Description

Technical Field

[0001] The invention relates to the technical field of double-sided adhesive tape, and in particular to a double-sided adhesive tape device for a bathroom door glass support strip. Background Art

[0002] In daily life, support strips are needed in the process of installing bathroom glass doors. At present, the general installation method of bathroom glass doors is: stick double-sided tape around the glass → tear off the isolation paper of the double-sided tape → put a support strip of a certain height → stick double-sided tape around the support strip → tear off the isolation paper of the double-sided tape on the support strip → put the second piece of glass. However, in order to make the double-sided tape adhere more tightly, you need to pay attention to the following conditions: 1. Clean the surface: Make sure the surface of the adherend is clean, dry, and free of dust, grease, moisture or other impurities. You can use a mixture of isopropyl alcohol and water to wipe it, and then wait for the surface to dry completely; 2. Apply appropriate pressure: After sticking the double-sided tape, use a roller or other means to apply a pressure of about 15 psi (1.05 kg / cm2) to make it fully contact with the adherend and enhance the bonding strength; 3. Choose the right temperature: Generally speaking, the ideal temperature for pasting is 15-38°C, not less than 10. The bonding performance is usually better in a high temperature environment, but it depends on the type and characteristics of the double-sided tape.

[0003] The existing method is generally to directly place the support strip on the operating table, and then directly stick the double-sided tape on the side of the support strip. Generally, the surface of the support strip is not cleaned before sticking. In this way, if there is dust or other impurities on the surface of the support strip, the sticking process is carried out without cleaning, which will affect the adhesion of the subsequent double-sided tape.

[0004] Therefore, a double-sided adhesive device for a bathroom door glass support strip is proposed. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a double-sided adhesive device for a bathroom door glass support strip.

[0010] Furthermore, in the present invention, the expansion unit includes a plurality of expansion rings abutting against each other and arranged on the inner wall of the outer telescopic tube, the expansion ring close to the first grinding wheel is connected to the first grinding wheel, and the expansion ring close to the second grinding wheel is connected to the second grinding wheel.

[0011] Furthermore, in the present invention, the cleaning mechanism also includes a dust blowing mechanism arranged on the workbench. The number of the dust blowing mechanisms is two groups. The two groups of dust blowing mechanisms are respectively located on both sides of the support bar. The driving ends of the two groups of dust blowing mechanisms are transmission connected to the rotating shaft. The wind blown out through the air outlets of the two groups of dust blowing mechanisms is blown toward the two side walls of the support bar that are perpendicular to the workbench.

[0012] Furthermore, in the present invention, any of the above-mentioned dust blowing mechanisms includes a push rod, a piston and an air jet pipe connected in sequence and arranged on the above-mentioned workbench, and the wind blown out through the above-mentioned air jet pipe is blown toward the side wall of the above-mentioned support bar that is perpendicular to the above-mentioned workbench; the above-mentioned rotating shaft is a crankshaft, and two connecting rod journals are arranged on the above-mentioned rotating shaft at intervals, and the end of the above-mentioned push rod away from the above-mentioned piston is rotatably connected to the corresponding above-mentioned connecting rod journal.

[0013] Furthermore, in the present invention, the Z-axis limiting mechanism includes at least one limiting cylinder, the limiting cylinder is located above the travel direction of the supporting bar, and both ends of the limiting cylinder are connected to the workbench through brackets.

[0016] The beneficial effects of the present invention are: 1.

During the movement of the support strip on the workbench, the rotation of the shaft drives the first grinding wheel and the second grinding wheel to rotate. The first grinding wheel and the second grinding wheel are always in contact with the two side walls of the support strip under the action of the metal spring. The continuous contact between the first grinding wheel and the second grinding wheel and the two side walls of the support strip can clean the impurities on the two side walls of the support strip that are perpendicular to the workbench; at the same time, the continuous contact between the first grinding wheel and the second grinding wheel and the two side walls of the support strip will generate friction.

