Description

Technical Field

[0001] This utility model mainly relates to the technical field of thermal break aluminum strip insertion, specifically a thermal break aluminum strip clamping detection system. Background Technology

[0002] The main processing method for thermally broken aluminum profiles is the strip-insertion method. This method connects two parts of the aluminum profile using thermally insulating strips to achieve insulation. In existing technology, the strip-insertion process for thermally broken aluminum profiles can be achieved through the following steps: First, at station A, profile A is toothed, and then two rubber strips are inserted onto side A. The profile A with the two rubber strips is then transported to station B. After profile B is toothed, it is inserted onto the two rubber strips on profile A to achieve side B strip insertion, thus connecting profile A and profile B as a single unit with two thermally insulating strips in the middle.

[0003] The aforementioned existing technology has the following technical problems: When threading the strip at station B, it is generally detected whether the strip has moved to the appropriate position to facilitate automated operation. However, since there are two strips, in special cases, one of the strips may not be threaded properly. In this case, when clamping the strip at station B, even if only one strip is clamped properly, the strip positioning signal will still be triggered. When threading the strip on side B, this will result in only one strip being threaded properly while the other strip is not. If the system cannot detect this, defective products will flow into subsequent processes, affecting the efficient production of thermally broken aluminum. Utility Model Content

[0004] To address the shortcomings of current technology, this utility model, combining existing technology and based on practical application, provides a thermal break aluminum strip insertion and clamping detection system. This system, during the insertion of thermal break aluminum strips, can not only detect whether the strips are properly positioned, but also whether both strips are properly clamped, ensuring a high strip insertion pass rate and preventing defective products from entering subsequent production lines.

[0005] The technical solution of this utility model is as follows: A thermal break aluminum alloy strip clamping detection system includes: The adhesive strip placement detection unit is configured to detect whether the adhesive strip is in place when the thermal break aluminum strip is inserted. The first adhesive strip clamping unit is configured to clamp and fix the first adhesive strip. The second adhesive strip clamping unit is configured to clamp and fix the second adhesive strip. The first adhesive strip clamping detection unit is configured to detect whether the first adhesive strip clamping unit is clamped in place. The second adhesive strip clamping detection unit is configured to detect whether the second adhesive strip clamping unit is clamped in place.

[0006] Furthermore, the adhesive strip positioning detection unit uses a through-beam photoelectric sensor.

[0007] Furthermore, the transmitting end of the through-beam photoelectric sensor is located behind the first adhesive strip clamping unit, and the receiving end of the through-beam photoelectric sensor is located behind the second adhesive strip clamping unit.

[0008] Furthermore, the first adhesive strip clamping unit and the second adhesive strip clamping unit are arranged opposite to each other. Both the first adhesive strip clamping unit and the second adhesive strip clamping unit include an adhesive strip clamping movable part and an adhesive strip clamping fixed part. The first adhesive strip clamping detection unit and the second adhesive strip clamping detection unit detect whether the adhesive strip is clamped in place based on the position of the adhesive strip clamping movable part.

[0009] Furthermore, the adhesive strip clamping movable parts of the first adhesive strip clamping unit and the second adhesive strip clamping unit are each controlled by an adhesive strip clamping cylinder, and the first adhesive strip clamping detection unit and the second adhesive strip clamping detection unit are respectively installed on the corresponding adhesive strip clamping cylinder.

[0010] Furthermore, both the first adhesive strip clamping detection unit and the second adhesive strip clamping detection unit are magnetic switches. The position of the adhesive strip clamping movable part is determined by detecting the position of the cylinder rod, thereby detecting whether the adhesive strip is clamped in place.

[0011] Furthermore, the adhesive strip clamping movable part is provided with serrations.

[0012] Furthermore, the first adhesive strip clamping unit and the second adhesive strip clamping unit are respectively mounted on the lifting assembly, and the height of the first adhesive strip clamping unit and the second adhesive strip clamping unit can be adjusted by the lifting assembly.

[0013] The beneficial effects of this utility model are: 1. In this utility model, the adhesive strip arrival detection unit can detect whether the adhesive strip has entered the threading position, so as to realize the automated threading operation. At the same time, the first adhesive strip clamping detection unit and the second adhesive strip clamping detection unit can respectively detect whether the two adhesive strips are clamped in place. If the clamping is not in place, the control system issues an alarm signal and stops the machine. If both are clamped in place, the system automatically threads the strip. Through multi-directional automatic detection, this system ensures that both adhesive strips are in place during threading, thus preventing unqualified products from flowing into the subsequent production line.

