Description

Technical Field

[0001] The invention relates to a method for detecting the sealing performance of a tail plug of a glass glue bottle, in particular to a system for detecting the sealing performance of a tail plug of a glass glue bottle and a tail plug installation process. Background Art

[0002] The current glass glue bottle consists of a bottle body and a tail plug. The cooperation between the tail plug and the bottle body is equivalent to the cooperation between the piston and the cylinder, so as to seal the glass glue in the bottle body and squeeze out the glass glue in the bottle body by pushing the tail plug. Therefore, the sealing performance between the tail plug and the inner wall of the bottle body is very important. The original control method is to ensure the fixedness and stability of the outer diameter of the tail plug and the inner diameter of the glue bottle. However, due to the structural characteristics of the bottle body and the tail plug, it is difficult to control the measurement of their dimensional parameters.

[0003] Among them, the tail plug is a cone with multiple sealing lines with gradually increasing outer diameters from top to bottom. The reading using a vernier caliper is inaccurate. In addition, the wall thickness of the tail plug is relatively thin, and it is made of plastic injection molding, which has cooling and post-shrinkage deformation. Therefore, using tools such as vernier calipers to measure and control its size will be laborious, inefficient and inaccurate. The bottle body is a cylindrical container with a depth of more than 20CM. The most accurate measuring tool for measuring its inner diameter is the inner diameter percentage / micrometer. This tool is expensive and difficult to operate. In addition, the bottle body is a deep cavity product, and the inner diameter of each cross-section from top to bottom is not completely consistent (with a slight demolding taper), so the inner diameter ruler cannot meet the measurement requirements. Therefore, judging whether it is qualified by measurement is obviously lacking.

[0004] In addition, the quality of the glass glue bottle is not only affected by the sealing between the tail plug and the inner wall of the bottle, but also related to the smoothness of the relative movement between the tail plug and the bottle body. In the daily use of glass glue, two situations may be encountered: 1. After the glass glue is squeezed out and used, there is glass glue remaining on the outer edge of the tail plug, which indicates that the sealing is not good; 2. The glass glue is more difficult to extrude, indicating that the friction between the tail plug and the bottle body is too large. Summary of the invention

[0005] The purpose of the present invention is to provide a glass glue bottle tail plug sealing detection system which has a simple and reasonable structure and is easy to operate.

[0006] The object of the present invention is achieved in that: A glass glue bottle tail plug sealing detection system comprises a force measuring device and a computer. The force measuring device is used to measure the force of the tail plug when it is in the sealing section position and / or moving in the bottle body, and the computer is used to record the force data.

[0007] The purpose of the present invention can also be solved by the following technical measures: As a more specific solution, the force measuring device is a tension measuring device, which includes a base, a fixed seat, a pull rod, a tension sensor, a lifting mechanism and a controller. The controller is used to control the movement of the lifting mechanism and collect data from the tension sensor. The controller is provided with a data transmission port, which is communicatively connected to the computer; the fixed seat and the lifting mechanism are arranged on the base, the pull rod is connected to the lifting mechanism through the tension sensor, and the tail plug is inserted into the bottle body and connected between the pull rod and the fixed seat.

[0008] As a further solution, the force measuring device is a pressure force measuring device, which includes a base, a fixed seat, a push rod, a pressure sensor, a lifting mechanism and a controller. The controller is used to control the movement of the lifting mechanism and collect data from the pressure sensor. The controller is provided with a data transmission port, which is communicatively connected to the computer; the fixed seat and the lifting mechanism are arranged on the base, the push rod is connected to the lifting mechanism through the pressure sensor, and the tail plug is inserted into the bottle body and connected between the push rod and the fixed seat.

[0009] Another object of the present invention is to provide a glass glue bottle tail plug installation process which is simple to operate, ensures that the tail plugs and bottle bodies of the same batch can be arbitrarily combined and paired, and is convenient for controlling product quality.

[0010] Another object of the present invention is achieved like this: A process for installing a tail plug for a glass glue bottle comprises placing the tail plug into the bottle body, and then using a force measuring device to measure and record the force applied to the tail plug when it moves in the sealing section and / or different positions in the bottle body, and comparing the measured force with the corresponding parameters of qualified products to determine whether the product is qualified.