An adjustment mechanism for adjusting the expansion and contraction amount of the metal spring installed on the rotating shaft can conveniently adjust the expansion and contraction amount (elastic force) of the metal spring between the two grinding wheels, so that when support bars of different widths within a certain size range are clamped between the two grinding wheels, the clamping force of the two grinding wheels on the support bars under the action of the metal spring is relatively appropriate, so that the metal spring can achieve the clamping effect when achieving the clamping effect, and realize the cleaning and heating of the two side walls of the support bar perpendicular to the workbench, without affecting the smooth movement of the support bar on the workbench; 3. The rotating shaft is designed as a crankshaft. In this way, during the rotation of the rotating shaft, the two pistons repeatedly push the air in the two jet pipes under the action of the two push rods, so that the air in the two jet pipes blows toward the two side walls perpendicular to the support bar and the workbench at a certain speed. This wind can further remove dust from the two side walls perpendicular to the support bar and the workbench, further improving the cleanliness of the two side walls perpendicular to the support bar and the workbench; 4. The workbench, Z-axis limit mechanism and X-axis limit mechanism are used together to limit the freedom of movement of the support strip on the workbench, so that the support strip can only move in one direction, reducing the probability of the double-sided tape not being able to stick straight during the pasting process.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-3 , the present invention provides a technical solution: A device for sticking double-sided tape on a glass support strip of a bathroom door comprises a workbench 101 and a support strip 201 placed on the workbench 101, wherein the cross section of the support strip 201 is rectangular; a cleaning mechanism, a Z-axis limiting mechanism, a gluing mechanism and an X-axis limiting mechanism are sequentially arranged on the workbench 101 along the moving direction of the support strip 201, wherein the cleaning mechanism is used for cleaning two side walls of the support strip 201 which are perpendicular to the workbench 101; and the gluing mechanism is used for sticking the double-sided tape 1001 on the two side walls of the support strip 201 which are perpendicular to the workbench 101.

[0021] like Figure 1-Figure 3 As shown, in this embodiment, the moving direction of the support bar 201 is the Y-axis direction.

[0022] Specifically, the cleaning mechanism includes a rotating shaft 301 located above the support bar 201, a first grinding wheel 302 fixedly disposed on the rotating shaft 301, and a second grinding wheel 303 slidably and sealedly connected to the rotating shaft 301. One end of the rotating shaft 301 is connected to a driving mechanism, which can be a motor. The rotating shaft 301 is connected to the workbench 101 through two brackets, and the rotating shaft 301 is rotatably connected to the two brackets, and the central axis of the rotating shaft 301 is perpendicular to the moving direction of the support bar 201; the second grinding wheel 303 and the first grinding wheel 302 are connected by a metal spring 304; the end faces of the first grinding wheel 302 and the second grinding wheel 303 are parallel to the side walls of the support bar 201 perpendicular to the workbench 101, and the sliding direction of the second grinding wheel 303 is parallel to the central axis of the rotating shaft 301.

[0023] In this way, the driving mechanism controls the rotation of the shaft 301 during the movement of the support bar 201 on the workbench 101, and the rotation of the shaft 301 drives the two grinding wheels to rotate. The two grinding wheels are always in contact with the two side walls of the support bar 201 under the action of the metal spring 304, and this continuous contact will generate friction. On the one hand, this friction can clean the impurities on the two side walls of the support bar 201; on the other hand, this friction can increase the temperature of the two side walls of the support bar 201, which is beneficial to the subsequent pasting process; on the third hand, this friction can assist in the movement of the support bar 201, making the movement of the support bar 201 smoother.

[0024] Although the above structure can achieve the functions of heating, cleaning and auxiliary pushing of the support bar 201 with a rectangular cross-section, there are still some problems: for the support bar 201 with a rectangular cross-section, the widths of support bars 201 of different sizes (this width is the distance between the first grinding wheel 302 and the second grinding wheel 303 when the two grinding wheels clamp the support bar 201 therebetween) are all different. Therefore, when the support bar 201 is clamped by the two grinding wheels, the clamping force between the two grinding wheels will be affected by the elastic force of the metal spring 304 between the two. Specifically, when the width of the support bar 201 is narrow, the elongation of the metal spring 304 is short, and thus the elastic force of the metal spring 304 is small. This may cause the clamping force of the two grinding wheels to be weak, or even the metal spring 304 may not work, and the two grinding wheels therefore have no clamping effect; when the width of the support bar 201 is wide, the elongation of the metal spring 304 is long, and its elastic force is large. This elastic force will cause the clamping force of the two grinding wheels to be large under the action of the metal spring 304. If the two grinding wheels clamp the support bar 201 tightly under the action of the elastic force of the metal spring 304, it will affect the smooth movement of the support bar 201 on the workbench 101.

