Description

TECHNICAL FIELD

[0001] The present application relates to the field of keyboard conductive film and keyboard silica gel particle production, in particular to a keyboard silica gel particle end face glue printing method.

[0002] The present application also relates to a keyboard silica gel particle end face glue printing machine. BACKGROUND

[0003] At present, most of the silica gel keyboard needs to be pasted and attached with glue before assembly and production, that is, the keyboard conductive film and the keyboard silica gel particle are pasted and attached with glue. The pasting method is to first print glue on the keyboard conductive film with a silk screen printing machine, and then paste and attach the keyboard conductive film printed with glue with the keyboard silica gel particle placed on the template. This method has the following disadvantages:

[0004] Disadvantage one, when silk screen printing is performed on the keyboard conductive film, the keyboard conductive film needs to be first moved and placed on the silk screen printing base of the silk screen printing machine and positioned, then the silk screen printing screen is lowered to be close to the keyboard conductive film, then the doctor blade scrapes glue on the silk screen printing screen, then the silk screen printing screen is raised to be away from the keyboard conductive film, and then the keyboard conductive film printed with glue is moved and sent to the template full of keyboard silica gel particles. The above operation process takes a long time, and it usually takes 5 to 8 seconds to complete one piece in actual production, which means that 400 to 650 pieces can be silk screen printed per hour, the speed of small pieces is faster, up to 700 pieces per hour, the speed of large pieces is slower, more than 300 pieces per hour, and the speed of extra-large pieces is even slower, more than 200 pieces per hour. The above production efficiency is low and cannot meet the efficiency requirements of actual production.

[0005] Disadvantage two, silk screen printing is performed on the keyboard conductive film, and basically one piece of film is silk screen printed at a time in actual production, so the production efficiency cannot be improved. Some factories have tried to silk screen print two pieces of film at a time, but it is found in actual operation that the feeding and taking of two pieces of film takes a lot of time and cannot improve the efficiency, and it is not easy to accurately position two pieces of film on the silk screen printing base at the same time. If three, four, five or more pieces of film are silk screen printed at a time, more time is occupied, and it is very difficult to position multiple pieces of film on the silk screen printing base at the same time.

[0006] Disadvantage three, due to the error of silk screen printing, in order to compensate for the error, the factory currently makes the area of the silk screen printing glue larger than the area of the end face of the keyboard silica gel particle, which causes waste of glue and increases the cost of glue materials.

[0007] The fourth disadvantage is that the end face of the keyboard silica gel particle has an exhaust gap, and the exhaust gap is not glued. When the keyboard silica gel particle is pasted with the keyboard conductive film, the direction of the exhaust gap is random. Therefore, the factory currently prints glue on the corresponding position of the keyboard conductive film, including the exhaust gap part, which causes waste of glue and increases the cost of glue material.

[0008] The fifth disadvantage is that the keyboard conductive film is usually composed of three sub-films. In the first case, the three sub-films are completely pasted together to form an integrated keyboard conductive film. In the second case, the three sub-films are not pasted together to form a non-integrated keyboard conductive film, but are connected by several fusion points. For the non-integrated keyboard conductive film, only the lowermost sub-film can be vacuumed on the silk screen base, and the uppermost sub-film is adhered to the silk screen plate by the glue, so that automatic silk printing cannot be realized. Moreover, for the non-integrated keyboard conductive film, automatic feeding and automatic taking cannot be realized by vacuum suction, so that full-automatic production cannot be realized. SUMMARY

[0009] The technical problem to be solved by the present application is to provide a keyboard silica gel particle end face glue printing method which can realize high efficiency, automation and saving of glue material cost.

[0010] Another technical problem to be solved by the present application is to provide a keyboard silica gel particle end face glue printing machine which can realize high efficiency, automation and saving of glue material cost.

[0011] The above technical problem is solved by the keyboard silica gel particle end face glue printing method as follows:

[0012] Step 1, a template is provided, and template positioning holes corresponding to the positions of the keyboard silica gel particles are provided on the template;

[0013] Step 2, the template positioning holes on the template are filled with keyboard silica gel particles;

[0014] Step 3, glue is applied to the glue applying surface of the glue applying part;

[0015] Step 4, the template filled with keyboard silica gel particles or the glue applying part is moved, so that the end face of the keyboard silica gel particle in the template positioning hole on the template is opposite to the glue applying surface of the glue applying part;

[0016] Step 5, moving the template with the keyboard silica gel particles or moving the glue applying part, so that the two are close to each other, the end surface of the keyboard silica gel particles in the template positioning hole on the template is in contact with the glue applying surface on the glue applying part, so that the glue on the glue applying surface is printed on the end surface of the keyboard silica gel particles.

[0017] Step 6, separating the template from the glue applying part, the keyboard silica gel particles are left in the template positioning hole on the template, so that the glue is printed on the end surface of the keyboard silica gel particles.

[0018] Step 7, sticking the keyboard silica gel particles with the glue printed on the end surface to the keyboard conductive film.

[0019] Preferably, the end surface of the keyboard silica gel particles in the template positioning hole on the template in step 4 is upward, and the glue applying surface on the glue applying part is downward, and the two are opposite to each other. Alternatively, preferably the end surface of the keyboard silica gel particles in the template positioning hole on the template in step 4 is downward, and the glue applying surface on the glue applying part is upward, and the two are opposite to each other.

[0020] Preferably, the back of the template in step 5 is connected with an air cavity assembly, the template positioning hole on the template has a through hole connecting the air cavity assembly, when the end surface of the keyboard silica gel particles on the template is in contact with the glue applying surface on the glue applying part, the air cavity assembly is connected with compressed gas to blow the keyboard silica gel particles in the template positioning hole on the template, so that the end surface of the keyboard silica gel particles is in more reliable contact with the glue applying surface on the glue applying part; after a delay, the compressed gas is turned off.

