Description

Technical Field

[0001] The present invention relates to an automation device, in particular to an upper molding device. Background Art

[0002] The interplay of a bezel and a fillet is a common method of fitting. This type of fit generally requires minimal precision, and the fit is typically an interference fit. This type of fit is often used for clamping, particularly for thin, easily deformable materials like films and sheets. For example, if sheet B is to be placed on object A, a bezel can be created in object A, with sheet B partially covering the bezel. Then, a suitable fillet is prepared and a portion of sheet B, along with the fillet, is pressed into the bezel.

[0003] The common raw material for molding is rubber strips, which have good flexibility and elasticity. However, many existing moldings are installed manually, which is inefficient and has high labor costs. Summary of the Invention

[0004] The present invention provides a fully automatic and efficient molding strip installation device, which solves the problem of low efficiency in installing molding grooves and molding strips in the prior art.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a top molding device, suitable for moldings made of flexible materials, characterized by comprising: a molding groove positioning mechanism for fixing an article provided with a molding groove, the article hereinafter referred to as a semi-finished product;

[0006] Upper molding mechanism, which can press the molding into the molding groove;

[0007] A frame, used for carrying the embedding groove positioning mechanism and the upper embedding strip mechanism;

[0008] A moving mechanism, the moving mechanism being provided on the frame and being used to adjust the relative position of the upper molding mechanism and the molding groove positioning mechanism;

[0009] The upper molding mechanism includes: a conveying mechanism for conveying and guiding the molding; a cutting mechanism for cutting the molding into a fixed length; an embedding guide wheel, wherein the conveying mechanism can convey the cut molding into the guide groove of the embedding guide wheel, and the embedding guide wheel can press the molding into the embedding groove;

[0010] The upper molding mechanism and the embedding groove positioning mechanism are relatively displaced under the drive of the moving mechanism, so that the embedding guide wheel moves relatively along the path of the embedding groove, the conveying mechanism continuously conveys the molding, and the embedding guide wheel can continuously press the molding into the embedding groove.

[0011] The operating principle of the present invention is as follows: in the initial state, a semi-finished product is fixed on the embedding groove positioning mechanism, and an embedding strip is passed through the upper embedding strip mechanism. The embedding strip enters from the inlet side of the conveying mechanism and is output from the outlet side of the conveying mechanism. The front end of the embedding strip is conveyed by the conveying mechanism to the guide groove of the embedding guide wheel;

[0012] During the action phase, the moving mechanism on the frame begins adjusting the relative positions of the upper molding mechanism and the molding groove positioning mechanism, moving the molding guide wheel to the molding groove starting point of the semi-finished product. The molding guide wheel can press the molding into the molding groove starting point. The conveying mechanism operates continuously, and the moving mechanism and the molding groove positioning mechanism cooperate to move, causing the molding guide wheel to move relative to each other along the molding groove path. In this way, the molding can be continuously pressed into the molding groove. The cutting mechanism can cut the molding into the required length. After completing the molding process for a semi-finished product, the moving mechanism controls the molding upper molding mechanism to separate from the molding groove positioning mechanism, facilitating the replacement of the semi-finished product. The present invention can efficiently complete the molding process and improve production efficiency.

[0013] Furthermore, the movement mechanism includes: a first sliding block capable of sliding horizontally relative to the frame; a second sliding block that slides vertically in conjunction with the first sliding block; a first power unit mounted on the frame for driving the first sliding block; and a second power unit mounted on the first sliding block for driving the second sliding block up and down; the upper molding mechanism is entirely fixed to the second sliding block, and the first sliding block can drive the upper molding mechanism toward or away from the molding groove positioning mechanism. In this manner, the movement mechanism can drive the entire upper molding mechanism to move in two axial directions. The first and second power units can be existing linear propulsion mechanisms such as cylinders and linear motors.

[0014] The present invention further provides an upper fillet device suitable for an annular fillet groove, including an upper fillet device, characterized in that the fillet groove positioning mechanism includes:

[0015] A lower positioning plate, the lower positioning plate is rotatably connected to the frame, and the rotating shaft is vertically arranged;

[0016] The upper positioning plate can be mounted on the lower positioning plate from the upper side and rotates coaxially with the lower positioning plate. The upper and lower positioning plates together secure the semi-finished product. The embedding grooves on the semi-finished product are circular, with the center of the groove concentric with the rotating axis. This design allows the continuously conveyed molding to be embedded in the embedding groove while driving the entire embedding positioning mechanism to rotate, while the embedding guide wheel remains stationary, completing the entire embedding process.

[0017] Furthermore, the conveying mechanism includes a guide wheel assembly and a conduit. The conduit is fixed to the second sliding block. The guide wheel assembly guides and pushes the fillet to the inlet end of the conduit. The fillet extends from the outlet end of the conduit and enters the lower side of the embedded guide wheel. The cutting mechanism includes a first cylinder and a blade. The conduit is provided with a notch. The first cylinder pushes the blade through the notch to cut the fillet. Guiding the fillet through the conduit provides better results and higher precision.