[0014] 2. In this utility model, a through-beam sensor is used to detect whether the adhesive strip has moved to the clamping position, and a magnetic switch is used in conjunction with a cylinder to detect whether both adhesive strips are clamped in place. It has the advantages of simple overall structure, easy implementation and high stability. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] This embodiment provides a strip insertion and clamping detection system for thermally broken aluminum profiles. During the strip insertion process, after the strip insertion on side A is completed, profile A with two adhesive strips moves to the strip insertion station on side B for profile B insertion. During the strip insertion process of profile B, the adhesive strips need to be clamped and fixed to allow profile B to move and complete the insertion operation. Therefore, whether the adhesive strips are clamped properly directly affects whether profile B is successfully inserted. The detection system in this embodiment detects whether each action during the strip insertion and clamping process is performed correctly to ensure the yield rate.

[0020] refer to Figure 1 as well as Figure 2 As shown in the figure. The thermal break aluminum strip insertion and clamping detection system provided in this embodiment includes: a strip arrival detection unit 1, which is configured to detect whether the strip 2 is in place when inserting the thermal break aluminum strip. The strip arrival detection unit 1 mainly detects whether the strip 2 has moved to the clamping position when the profile moves to station B, at which position the strip can be inserted smoothly. Through the output signal of the strip arrival detection unit 1, the control system determines that the strip 2 has moved to the correct position, and then activates the clamping structure to clamp and fix the strip 2, after which the strip insertion operation can be performed.

[0021] In one specific embodiment provided in this example, the adhesive strip positioning detection unit 1 is implemented using a through-beam photoelectric sensor. (See reference...) Figure 2As shown, the transmitting end 11 of the through-beam photoelectric sensor is located behind the first adhesive strip clamping unit 3, and the receiving end 12 of the through-beam photoelectric sensor is located behind the second adhesive strip clamping unit 4. A light beam is formed between the transmitting end 11 and the receiving end 12 of the through-beam photoelectric sensor. When the adhesive strip 2 moves into position and touches the light beam, the adhesive strip position detection unit generates a signal to determine whether the adhesive strip 2 has moved into position. It can be seen that in special cases, even when only one adhesive strip is in position, the adhesive strip position detection unit 1 can still be triggered to generate a signal. In this case, the strip insertion will produce defective products. Therefore, this embodiment also provides a clamping detection structure to ensure the yield of the inserted strip.

[0022] The first adhesive strip clamping unit 3 and the second adhesive strip clamping unit 4 are structurally identical and are respectively used to clamp and fix the adhesive strips 2 on the left and right sides. In a specific embodiment provided in this example, refer to... Figure 2 As shown, the first adhesive strip clamping unit 3 and the second adhesive strip clamping unit 4 are respectively fixed to a lifting plate 13. The lifting plate 13 is connected to a lifting motor 14 through a screw-slider structure. The lifting motor 14 can control the height of the first adhesive strip clamping unit 3 and the second adhesive strip clamping unit 4 so that the strip-threading structure can be adapted to profiles of different shapes. The specific structure of the first adhesive strip clamping unit 3 and the second adhesive strip clamping unit 4 is as follows: each includes an adhesive strip clamping cylinder 9. An adhesive strip clamping movable part 7 is connected to the cylinder rod of the adhesive strip clamping cylinder 9. An adhesive strip clamping fixed part 8 is provided on one side of the adhesive strip clamping movable part 7. The adhesive strip clamping fixed part 8 is fixed on the lifting plate 13. When the adhesive strip clamping cylinder 9 is activated, it pushes the adhesive strip clamping movable part 7 to move relative to the adhesive strip clamping fixed part 8, thereby realizing the clamping and release of the adhesive strip 2. Furthermore, in order to ensure the clamping effect, one side of the adhesive strip clamping fixed part 7 is set in a serrated shape.

[0023] The first adhesive strip clamping detection unit 5 and the second adhesive strip detection unit 6 are used to detect whether the first adhesive strip clamping unit 3 and the second adhesive strip clamping unit 4 are clamped in place. As mentioned above, the adhesive strip placement detection unit 1 alone cannot determine whether both adhesive strips are fully in place when threading the strip. Therefore, in this embodiment, a first adhesive strip clamping detection unit 5 and a second adhesive strip detection unit 6 are provided to detect the clamping of the two adhesive strips 2. Specifically, both the first adhesive strip clamping detection unit 5 and the second adhesive strip detection unit 6 use a magnetic switch 10, which is installed at a suitable position in the adhesive strip clamping cylinder 9. The magnetic switch 10 can detect the position of the cylinder rod inside the adhesive strip clamping cylinder 9, thereby realizing the signal output. That is, when the adhesive strip clamping movable part 7 and the adhesive strip clamping fixed part 8 cooperate to clamp the adhesive strip 2, the cylinder rod just moves to the position to trigger the magnetic switch 10. If the clamping is not in place, the magnetic switch 10 signal is not triggered. Therefore, the two magnetic switches 10 can detect whether the two adhesive strips are properly clamped. The control system performs the strip insertion operation based on the signals from the magnetic switches 10, provided that both strips are properly clamped. If either strip is not properly clamped, the machine stops and an alarm sounds. Thus, through the multi-directional detection in this embodiment, the problem of failed strip insertion of the thermally broken aluminum due to improper clamping, which still leads to the next process, can be avoided.
