Abstract

The invention relates to the technical field of acrylic processing, and discloses an automatic welding machine for acrylic thick plates and a method for using the same. The machine comprises a supporting mechanism, wherein the supporting mechanism also comprises a fixing plate. Aiming at the characteristics of different shapes of acrylic thick plates on the market, the invention provides a clamping mechanism inside the device. When the device is formally used, the acrylic thick plate is placed on the top of the placing plate, and the power of an electric telescopic rod and a heating machine is turned on. As the electric telescopic rod extends outward, the mounting plate moves outward along the inner wall of a rack track. At this time, a second gear rotates outward along the outer wall of the rack track synchronously. The force of the rotation of the second gear drives the first gear to rotate synchronously through a rotating column. The first gear drives the L-shaped racks at both ends to be squeezed toward the center of the device. The squeezing force generated by the L-shaped rack forces the piston plate to move along the inner wall of the air pressure box through a spring telescopic rod, so that a high-pressure environment is formed inside the air pressure box, and the air pressure plate and the clamping rotating block are forced to extend outward.

Description

Technical Field

[0001] The invention relates to the technical field of acrylic processing equipment, in particular to an automatic welding machine for acrylic thick plates and a use method thereof. Background Art

[0002] Acrylic, also known as special organic glass, is a replacement product of organic glass. Light boxes made of acrylic have the characteristics of good light transmittance, pure color, rich colors, beautiful and smooth appearance. Acrylic board is made of organic glass. When the joints are directly heated and welded using conventional high-temperature melting equipment, black marks will be left at the joints. Since most of them are transparent materials, which affects the appearance, they cannot be welded using conventional welding equipment.

[0003] Among them, due to the increasing market demand for acrylic sheets, the appearance of acrylic sheets will present various forms. Due to the irregular shape or curved structure, the clamp cannot effectively fix the welding workpiece, which may cause the workpiece to shake during welding, thereby affecting the welding effect of the acrylic sheet. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an automatic acrylic thick plate welding machine, comprising a support mechanism, the support mechanism also comprising a fixed plate, an electric telescopic rod is fixedly connected to the side wall of the fixed plate, and an end of the electric telescopic rod away from the fixed plate is fixedly connected to a mounting plate;

[0005] The clamping mechanism includes a plurality of air pressure boxes fixedly connected to the side wall of the mounting plate, a piston plate slidably connected to the inner wall of the plurality of air pressure boxes, and a spring telescopic rod fixedly connected to the side wall of the piston plate;

[0006] The hot melt mechanism comprises a heater fixedly connected to the inner wall of the through hole of the fixed plate, a scraper fixedly connected to the top of the heater, and a sliding heating plate slidably connected to the inner wall of the scraper.

[0007] Preferably, the supporting mechanism also includes a placing plate fixedly connected to the top of the mounting plate, the bottom of the placing plate is slidably connected to the top of the fixing plate, and the top of the fixing plate is fixedly connected with a gear rod track. This mechanism provides an installation position for subsequent mechanisms, which has a stabilizing effect during operation to ensure the normal operation of the equipment.

[0008] Preferably, the supporting mechanism also includes a thick acrylic plate placed on the top of the placement plate, the bottom of the fixed plate is fixedly connected to a supporting frame, and the inner wall of the gear rail is slidably connected to the outer wall of the mounting plate.

[0009] Preferably, the clamping mechanism also includes an L-shaped gear rod fixedly connected to the end of the spring telescopic rod away from the piston plate, a pneumatic plate is slidably connected to the inner wall of the pneumatic box, a clamping rotating block is rotatably connected to the inner wall of the pneumatic plate, and a limiting plate is fixedly connected to the side wall of the pneumatic box.

[0010] Preferably, the clamping mechanism also includes a rotating column rotatably connected to the inner wall of the through hole of the limit plate, the top of the rotating column is fixedly connected to a gear 1, the outer wall of the gear 1 is meshingly connected to the outer wall of the L-shaped gear rod, the end of the rotating column away from the gear 1 is fixedly connected to a gear 2, the outer wall of the gear 2 is meshingly connected to the outer wall of the gear rod track. In view of the different shapes of acrylic thick plates on the market, a clamping mechanism is provided inside the device. When the device is officially used, the acrylic thick plate is placed on the top of the placement plate, and the power of the electric telescopic rod and the heating machine is turned on. As the electric telescopic rod moves The mounting plate moves outward along the inner wall of the rack track. At this time, gear two rotates outward along the outer wall of the rack track synchronously. The force of gear two's rotation drives gear one to rotate synchronously through the rotating column. Gear one drives the L-shaped racks at both ends to squeeze toward the center of the equipment. The extrusion force generated by the L-shaped rack forces the piston plate to move along the inner wall of the air pressure box through the spring telescopic rod, so that a high-pressure environment is formed inside the air pressure box, and the air pressure plate and the clamping rotating block are forced to extend outward to clamp the outer wall of the acrylic thick plate. Among them, several air pressure plates will be close to the outer shape of the acrylic thick plate.