[0021] Preferably, the back of the template in step 6 is connected with an air cavity assembly, the template positioning hole on the template has a through hole connecting the air cavity assembly, when the template is separated from the glue applying part, the keyboard silica gel particles are left in the template positioning hole on the template.

[0022] The method has the following advantages: (1) the end surface of the keyboard silica gel particle in the template positioning hole of the template contacts the glue applying surface of the glue applying member, and then separates, so that glue is adhered to the end surface of the keyboard silica gel particle, the operation time is very short, and thus the glue adhering efficiency is significantly improved. The glue adhering efficiency of the method is 2000 groups per hour (one group refers to the silica gel particles to be adhered to one conductive film piece of a keyboard, and corresponds to all keys of one keyboard), which is much higher than the silk printing efficiency of 400 to 650 pieces per hour. (2) Multiple groups can be adhered at the same time, and the glue adhering efficiency is further improved. (3) Since the glue is directly adhered to the end surface of the keyboard silica gel particle, the exhaust gap of the end surface of the keyboard silica gel particle is not adhered to the glue, and the silk printing area does not need to be increased as in the current silk printing, so that the waste of glue is avoided, and the glue material cost is reduced. (4) Since the glue is directly adhered to the end surface of the keyboard silica gel particle instead of being silk printed on the conductive film piece of the keyboard, the non-integrated conductive film piece of the keyboard cannot be sucked by vacuum, so that the full-automatic glue adhering is facilitated, and labor is saved.

[0023] The above problems are solved by the keyboard silica gel particle end surface glue adhering machine, which comprises a frame, a glue applying mechanism, a template mechanism and a glue uniformizing mechanism arranged on the frame. The glue applying mechanism comprises a glue applying member, and the glue applying member has a glue applying surface. The template mechanism is provided with a template, and the template is provided with template positioning holes corresponding to the keys of the keyboard. The template positioning holes are used for placing and positioning the keyboard silica gel particles. The glue uniformizing mechanism is used for applying a uniform thin layer of glue on the glue applying surface. The glue applying surface contacts the end surface of the keyboard silica gel particle and then separates, so that the thin layer of glue on the glue applying surface is adhered to the end surface of the keyboard silica gel particle.

[0024] Preferably, the glue applying mechanism is arranged above the template mechanism. Alternatively, preferably, the glue applying mechanism is arranged below the template mechanism.

[0025] Preferably, the gluing mechanism is an A conveying flat-belt gluing mechanism, which comprises an A conveying frame arranged on an A rack, an A driving shaft assembly rotatably connected with the A conveying frame, an A conveying belt driving unit connected with the A driving shaft assembly, an A driven shaft assembly rotatably connected with the A conveying frame, and an A conveying flat belt arranged between the A driving shaft assembly and the A driven shaft assembly; the A conveying flat belt is an A gluing element. An A glue uniformizing mechanism is arranged above the A conveying flat-belt gluing mechanism, and preferably the A glue uniformizing mechanism is an A glue scraping mechanism. Glue is placed on the A conveying flat belt, and then the A conveying belt driving unit drives the A conveying flat belt to move, so that the glue on the A conveying flat belt also moves, and then the A glue scraping mechanism is used to leave a thin layer of glue on the A conveying flat belt.

[0026] Preferably, an A ethylene cavity assembly is further arranged between the A driving shaft assembly and the A driven shaft assembly, and the A ethylene cavity assembly is surrounded by the A conveying flat belt; an A1 hole is arranged on the A ethylene cavity assembly; and an A2 hole is arranged on the A ethylene cavity assembly. The A1 hole is used to connect a vacuum, and the vacuum flows to the A2 hole, so that the conveying flat belt is sucked by the vacuum on the A2 hole.

[0027] Preferably, the gluing mechanism is a B overturning gluing mechanism, which comprises a B gluing element and a B overturning driving unit; the B gluing element is a B overturning flat plate, and an outer surface of the B overturning flat plate is a B overturning flat plate gluing surface; and the B overturning driving unit drives the B overturning flat plate to rotate between 0 degrees and 180 degrees.

[0028] Preferably, the gluing mechanism is a C swinging gluing mechanism, which comprises a C gluing element and a C swinging driving unit; the C gluing element is a C swinging flat plate, and an outer surface of the C swinging flat plate is a C swinging flat plate gluing surface; and the C swinging driving unit drives the C swinging flat plate to swing between 0 degrees and 180 degrees.

[0029] Preferably, the gluing mechanism is a D cylindrical gluing mechanism, which comprises a D cylinder, a D flat plate, and a D glue container; a lower surface of the D flat plate is a D flat plate gluing surface; glue is placed in the D glue container, and the glue is adhered to the D flat plate gluing surface by rotation of the D cylinder.

[0030] Preferably, the template mechanism adopts an E template mechanism, and the glue applying mechanism adopts an E flat plate glue applying mechanism; the E template mechanism is arranged above the E flat plate glue applying mechanism; the E template mechanism comprises an E shell cavity assembly, and an E turnover driving unit; an E air hole is formed on the E shell cavity assembly; a template is arranged on the E shell cavity assembly; keyboard silica gel particles are placed in template positioning holes on the template; the E turnover driving unit drives the E shell cavity assembly and the template arranged thereon to turn over between 0 degree and 180 degree positions; the E air hole is used to connect a vacuum to suck the keyboard silica gel particles in the template positioning holes on the template to prevent the keyboard silica gel particles from falling off in the above turnover process.

[0031] Preferably, the glue applying mechanism adopts a glue scraping mechanism to leave a thin layer of glue on the glue applying surface. Preferably, the template mechanism further comprises a shell cavity assembly, and an air hole is formed on the shell cavity assembly. A template is arranged on the template mechanism, and template positioning holes corresponding to positions of keys of a keyboard are formed on the template; the template positioning holes are filled with keyboard silica gel particles.

