Description

Technical Field

[0001] The utility model relates to the technical field of glass tube production, in particular to an observation device for detecting defects in glass tubes. Background Art

[0002] When using the Dynaudio process to produce pharmaceutical glass tubes, specific defects such as streaks can occur due to uneven glass homogenization and temperature differences during molding. These defects cannot be detected by the continuous defect detectors on the production line. The only way to determine the number and type of defects is by observing the shadow of the glass tube under strong light. In practice, workers use one hand to steady the glass tube while using a strong flashlight with the other hand to illuminate the shadow, allowing them to detect defects in the shadow. This method can lead to errors in defect detection due to differences between operators and the angles of the hands holding the glass tube and the flashlight. Furthermore, this observation method is not conducive to single-person observation and recording.

[0003] The existing method for observing defects in glass tubes has technical problems such as angle differences caused by manual operation, which leads to inaccurate defect judgment and is not easy for a single person to observe and record. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0035] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0036] The existing method for observing defects in glass tubes has technical problems such as angle differences caused by manual operation, which leads to inaccurate defect judgment and is not easy for a single person to observe and record.

[0037] In view of this, the present invention provides an observation device for glass tube defect detection, comprising:

[0038] Observation box 100, lighting mechanism 200 and glass tube supporting mechanism 300. Glass tube supporting mechanism 300 is installed in observation box 100 for supporting glass tube 001, which is inserted into observation box 100. Lighting mechanism 200 is installed in observation box 100 for providing light to glass tube 001.

[0039] Based on the above technical solutions, the observation device provided by the present invention can achieve the following technical effects:

[0040] This observation device replaces the traditional manual grip and lighting with a fixed glass tube support mechanism 300 and an illumination mechanism 200. This standardizes the observation and lighting angles, avoiding errors caused by individual angle deviations during observation. This overcomes the technical problems of existing glass tube defect observation methods, where manual angle variations lead to inaccurate defect judgments and are difficult for a single person to observe and record.

[0041] The following combination Figures 1 to 5The structure and shape of the observation device provided in this embodiment are described in detail:

[0042] In the solution of this embodiment, Figure 2 As shown, the observation box 100 comprises a carrying case 110 and a portable cover 120, which is hingedly connected to the carrying case 110. The portable cover 120 is provided with a carrying handle 102 to facilitate rotation of the portable cover 120 relative to the hinge 130. The enclosed observation box 100 is designed to block external interfering light. The portable cover 120 has a viewing window 103, through which an operator can observe the projection of light from the lighting mechanism 200 through the glass tube 001 onto the inner wall of the observation box 100.

[0043] Regarding the structural composition of the lighting mechanism 200, specifically:

[0044] like Figure 4 As shown, the lighting mechanism 200 includes a lighting assembly 210. The lighting assembly 210 includes a halogen lamp 211 and a lamp holder 212. The halogen lamp 211 is mounted on the lamp holder 212 and is used to illuminate the glass tube 001, so that defects in the glass tube 001 are projected onto the inner wall of the observation box 100, thereby being visually observed by the operator.

[0045] In order to improve the lighting effect of the halogen lamp 211, in the solution of this embodiment, as shown in FIG. Figure 4 As shown, the lighting assembly 210 further includes a lampshade 213, which is mounted on the halogen lamp 211. The lampshade 213 defines a light channel 201, which is used to control the direction of light emitted by the halogen lamp 211. The inner wall of the lampshade 213 is coated with a reflective material to focus the light emitted by the halogen lamp 211 through the light channel 201.

[0046] In the preferred embodiment of the present invention, the lighting assembly 210 further includes a voltage regulator, and the halogen lamp 211 is connected to the power supply via the voltage regulator. The staff can adjust the brightness of the halogen lamp 211 by adjusting the switch on the voltage regulator, thereby being able to more comprehensively observe the defects of the glass tubes 001 of different specifications and models.

