It should be noted that, in the present utility model, before performing the breaking detection, the operator may preset the preset pressure, and according to the strength of the glass 6 to be detected, different preset pressures may be specifically set to detect various types of glass, thereby expanding the applicability of the apparatus.

Therefore, the glass detection device designed by the utility model adopts the lifting driving piece to stably apply force, the pressing force of the pressing head 23 on the glass 6 to be detected is uniform, the glass can be prevented from being damaged carelessly during manual operation, the labor is not required, the working efficiency can be greatly improved, and the glass detection device has good popularization prospect and application value.

Further, the lifting driving member includes a first cylinder 21 and a pressing rod 22, the first cylinder 21 is disposed on the main frame 1 and is connected to the pressing rod 22, and one end of the pressing rod 22 away from the first cylinder 21 is connected to the pressing head 23, so that the pressing rod 22 drives the pressing head 23 to approach or separate from the glass 6 to be detected under the action of the first cylinder 21.

In the utility model, the designed lifting driving piece can specifically comprise a first air cylinder 21 and a pressing rod 22, so that the pressing rod 22 can effectively drive a pressing head 23 to vertically press against the glass 6 to be detected under the action of the first air cylinder 21.

Further, the positioning assembly 3 further includes a vacuum chuck 31, and the vacuum chuck 31 is disposed on the main frame 1 to adsorb the glass 6 to be measured.

In the utility model, in order to ensure that the glass 6 to be detected can be firmly positioned and fixed by the positioning component 3, a vacuum chuck 31 can be specifically arranged in the positioning component 3, and the designed vacuum chuck 31 can be specifically arranged on the main frame 1 and can effectively adsorb and fix the glass 6 to be detected.

Of course, in some other embodiments, the operator may also set two or more vacuum chucks 31 as desired for better performance. It should be noted that, in the present utility model, the technical effect that the vacuum chuck 31 is used to adsorb the glass 6 to be detected by vacuumizing is known in the prior art, and the working principle of the vacuum chuck 31 is not repeated here.

Further, the positioning assembly 3 further includes at least two positioning rods 32, the positioning rods 32 are disposed on the main frame 1, and two adjacent edges of the glass 6 to be detected can respectively abut against the corresponding positioning rods 32.

In the present utility model, as shown in fig. 1, the glass 6 to be inspected is placed horizontally and sucked by two vacuum chucks 31. In order to facilitate the operator to set the glass 6 to be detected at the detecting station in the horizontal direction, the inventor further designs three positioning rods 32, wherein the three positioning rods 32 are fixedly arranged on the main frame 1, and two adjacent edges of the glass 6 to be detected can respectively abut against the corresponding positioning rods 32, so that the two directions of the glass 6 to be detected in the horizontal direction are limited by the three positioning rods 32.

Referring to fig. 1, it can be seen that, during actual operation, an operator only needs to control two adjacent edges of the glass 6 to be detected to be tightly attached to three positioning rods 32, so as to utilize the three positioning rods 32 to realize positioning in the horizontal direction, and then apply the vacuum chuck 31 to adsorb the glass 6 to be detected, so that the glass 6 to be detected can be rapidly positioned.

It should be noted that in certain preferred embodiments, the fixed positions of the positioning rods 32 and the main frame 1 are adjustable in specific designs, so that an operator can adjust the fixed positions of the positioning rods 32 in real time, thereby adapting to the detection requirements of different glasses.

For example, in the embodiment shown in fig. 1, a waist-shaped hole 321 is further formed at one end of the positioning rod 32 fixedly connected to the main frame 1, and a positioning hole is formed in the main frame 1, and the positioning rod 32 and the main frame 1 can be fixedly connected by sequentially passing through the waist-shaped hole 321 (as shown in fig. 2) and the positioning hole by using a bolt.

Therefore, when an operator controls the side positioning rod 32 of the glass 6 to be detected to be close, the edge of the glass 6 to be detected is contacted with the circumferential side wall of the positioning wheel 32; through such arrangement, when the operator controls the edge of the glass 6 to be detected to be tightly attached to the circumferential side wall of the positioning wheel 32 for displacement, the movement of the glass 6 to be detected also drives the positioning wheel 32 to rotate compared with the axis of the positioning rod 32.

Further, the positioning wheel 33 is a nylon wheel.

In the present utility model, since the outer contour of the positioning wheel 33 will contact with the glass 6 to be inspected, in order to prevent the positioning wheel 32 from scratching the glass 6 to be inspected, the positioning wheel 33 may be specifically selected from wheels made of POM materials, for example: nylon wheels made from hard nylon materials.