[0011] As a further solution, the combination of the tail plug and the bottle body is as follows: select the smallest inner diameter bottle body, the largest inner diameter bottle body, the largest outer diameter tail plug, and the smallest outer diameter tail plug from the bottle bodies and tail plugs processed for the first time in each shift, and then test the smallest inner diameter bottle body and the largest outer diameter tail plug together, and test the largest inner diameter bottle body and the smallest outer diameter tail plug together; if the corresponding parameters of the inspected product do not meet the corresponding parameters of the qualified product, find out the molds corresponding to the relevant bottle bodies and tail plugs, stop using them first, and then test them in the above manner. If they meet the requirements, they can be produced and assembled first to avoid a complete shutdown.

[0012] As a further solution, the outer diameter of the tail plug is measured at its bottom, or by measuring the outer diameters at both ends of the tail plug and taking the average value as the measured outer diameter of the tail plug, or by screening the tail plugs with the largest and smallest outer diameters through a copper sleeve of a fixed size. The inner diameter of the bottle body is measured at its bottom; or by measuring the inner diameters at both ends of the inner cavity of the bottle body and taking the average value as the measured inner diameter of the bottle body; or by screening the bottle body with the largest and smallest inner diameters through a copper rod of a fixed size.

[0013] As a further solution, the force measuring device is a tension or pressure testing device, which places the tail plug into the tail of the bottle body, pulls or pushes the tail plug toward the head of the bottle body, and records the static friction overcome by the tail plug when it moves from static to moving, and judges the sealing between the tail plug and the bottle body by the static friction; in addition, the change in dynamic friction during the movement of the tail plug from the tail of the bottle body to the head of the bottle body is recorded to judge the feel of the glass glue bottle when it is used; and the change in dynamic friction is recorded in a curve for easy monitoring and control.

[0014] As a further option, the number of measurements can be increased depending on the amount of work done per shift.

[0015] The beneficial effects of the present invention are as follows: (1) The present invention applies tensile / pressure testing equipment to sealing detection, which is convenient for production workshops to check product quality in a timely and independent manner. In combination with the detection method, extreme combinations are put together to check whether other combinations will cause problems, thereby ensuring production quality. In addition, data can be generated to track the quality of production equipment and production batches.

[0016] (2) The present invention uses a force measuring device to measure the friction force of the tail plug moving in the sealing section of the bottle body to determine the sealing performance of the tail plug and the bottle body. In addition, by measuring the change in the friction force of the tail plug moving in the bottle body, this structure can not only easily obtain effective data, but also obtain the force of the tail plug moving inside the bottle body to determine the feel of the glass glue bottle when extruding glass glue. When all the parameters of the product are met, it is ensured that the product application makes the terminal construction personnel feel the touch and the stability of the glue discharge during construction.

[0017] (3) The present invention performs sampling during the first processing of each processing shift, and can use fixed tools (such as copper sleeves and copper rods of fixed sizes) to match the tail plug and the bottle body respectively, and quickly select the smallest inner diameter bottle body, the largest inner diameter bottle body, the largest outer diameter tail plug, and the smallest outer diameter tail plug, and then test the smallest inner diameter bottle body and the largest outer diameter tail plug together, and test the largest inner diameter bottle body and the smallest outer diameter tail plug together. If they meet the relevant airtight requirements, subsequent production can be carried out to avoid the occurrence of defective products.

[0018] (4) The force measuring device of the present invention can transmit the measurement to a computer, and the force data (friction force) can be converted into a curve by the computer as a basis for monitoring and control. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: See also Figure 1As shown, a glass glue bottle tail plug sealing detection system includes a force measuring device and a computer 5.