[0032] The template mechanism or the glue applying mechanism is driven to make end surfaces of the keyboard silica gel particles in the template positioning holes on the template on the template mechanism contact the thin layer of glue on the glue applying surface on the glue applying mechanism, and then the air hole on the shell cavity assembly is connected to a vacuum to suck the silica gel particles in the template positioning holes. Then the template mechanism or the glue applying mechanism is driven again to separate the keyboard silica gel particles on the template mechanism from the glue applying surface, and then the vacuum of the air hole is disconnected, so that the end surfaces of the keyboard silica gel particles are printed with glue.

[0033] Finally, the keyboard silica gel particles on which glue has been printed are sent to a next process together with the template to be attached to a conductive film of a keyboard.

[0034] The keyboard silicone particle end face glue printing machine has the following advantages: (1) the end face of the keyboard silicone particle in the template positioning hole of the template contacts the glue coating surface of the glue coating member and then separates, so that glue is printed on the end face of the keyboard silicone particle, the operation time is very short, and therefore the glue printing efficiency is significantly improved. The glue printing efficiency of the keyboard end face glue printing machine is 2000 groups per hour (one group refers to the silicone particles to be adhered to one piece of keyboard conductive film, and corresponds to all the keys of one keyboard), which is much higher than the silk printing efficiency of 400 to 650 pieces per hour at present. (2) Multiple groups can be printed at the same time, and the glue printing efficiency is further improved. (3) Since the glue is directly printed on the end face of the keyboard silicone particle, the exhaust gap of the end face of the keyboard silicone particle does not adhere to the glue, and the silk printing area does not need to be increased as in the current silk printing, so that the waste of glue is avoided, and the cost of glue material is reduced. (4) Since the glue is directly printed on the end face of the keyboard silicone particle instead of being silk printed on the keyboard conductive film, the non-integrated keyboard conductive film cannot be vacuumed, and therefore the full-automatic glue printing is facilitated, and the labor is saved.

[0102] Embodiment one: as Figures 1 to 22 , the keyboard silicone particle end face gluing machine of the present application using A conveying flat belt gluing mechanism a100 comprises A rack a1, A conveying flat belt gluing mechanism a100, A glue uniformizing mechanism a2, A template mechanism a200 are arranged on the A rack a1, the A conveying flat belt gluing mechanism a100 comprises A gluing part a3, preferably the A glue uniformizing mechanism a2 adopts A glue scraping mechanism a320, the A glue scraping mechanism a320 is erected on the upper surface of the A conveying flat belt gluing mechanism a100, and the A template mechanism a200 is arranged below the A conveying flat belt gluing mechanism a100.

[0103] The A conveying flat belt gluing mechanism a100 comprises A conveying frame a133 arranged on the A rack a1, A driving shaft assembly a131 rotationally connected with the A conveying frame a133, A conveying belt driving unit a134 connected with the A driving shaft assembly a131, A driven shaft assembly a132 rotationally connected with the A conveying frame a133, and A conveying flat belt a121 arranged between the A driving shaft assembly a131 and the A driven shaft assembly a132; the A gluing part a3 is the A conveying flat belt a121; preferably the A conveying belt driving unit a134 adopts A conveying belt motor a135. When the A conveying belt motor a135 rotates, it drives the A conveying flat belt a121 to move.

[0104] An A ethylene cavity assembly a140 is further arranged between the A driving shaft assembly a131 and the A driven shaft assembly a132, which is surrounded by the A conveying flat belt a121; an A1 hole a141 is arranged on the A ethylene cavity assembly a140; an A2 hole a142 is arranged on the A ethylene cavity assembly a140.

[0105] A glue spreading mechanism a2 is also provided above the conveyor belt a121. Preferably, the glue spreading mechanism a2 utilizes a glue scraping mechanism a320. The glue scraping mechanism a320 includes a scraper holder a330 equipped with a scraper a331. Leakage prevention members a332 are also provided at both ends of the scraper a331. The A-squeegee mechanism a320 also includes an A1 adjustment mechanism a310, which comprises an A1 fixing plate a311, an A1 slider a312, an A1 guide rail a313, and an A1 screw unit a314. The A1 fixing plate a311 is fixed to the A-frame a1, the A1 slider a312 is fixed to the A1 fixing plate a311, and the A1 guide rail a313 is slidably coupled to the A1 slider a312. One end of the A1 guide rail a313 is fixedly connected to the A-squeegee frame a330. The gap between the A-squeegee a331 and the outer surface of the upper section of the A-conveyor flat belt a121 can be adjusted by rotating the A1 screw unit a314.

[0106] like Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 On the outer surface of the upper section of the A conveying flat belt a121, located on the left side of the A scraper a331, is the A glue placement area a123 for placing glue. When the A conveying belt motor a135 drives the A conveying flat belt a121 to move, the upper section of the A conveying flat belt a121 is pressed Figure 8 Moving from left to right, due to the obstruction of scraper a331, only a portion of the glue in glue placement area a123 passes through the gap between scraper a331 and the outer surface of the upper section of conveyor belt a121, forming a thin layer of glue on the outer surface of the upper section of conveyor belt a121, to the right of scraper a331. The remaining glue is blocked by scraper a331 in glue placement area a123. The leak-proof member a332 prevents glue from leaking from both ends of scraper a331. The thickness of this thin layer of glue can be adjusted by rotating the A1 screw unit a314 to adjust the gap between scraper a331 and the outer surface of the upper section of conveyor belt a121. When the above-mentioned A conveyor belt motor a135 drives the A conveyor belt a121 to continue to move in the original direction, the thin layer of glue follows the A conveyor belt a121 to move to the Figure 10 、 Figure 11 As shown in the A flat belt gluing area a124, at this time, the outer surface of the lower section of the A conveying flat belt a121 of the A flat belt gluing area a124 is the A flat belt gluing surface a122.