It should be noted that, in some other preferred embodiments, the second air cylinder 35 may not be provided, and the effect of pressing and fixing the glass 6 to be detected by the pressing member 34 may also be achieved by providing an elastic member capable of elastically deforming in the pressing member 34 and utilizing the elastic force generated by the elastic member due to its elastic deformation.

Further, the compressing assembly 2 is provided with a positioning hole, and the top of the main frame 1 is provided with at least two mounting holes which can be matched with the positioning hole; when the positioning holes are opposite to different mounting holes, the pressure head 23 is abutted against different positions of the glass 6 to be detected.

Further, the device also comprises a pulley 5, wherein the pulley 5 is fixedly arranged at the bottom of the main support 1, and a locking mechanism 51 is arranged on the pulley 5.

In such a glass inspection device designed in the present utility model, in order to facilitate the movement of the glass inspection device by an operator, the inventor further fixedly installs a pulley 5 at the bottom of the main support 1. When in actual use, an operator only needs to apply external force to the main support 1, and the pulley 5 can be utilized to realize the sliding of the main support 1, so that the use of the operator is greatly facilitated.

Correspondingly, after the glass detection device moves to a proper position, in order to quickly and conveniently control the glass detection device to stop sliding, a locking mechanism 51 is further arranged on the pulley, and after the glass detection device moves in place, an operator steps on the locking mechanism 51 to prevent the pulley 5 from continuing to rotate and prevent the main support 1 from moving.

In addition, in the glass inspection device designed according to the present utility model, in order to enhance the steering performance of the pulley 5, the pulley 5 provided at the bottom of the main frame 1 may be specifically selected as a universal wheel.

Example 1

Referring to fig. 1-2, a first embodiment of the present utility model is as follows: a glass detection device, comprising: a main frame 1, a pressing assembly 2, a positioning assembly 3 and four pulleys 5. In this embodiment, the main body frame 1 is a rectangular parallelepiped frame, the bottom profile of the main body frame 1 is rectangular, and the four pulleys 5 are fixedly disposed at the bottom of the main body frame 1 and are disposed at four corners of the rectangle, respectively.

In this embodiment, all four pulleys 5 are universal wheels, and locking mechanisms 51 are arranged on the universal wheels. When in actual use, an operator can slide the main bracket 1 by utilizing the pulley 5 only by applying external force to the main bracket 1; when the glass detecting device is moved to a proper position, an operator can prevent the pulley 5 from continuing to rotate by pressing the locking mechanism 51, and further movement of the main bracket 1 is prevented.

As shown in fig. 1, in the present embodiment, the pressing assembly 2 specifically includes: a first cylinder 21, a compression bar 22 and a ram 23. The first cylinder 21 is fixedly arranged on the main frame 1 and is connected with a compression bar 22, and one end part of the compression bar 22 far away from the first cylinder 21 is connected with a pressure head 23, so that the compression bar 22 can drive the pressure head 23 to be close to or far away from the first cylinder 21 under the action of the first cylinder 21. In the present embodiment, the pressing rod 22 and the pressing head 23 move up and down specifically in the vertical direction by the first cylinder 21.

Accordingly, in this embodiment, the positioning assembly 3 specifically includes: two vacuum chucks 31, three positioning rods 32, two hold-down members 34, and two second cylinders 35. Wherein, the two vacuum chucks 31 are used for adsorbing the glass 6 to be detected, the three positioning rods 32 are used for positioning the glass 6 to be detected in two directions in the horizontal direction, and the two pressing pieces 34 are used for pressing the glass 6 to be detected.

It should be noted that, in the present embodiment, two vacuum chucks 31 are designed to be disposed on the main frame 1 along the moving direction (i.e., the vertical direction) of the pressing rod 22, and the glass 6 to be detected is sucked by the two vacuum chucks 31, so that the glass 6 to be detected is perpendicular to the moving direction of the pressing rod 22 (i.e., the glass 6 to be detected is placed horizontally). In order to facilitate the operator to set the glass 6 to be detected at the detecting station in the horizontal direction, the inventor also designs three positioning rods 32, wherein the three positioning rods 32 are fixedly arranged on the main frame 1, and two adjacent edge parts of the glass 6 to be detected can respectively lean against the corresponding positioning rods 32, so that two directions of the glass 6 to be detected in the horizontal direction are limited by the three positioning rods 32.