[0018] Furthermore, the guide wheel group includes a first guide wheel, a second guide wheel, a first pressure wheel and a second pressure wheel. The rotating shafts of the first guide wheel and the second guide wheel are fixed on the second sliding block. The first pressure wheel is located directly above the first guide wheel. A counterweight block is fixed to the first pressure wheel, and the counterweight block slides up and down with the second sliding block; the second pressure wheel is connected to a second cylinder, which is fixed on the second sliding block. The second cylinder can push the second pressure wheel to move downward until it abuts against the second guide wheel; the second sliding block is provided with a stepper motor, which can drive the second guide wheel to rotate.

[0019] The strip first flows between the first guide wheel and the first pressure wheel. Under the weight of the counterweight, the first pressure wheel secures the strip, preventing it from escaping the guide groove on the first guide wheel. The first pressure wheel's height flexibility also makes it highly versatile. The strip experiences relatively high pressure between the second guide wheel and the second pressure wheel. Because the second guide wheel is the driving wheel, it must continuously convey the strip, increasing friction by increasing the extrusion force. When the strip-loading mechanism stops working, the second cylinder lifts off the second pressure wheel to prevent deformation caused by prolonged clamping. The second guide wheel is driven by a stepper motor, whose rotational range can be set per movement, effectively controlling the feed rate of the strip each time it is loaded. This feed rate corresponds to the cutting length of the shearing mechanism.

[0020] Furthermore, the first pressing wheel is a one-way bearing, which prevents the fillet from being pulled in the opposite direction and causing displacement of the fillet in the conveying mechanism, resulting in insufficient length of the cut fillet.

[0021] Furthermore, the guide groove of the second guide wheel is provided with a plurality of anti-skid holes distributed in an array. When the fillet passes between the second guide wheel and the second pressure wheel, the pressure will compel the fillet to deform into the anti-skid holes. The slight deformation will increase the friction and prevent slipping.

[0022] Furthermore, a third cylinder is fixed vertically on the frame and above the lower positioning plate, and the third cylinder can drive the upper positioning plate to move up and down.

[0023] Furthermore, the lower positioning plate is overall conical in shape, and is suitable for processing conical semi-finished products.

[0024] Furthermore, the lower surface of the upper positioning plate matches the upper surface of the lower positioning plate, and a plurality of rubber bands arranged in a network are connected to the lower surface of the upper positioning plate. When the upper and lower positioning plates are closed, the rubber bands will press tightly against the upper surface of the semi-finished product to prevent the upper structure of the semi-finished product from shifting.

[0025] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The strip-uppering mechanism and the groove-engraving positioning mechanism are relatively displaced under the drive of the moving mechanism, so that the embedding guide wheel moves relatively along the path of the groove, the conveying mechanism continuously conveys the strip, and the embedding guide wheel continuously presses the strip into the groove, thereby realizing an automatic strip-upping process; 2. The groove-engraving positioning mechanism is designed to be passively rotatable, so that when the embedding guide wheel remains fixed, the continuously conveyed strip can be embedded in the groove while pushing the groove-engraving positioning mechanism to rotate as a whole, thereby completing the entire strip-upping process for the groove.

[0032] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0034] Example 1: See Figure 1 、 Figure 2 and Figure 3 A top molding device is used to process a conical hat. The top surface of the hat is provided with a circular molding groove and is also covered with a film. The molding groove is used to press the film into the molding groove to achieve the purpose of fixing the film. The top molding device includes: a molding groove positioning mechanism 100 for fixing an article provided with the molding groove, which is hereinafter referred to as a semi-finished product;

[0035] The upper molding mechanism 200 can press the molding into the molding groove;

[0036] The frame 300 is used to support the groove positioning mechanism 100 and the upper molding mechanism 200;

[0037] A moving mechanism 400 , which is disposed on the frame 300 and can be used to adjust the relative position of the upper molding mechanism 200 and the molding positioning mechanism 100 ;

[0038] The upper molding mechanism 200 includes: a conveying mechanism 210 for conveying and guiding the molding; a cutting mechanism 220 for cutting the molding into a fixed length; and an embedding guide wheel 230. The conveying mechanism 210 can convey the cut molding into the guide groove of the embedding guide wheel 230, and the embedding guide wheel 230 can press the molding into the embedding groove.

[0039] The slot positioning mechanism 100 includes: a conical lower positioning plate 110, which is rotatably connected to the frame 300, with the rotating shaft being vertically arranged; an annular upper positioning plate 120, which can be mounted on the lower positioning plate 110 from the upper side. The upper positioning plate 120 can be synchronously and coaxially rotated with the lower positioning plate 110, and the semi-finished product is fixed between the lower positioning plate and the upper positioning plate;

[0040] The upper molding mechanism 200 is driven by the moving mechanism 400 to move the embedding guide wheel 230 to above the embedding groove on the semi-finished product. The conveying mechanism 210 continuously conveys the molding, and the embedding guide wheel 230 can continuously press the molding into the embedding groove.

