Description

Technical Field

[0001] The invention relates to the technical field of glass product production, and in particular to a flexible contact glass product production and processing device. Background Art

[0002] Glass spray painting and drying belongs to the refined glass production process. The method of glass spray painting and drying mainly includes cleaning and drying, coating, baking, cooling and other steps. ‌Cleaning and drying: Before the bottle is produced, it must be cleaned. ‌First, remove the grease and dirt on the surface of the glass by soaking in an alkaline solution. ‌Then, the bottle is dried in a high-temperature dryer. ‌Coating: Use special spraying equipment to spray paint on the glass surface. ‌Baking: Put the painted glass bottle into a high-temperature oven for heating. ‌In this process, the paint will solidify and form a smooth, wear-resistant and chemical-resistant layer. ‌Cooling: After baking, take the bottle out of the oven and cool it at room temperature. These steps ensure that the glass can form a uniform, firm and durable coating after painting, while ensuring the quality of the coating and the beauty of the glass.

[0003] In actual production of the prior art, there are problems in the baking process: depending on the thickness of the paint sprayed, drip marks of varying degrees will appear before the paint is completely dried, reducing the yield rate of the glass.

[0004] The Chinese utility model patent with publication number CN207793078U: A glass cup spray paint drying system discloses a design with a rotating track, a glass cup support seat for placing the glass cup is installed on the rotating track, a heating zone is provided on the rotating track, and an isolation cover is provided on the heating zone. A heating pipe is provided in the heating zone, and an inlet and an outlet are respectively provided at both ends of the isolation cover, a blower is provided on the inlet, and an exhaust fan is provided on the outlet, so as to achieve the drying effect of the glass cup baking paint in the most traditional way; The Chinese utility model patent with publication number CN215088276U: A manual spray paint machine for processing glass cups discloses a technical solution of using a heating wire to generate hot air and then drying the spray paint.

[0005] The above patents are unable to effectively solve the technical problem of low glass yield rate caused by drip marks in the prior art, so the field is in urgent need of a flexible contact glass product production and processing device to solve the problems existing in the prior art. Summary of the invention

[0006] The object of the present invention is to provide a flexible contact glass product production and processing device to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a flexible contact glass product production and processing device, comprising a drying box and a hot air pipe for providing a high-temperature airflow into the drying box, and a cold air pipe, wherein the hot air pipe is installed in the upper half of the inner wall of one side of the drying box, and the cold air pipe is installed in the lower half of the inner wall of the drying box on the same side as the hot air pipe; the hot air pipe and the cold air pipe are both installed with horizontally oriented nozzles; A column is fixedly installed on the bottom surface of the drying box, a robot arm is installed on the top of the column, a clamp is installed on the end of the robot arm away from the column, and the glass is clamped on the end of the clamp away from the robot arm.

[0008] The temperature difference between the gases ejected from the hot air duct and the cold air duct is less than 15°C.

[0009] By adopting the above technical scheme, the painted glass cup is clamped by a clamp, and the robot arm joints are controlled by programming to keep the glass cup moving. The automatic moving trajectory of the glass cup is ABCDEFGHA, which is repeated over and over again. During the movement of the glass cup, due to the twisting action of the robot arm joints, the glass cup will not only change its position, but also the direction of its own cup mouth will change accordingly, so that the glass cup can be blown against the wind in all directions, with high drying efficiency, and it is not easy to produce drip marks before the paint surface is dry, thereby improving the quality of the glass cup. Since the present scheme is designed with hot air ducts and cold air ducts at the same time, the air flow temperature in the upper half of the internal space of the drying box is higher than that in the lower half. The glass cup is efficiently baked and air-dried in the A / D / E / H areas of the upper half, and is cooled in the B / C / F / G areas of the lower half to reduce the activity of the paint surface molecules, quickly set the shape, and further reduce the probability of drip marks.