[0011] Preferably, the hot melt mechanism also includes a plastic plate fixedly connected to the top of the sliding heating plate, a control push rod is fixedly connected to the side wall of the mounting plate, a right-angle plate is fixedly connected to the end of the control push rod away from the mounting plate, and a rotating plate is rotatably connected to the outer wall of the sliding heating plate. Utilizing the characteristic of the sliding heating plate moving downward quickly, a plastic plate is arranged inside the equipment. When the acrylic thick plate is completed hot-melted, the plastic plate moves downward and stays on the top of the scraper to provide a plastic area for the welding position of the acrylic thick plate, so that when the softened acrylic thick plates are squeezed against each other, excess molten liquid will cling to the inner wall of the plastic plate to prevent the acrylic liquid from flowing out and causing an unstable connection. In addition, the mirror-like plastic plate can effectively reduce the stickiness of the molten liquid. In addition, after the welding position of the acrylic thick plate is cooled, the transparency of the position can be guaranteed to be high, and the transparency of the equipment will not be affected by the tortuosity of the acrylic surface.

[0012] Preferably, the hot melt mechanism also includes a roller rotatably connected to the bottom of the rotating plate, a baffle is fixedly connected to the side wall of the sliding heating plate, a push spring is fixedly connected to the outer wall of the sliding heating plate, and one end of the push spring away from the sliding heating plate is fixedly connected to the bottom of the fixed plate. After the clamping is completed, as the electric telescopic rod continues to push the mounting plate to move, the mounting plate synchronously drives the right-angle plate to move forward. During the movement, the inclined surface of the right-angle plate will contact the roller, and the rotating plate is restricted by the baffle. When the roller is squeezed by the right-angle plate, the roller will drive the rotating plate to move upward along the inner wall of the heating machine, presenting a Figure 8 The state shown in the figure, at this time, the acrylic thick plate on the top of the equipment will contact the outer wall of the sliding heating plate. After the port position of the acrylic thick plate softens, the electric telescopic rod continues to extend, and the roller will pass over the inclined surface of the right-angle plate and, pushed by the push spring, force the sliding heating plate to move downward along the inner wall of the heating machine to complete the hot melting of the acrylic thick plate. Finally, the two acrylic thick plates are clamped together by the electric telescopic rod to complete the welding process of the acrylic thick plates. Through the application of the above components and the characteristic of the sliding heating plate moving downward quickly, a scraper is provided inside the equipment to remove most of the impurities stuck to the outer wall of the sliding heating plate to avoid affecting the subsequent welding efficiency.

[0013] An acrylic thick plate automatic welding machine and a method of using the same include the following steps:

[0014] S1: Before using the present invention, place the acrylic thick plate on the top of the placement plate, and turn on the power of the electric telescopic rod and the heating machine. As the electric telescopic rod extends outward, the mounting plate moves outward along the inner wall of the rack rail;

[0015] S2: Gear 2 rotates outward along the outer wall of the gear rod track synchronously. The force of the rotation of gear 2 drives gear 1 to rotate synchronously through the rotating column. Gear 1 drives the L-shaped gear rods at both ends to squeeze toward the center of the equipment.

[0016] S3: The extrusion force generated by the L-shaped gear rod forces the piston plate to move along the inner wall of the air pressure box through the spring telescopic rod, so that a high-pressure environment is formed inside the air pressure box, and the air pressure plate and the clamping rotating block are forced to extend outward.