[0021] The force measuring device is a pressure force measuring device, which includes a base 3, a fixed seat 31, a push rod 7, a pressure sensor 8, a lifting mechanism 6 and a controller 4. The controller 4 is used to control the movement of the lifting mechanism 6 and collect data from the pressure sensor 8. The controller 4 is provided with a data transmission port, which is connected to the computer 5 in communication. The fixed seat 31 and the lifting mechanism 6 are arranged on the base 3, the push rod 7 is connected to the lifting mechanism 6 through the pressure sensor 8, and the tail plug 2 is inserted into the bottle body 1 and connected between the push rod 7 and the fixed seat 31. The lifting mechanism 6 includes an electric telescopic rod, the upper end of which is provided with a top plate 61, and the push rod 7 is connected to the bottom of the top plate 61 through the pressure sensor 8. Alternatively, the force measuring device is a tension measuring device, which includes a base, a fixed seat, a pull rod, a tension sensor, a lifting mechanism and a controller. The controller is used to control the movement of the lifting mechanism and collect data from the tension sensor. The controller is provided with a data transmission port, which is communicatively connected to the computer 5. The fixed seat and the lifting mechanism are arranged on the base, the pull rod is connected to the lifting mechanism through the tension sensor, and the tail plug 2 is inserted into the bottle body 1 and connected between the pull rod and the fixed seat, which is not shown in the figure.

[0022] A process for installing a tail plug for a glass glue bottle comprises placing a tail plug 2 into a bottle body 1, and then using a force measuring device to measure and record the force applied to the tail plug 2 when it moves at a sealing section position and / or different positions in the bottle body 1, and comparing the measured force with corresponding parameters of qualified products to determine whether the product is qualified.

[0023] The combination method of the tail plug 2 and the bottle body 1 is: select the smallest inner diameter bottle body 1, the largest inner diameter bottle body 1, the largest outer diameter tail plug 2, and the smallest outer diameter tail plug 2 from the bottle bodies 1 and tail plugs 2 processed for the first time in each shift, and then test the smallest inner diameter bottle body 1 and the largest outer diameter tail plug 2 together, and test the largest inner diameter bottle body 1 and the smallest outer diameter tail plug 2 together; if the corresponding parameters of the inspected product do not meet the corresponding parameters of the qualified product, find out the molds corresponding to the relevant bottle body 1 and tail plug 2, stop using them first, and then test them in the above manner. If they meet the requirements, they can be produced and assembled first to avoid a complete shutdown.

[0024] The outer diameter of the tail plug 2 is measured at its bottom, or by measuring the outer diameters at both ends of the tail plug 2 and taking the average value as the measured outer diameter of the tail plug 2, or by screening the tail plug 2 with the largest and smallest outer diameters through a copper sleeve of a fixed size. The inner diameter of the bottle body 1 is measured at its bottom; or by measuring the inner diameters at both ends of the inner cavity of the bottle body 1 and taking the average value as the measured inner diameter of the bottle body 1; or by screening the bottle body 1 with the largest and smallest inner diameters through a copper rod of a fixed size.

[0025] The force measuring device is a tension or pressure testing device, which puts the tail plug 2 into the tail of the bottle body 1, pulls or pushes the tail plug 2 to move toward the head of the bottle body 1, and records the static friction overcome by the tail plug 2 when it moves from static to moving, and judges the sealing between the tail plug 2 and the bottle body 1 by the static friction; in addition, the change of dynamic friction during the movement of the tail plug 2 from the tail of the bottle body 1 to the head of the bottle body 1 is recorded to judge the feel of the glass glue bottle when it is used; and the change of dynamic friction is recorded in the form of a curve for monitoring and control. Taking the pressure testing device as an example, the selected tail plug 2 is inserted into the tail of the bottle body 1, and this position is the sealing position; after the bottle body 1 of the glass glue bottle is inverted, the lower end of the bottle body is connected to the fixing seat 31, and the lower end of the push rod 7 is connected to the tail plug 2, and then a control command is given to the electric telescopic rod to gradually shorten it. Therefore, the push rod 7 generates pressure on the tail plug 2 until the tail plug 2 just starts to move, and the static friction force of the sealing position between the tail plug 2 and the bottle body 1 can be obtained; by comparing the static friction force with the corresponding parameters of qualified products, if it falls within the normal range, the sealing is passed.

[0026] Continue to start the electric telescopic rod to retract, and the tail plug 2 moves toward the inner end of the bottle body 1. The force changes during the movement are counted by the computer and a force curve is generated. This curve can be compared with the corresponding parameters of qualified products to determine whether the feel of the product is qualified during actual application.