[0010] As a preferred embodiment, the clamp includes a connecting block with one end fixedly connected to the robot arm, and at least three leaf springs are fixedly installed in a circular array on the side wall of the connecting block at one end away from the robot arm. A clamping plate is fixedly installed at one end of the leaf spring away from the connecting block, and all the clamping plates jointly apply force to clamp the outer wall of the glass cup.

[0011] As a preferred solution, the clamping plate is recessed in the middle in the vertical direction away from the glass. For glasses with irregular wall shapes, such as glasses with a mouth diameter larger than the bottom diameter, the recess can be used to clamp the mouth of the glass, making it difficult for the glass to fall out of the clamp and providing high clamping stability.

[0012] As a preferred embodiment, at least three tension springs are installed in a circular array at one end of the connecting block away from the robot arm, and all the tension springs are connected and fixed to the same iron locking plate at one end away from the connecting block, and a movable groove is provided through the locking plate near the clamping plate area, and the clamping plate passes through the movable groove, and the vertical section of the clamping plate near one end of the leaf spring is a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid is located on the side away from the leaf spring; the side wall of the clamping plate away from the glass cup is tightly attached to the side wall of the movable groove away from the glass cup, so that the locking plate moves in the direction of the connecting block, and can apply pressure to the clamping plate in the direction of the glass cup. Since the fulcrum is located on the leaf spring, all the clamping plates away from the leaf spring are easily pressed by the locking plate and approach each other, so that the glass cup can be clamped more stably. The fulcrum is designed on the leaf spring, and the force arm is short, which can avoid the locking plate from suddenly applying force, causing the glass cup to be subjected to excessive force, and the glass cup is flexibly clamped with force, and the protection is good; As a preferred solution, a mounting groove is provided in the center of the connecting block, and an electromagnet is fixedly installed in the mounting groove. The electromagnet and the robot arm are connected to the same controller outside, and the opening and closing of the electromagnet are controlled by the controller. The magnetic force change of the electromagnet is controlled by programming: when it is opened, the magnetic force is slowly strengthened and lasts for 3 seconds; when it is closed, the magnetic force is slowly weakened and lasts for 3 seconds. The flexible clamping of the glass is realized.

[0013] By adopting the above technical solution, the glass to be dried is placed between all the clamping plates, the electromagnet is started, the locking plate is attracted by the mounting groove and moves in the direction of the mounting groove, and then the clamping plate is pressed in the direction of the glass to complete the flexible clamping of the glass. After the clamping is completed, the glass is blown and dried inside the drying box.

[0014] As a preferred solution, a sliding rod is fixedly installed on one end of the locking plate near the tension spring, and a limiting sleeve is fixedly installed on the side wall of the connecting block. The sliding rod passes through the limiting sleeve and is slidably connected to the limiting sleeve. The sliding rod can perform piston motion in the limiting sleeve. The above solution can improve the stability of the locking plate displacement, enable all clamping plates to perform clamping actions synchronously, and further improve the clamping stability.

[0015] As a preferred solution, the column is made of steel, and the longest span of the column in the horizontal direction is less than 5 cm, which can reduce the occupied space of the movable glass, improve the freedom of the moving trajectory of the glass, and facilitate further research and development of a more suitable moving trajectory.

[0016] As a preferred solution, in the horizontal direction, the side of the clamping plate close to the glass is concave, which can accommodate a large number of glass shapes and ensure high clamping stability.

[0017] As a preferred solution, the drying box has no side wall on the side away from the hot air duct, forming a window, and a baffle is installed on the upper part of the window. The baffle can block the hot air to lock the temperature and improve the utilization efficiency of the hot air. The cold air can flow out directly from under the baffle to avoid affecting the hot air temperature and to avoid the formation of condensation droplets at the junction of the hot and cold air.

[0018] As a preferred solution, a flow slot is left above the baffle, so that a small amount of hot air can flow out from the flow slot, reducing the air pressure in the upper part of the drying box and avoiding the occurrence of hot and cold air convection.