[0017] The present invention has the following beneficial effects:

[0018] (1) In view of the fact that acrylic thick plates on the market have different shapes, the present invention provides a clamping mechanism inside the device. When the device is officially used, the acrylic thick plate is placed on the top of the placement plate, and the power of the electric telescopic rod and the heating machine is turned on. As the electric telescopic rod extends outward, the mounting plate moves outward along the inner wall of the rack track. At this time, gear 2 rotates outward along the outer wall of the rack track synchronously. The force of the rotation of gear 2 drives gear 1 to rotate synchronously through the rotating column. Gear 1 drives the L-shaped racks at both ends to squeeze toward the center of the device. The squeezing force generated by the L-shaped rack forces the piston plate to move along the inner wall of the air pressure box through the spring telescopic rod, so that a high-pressure environment is formed inside the air pressure box, and the air pressure plate and the clamping rotating block are forced to extend outward to achieve clamping of the outer wall of the acrylic thick plate. Among them, several air pressure plates will be closely attached to the shape of the acrylic thick plate. Through the application of the above components, the device can clamp and position the strange shape, ensuring the stability of the dissolution angle during subsequent welding.

[0019] (2) After the clamping is completed, the electric telescopic rod continues to push the mounting plate to move. At this time, the mounting plate synchronously drives the right-angle plate to move forward. During the movement, the inclined surface of the right-angle plate will contact the roller. The rotating plate is restricted by the baffle plate, resulting in the roller being squeezed by the right-angle plate. The roller will drive the rotating plate to move upward along the inner wall of the heating machine, presenting the following Figure 8 The state shown in the figure, at this time, the acrylic thick plate on the top of the equipment will contact the outer wall of the sliding heating plate. After the port position of the acrylic thick plate softens, the electric telescopic rod continues to extend, and the roller will pass over the inclined surface of the right-angle plate and, pushed by the push spring, force the sliding heating plate to move downward along the inner wall of the heating machine to complete the hot melting of the acrylic thick plate. Finally, the two acrylic thick plates are clamped together by the electric telescopic rod to complete the welding process of the acrylic thick plates. Through the application of the above components and the characteristic of the sliding heating plate moving downward quickly, a scraper is provided inside the equipment to remove most of the impurities stuck to the outer wall of the sliding heating plate to avoid affecting the subsequent welding efficiency.

[0020] (3) The present invention utilizes the characteristic of the sliding heating plate moving downward quickly, and a plastic plate is arranged inside the equipment. When the acrylic thick plate is completed hot-melted, the plastic plate moves downward and stays on the top of the scraper, providing a plastic area for the acrylic thick plate welding position. When the softened acrylic thick plates are squeezed against each other, the excess molten liquid will adhere to the inner wall of the plastic plate, preventing the acrylic liquid from flowing out and causing an unstable connection. In addition, the mirror-like plastic plate can effectively reduce the stickiness of the molten liquid. In addition, after the acrylic thick plate is cooled, the transparency of the welding position can be guaranteed to be high, and the transparency of the equipment will not be affected by the tortuosity of the acrylic surface.

[0021] (4) After the equipment processing is completed, the worker takes out the material, and the electric telescopic rod drives the right-angle plate to reset. The sliding heating plate is pushed by the push spring to the lowest position. As the right-angle plate is reset, the vertical surface of the right-angle plate will contact the side of the rotating plate. Since a baffle is provided at one end of the rotating plate and not at the other end, when the two are in contact, the rotating plate will rotate along the outer wall of the sliding heating plate, so that the right-angle plate breaks through the restriction of the sliding heating plate, completing the reset of the equipment components, providing conditions for subsequent continuous processing, realizing fully automatic welding of the equipment, and reducing manual participation.

The bottom of the placing plate 104 is slidably connected to the top of the fixing plate 101. The top of the fixing plate 101 is fixedly connected with a gear rail 105. This mechanism provides an installation position for subsequent mechanisms, which has a stabilizing effect during operation to ensure the normal operation of the equipment.

[0038] The supporting mechanism 1 further comprises an acrylic thick plate 106 placed on the top of the placing plate 104 , a supporting frame 107 is fixedly connected to the bottom of the fixing plate 101 , and the inner wall of the rack rail 105 is slidably connected to the outer wall of the mounting plate 103 .

[0039] For example 2, please refer to Figure 4 - Figure 8 The present invention is an automatic welding machine for thick acrylic plates. Based on the first embodiment, the clamping mechanism 2 also includes an L-shaped gear rod 204 fixedly connected to the end of the spring telescopic rod 203 away from the piston plate 202, a pressure plate 205 is slidably connected to the inner wall of the pressure box 201, a clamping rotating block 206 is rotatably connected to the inner wall of the pressure plate 205, and a limiting plate 207 is fixedly connected to the side wall of the pressure box 201.