Fixed connection; the A template mechanism a200 also includes a template 011, which is provided with a template positioning hole 012, and the template positioning hole 012 on the template 011 is filled with keyboard silicone particles 021, and the template 011 is placed on the A-type cavity component a220; the A template lifting cylinder a236 drives the A-type cavity component a220 and the template 011 placed thereon to rise or fall, so that the template 011 and the keyboard silicone particles 021 in the positioning hole thereof are close to or away from the A flat belt coating surface a122.

[0108] The working process is as follows:

[0109] First, put glue in the glue placement area a123, and rotate the A1 screw unit a314 to adjust the gap between the A scraper a331 and the outer surface of the upper section of the A conveyor belt a121; then the A conveyor belt motor a135 drives the A conveyor belt a121 to press Figure 8 From the perspective, the upper section of the A conveyor belt a121 moves from left to right, and a part of the glue on the A glue placement area a123 passes through the gap between the A scraper a331 and the outer surface of the upper section of the A conveyor belt a121, forming a thin layer of glue on the right side of the A scraper a331, while the other part of the glue is blocked by the A scraper a331 in the A glue placement area a123, and at the same time, the A leak-proof part a332 can prevent the glue from leaking from the two ends of the A scraper a331; the A conveyor belt a121 continues to move in the direction described above, and the thin layer of glue follows the A conveyor belt a121 to move to Figure 10 、 Figure 11The A flat belt glue coating area a124 is shown. At this time, the outer surface of the lower section of the A conveying flat belt a121 of the A flat belt glue coating area a124 is the A flat belt glue coating surface a122. At this point, the A conveying belt motor a135 is paused, and the A conveying flat belt a121 is also paused.

[0110] Next, the A mold plate lifting cylinder a236 drives the A cavity assembly a220 and the mold plate 011 placed thereon to rise, so that the end face of the keyboard silica gel particle 021 placed in the mold plate positioning hole 012 is close to the A flat belt glue coating surface a122. At this time, the end face of the keyboard silica gel particle 021 is glued.

[0111] Preferably, next, the A air hole a221 on the A cavity assembly a220 is connected to compressed gas, and the keyboard silica gel particle 021 in the mold plate positioning hole 012 is blown, so that the end face of the keyboard silica gel particle 021 is more reliably in contact with the A flat belt glue coating surface a122.

[0112] Next, the A air hole a221 on the A cavity assembly a220 is closed to compressed gas and switched to vacuum, so that the keyboard silica gel particle 021 is sucked tightly in the mold plate positioning hole 012 and the mold plate 011 is sucked tightly on the A cavity assembly a220.

[0113] Preferably, next, the A1 hole a141 on the A cavity assembly a140 is connected to vacuum, and the vacuum passes through the A2 hole a142 to suck the lower section of the A conveying flat belt a121 firmly.

[0114] Next, the A mold plate lifting cylinder a236 drives the A cavity assembly a220 and the mold plate 011 sucked thereon to descend, and the keyboard silica gel particle 021 sucked tightly in the mold plate positioning hole 012 also descends together and separates from the A flat belt glue coating surface a122. During this separation process, since the lower section of the A conveying flat belt a121 has been sucked firmly by the vacuum in the A cavity assembly a140, the lower section of the A conveying flat belt a121 will not be deformed by the adhesive force.

[0115] After the above separation is completed, next, the A cavity assembly a220 is disconnected from the vacuum, and the A cavity assembly a140 is also disconnected from the vacuum.

[0116] In this way, the end face of the keyboard silica gel particle 021 in the mold plate positioning hole 012 is glued.

[0117] Next, the A conveying belt motor a135 is rotated again to drive the A conveying flat belt a121 to move forward by one step, and the end face of the keyboard silica gel particle 021 in the mold plate positioning hole 012 is close to the A flat belt glue coating surface a122 again. Figure 8Viewing angle, the upper section of the A conveying flat belt a121 moves from left to right; at the same time, the mold plate 011 and the keyboard silica gel particles 021 in the positioning hole move to the next process, and another mold plate 011 and the keyboard silica gel particles 021 in the positioning hole move to the top of the A cavity assembly a220, starting the next glue printing cycle.

[0128] As Figure 24 , Figure 25 , Figure 32 , Figure 33 , Figure 34 , Figure 35 , the B template mechanism b200 comprises a B left cavity assembly b220, and a B air hole b221 is formed in the B left cavity assembly b220; the B template mechanism b200 is connected with a B template lifting assembly b230, the B template lifting assembly b230 comprises a B1 fixing piece b231, a B2 fixing piece b234, a B template lifting sliding block b232, a B template lifting guide rail b233, and a B template lifting driving unit b235, preferably the B template lifting driving unit b235 adopts a B template lifting air cylinder b236; the B template lifting sliding block b232 is connected with the B template mechanism b200; the B template lifting sliding block b232 is in sliding connection with the B template lifting guide rail b233, the B template lifting guide rail b233 is fixedly connected with the B1 fixing piece b231, and the B1 fixing piece b231 is fixedly connected with the B2 fixing piece b234; the cylinder body of the B template lifting air cylinder b236 is fixedly connected with the B2 fixing piece b234, and the piston shaft of the B template lifting air cylinder b236 is connected with the B template mechanism b200; the B template mechanism b200 further comprises a template 011, a template positioning hole 012 is formed in the template 011, the template positioning hole 012 on the template 011 is filled with keyboard silica gel particles 021, and the template 011 is placed on the B left cavity assembly b220. The B template lifting air cylinder b236 drives the B template mechanism b200 and the B left cavity assembly b220 thereon to ascend or descend.