Referring to fig. 1, it can be seen that two positioning rods 32 are provided along the length direction of the glass 6 to be detected, one positioning rod 32 is provided along the width direction of the glass 6 to be detected, and an operator can realize positioning in the horizontal direction by only controlling two adjacent edges of the glass 6 to be detected to be closely attached to the three positioning rods 32 during actual operation. In this embodiment, the end of the positioning rod 32 fixedly connected to the main frame 1 is further provided with a waist-shaped hole 321 (as shown in fig. 2), and the main frame 1 is provided with a positioning hole, which sequentially passes through the waist-shaped hole 321 and the positioning hole by using a bolt, so that the fixed connection between the positioning rod 32 and the main frame 1 can be realized. Based on this arrangement, the operator can adjust the fixing position of the positioning rod 32 on the main frame 1, i.e. the operator can unscrew the bolts properly, and at this time, since the hole pattern of the waist-shaped hole 321 of the positioning rod 32 is strip-shaped, it can move compared with the positioning hole, so as to adjust the fixing position of the positioning rod 32 properly, and adapt to the detection requirements of different glasses. After the adjustment is completed, the fixing and positioning of the positioning rod 32 and the main frame 1 can be realized again only by tightening the bolts.

Furthermore, in the present embodiment, a positioning wheel 33 is provided at one end of the positioning rod 32 near the glass 6 to be inspected, and a bearing is provided between the positioning wheel 33 and the positioning rod 32 to realize rotatable connection between the positioning wheel 33 and the positioning rod 32. Since the circumferential side wall of the positioning wheel 33 will contact with the glass 6 to be detected, in order to prevent the positioning wheel 32 from scratching the glass 6 to be detected, the positioning wheel 33 is specifically made of nylon wheel made of hard nylon material. Therefore, when an operator controls the side positioning rod 32 of the glass 6 to be detected to be close, the edge of the glass 6 to be detected is contacted with the circumferential side wall of the positioning wheel 32; through the arrangement, when an operator controls the edge of the glass 6 to be detected to be closely attached to the outer contour of the positioning wheel 32 for displacement, the movement of the glass 6 to be detected also drives the positioning wheel 32 to rotate compared with the axis of the positioning rod 32.

In addition, in the present embodiment, in order to further enhance the fixing and positioning effect of the glass 6 to be detected, two pressing members 34 and two second cylinders 35 are further provided in the positioning assembly 3. The two second cylinders 35 are fixedly arranged on the main support 1, and each second cylinder 35 is correspondingly connected with a pressing piece 34, so that the pressing pieces 34 can press the glass 6 to be detected under the action of the second cylinders 35.

Accordingly, as can be seen with further reference to fig. 1, in this embodiment, in order to support the glass 6 to be inspected, a support rod 4 is further provided on the main support 1, and one end of the support rod 4 can be fixedly connected to the main support 1. The other end of the device can be contacted with the lower surface of the glass 6 to be detected so as to support the glass 6 to be detected at the detection station, thereby ensuring the normal operation of the subsequent detection process.

In the practical application process, an operator only needs to control two adjacent edges of the glass 6 to be detected to be tightly attached to the three positioning rods 32, so that the three positioning rods 32 are utilized to realize the positioning of the glass 6 to be detected in the horizontal direction, and then the vacuum chuck 31 is utilized to adsorb the glass 6 to be detected, so that the glass 6 to be detected can be rapidly positioned. At this time, the lower surface of the glass 6 to be detected is contacted with the supporting rod 4, and an operator can drive the two pressing blocks 34 to be pressed against the upper surface of the glass 6 to be detected from top to bottom by controlling the two second air cylinders 35, so that the glass 6 to be detected is pressed and fixed. After the fixed positioning of the glass 6 to be detected is finished, the first air cylinder 21 in the pressing assembly 2 is controlled to be opened, so that the pressing rod 22 can drive the pressing head 23 to vertically press the glass 6 to be detected which is placed horizontally under the action of the first air cylinder 21 to detect whether the glass 6 to be detected has a crack risk: if the glass 6 to be detected has cracks, the glass 6 to be detected has a cracking condition, and if the glass 6 to be detected has no cracks, the glass 6 to be detected has no cracking condition.

Therefore, the glass detection device designed by the utility model adopts the first air cylinder 21 to stably apply force, the pressing force of the pressing head 23 on the glass 6 to be detected is uniform, the glass can be prevented from being damaged carelessly during manual operation, the labor is not required, the working efficiency can be greatly improved, and the glass detection device has good popularization prospect and application value.
