing mechanism includes a pressure plate arranged opposite to the mold along the third direction, and a linear drive member for driving the pressure plate to reciprocate along the third direction; the projections of the first slot and the second slot in a plane perpendicular to the third direction are located within the projection area of ​​the pressure plate in that plane; the linear drive member includes a fixed end and a power output end capable of reciprocating relative to the fixed end along the third direction; the power output end is fixed to the pressure plate.

[0007] As a further embodiment of the present invention, the linear drive component is one of a cylinder, a hydraulic cylinder, or a linear motor.

[0008] As a further embodiment of the present invention, the fixed end is fixedly connected to the carrier via a frame.

[0009] As a further embodiment of the present invention, a correction mechanism is provided on the side of the first slot; the correction mechanism is configured to adjust the position of the air guide plate located in the first slot so that the air guide plate can engage with the bushing and bracket in an attitude parallel to the third direction.

[0010] As a further embodiment of the present invention, the correction mechanism includes two guide rollers respectively disposed on both sides of the first slot in the second direction; and a drive unit for driving the two guide rollers to move toward or away from each other; the axis of the guide rollers is parallel to the first direction and is rotatable relative to the mold.

[0011] As a further embodiment of the present invention, the driving unit includes two sliders that slide in cooperation with the mold in the second direction, and the two sliders are rotatably connected to the guide roller respectively; a connecting rod is hinged to the end of the slider away from the guide roller, and a sliding rod is hinged to the end of the connecting rod away from the slider, and the sliding rod slides in cooperation with the mold in the third direction upward; the sliding rod is connected to a linear drive component two for driving it to reciprocate upward in the third direction.

[0012] As a further aspect of the present invention, the first slot has a trapezoidal shape with a narrower top and a wider bottom in the cross-section of a plane perpendicular to the first direction.

[0013] As a further embodiment of the present invention, the second slot is provided with a support plate that slides and engages with the mold in the third direction. The support plate is connected to a linear drive member for driving it to reciprocate along the third direction. The support plate is slidably connected to two clamping blocks in the second direction, and the clamping blocks are connected to springs for resetting. The second slot is provided with a wedge block. When the support plate moves towards the wedge block in the second slot, the wedge block can drive the two clamping blocks to move towards each other to adjust the position of the bushing or bracket.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

The pressing mechanism covers all work stations, and multiple air guide plates can be engaged with the bushing and bracket with one press, which can effectively improve the assembly efficiency of the blades.

[0015] 2. Through the setting of the correction mechanism, after the air guide plate is placed into the first slot, the linear drive component two drives the slide rod to move upward along the third direction Z. The slide rod pushes the two side sliders to move synchronously towards each other through the connecting rod, so that the two side guide rollers move synchronously towards the side closer to the air guide plate. After the two guide rollers clamp the air guide plate, the air guide plate can be placed in the center position of the first slot. At the same time, the air guide plate can be in a state parallel to the third direction Z, which effectively avoids the air guide plate from shifting, misaligning, or being subjected to force on one side during the pressing process. At the same time, the guide rollers can rotate, which can reduce the friction between them and the air guide plate and reduce the risk of scratching the workpiece surface.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 The technical solution of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1-3 An embodiment of the present invention provides a one-time press-fitting device for assembling the oscillating blades of a heater, used for press-fitting the air guide plate 71, bushing 72, and bracket 73 of the oscillating blades; comprising: a carrier 10; a mold 20 disposed on the carrier 10; the mold 20 having a plurality of first slots 21 extending along a first direction; the mold 20 having at least two second slots 22 extending along a second direction; the second direction being perpendicular to the first direction; the plurality of first slots 21 being equidistantly distributed along the second direction; the second slots 22 being arranged in a cross shape with the first slots 21; the first slots 21 being used to place the air guide plate; the second slots 22 being used to place the bushing or bracket; a press-fitting mechanism 30 being arranged opposite to the mold 20 along a third direction, the third direction being perpendicular to the first and second directions; the press-fitting mechanism 30 being configured to apply pressure along the third direction to the air guide plate in the first slot 21, so that the air guide plate is engaged with the bushing and bracket.

[0021] In this embodiment, the first direction, the second direction, and the third direction are defined to be perpendicular to each other, and taking the first and second directions as being located in a horizontal plane as an example, the third direction is set vertically. For ease of understanding, as follows... Figure 2 As shown, the positive or negative direction of the X-axis is the first direction, the positive or negative direction of the Y-axis is the second direction, and the positive or negative direction of the Z-axis is the third direction.