[0040] The clamping mechanism 2 also includes a rotating column 208 rotatably connected to the inner wall of the through hole of the limit plate 207, a gear 209 is fixedly connected to the top of the rotating column 208, the outer wall of the gear 209 is meshed with the outer wall of the L-shaped gear rod 204, and the end of the rotating column 208 away from the gear 209 is fixedly connected to the gear 210, and the outer wall of the gear 210 is meshed with the outer wall of the gear rod track 105. In view of the different shapes of acrylic thick plates on the market, a clamping mechanism 2 is provided inside the device. When the device is officially used, the acrylic thick plate 106 is placed on the top of the placement plate 104, and the power of the electric telescopic rod 102 and the heating machine 301 is turned on. As the electric telescopic rod 102 extends outward, the installation The plate 103 moves outward along the inner wall of the rack track 105, and at this time, the gear 2 210 synchronously rotates outward along the outer wall of the rack track 105. The force of the rotation of the gear 2 210 drives the gear 1 209 to rotate synchronously through the rotating column 208, and the gear 1 209 drives the L-shaped racks 204 at both ends to be squeezed toward the center of the equipment. The squeezing force generated by the L-shaped rack 204 forces the piston plate 202 to move along the inner wall of the air pressure box 201 through the spring telescopic rod 203, so that a high-pressure environment is formed inside the air pressure box 201, and forces the air pressure plate 205 and the clamping rotating block 206 to extend outward, thereby clamping the outer wall of the acrylic thick plate 106, wherein several air pressure plates 205 will be close to the outer shape of the acrylic thick plate 106.

[0041] The hot melt mechanism 3 also includes a plastic plate 304 fixedly connected to the top of the sliding heating plate 303, a control push rod 305 fixedly connected to the side wall of the mounting plate 103, a right-angle plate 306 fixedly connected to the end of the control push rod 305 away from the mounting plate 103, and a rotating plate 307 rotatably connected to the outer wall of the sliding heating plate 303. The plastic plate 304 is arranged inside the device by utilizing the characteristic of the sliding heating plate 303 moving downward quickly. When the acrylic thick plate 106 is hot-melted, the plastic plate 304 moves downward and stays on the top of the scraper 302, providing a plastic area for the welding position of the acrylic thick plate 106. When the softened acrylic thick plates 106 are squeezed against each other, the excess melt will cling to the inner wall of the plastic plate 304, preventing the acrylic liquid from flowing out and causing an unstable connection. In addition, the mirror-like plastic plate 304 can effectively reduce the stickiness of the melt. In addition, after cooling, the welding position of the acrylic thick plate 106 can ensure that the transparency of the position is high, and the transparency of the equipment will not be affected by the tortuosity of the acrylic surface.

[0042] The hot melt mechanism 3 also includes a roller 308 rotatably connected to the bottom of the rotating plate 307, a baffle 309 is fixedly connected to the side wall of the sliding heating plate 303, and a push spring 310 is fixedly connected to the outer wall of the sliding heating plate 303.

After the clamping is completed, as the electric telescopic rod 102 continues to push the mounting plate 103 to move, the mounting plate 103 simultaneously drives the right-angle plate 306 to move forward. During the movement, the inclined surface of the right-angle plate 306 will contact the roller 308, and the rotating plate 307 is restricted by the baffle 309. As a result, when the roller 308 is squeezed by the right-angle plate 306, the roller 308 will drive the rotating plate 307 to move upward along the inner wall of the heating machine 301, presenting a Figure 8 The state shown in the figure, at this time, the acrylic thick plate 106 on the top of the equipment will contact the outer wall of the sliding heating plate 303. After the port position of the acrylic thick plate 106 softens, the electric telescopic rod 102 continues to extend, and the roller 308 will pass over the inclined surface of the right-angle plate 306, and under the push of the push spring 310, the sliding heating plate 303 is forced to move downward along the inner wall of the heating machine 301 to complete the hot melting of the acrylic thick plate 106. Finally, the two acrylic thick plates 106 are clamped with each other under the push of the electric telescopic rod 102 to complete the welding process of the acrylic thick plates 106. Through the application of the above components and the characteristic of the sliding heating plate 303 moving downward quickly, a scraper 302 is arranged inside the equipment to remove most of the impurities adhering to the outer wall of the sliding heating plate 303 to avoid affecting the subsequent welding efficiency.