[0019] As a preferred solution, the top end of the baffle is hingedly mounted on the window to improve the openness of the internal space of the drying box in the non-production stage.

[0020] As a preferred solution, a rubber layer is attached to a side of the clamping plate close to the glass. Beneficial Effects

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 10 The embodiment 1 shown is a flexible contact glass product production and processing device, including a drying box 101 and a hot air duct 102 for providing high-temperature airflow into the drying box 101, and also including a cold air duct 103. The hot air duct 102 is installed in the upper half of the inner wall of one side of the drying box 101, and the cold air duct 103 is installed in the lower half of the inner wall of the drying box 101 on the same side as the hot air duct 102; horizontally-oriented nozzles 106 are installed on both the hot air duct 102 and the cold air duct 103; the hot air duct 102 is connected to an external high-temperature gas supply device, and the cold air duct 103 is connected to an external low-temperature gas supply device.

[0030] A column 201 is fixedly installed on the bottom surface of the drying box 101, a robot arm 202 is installed on the top of the column 201, a clamp is installed on the end of the robot arm 202 away from the column 201, and the end of the clamp away from the robot arm 202 clamps the glass 601.

[0031] The temperature difference between the gases ejected from the hot air pipe 102 and the cold air pipe 103 is 10° C., so as to prevent the paint surface of the dried glass cup 601 from being subjected to alternating hot and cold temperatures due to the high temperature difference and thus causing cracks.

[0032] like Figure 9-10As shown, by adopting the above technical solution, the painted glass 601 is clamped by a clamp, and the joints of the robot arm 202 are controlled by programming to keep the glass 601 in a moving state. The automatic moving trajectory of the position of the glass 601 is ABCDEFGHA, which is repeated. During the movement of the glass 601, due to the twisting effect of the joints of the robot arm 202, the glass 601 will not only change its position, but also the direction of its own cup mouth will change accordingly, so that the glass 601 can be swept against the wind in all directions, with high drying efficiency, and it is not easy to produce drip marks before the paint surface is dry, thereby improving the quality of the glass 601; because the present solution is designed with a hot air duct 102 and a cold air duct 103 at the same time, the air flow temperature of the upper half of the internal space of the drying box 101 is higher than that of the lower half, and the glass 601 is efficiently baked and air-dried in the A / D / E / H area of ​​the upper half, and is cooled in the B / C / F / G area of ​​the lower half to reduce the activity of the paint surface molecules, quickly set the shape, and further reduce the probability of drip marks.

[0033] The clamp includes a connecting block 301, one end of which is fixedly connected to the robot arm 202. Three leaf springs 302 are fixedly installed in a circular array on the side wall of the connecting block 301 away from the robot arm 202. A clamping plate 303 is fixedly installed on the end of the leaf spring 302 away from the connecting block 301. All the clamping plates 303 jointly apply force to clamp the outer wall of the glass cup 601.

[0034] The middle part of the clamping plate 303 in the vertical direction is concave away from the glass 601. For a glass 601 with a mouth diameter larger than the bottom diameter, the concave portion can be used to cooperate and clamp the mouth of the glass, so that the glass 601 is not easily separated from the clamp, and the clamping stability is high.

