[0005] The bathroom glass caulking and assembly machine according to the embodiments of this utility model has at least the following technical effects: Since each profile has a groove, but the shape of the side of the profile away from the upper opening is different, the way different profiles are placed on the conveying device is also different. This utility model sets two support seats that can move closer and further apart and can move up and down. Rotatable snap-fit ​​parts are set on the support seats. When the conveying device conveys the profile between the two snap-fit ​​parts, the two support seats can move closer and closer to each other, so that the two snap-fit ​​parts can snap-fit ​​and connect with the left and right sides of different profiles. After the two support seats move upward, the two snap-fit ​​parts can drive the profile to rotate when they rotate, ensuring that the upper opening of the groove of different profiles faces upward, ensuring that the glue application device can apply glue to the groove, realizing that the bathroom glass caulking and assembly machine can apply glue to the groove of different profiles, thus improving the applicability of the bathroom glass caulking and assembly machine.

[0006] Furthermore, one of the clamping assemblies further includes a positioning seat, which is movably mounted vertically on the right side of the conveying device, and the support seat of one of the clamping assemblies is movably mounted horizontally on the positioning seat;

[0007] The support base of another clamping assembly is movable up and down and mounted on the left side of the conveying device.

The first driving device is used to rotate the mounting base.

[0009] Furthermore, the clamping assembly also includes a second driving device, which is mounted on the mounting base and connected to the snap-fit ​​component. The second driving device is used to drive the snap-fit ​​component to move left and right.

[0010] Furthermore, the portion of the snap-fit ​​component that abuts against the slot is arc-shaped.

[0011] Furthermore, the conveying device includes a motor, a connecting shaft, and two conveying components. The two conveying components are arranged at intervals in the left-right direction. Each conveying component includes a belt, a drive pulley, and a driven pulley. The outer side wall of the belt is provided with a plurality of push bars arranged at intervals in front and behind.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figure 1 , 2 As shown in Figure 3, the bathroom glass caulking and assembly machine according to an embodiment of the present invention includes a caulking mechanism 100. The caulking mechanism 100 includes a conveying device 110, a clamping device 120, and an adhesive applicator 130. The conveying device 110 is used to convey the profile 200 back and forth. The clamping device 120 includes two clamping components 121, which are located on the left and right sides of the conveying device 110, respectively. Each clamping component 121 includes a support base 122 and a snap-fit ​​component 123. The two support bases 122 can move closer to each other and further away from each other and can move up and down. The snap-fit ​​component 123 is rotatably mounted on the support base 122. When the two support bases 122 are close to each other, the two snap-fit ​​components 123 can snap into the left and right sides of the groove 210 of the profile 200, respectively. The adhesive applicator 130 is located above the clamping device 120 and can apply adhesive to the groove 210.

[0034] like Figure 3As shown, since each profile 200 has a slot 210, but the shape of the side of the profile 200 away from the upper opening 220 is different, the way different profiles 200 are placed on the conveying device 110 is also different. This utility model provides two support seats 122 that can move closer and further apart and can move up and down, and provides rotatable snap-fit ​​parts 123 on the support seats 122, such as... Figure 1 , 2 As shown, when the conveying device 110 conveys the profile 200 between the two snap-fit ​​pieces 123, the two support seats 122 can move closer to each other, so that the two snap-fit ​​pieces 123 can snap-fit ​​and connect with the left and right sides of different profiles 200. After the two support seats 122 move upward, the two snap-fit ​​pieces 123 can drive the profile 200 to rotate when they rotate, ensuring that the upper opening 220 of the groove 210 of different profiles 200 faces upward, ensuring that the glue application device 130 can apply glue to the groove 210, so that the bathroom glass glue application and assembly machine can apply glue to the groove 210 of different profiles 200, thereby improving the applicability of the bathroom glass glue application and assembly machine.

[0035] For example, the first type of profile: such as Figure 3 As shown, the side of profile 200 away from the upper opening 220 is a flat surface; the side of profile 200 away from the upper opening 220 can be directly placed on the conveying device 110, and the upper opening 220 of profile 200 can face directly upward. During operation, the two support seats 122 move closer to each other, causing the two snap fasteners 123 to also move closer to each other. The two snap fasteners 123 snap into the left opening 230 and the right opening respectively, clamping the profile 200. Then, the two support seats 122 drive the two snap fasteners 123 to move upward, causing the profile 200 to move upward. The glue applicator applies glue to the groove 210. After the glue application is completed, the two support seats 122 move downward, driving the two snap fasteners 123 to move downward, so that the profile 200 is placed on the conveying device 110. Then, the two support seats 122 move away from each other, and the conveying device 110 continues to convey the profile 200.