[0129] The working process and working principle are as follows: ​

[0130] First, adjust the B flipping and gluing mechanism b100 so that the B flipping plate b121 is on top and the gluing surface b122 of the B flipping plate is facing upward; then adjust the B scraping mechanism b310 so that when the B scraper holder b316 drops to the bottom, there is a suitable gap between the B scraper b317 and the gluing surface b122 of the B flipping plate; then the left and right B side wing cylinders b922 respectively drive the left and right B side wing plates b911 to approach the B flipping plate b121.

[0131] Next, the B-squeegee cylinder b325 drives the B-squeegee mechanism b310 to move to the left B-wing mechanism b900 (or first to the right B-wing mechanism b900; the principle is the same). The left B-squeegee lift cylinder b315 then drives the left B-squeegee holder b316 down, bringing the left B-squeegee b317 closer to the left B-wing plate b911. Simultaneously, the right B-squeegee lift cylinder b315 drives the right B-squeegee holder b316 up, moving the right B-squeegee b317 away from the left B-wing plate b911. Glue is then applied to the left B-wing plate b911, between the left and right B-squeegees b317.

[0132] Then the B scraper cylinder b325 drives the B scraper mechanism b310 to move to the right, pass through the B flip flat plate glue coating surface b122, and reach the top of the right B side wing flat plate b911. In the above process, due to the small gap between the left B scraper b317 and the B flip flat plate glue coating surface b122, a thin layer of glue will be left on the B flip flat plate glue coating surface b122, and the excess glue will be brought to the right B side wing flat plate b911 by the left B scraper b317.

[0133] Then, the left and right B wing cylinders b922 respectively drive the left and right B wing plates b911 to separate from the B flip plate b121.

[0134] Then, the B flip motor b132 drives the B flip gluing mechanism b100 to flip 180 degrees, so that the B flip flat plate gluing surface b122 faces downward. At this time, the B flip flat plate gluing surface b122 is opposite to the keyboard silicone particles 021 in the template positioning hole 012 on the template 011 on the B template mechanism b200.

[0135] Then, the B template lifting cylinder b236 drives the B template mechanism b200 and the template 011 placed thereon to rise, and when rising to the end, the end face of the keyboard silica gel particle 021 in the template positioning hole 012 of the template 011 contacts the B overturning flat plate glue applying surface b122. Then, preferably, the B air hole b221 on the B A cavity assembly b220 connects compressed gas to blow up the keyboard silica gel particle 021 in the template positioning hole 012 on the template 011 placed thereon, so that the end face of the keyboard silica gel particle 021 is in more reliable contact with the B overturning flat plate glue applying surface b122, and after a delay, the B air hole b221 is closed to disconnect the compressed gas.

[0136] Then, the B air hole b221 on the B A cavity assembly b220 switches to connect vacuum to suck the keyboard silica gel particle 021 in the template positioning hole 012 on the template 011.

[0137] Then, the B template lifting cylinder b236 drives the B template mechanism b200 and the template 011 placed thereon to descend, so that the keyboard silica gel particle 021 in the template positioning hole 012 on the template 011 is separated from the B overturning flat plate glue applying surface b122, so that the end face of the keyboard silica gel particle 021 is glued (equivalent to printing glue); then, the B air hole b221 is closed to disconnect the vacuum. When the template 011 descends to the end, the template 011 and the keyboard silica gel particle 021 placed thereon which has been glued are transferred to the next process.

[0138] Then, another template 011 on which the keyboard silica gel particle 021 is placed is transferred to the B A cavity assembly b220.

[0139] Then, the B overturning motor b132 drives the B overturning glue applying mechanism b100 to overturn 180 degrees, so that the B overturning flat plate glue applying surface b122 faces upward. Then, the left and right B side wing air cylinders b922 drive the left and right B side wing flat plates b911 to approach the B overturning flat plate b121.

[0140] Then, the left B scraper lifting cylinder b315 drives the left B scraper frame b316 to rise so that the left B scraper b317 is away from the right B side wing flat plate b911; at the same time, the right B scraper lifting cylinder b315 drives the right B scraper frame b316 to descend so that the right B scraper b317 approaches the right B side wing flat plate b911.

[0141] Then, the B glue scraping cylinder b325 drives the B glue scraping mechanism b310 to move left to scrape glue, so that a thin layer of glue is left on the B overturning flat plate glue applying surface b122. Then, the above actions are repeated to work in a cycle.

[0142] It should be noted that the B flip plate b121 can be one or two symmetric, so the B flip plate glue surface b122 can be one or two, the principle of action is the same as above.

[0143] It should be noted that the structure of the above embodiment two, if the B flip glue mechanism b100 and the mutual position of the B template mechanism b200 is transformed, that is, the B template mechanism b200 is turned over 180 degrees, and is arranged on the upper surface of the B flip glue mechanism b100, belongs to equivalent replacement, belongs to the protection scope of the invention patent.

[0144] It should be noted that the structure of the above embodiment two, if the B scraping mechanism b310 is changed to a silk printing mechanism or other mechanism that can coat a thin layer of glue on the B flip plate glue surface b122, all belong to equivalent replacement, belong to the protection scope of the invention patent.

Then, adjust the two groups of C glue scraping mechanisms c310, so that when the C scraper holder c316 is lowered to the lowest position, the C scraper c317 and the C swing rotating plate gluing surface c122 have a suitable gap.

[0155] Then, the left C scraper lifting air cylinder c315 drives the left C scraper holder c316 to descend, so that the left C scraper c317 approaches the left C side wing plate c911, while the right C scraper lifting air cylinder c315 drives the right C scraper holder c316 to ascend, so that the right C scraper c317 moves away from the left C side wing plate c911. Then, glue is placed on the left C side wing plate c911 between the left C scraper c317 and the right C scraper c317.