[0025] Therefore, in order to solve the above problem, in this embodiment, an adjustment mechanism for adjusting the expansion and contraction amount of the metal spring 304 is specially installed on the rotating shaft 301, which can conveniently adjust the expansion and contraction amount (elastic force) of the metal spring 304 between the two grinding wheels, so that when the support bars 201 of different widths within a certain size range are clamped between the two grinding wheels, the clamping force of the two grinding wheels on the support bar 201 under the action of the metal spring 304 is more appropriate, so that the metal spring 304 can achieve the clamping effect when achieving the clamping effect, and will not affect the movement of the support bar 201.

[0026] Specifically, refer to Figure 3 The adjustment mechanism includes a positive electrode 401 embedded in the first grinding wheel 302, a resistor bar 402 embedded in the rotating shaft 301, a negative electrode 403 embedded in the second grinding wheel 303, and an inner telescopic tube 404 and an outer telescopic tube 405 sleeved on the rotating shaft 301. The positive electrode 401 and the negative electrode 403 are symmetrically arranged about the central axis of the rotating shaft 301; the resistor bar 402 is a U-shaped structure, and the extension directions of the two straight segments of the resistor bar 402 are parallel to the central axis of the rotating shaft 301, and the two ends of the resistor bar 402 are both facing the first grinding wheel 302; the positive electrode 401 is electrically connected to the resistor bar 402; the negative electrode 403 is connected to a conductive bar 406, and the conductive bar 406 is slidably connected to the resistor bar 402. In order to facilitate the conductive bar 406 to slide on the rotating shaft 301, a slide groove 1101 is specially provided on the rotating shaft 301; the positive electrode 401 and the negative electrode 403 are both electrically connected to the metal spring 304. Therefore, the positive electrode 401, the resistor strip 402, the conductive strip 406, the negative electrode 403 and the spring form a complete series path, and electricity is passed through the series path during operation.

[0027] One end of the inner telescopic tube 404 and one end of the outer telescopic tube 405 are respectively sealed and connected to the first grinding wheel 302, and the other ends of the two are respectively sealed and connected to the second grinding wheel 303, and the inner telescopic tube 404 is located inside the outer telescopic tube 405; the metal spring 304 is located between the outer telescopic tube 405 and the inner telescopic tube 404; the space between the outer telescopic tube 405 and the inner telescopic tube 404 is filled with quick-heating liquid, and an expansion unit is provided between the outer telescopic tube 405 and the inner telescopic tube 404. In this way, the inner telescopic tube 404, the outer telescopic tube 405, the first grinding wheel 302, the second grinding wheel 303 and the rotating shaft 301 form a closed chamber.

[0028] Specifically, in this embodiment, the expansion unit includes a plurality of expansion rings 407 disposed on the inner wall of the outer telescopic tube 405 and abutting against each other. The expansion ring 407 close to the first grinding wheel 302 is connected to the first grinding wheel 302 , and the expansion ring 407 close to the second grinding wheel 303 is connected to the second grinding wheel 303 .

[0029] from Figure 3 From the perspective of Figure 3 The state is the clamping state of the support bar 201 with the narrowest width within a certain size range. At this time, the elastic force generated by the deformation of the metal spring 304 makes the clamping effect of the two grinding wheels on the support bar 201 within the normal clamping range. At this time, the resistance value of the series path composed of the positive electrode 401, the resistor bar 402, the conductive bar 406, the negative electrode 403 and the metal spring 304 is at a normal value, so the current flowing through the metal spring 304 is a normal value, the temperature of the metal spring 304 will not increase, and its elastic force will not be affected by the temperature. When this "clamp" clamps the support bar 201 with a wider width within a certain size range, the metal spring 304 is stretched at this time, and the second grinding wheel 303 moves to the right along the X-axis. When the second grinding wheel 303 moves to the right, the resistance value of the resistor bar 402 in the series path composed of the positive electrode 401, the resistor bar 402, the conductive bar 406, the negative electrode 403 and the metal spring 304 will decrease, because the effective length of the resistor bar 402 in this series path is reduced. According to Ohm's law, when the voltage value in the series circuit is constant, when the resistance decreases, the current in the circuit will increase. Since the spring here is a metal spring 304, the elastic force of the metal spring 304 is affected by temperature, and its elastic force will change with the change of temperature. Its elastic force is proportional to the degree of deformation. This phenomenon is called thermal expansion effect: when the metal spring 304 is subjected to high temperature, due to the enhancement of molecular thermal motion, the intermolecular distance of the metal spring 304 will increase, thereby causing the degree of deformation of the metal spring 304 to decrease, and the elastic force will also decrease accordingly; on the contrary, when the metal spring 304 is subjected to low temperature, the molecular distance of the metal spring 304 will decrease, the degree of deformation will increase, and the elastic force will also increase accordingly.