[0041] The operating principle of this embodiment is as follows: in the initial state, a semi-finished product is fixed to the inlay groove positioning mechanism, and a molding strip is passed through the upper molding strip mechanism. The molding strip enters from the inlet side of the conveying mechanism and is output from the outlet side of the conveying mechanism. The front end of the molding strip is conveyed by the conveying mechanism to the guide groove of the embedding guide wheel;

[0042] During the operation phase, the moving mechanism on the frame begins adjusting the relative positions of the strip-loading mechanism and the slot-loading positioning mechanism, moving the insertion guide wheel to the starting point of the semi-finished product's slot. The insertion guide wheel presses the strip into the slot at that point, and the conveying mechanism operates continuously. While the insertion guide wheel remains stationary, the continuously conveyed strip is inserted into the slot while simultaneously pushing the slot-loading positioning mechanism to rotate, completing the entire strip-loading process. The shearing mechanism cuts the strip to the desired length. After completing the strip-loading process for a semi-finished product, the moving mechanism controls the strip-loading mechanism to separate from the slot-loading positioning mechanism, allowing the semi-finished product to be replaced. This embodiment efficiently completes the strip-loading process, improving production efficiency.

[0043] See Figure 2 and Figure 4 The moving mechanism 400 includes a first sliding block 410 and a second sliding block 420. A first slide rail 310 is provided on the frame 300, and the first sliding block 410 slidably engages with the first slide rail 310. A second vertically disposed second slide rail 430 is provided on the first sliding block 410, and the second sliding block 420 slidably engages with the second slide rail 430. A first power unit 320 is provided on the frame 300 to propel the first sliding block 410, and a second power unit 440 is provided on the first sliding block 410 to propel the second sliding block 420 up and down. The upper molding mechanism 200 is entirely fixed to the second sliding block 420, and the first sliding block 410 can drive the upper molding mechanism 200 toward or away from the molding groove positioning mechanism 100. In this way, the moving mechanism can drive the upper molding mechanism as a whole to move in two axial directions. The first and second power units are cylinders.

[0044] See Figure 2 and Figure 3 The conveying mechanism 210 includes a guide wheel assembly 211 and a guide tube 212. The guide tube 212 is fixed to the second sliding block 420. The guide wheel assembly 211 guides the strip to the inlet end of the guide tube 212. The strip extends from the outlet end of the guide tube 212 and enters the lower side of the embedding guide wheel 230. The cutting mechanism 220 includes a first cylinder 221 and a blade 222. The guide tube 212 is provided with a notch 2121. The first cylinder 221 pushes the blade 222 through the notch 2121 to cut the strip. Guiding the strip through the guide tube provides better results and higher precision.

[0045] See Figure 1 、 Figure 2The guide wheel group 211 includes a first guide wheel 2111, a second guide wheel 2112, a first pressure wheel 2113 and a second pressure wheel 2114. The rotating shafts of the first guide wheel 2111 and the second guide wheel 2112 are fixed on the second sliding block 420. The first pressure wheel 2113 is located directly above the first guide wheel 2111. A counterweight block 2115 is fixed to the first pressure wheel 2113, and the counterweight block 2115 slides up and down with the second sliding block 420; the second pressure wheel 2114 is connected to a second cylinder 2116, and the second cylinder 2116 is fixed on the second sliding block 420. The second cylinder 2116 can push the second pressure wheel 2114 to move downward until it abuts against the second guide wheel 2112; the second sliding block 420 is provided with a stepping motor 421, and the stepping motor can drive the second guide wheel 2112 to rotate.

[0046] The strip first flows between the first guide wheel and the first pressure wheel. Under the weight of the counterweight, the first pressure wheel secures the strip, preventing it from escaping the guide groove on the first guide wheel. The first pressure wheel's height flexibility also makes it highly versatile. The strip experiences relatively high pressure between the second guide wheel and the second pressure wheel. Because the second guide wheel is the driving wheel, it must continuously convey the strip, increasing friction by increasing the extrusion force. When the strip-loading mechanism stops working, the second cylinder lifts off the second pressure wheel to prevent deformation caused by prolonged clamping. The second guide wheel is driven by a stepper motor, whose rotational range can be set per movement, effectively controlling the feed rate of the strip each time it is loaded. This feed rate corresponds to the cutting length of the shearing mechanism.

[0047] The first pressing wheel 2113 is a one-way bearing, which prevents the strip from being pulled in the opposite direction and causing displacement of the strip in the conveying mechanism, resulting in insufficient length of the cut strip.

[0048] See Figure 6 The guide groove of the second guide wheel 2112 is provided with a plurality of anti-skid holes 2117 distributed in an array. When the fillet flows between the second guide wheel and the second pressure wheel, the pressure will compress the fillet to deform into the anti-skid holes. The slight deformation will increase the friction and prevent slipping.

[0049] See Figure 4 A third cylinder 330 is fixed vertically on the frame 300 and above the lower positioning plate. The third cylinder 330 can drive the upper positioning plate 120 to move up and down.

[0050] See Figure 5 The lower surface of the upper positioning plate 120 matches the upper surface of the lower positioning plate 110. A plurality of rubber bands 121 arranged in a network are connected to the lower surface of the upper positioning plate 120. When the upper and lower positioning plates are closed, the rubber bands will press tightly against the upper surface of the semi-finished product, preventing the upper structure of the semi-finished product from shifting.