[0022] In this embodiment, the mold 20 is injection molded and fixed to the carrier 10 with bolts. When pressing the blades, the bushing 72 and the bracket 73 are first placed in the two second slots 22 respectively, and then a guide plate 71 is placed in each first slot 21. Then the pressing mechanism applies downward pressure to the guide plate 71, so that the guide plate 71 is inserted into the bushing 72 and the bracket 73. Then the pressed blades are taken out from the mold. In this embodiment, the cross-shaped first slots 21 and second slots 22 are set up, and multiple guide plates can be arranged simultaneously at one time. The pressing mechanism 30 covers all stations, and multiple guide plates can be engaged with the bushing and the bracket with one press, which can effectively improve the assembly efficiency of the blades.

[0023] Please see Figure 2 and Figure 4 In an optional embodiment of the present invention, the pressing mechanism 30 includes a pressure plate 31 arranged opposite to the mold 20 along a third direction, and a linear drive member 32 for driving the pressure plate 31 to reciprocate along the third direction; the projections of the first slot 21 and the second slot 22 in a plane perpendicular to the third direction are located within the projection area of ​​the pressure plate 31 in the plane; the linear drive member 32 includes a fixed end 321 and a power output end 322 capable of reciprocating relative to the fixed end 321 along the third direction; the power output end 322 is fixed to the pressure plate 31; the linear drive member 32 is one of a cylinder, a hydraulic cylinder, or a linear motor. It should be understood that the pressure plate 31 is located directly above the mold and covers the entire mold 20; the bushing 72 and the bracket 73 are placed in the second slot 22, and after the air guide plate 71 is placed in the first slot 21, the power output end 322 of the linear drive component 32 drives the pressure plate 31 to move downward along the third direction Z. The pressure plate 31 applies downward pressure to the air guide plate 71, so that all the air guide plates 71 can move vertically downward along the third direction Z and be inserted into the bushing 72 and the bracket 73. In this embodiment, the linear drive component 32 is preferably a cylinder. The cylinder has a small overall volume and light weight, and does not require a heavy support base. Moreover, the cylinder has a fast response speed for extension and retraction, and can quickly complete the entire set of actions of pressing down and holding pressure and lifting and resetting, which can further improve the assembly efficiency of the swing blade.

[0024] Please see Figure 2 In an optional embodiment of the present invention, the fixed end 321 is fixedly connected to the carrier 10 via the frame 40. It should be understood that in this embodiment, the frame 40 is composed of multiple vertical pipes and multiple horizontal pipes. When the linear drive component 32 is preferably a cylinder, the linear drive component 32 does not require a heavy support base, and the vertical and horizontal pipes can be made of plastic pipes with suitable wall thickness, which can greatly reduce the cost of the press-fitting device.