[0156] Then, the C glue scraping cylinder c325 drives the C glue scraping mechanism c310 to move rightward, pass the C swing plate glue applying surface c122, and reach the upper surface of the right C side wing plate c911. During the above process, a thin layer of glue is left on the C swing plate glue applying surface c122 due to the small gap between the left C scraper c317 and the C swing plate glue applying surface c122, and the excess glue is taken away by the left C scraper c317 to the right C side wing plate c911.

[0157] Next, the left and right C side wing cylinders c922 respectively drive the left and right C side wing plates c911 to separate from the C swing plate c121.

[0158] Next, the C swing motor c132 drives the C swing arm c133 and the C swing plate c121 fixed thereon to swing from 0 degree to 180 degree, so that the C swing plate glue applying surface c122 faces downward. At this time, the C swing plate glue applying surface c122 is opposite to the keyboard silica gel particles 021 in the template positioning hole 012 on the template 011 on the C template mechanism c200.

[0159] Next, the C template lifting cylinder c236 drives the C template mechanism c200 and the template 011 placed thereon to rise. When the rising reaches the end, the end surface of the keyboard silica gel particles 021 in the template positioning hole 012 of the template 011 contacts the C swing plate glue applying surface c122. Next, preferably, the C air hole c221 on the C template cavity assembly c220 is connected to compressed gas to blow up the keyboard silica gel particles 021 in the template positioning hole 012 on the template 011 placed thereon, so that the end surface of the keyboard silica gel particles 021 more reliably contacts the C swing plate glue applying surface c122. After a delay, the C air hole c221 is closed to disconnect the compressed gas.

[0160] Next, the C air hole c221 on the C template cavity assembly c220 is switched to connect to vacuum to suck the keyboard silica gel particles 021 in the template positioning hole 012 on the template 011.

[0161] Next, the C template lifting cylinder c236 drives the C template mechanism c200 and the template 011 placed thereon to descend, so that the keyboard silica gel particles 021 in the template positioning hole 012 on the template 011 separate from the C swing plate glue applying surface c122. In this way, the end surface of the keyboard silica gel particles 021 is glued (equivalent to printed with glue). Then, the C air hole c221 is closed to disconnect the vacuum. When the template 011 descends to the end, the template 011 and the keyboard silica gel particles 021 with glue on which are placed are transferred to the next process.

[0162] Then, another template 011 with keyboard silica gel particles 021 is moved to the C cavity assembly c220.

[0163] Then, the C swing motor c132 drives the C swing arm c133 and the C swing plate c121 fixed thereon to swing from 180 degrees to 0 degrees, so that the C swing plate gluing surface c122 faces upward. Then, the left and right C side wing cylinders c922 drive the left and right C side wing plates c911 to approach the C swing plate c121.

[0164] Then, the left C scraper lifting cylinder c315 drives the left C scraper frame c316 to rise, so that the left C scraper c317 moves away from the right C side wing plate c911; at the same time, the right C scraper lifting cylinder c315 drives the right C scraper frame c316 to descend, so that the right C scraper c317 approaches the right C side wing plate c911.

[0165] Then, the C scraping cylinder c325 drives the C scraping mechanism c310 to move left and scrape glue, so that a thin layer of glue is left on the C swing plate gluing surface c122. Then, the above actions are repeated to work in a cycle.

[0166] It should be noted that the structure of the above embodiment three, if the mutual position of the C swing gluing mechanism c100 and the C template mechanism c200 is changed, i.e., the C template mechanism c200 is turned over by 180 degrees and is arranged on the top of the C swing gluing mechanism c100, belongs to equivalent replacement and belongs to the protection scope of the present application.

[0167] It should be noted that the structure of the above embodiment three, if the C scraping mechanism c310 is changed to a silk printing mechanism or other mechanism that can apply a thin layer of glue on the C swing plate gluing surface c122, all belong to equivalent replacement and belong to the protection scope of the present application.

[0177] Preferably, as Figure 47 , Figure 50 , Figure 51 , Figure 52、 Figure 53 、 Figure 54 、 Figure 55 , the D cylinder gluing mechanism d100 is provided with a D glue uniformizing mechanism d2 on one side, preferably the D glue uniformizing mechanism d2 adopts a D glue scraping mechanism d310, the D glue scraping mechanism d310 comprises a D4 fixing part d311, a D5 fixing part d312, a D scraper lifting sliding block d313, a D scraper lifting guide rail d314, a D scraper lifting driving unit d315, a D scraper holder d317, a D scraper d318, preferably further comprises a D leakage prevention part d319, preferably the D scraper lifting driving unit d315 adopts a D scraper lifting cylinder d316. The D scraper lifting sliding block d313 is fixedly connected with the D4 fixing part d311, the D scraper lifting sliding block d313 is in sliding connection with the D scraper lifting guide rail d314, the D scraper lifting guide rail d314 is fixedly connected with the D scraper holder d317, the D scraper d318 is fixed on the D scraper holder d317, and the D leakage prevention part d319 is arranged at two ends of the D scraper d318; the cylinder body of the D scraper lifting cylinder d316 is fixed on the D4 fixing part d311, the piston shaft of the D scraper lifting cylinder d316 is fixedly connected with the D scraper holder d317, the D4 fixing part d311 is fixedly connected with the D5 fixing part d312, and the D5 fixing part d312 is fixedly connected with the D rack d1. The D scraper lifting cylinder d316 drives the D scraper holder d317 to ascend or descend.

[0178] The working process and working principle are as follows:

[0179] Firstly, the D scraper lifting cylinder d316 drives the D scraper holder d317 to descend, so that the D scraper d318 on the D scraper holder d317 is away from the D flat plate gluing surface d122; then the D moving cylinder d325 drives the D flat plate d121 to reach the first position; then the D scraper lifting cylinder d316 drives the D scraper holder d317 to ascend, so that the D scraper d318 on the D scraper holder d317 is close to the D flat plate gluing surface d122, and there is a small gap between the knife edge of the D scraper d318 and the D flat plate gluing surface d122.