[0030] Therefore, when the current in the metal spring 304 increases, its own temperature will increase. On the one hand, the increase in the temperature of the metal spring 304 itself causes its own elastic force to decrease. This phenomenon will reduce the situation where the two grinding wheels clamp the support bar 201 tightly due to excessive elastic force, which affects the smooth movement of the support bar 201 on the workbench 101. The elastic force generated by the deformation of the metal spring 304 makes the clamping effect of the two grinding wheels on the support bar 201 within the normal clamping range. On the other hand, the heat generated by the increase in the temperature of the metal spring 304 itself will be transferred to the quick-heating liquid in the closed chamber formed by the inner telescopic tube 404, the outer telescopic tube 405, the first grinding wheel 302, the second grinding wheel 303 and the rotating shaft 301, and the temperature of the quick-heating liquid will rise rapidly. After the quick-heating liquid is heated, its volume expands, which will overcome the expansion and contraction of a part of the telescopic tube. The temperature of the quick-heating liquid will be transmitted to each expansion ring 407. After being heated, each expansion ring 407 will expand along the radial direction of the rotating shaft 301 on the one hand, and along the axial direction of the rotating shaft 301 on the other hand. Refer to Figure 3 The expansion force generated by the expansion along the axial direction of the rotating shaft 301 will act on the second grinding wheel 303, causing the second grinding wheel 303 to tend to move to the right. This phenomenon will also offset a portion of the leftward pulling force of the metal spring 304, causing the pulling force of the metal spring 304 on the second grinding wheel 303 to become smaller, and further the elastic force generated by the deformation of the metal spring 304 makes the clamping effect of the two grinding wheels on the support bar 201 within the normal clamping range, so that the two grinding wheels can clean and heat up the two side walls of the support bar 201 without affecting the clamping force generated by this "clamp" and affecting the smooth movement of the support bar 201 on the workbench 101.

[0031] There are many options for the above-mentioned fast-heating liquids, such as water (water can expand quickly after being heated and can cool naturally quickly), liquid ammonia (a common low-temperature liquid that will expand and contract when the temperature rises), alcohol (alcohol will expand when the temperature rises and contract when the temperature drops) and some heat transfer oils.

[0032] The expansion ring 407 may be made of a material that expands when heated in water, such as polyethylene, polypropylene, silicone rubber, and chloroprene rubber.

[0033] In order to further improve the cleanliness of the two side walls of the support bar 201, the cleaning mechanism also includes a dust blowing mechanism arranged on the workbench 101. There are two groups of dust blowing mechanisms, and the two groups of dust blowing mechanisms are respectively located on both sides of the support bar 201. The driving ends of the two groups of dust blowing mechanisms are transmission connected to the rotating shaft 301, and the wind blown out through the air outlets of the two groups of dust blowing mechanisms is blown onto the two side walls perpendicular to the support bar 201 and the workbench 101.

[0034] Reference Figure 1 or Figure 2The dust blowing mechanism includes a push rod 501, a piston 502 and an air jet 503 connected in sequence and arranged on the workbench 101. The air blown out of the air outlet of the air jet 503 blows toward the side wall of the support bar 201 perpendicular to the workbench 101. The rotating shaft 301 is a crankshaft. Two connecting rod journals 601 are arranged at intervals on the rotating shaft 301. One end of the push rod 501 away from the piston 502 is rotatably connected to the corresponding connecting rod journal 601. In this way, during the self-rotation of the rotating shaft 301 with a crankshaft structure, the two pistons 502 repeatedly push the air in the two air jets 503 under the action of the two push rods 501, so that the air in the two air jets 503 is blown toward the two side walls of the support bar 201 at a certain speed. This wind can further remove dust from the two side walls of the support bar 201, further improving the cleanliness of the two side walls of the support bar 201.