[0035] At least three tension springs 403 are installed in a circular array at one end of the connecting block 301 away from the robot arm 202. All tension springs 403 are connected and fixed to the same iron locking plate 401 at one end away from the connecting block 301. The locking plate 401 is provided with a movable groove 402 near the clamping plate 303. The clamping plate 303 passes through the movable groove 402. Figure 8As shown, the vertical section of the clamping plate 303 near one end of the leaf spring 302 is a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid is located on the side away from the leaf spring 302; the side wall of the clamping plate 303 away from the glass 601 is in close contact with the side wall of the movable groove 402 away from the glass 601, so that the locking plate 401 moves in the direction of the connecting block 301, and can apply pressure to the clamping plate 303 in the direction of the glass 601. Since the fulcrum is located on the leaf spring 302, all the clamping plates 303 away from the leaf spring 302 are easily pressed by the locking plate 401 and approach each other, so that the glass 601 can be clamped more stably. The fulcrum is designed on the leaf spring 302, and the force arm is short, which can prevent the locking plate 401 from suddenly applying force, causing the glass 601 to be subjected to excessive force, and the glass 601 is flexibly clamped with force, and the protection is good. The center of the connecting block 301 is provided with an installation slot 404, in which an electromagnet 405 is fixedly installed. The electromagnet 405 and the robot arm 202 are connected to the same controller outside. The opening and closing of the electromagnet 405 are controlled by the controller, and the magnetic force change of the electromagnet 405 is controlled by programming: when it is opened, the magnetic force is slowly strengthened and lasts for 3 seconds; when it is closed, the magnetic force is slowly weakened and lasts for 3 seconds. The flexible clamping of the glass 601 is realized.

[0036] By adopting the above technical solution, the glass cup 601 to be dried is placed between all the clamping plates 303, and the electromagnet 405 is started. The locking plate 401 is attracted by the installation groove 404 and moves in the direction of the installation groove 404, thereby applying pressure to the clamping plate 303 in the direction of the glass cup 601 to complete the flexible clamping of the glass cup 601. After the clamping is completed, the glass cup 601 is blown and dried inside the drying box 101.

[0037] A sliding rod 502 is fixedly installed on one end of the locking plate 401 near the tension spring 403, and a limiting sleeve 501 is fixedly installed on the side wall of the connecting block 301. The sliding rod 502 passes through the limiting sleeve 501 and is slidably connected to the limiting sleeve 501. The sliding rod 502 can perform piston motion in the limiting sleeve 501. The above scheme can improve the stability of the displacement of the locking plate 401, enable all clamping plates 303 to perform clamping actions synchronously, and further improve the clamping stability.

[0038] The column 201 is made of steel, and the longest span of the column 201 in the horizontal direction is 4 cm, which can reduce the occupied range of the movable space of the glass 601, improve the freedom of the moving trajectory of the glass 601, and facilitate further research and development of a more suitable moving trajectory in the later stage.

[0039] In the horizontal direction, the side of the clamping plate 303 close to the glass 601 is concave, which can accommodate the shape of the glass 601 with a large base number, thereby achieving high clamping stability.

[0040] The drying box 101 has no side wall on the side away from the hot air duct 102, forming a window. A baffle 104 is installed on the upper part of the window. The baffle 104 can block the hot air, lock the temperature, and improve the utilization efficiency of the hot air. The cold air can flow out directly from under the baffle 104 to avoid affecting the hot air temperature and to avoid condensation droplets at the junction of the hot and cold air.

[0041] A flow slot 105 is left above the baffle 104, so that a small amount of hot air can flow out from the flow slot 105, reducing the air pressure in the upper part of the drying box 101 and avoiding the occurrence of hot and cold air convection.

[0042] The top of the baffle 104 is hingedly mounted on the window to improve the openness of the inner space of the drying box 101 in the non-production stage.

[0043] In another embodiment, the hypotenuse of the right-angled trapezoid is located on the side close to the leaf spring 302, and the side wall of the movable groove 402 close to the glass cup 601 is in close contact with the clamping plate 303. The principle of use is changed as follows: the locking plate 401 moves in the direction of the electromagnet 405, and the movable groove 402 can apply outward pressure to the clamping plate 303 to expand the distance between the clamping plates 303. By adopting this embodiment, the clamping plate 303 can be penetrated into the mouth of the glass cup 601, and the inner wall of the glass cup 601 is supported by the clamping plate 303 applying force outward, thereby realizing the fixing function of the glass cup 601 and improving the drying process range applicable to this scheme.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