[0180] Then the D-cylinder motor d132 drives the D-cylinder d125 to rotate, and at the same time, the D-moving cylinder d325 drives the D-plate d121 to move to the second position. In the above process, the rotating D-cylinder d125 brings the glue in the D-glue container d136 to the D-plate glue surface d122, so that a glue layer is formed on the D-plate glue surface d122. Preferably, in the above process, because there is a small gap between the blade edge of the D-scraper d318 and the D-plate glue surface d122, the above glue layer is scraped thin to form a thin layer of glue on the D-plate glue surface d122, and the excess glue is blocked by the D-scraper d318 and falls into the D-glue container d136; the D-leakage prevention piece d319 prevents glue from leaking out of the two ends of the D-scraper d318.

[0181] Then, when the D-moving cylinder d325 drives the D-plate d121 to reach the second position, a thin layer of glue is left on the D-plate glue surface d122.

[0182] Then, the D-mold plate lifting cylinder d236 drives the D-mold plate mechanism d200 and the mold plate 011 placed on it to rise, and when it rises to the end, the end face of the keyboard silica gel particle 021 in the mold plate positioning hole 012 on the mold plate 011 contacts the D-plate glue surface d122. Then, preferably, the D-air hole d221 on the D-male cavity assembly d220 is connected to compressed gas to blow up the keyboard silica gel particle 021 in the mold plate positioning hole 012 on the mold plate 011 placed on it, so that the end face of the keyboard silica gel particle 021 contacts the D-plate glue surface d122 more reliably, and after a delay, the D-11 disconnects the compressed gas.

[0183] Then, the D-air hole d221 on the D-male cavity assembly d220 switches to connect to vacuum to suck the keyboard silica gel particle 021 in the mold plate positioning hole 012 on the mold plate 011.

[0184] Then, the D-mold plate lifting cylinder d236 drives the D-mold plate mechanism d200 and the mold plate 011 placed on it to descend, so that the keyboard silica gel particle 021 in the mold plate positioning hole 012 on the mold plate 011 is separated from the D-plate glue surface d122, so that the end face of the keyboard silica gel particle 021 is glued (equivalent to printing glue); then, the D-air hole d221 is closed to disconnect the vacuum. After the mold plate 011 descends to the end, the mold plate 011 and the keyboard silica gel particle 021 placed on it which has been glued are transferred to the next process.

[0185] Then, another mold plate 011 with keyboard silica gel particles 021 placed on it is transferred to the D-male cavity assembly d220.

[0186] Next, the D scraper lifting cylinder d316 drives the D scraper frame d317 to descend, so that the D scraper d318 is separated from the D flat plate glue coating surface d122. Next, the D moving cylinder d325 drives the D flat plate d121 to move to the first position, and the D cylinder motor d132 also drives the D cylinder d125 to rotate reversely. When reaching the first position, the D scraper lifting cylinder d316 drives the D scraper frame d317 to ascend, so that the D scraper d318 is close to the D flat plate glue coating surface d122. Next, the above actions are repeated to work in cycles.

[0187] It should be noted that the above-mentioned D cylinder motor d132 can not be used; instead, a gear and rack mechanism or a synchronous wheel and synchronous belt mechanism or other similar mechanisms can be used in linkage with the D moving cylinder d325, so that the D cylinder d125 also rotates synchronously when the D moving cylinder d325 drives the D flat plate d121 to move. The above structure belongs to equivalent replacement.

[0188] It should be noted that the above-mentioned D moving cylinder d325 can not be used; instead, a gear and rack mechanism or a synchronous wheel and synchronous belt mechanism or other similar mechanisms can be used in linkage with the D cylinder motor d132, so that the D flat plate d121 also moves synchronously when the D cylinder motor d132 drives the D cylinder d125 to rotate. The above structure belongs to equivalent replacement.

[0189] Example Five: As Figures 60 to 63 , the keyboard silicone particle end face glue printing machine of the present application adopts the structure mode of the E template mechanism e200 above and the E flat plate glue coating mechanism e100 below, which comprises an E rack e1, wherein the E flat plate glue coating mechanism e100, the E glue leveling mechanism e2 and the E template mechanism e200 are arranged on the E rack e1, and the E template mechanism e200 is above the E flat plate glue coating mechanism e100. The E glue leveling mechanism e2 adopts an E glue scraping mechanism e310.

[0190] The E flat plate glue coating mechanism e100 comprises an E glue coating piece e3 and an E flat plate lifting mechanism e123, wherein the E flat plate lifting mechanism e123 comprises an E1 fixed plate e124, an E flat plate sliding block e133, an E flat plate guide rail e134 and an E flat plate lifting driving unit e131, preferably the E flat plate lifting driving unit e131 adopts an E flat plate lifting cylinder e132, the E glue coating piece e3 is an E flat plate e121, and the upper surface of the E flat plate e121 is an E flat plate glue coating surface e122.

[0191] The E flat plate lifting cylinder e132 drives the E flat plate e121 to ascend or descend. As Figure 61As shown, the E-plate lifting cylinder e132 drives the E-plate e121 to descend to the lowest position, which is called the lower position; Figure 62 As shown, the E-plate lifting cylinder e132 drives the E-plate e121 to rise to the uppermost position, which is called the upper position.

[0192] In the lower position, E side wing mechanisms e900 are provided on both sides of the E flat plate gluing mechanism e100. The E side wing mechanism e900 in this embodiment is similar to the side wing mechanisms of the second and third embodiments, and therefore will not be described in detail here.