[0043] The welding method of the welding device comprises the following steps:

[0044] S1: Before using the present invention, the acrylic thick plate 106 is placed on the top of the placement plate 104, and the power of the electric telescopic rod 102 and the heating machine 301 is turned on.

[0046] S3: The extrusion force generated by the L-shaped gear rod 204 forces the piston plate 202 to move along the inner wall of the air pressure box 201 through the spring telescopic rod 203, so that a high-pressure environment is formed inside the air pressure box 201, and forces the air pressure plate 205 and the clamping rotating block 206 to extend outward.

[0047] A specific application of this embodiment is as follows: in view of the different shapes of acrylic thick plates on the market, the present invention is provided with a clamping mechanism 2 inside the device. When the device is officially used, the acrylic thick plate 106 is placed on the top of the placement plate 104, and the power of the electric telescopic rod 102 and the heating machine 301 is turned on. As the electric telescopic rod 102 extends outward, the mounting plate 103 moves outward along the inner wall of the rack track 105. At this time, the gear 2 210 synchronously rotates outward along the outer wall of the rack track 105. The force of the rotation of the gear 2 210 drives the gear 1 209 to rotate synchronously through the rotating column 208. The gear 1 209 drives the L-shaped racks 204 at both ends to squeeze toward the center of the device. The squeezing force generated by the L-shaped rack 204 forces the piston through the spring telescopic rod 203. The plate 202 moves along the inner wall of the air pressure box 201, so that a high-pressure environment is formed inside the air pressure box 201, and the air pressure plate 205 and the clamping rotating block 206 are forced to extend outward to clamp the outer wall of the acrylic thick plate 106, wherein a plurality of air pressure plates 205 will be closely attached to the outer shape of the acrylic thick plate 106. After the clamping is completed, as the electric telescopic rod 102 continues to push the mounting plate 103 to move, the mounting plate 103 simultaneously drives the right-angle plate 306 to move forward. During the movement, the inclined surface of the right-angle plate 306 will contact the roller 308, wherein the rotating plate 307 is restricted by the baffle plate 309, resulting in that when the roller 308 is squeezed by the right-angle plate 306, the roller 308 will drive the rotating plate 307 to move upward along the inner wall of the heating machine 301, presenting as shown in the figure. Figure 8The state shown in the figure, at this time, the acrylic thick plate 106 on the top of the equipment will contact the outer wall of the sliding heating plate 303. After the end position of the acrylic thick plate 106 softens, the electric telescopic rod 102 continues to extend, and the roller 308 will pass over the inclined surface of the right-angle plate 306, and under the push of the push spring 310, the sliding heating plate 303 is forced to move downward along the inner wall of the heating machine 301 to complete the hot melting of the acrylic thick plate 106. Finally, the two acrylic thick plates 106 are clamped with each other under the push of the electric telescopic rod 102. The welding process of the acrylic thick plate 106 is completed by applying the above components and utilizing the characteristic of the sliding heating plate 303 moving downward quickly. A scraper 302 is arranged inside the device to remove most of the impurities adhering to the outer wall of the sliding heating plate 303. The characteristic of the sliding heating plate 303 moving downward quickly is utilized. A plastic plate 304 is arranged inside the device. When the acrylic thick plate 106 is melted, the plastic plate 304 moves downward and stays on the top of the scraper 302, providing a plastic area for the welding position of the acrylic thick plate 106. When the softened acrylic thick plates 106 are squeezed against each other, the excess melt will cling to the inner wall of the plastic plate 304, preventing the acrylic liquid from flowing out and causing unstable connection. In addition, the mirrored plastic plate 304 can effectively reduce the stickiness of the melt. After cooling, the welding position of the acrylic thick plate 106 can ensure that the transparency of the position is high, and the transparency of the equipment will not be affected by the tortuosity of the acrylic surface. After completing the equipment processing, the worker takes out the material, and the electric telescopic rod 102 drives the right-angle plate 306 to reset, and the sliding The heating plate 303 is in the lowest position under the push of the push spring 310. As the right-angle plate 306 is reset, the vertical surface of the right-angle plate 306 will contact the side of the rotating plate 307. Since a baffle 309 is provided at one end of the rotating plate 307 and not at the other end, when the two are in contact, the rotating plate 307 will rotate along the outer wall of the sliding heating plate 303, so that the right-angle plate 306 breaks through the restriction of the sliding heating plate 303, completing the component reset of the equipment, realizing fully automatic welding of the equipment, and reducing manual participation.