[0047] In order to facilitate the adjustment of the illumination of the halogen lamp 211 on the glass tube 001, in the solution of this embodiment, as shown in FIG. Figure 4 As shown, the lighting mechanism 200 further includes a moving assembly 220, which includes a screw 221 and a slide 222. The screw 221 is rotatably connected to the carrying case 110. The screw 221 is inserted into the slide 222, and the lamp holder 212 is mounted on the slide 222. The rotation of the screw 221 drives the halogen lamp 211 to move along the length of the screw 221, thereby adjusting the illumination position to facilitate more comprehensive observation of defects in the glass tube 001.

[0048] In order to improve the movement stability of the slide 222, in the solution of this embodiment, as shown in FIG. Figure 4 As shown, the moving assembly 220 further includes a guide rail 223 and a bearing seat 224. The guide rail 223 is arranged parallel to the screw rod 221, and the slide 222 is slidably connected to the guide rail 223. The two ends of the screw rod 221 are respectively provided with a bearing seat 224 installed on the carrying box 110.

[0049] In order to facilitate the operator to operate the screw 221, in the solution of this embodiment, as shown in FIG. Figure 4 As shown, the moving assembly 220 further includes a hand wheel 225, which is mounted on the screw rod 221. The rotation of the hand wheel 225 is used to drive the screw rod 221 to adjust the position of the halogen lamp 211.

[0050] Regarding the structural composition of the glass tube supporting mechanism 300, specifically:

[0051] like Figure 5 As shown, the glass tube carrying mechanism 300 includes a slide rail 310 and a slider 320. The slide rail 310 is mounted on the carrying box 110. The slider 320 is slidably connected to the slide rail 310 in a direction perpendicular to the length of the screw 221. The slider 320 includes a support frame 321, which is provided with a positioning groove for positioning the glass tube 001. The sliding of the slider 320 along the slide rail 310 is used to change the illumination angle of the halogen lamp 211 on the glass tube 001, thereby facilitating a more comprehensive observation of defects in the glass tube 001. The positioning groove can be configured as an outer semicircular groove.

[0052] In the solution of this embodiment, Figure 2 As shown, the observation box 100 is provided with a straight groove 101, and the glass tube 001 is inserted into the straight groove 101. The straight groove 101 extends along the length direction of the slide rail 310, and is used to avoid the movement of the glass tube 001 driven by the slider 320. The carrying box 110 is provided with a first half groove 111, and the portable cover 120 is provided with a second half groove 121. When the carrying box 110 and the portable cover 120 are closed, the first half groove 111 and the second half groove 121 form the straight groove 101. The rotation of the portable cover 120 around the carrying box 110 is used to switch the closed state of the straight groove 101, so as to facilitate the placement of the glass tube 001. When the carrying box 110 and the portable cover 120 are unfolded, the glass tube 001 can be placed between the first half groove 111 and the second half groove 121.

[0053] In summary, the specific working process of the observation device provided in this embodiment is as follows:

[0054] Take the glass tube 001 and the screw 221 as an example.

[0055] The glass tube support mechanism 300 and the lighting mechanism 200 are mounted on the observation box 100. The portable lid 120 is flipped over to unfold the observation box 100. The ends of the glass tube 001 are placed on the support frame 321, between the first half-trough 111 and the second half-trough 121. The portable lid 120 is flipped over to close the observation box 100, blocking any external interference light.

[0056] Halogen lamp 211 is turned on. Its beam passes through glass tube 001 and is projected onto the inner wall of observation box 100. The voltage regulator is adjusted to select the appropriate brightness to match the model of glass tube 001. The operator observes the projection on the inner wall of observation box 100 through window 103 to determine any defects in glass tube 001.

[0057] The operator slides the slider 320 to change the irradiation angle of the halogen lamp 211 on the glass tube 001 , so as to more comprehensively observe the defects of the glass tube 001 .

[0058] The operator rotates the hand wheel 225 to drive the screw 221 to drive the halogen lamp 211 to slide along the length direction of the glass tube 001, so as to more comprehensively observe the defects of the glass tube 001.