[0035] Reference Figure 1 or Figure 2 In this embodiment, the Z-axis limiting mechanism includes at least one limiting cylinder 701, which is located above the travel direction of the support bar 201, and the two ends of the limiting cylinder 701 are connected to the workbench 101 through brackets. The two ends of the limiting cylinder 701 can be rotatably connected to the two brackets respectively, so that when the support bar 201 passes through the area below the limiting cylinder 701, if the support bar 201 contacts the limiting cylinder 701, the sliding contact between the support bar 201 and the limiting cylinder 701 changes to rolling contact, and this rolling contact is line contact here, and this line contact can reduce the friction between the two, so as to reduce the resistance of the support bar 201 to move on the workbench 101.

[0036] Reference Figure 1 or Figure 2 In this embodiment, the gluing mechanism includes two glue strip release plates 801 and two first guide wheels 802, which are both rotatably connected to the workbench 101. The two glue strip release plates 801 and the two first guide wheels 802 are symmetrically arranged on both sides of the support bar 201; the double-sided glue strip 1001 on any glue strip release plate 801 can be covered on one side of the support bar 201 after bypassing the corresponding first guide wheel 802.

[0037] Reference Figure 1 or Figure 2 , one of the first guide wheels 802 is connected to the workbench 101 through the first elastic telescopic rod 803, the first guide wheel 802 is rotatably connected to the first elastic telescopic rod 803, and the telescopic direction of the first elastic telescopic rod 803 is not parallel to the moving direction of the support bar 201. This design can ensure that the double-sided adhesive strip 1001 and the support bar 201 are always in a bonding state at the starting point of the bonding, ensuring the smooth progress of the bonding process. The first elastic telescopic rod 803 adopts a telescopic structure commonly used in the prior art, which will not be described in detail here.

[0038] When the support bar 201 cleaned by the cleaning mechanism is about to enter the area between the two first guide wheels 802, the free ends of the two double-sided adhesive strips 1001 are respectively passed around the corresponding first guide wheels 802 and then pasted on the side walls of the corresponding support bar 201. Figure 2 From the perspective of the support bar 201, after the free ends of the two double-sided adhesive strips 1001 are respectively attached to the two side walls of the support bar 201, the support bar 201 continues to move downward. During the downward movement of the support bar 201, the adhesive section of the double-sided adhesive strips 1001 and the support bar 201 will not be separated due to the adhesive force, and the two adhesive strip release plates 801 rotate synchronously under the action of this adhesive force. As the support bar 201 continues to move downward, the two double-sided adhesive strips 1001 continue to be attached to the two side walls of the support bar 201 under the action of the two first guide wheels 802 and the first elastic telescopic rod 803.

[0039] In this embodiment, the X-axis limiting mechanism includes two second guide wheels 901 rotatably connected to the workbench 101 , and the two second guide wheels 901 are symmetrically arranged on both sides of the support bar 201 .

[0040] Reference Figure 1 or Figure 2 In order to improve the limiting accuracy of the X-axis limiting mechanism, one of the second guide wheels 901 is connected to the workbench 101 through a second elastic telescopic rod 902, and the second guide wheel 901 is rotationally connected to the second elastic telescopic rod 902, and the telescopic direction of the second elastic telescopic rod 902 is not parallel to the moving direction of the support strip 201. In this way, on the first hand, when the support strip 201 passes between the two second guide wheels 901 after the pasting process is completed, under the action of the elastic force of the second elastic telescopic rod 902, the two second guide wheels 901 are respectively in contact with the sides of the two double-sided adhesive strips 1001, so that the support strip 201 cannot move back and forth in the X-axis direction, so that it moves along the Y-axis direction; on the second hand, the elastic force of the second elastic telescopic rod 902 will act on the side wall of one of the double-sided adhesive strips 1001, and this pressure makes the double-sided adhesive strip 1001 fully contact with the support strip 201, thereby enhancing the bonding force between the two. Among them, the second elastic telescopic rod 902 also adopts a telescopic structure commonly used in the prior art, which will not be described in detail here.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