[0025] Please see Figures 5-6In an optional embodiment of the present invention, a correction mechanism is provided on the side of the first slot 21; the correction mechanism is configured to adjust the position of the air guide plate located in the first slot 21 so that the air guide plate can engage with the bushing and bracket in an attitude parallel to the third direction; the correction mechanism includes two guide rollers 51 respectively provided on both sides of the first slot 21 in the second direction; and a drive unit for driving the two guide rollers 51 to move towards or away from each other; the axis of the guide rollers 51 is parallel to the first direction and can rotate relative to the mold 20; the drive unit includes two sliders 52 that slide in cooperation with the mold 20 in the second direction, and the two sliders 52 are rotatably connected to the guide rollers 51 respectively; a connecting rod 53 is hinged to the end of the slider 52 away from the guide roller 51, and a sliding rod 54 is hinged to the end of the connecting rod 53 away from the slider 52, and the sliding rod 54 slides in cooperation with the mold 20 in the third direction; the sliding rod 54 is connected to a linear drive member 2 for driving it to reciprocate in the third direction. It should be understood that, considering that in order to facilitate the insertion of the air guide plate 71 into the first slot 21, the width of the first slot 21 in the second direction Y should be greater than the width of the air guide plate 71, that is, the air guide plate 71 and the first slot 21 are in a clearance fit. If the clearance between the air guide plate 71 and the first slot 21 is set too small, it will increase the difficulty of inserting the air guide plate 71 into the first slot 21. If the clearance between the air guide plate 71 and the first slot 21 is set too large, it will be difficult to insert the air guide plate 71 into the first slot 21. The air guide plate 71 is prone to tilting and shifting left and right, causing misalignment at the end where it engages with the bushing 72 and bracket 73. This increases the difficulty of alignment and assembly, leading to issues such as incomplete engagement of the clips and loosening of the assembly. Furthermore, when the pressing mechanism applies vertical pressure to the air guide plate 71, the tilted and shifted air guide plate 71 will bear uneven lateral forces, posing a risk of cracking or deformation to the plastic material. During operation, the straightening mechanism places the air guide plate 71 into… After the first slot 21, the second linear drive unit drives the slide bar 54 to move upward along the third direction Z. The slide bar 54 pushes the two sliders 52 on both sides to move synchronously towards each other through the connecting rod 53, so that the two guide rollers 51 on both sides move synchronously towards the side closer to the air guide plate 71. After the two guide rollers 51 clamp the air guide plate 71, the air guide plate 71 can be placed in the center position of the first slot 21. At the same time, the air guide plate 71 can be in a state parallel to the third direction Z, effectively avoiding the air guide plate 71 from shifting, misaligning or being subjected to force on one side during the pressing process. At the same time, the guide rollers 51 can rotate, which can reduce the friction between them and the air guide plate 71 and reduce the risk of scratching the workpiece surface. After the pressing is completed, the second linear drive unit drives the slide bar 54 to move in the opposite direction, and the connecting rod 53 drives the two sliders 52 on both sides to move synchronously in opposite directions. The guide rollers 51 release the air guide plate 71, so that the assembled swing blade assembly can be smoothly removed. This can effectively improve the positioning accuracy of the air guide plate 71 before pressing, improve the pressing and clamping quality, and reduce the product defect rate.

[0026] Please see Figures 5-6In an optional embodiment of the present invention, the first slot 21 has a trapezoidal shape with a narrower top and a wider bottom in cross-section on a plane perpendicular to the first direction. It should be understood that in this embodiment, the first slot 21 is set to a trapezoidal shape with a narrower top and a wider bottom. Only the narrow upper side of the first slot 21 provides initial guidance for the air guide plate 71. The lower space of the first slot 21 is widened, so that a gap is formed between the main body of the air guide plate 71 and the groove wall of the first slot 21, which significantly reduces the sliding friction when the air guide plate 71 moves vertically and avoids damage to the appearance of the workpiece. At the same time, the loose lower space can reduce the lateral restraint of the groove wall on the air guide plate 71, and the correction mechanisms on both sides of the first slot 21 can complete the centering correction of the air guide plate with a smaller thrust.

[0027] Please see Figures 7-9 In an optional embodiment of the present invention, a support plate 61 is provided in the second slot 22, which slides and engages with the mold 20 in the third direction. The support plate 61 is connected to a linear drive component for driving its reciprocating movement in the third direction. Two clamping blocks 62 are slidably connected to the support plate 61 in the second direction, and springs 63 for resetting are connected to the clamping blocks 62. A wedge block 64 is provided in the second slot 22. When the support plate 61 moves towards the wedge block 64 in the second slot 22, the wedge block 64 can drive the two clamping blocks 62 to move towards each other to adjust the position of the bushing or bracket. It should be understood that in order to facilitate the insertion of the bushing 72 and bracket 73 into the second slot 22, the slot needs to reserve an assembly gap. If the gap is too large, the workpiece is prone to offset and misalignment in the second direction after placement, resulting in misalignment of its snap-fit ​​structure with the upper air guide plate 71, and causing problems such as poor snap-fit ​​and assembly failure. In this embodiment, the bushing 72 and the bracket 73 can be placed on the bearing surface of the support plate 61 through the setting of the support plate 61. Then, the linear drive component 3 drives the support plate 61, bushing 72, and bracket 73 to move into the depth of the second slot 22. The bearing surface of the support plate 61 is close to the top surface of the mold 20, which can facilitate the placement of the bushing 72 and the bracket 73. When the clamping block 62 contacts the wedge block 64, the wedge surface of the wedge block 64 drives the clamping block 62 to move closer to the bushing 72 and the bracket 73. The wedge block 64 pushes the clamping blocks 62 on both sides to synchronously correct and clamp the bushing 72 and the bracket 73. The workpiece is continuously and stably clamped by the self-locking of the wedge block 64.

[0028] In the embodiments of the present invention, linear drive component two and linear drive component three are both one of cylinder, hydraulic cylinder and linear motor, which are not specifically shown in the accompanying drawings.