[0193] The position of the E scraping mechanism e310 is shown in Figure 60 、 Figure 61 、 Figure 62 The E-type scraping mechanism e310 is also connected to the E-type moving mechanism e320. When the E-type plate lifting cylinder e132 drives the E-type plate e121 to descend to the lower position, the E-type moving mechanism e320 drives the E-type scraping mechanism e310 to move over the E-type plate's gluing surface e122 and the E-type wing mechanisms e900, applying a thin layer of glue to the E-type plate's gluing surface e122.

[0194] The E moving mechanism e320 described in this embodiment is similar to the corresponding mechanisms of the second and third embodiments, and therefore will not be described in detail here.

[0195] The E-template mechanism e200 is located above the E-plate gluing mechanism e100. The E-template mechanism e200 includes an E-A cavity assembly e220, an E-flip bearing seat unit e230, an E-flip shaft e231, an E-flip connector e234, an E-flip drive unit e232, and an E2 fixing plate e235. The E-A cavity assembly e220 is provided with E-holes e221. Preferably, the E-flip drive unit e232 utilizes an E-flip motor e233. The E-A cavity assembly e220 is fixedly connected to the E-flip connector e234, which is fixedly connected to the E-flip shaft e231. The E-flip shaft e231 is rotatably connected to the E-flip bearing seat unit e230. The E-flip bearing seat unit e230 is fixedly connected to the E2 fixing plate e235. The E-flip motor e233 is connected to a reducer, the reducer body is fixedly connected to the E2 fixing plate e235, and the reducer output shaft is fixedly connected to the E-flip shaft e231. A template 011 is provided on the E-A cavity assembly e220, and keyboard silicone beads 021 are placed in the template positioning holes 012 on the template 011.

[0196] like Figure 61, the E cavity component e220 and the template 011 arranged thereon are in a position where the end face of the keyboard silica gel particles 021 in the template positioning hole 012 faces upwards, referred to as a 0-degree position; as shown in Figure 62 , the E cavity component e220 and the template 011 arranged thereon are in a position where the end face of the keyboard silica gel particles 021 in the template positioning hole 012 faces downwards, referred to as a 180-degree position. The E turnover motor e233 drives the E cavity component e220 and the template 011 arranged thereon to rotate between the 0-degree position and the 180-degree position.

[0197] The E cavity component e220 can be arranged as one or symmetrically arranged as two.

[0198] It should be noted that the above-mentioned E turnover motor e233 can also not need to be connected to a speed reducer, but the body of the E turnover motor e233 is fixedly connected with the E2 fixed plate e235, and the rotating shaft of the E turnover motor e233 is fixedly connected with the E turnover rotating shaft e231. Alternatively, a cylinder plus a gear rack mechanism or a cylinder plus a synchronous belt synchronous wheel mechanism or other mechanisms can be used instead of the above-mentioned E turnover motor e233.

[0199] The working process and working principle are as follows:

[0200] First, the E flat plate lifting cylinder e132 drives the E flat plate e121 to descend to the lower position, and then the E turnover motor e233 drives the E cavity component e220 to turn to the 0-degree position. Then, the template 011 full of keyboard silica gel particles 021 is placed on the E cavity component e220 and fixed: at the same time, the E moving mechanism e320 drives the E glue scraping mechanism e310 to coat a thin layer of glue on the E flat plate glue coating surface e122.

[0201] Then, the E air hole e221 on the E cavity component e220 is connected to a vacuum, which sucks the template 011 and the keyboard silica gel particles 021 thereon; then the E turnover motor e233 drives the E cavity component e220 and the template 011 arranged thereon to turn from the 0-degree position to the 180-degree position, at which time the end face of the keyboard silica gel particles 021 in the template positioning hole 012 on the template 011 faces downwards and is opposite to the E flat plate glue coating surface e122.

[0202] Next, the E-plate e121 is driven upward by the E-lift cylinder. When it reaches the upper position, the E-plate's glued surface e122 contacts the end faces of the keyboard silicone particles 021 within the template positioning holes 012 on the template 011. Next, preferably, the E-air vent e221 on the E-cavity assembly e220 is disconnected from the vacuum and then reconnected with compressed gas. The compressed gas blows the keyboard silicone particles 021 within the template positioning holes 012 on the template 011 toward the E-plate's glued surface e122, ensuring more reliable contact between the end faces of the keyboard silicone particles 021 and the E-plate's glued surface e122. After a delay, the E-air vent e221 disconnects the compressed gas and reconnects the vacuum, sucking the keyboard silicone particles 021 into the template positioning holes 012.

[0203] Then, the E lifting cylinder drives the E plate e121 to descend, so that the glue-coated surface e122 of the E plate is separated from the keyboard silicone particles 021 in the template positioning hole 012 on the template 011, so that the end surface of the keyboard silicone particles 021 is stuck with glue (equivalent to printing glue).

[0204] When the E-lift cylinder drives the E-plate e121 down to the lower position, the E-flip motor e233 then flips the E-cavity assembly e220 and the template 011 placed on it from the 180-degree position to the 0-degree position. The E-air vent e221 then disconnects the vacuum. The template 011 and the glued keyboard silicone pellets 021 placed on it are then transferred to the next process.

[0205] Next, another template 011 with keyboard silica gel particles 021 is moved to the E-type cavity component e220. Then, the above steps are repeated to cycle the work.

[0206] It should be noted that the flipping mechanisms, the swinging mechanisms, the lifting mechanisms, or the moving mechanisms in the above embodiments may also be replaced by manipulators with the same effect, which is an equivalent transformation.

[0207] It should be noted that the above-mentioned keyboard silicone particle end surface printing machine can also be used in combination with a swing silicone particle machine. The keyboard silicone particles 021 in the template positioning holes 012 on the template 011 are automatically placed by the swing silicone particle machine, which also falls within the scope of protection of the present invention.

[0208] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any modifications, equivalent changes and modifications made to the above embodiments by any technician familiar with the profession without departing from the scope of the technical solution of the present invention shall fall within the scope of the technical solution of the present invention.