[0036] Second profile: The side of profile 200 away from the upper opening 220 is curved; due to the existence of the curved surface, the side of profile 200 away from the upper opening 220 cannot be placed on the conveying device 110, and only the upper sidewall of profile 200 can be placed on the conveying device 110, so that the upper opening 220 of profile 200 can face directly downwards; during operation, the two support seats 122 move closer to each other, causing the two locking pieces 123 to also move closer to each other, and the two locking pieces 123 respectively engage with the left opening 230 and the right opening 220. The two snap-fit ​​pieces 123 clamp the profile 200 together. Then, the two support bases 122 drive the two snap-fit ​​pieces 123 to move upward, which in turn moves the profile 200 upward. Then, the two snap-fit ​​pieces 123 rotate simultaneously, which rotates the profile 200 180° so that the upper opening 220 of the profile 200 faces upward. The glue applicator applies glue to the groove 210. After the glue application is completed, the profile 200 is placed on the conveying device 110, and the conveying device 110 continues to convey the profile 200.

[0037] Specifically, the two support seats 122 can move synchronously to move closer to each other and further away from each other, or one support seat 122 can move while the other support seat 122 remains stationary, thus moving closer to each other and further away from each other.

[0038] Specifically, taking the example where one support 122 is movable while the other support 122 is stationary:

[0039] like Figure 1 , 2 As shown in Figure 4, one of the clamping components 121 also includes a positioning seat 124, which is movably mounted on the right side of the conveying device 110. The support seat 122 of one of the clamping components 121 is movably mounted on the positioning seat 124.

[0040] The support 122 of another clamping assembly 121 is movable up and down and is mounted on the left side of the conveying device 110.

[0041] During operation, the profile 200 is conveyed between two snap-fit ​​pieces 123. The support 122 of one of the clamping components 121 moves to the left on the positioning seat 124, causing the snap-fit ​​piece 123 on the right to move to the left and approach the snap-fit ​​piece 123 on the left. The two snap-fit ​​pieces 123 are respectively snap-fitted to the left opening 230 and the right opening of the profile 200, fixing the profile 200 between the two snap-fit ​​pieces 123. Then, the positioning seat 124 moves upward and the support 122 of the other clamping component 121 moves upward, thereby causing the two snap-fit ​​pieces 123 to drive the profile 200 to move upward. Depending on the needs of different profiles 200, it is selected whether to rotate the snap-fit ​​pieces 123.

[0042] Specifically, such as Figure 4As shown, one of the clamping components 121 also includes a third drive device 128 and a fourth drive device 129. The third drive device 128 is installed on the right side of the conveying device 110 and connected to the positioning seat 124. The third drive device 128 is used to drive the positioning seat 124 to move up and down. The support seat 122 of one of the clamping components 121 is movably installed on the positioning seat 124. The fourth drive device 129 is installed on the positioning seat 124 and connected to the support seat 122 of one of the clamping components 121. The fourth drive device 129 is used to drive the support seat 122 of one of the clamping components 121 to move left and right.

[0043] Another clamping assembly 121 also includes a fifth drive device (not shown in the figure), which is mounted on the left side of the conveying device 110 and is used to drive the support base 122 of the other clamping assembly 121 to move up and down.

[0044] During operation, when the profile 200 is conveyed between the two snap-fit ​​pieces 123, the fourth drive device 129 drives the support base 122 connected to it to move to the left, causing the snap-fit ​​piece 123 on the right to move to the left and approach the snap-fit ​​piece 123 on the left. The two snap-fit ​​pieces 123 are respectively snap-fitted to the left opening 230 and the right opening of the profile 200, fixing the profile 200 between the two snap-fit ​​pieces 123. Then, the third drive device 128 drives the positioning base 124 to move upward, and the positioning base 124 drives the support base 122 on the right to move upward. At the same time, the fifth drive device drives the support base 122 connected to it (the support base 122 on the left) to move upward, thereby driving the profile 200 to move upward. Then, depending on the needs of different profiles 200, it is selected whether to rotate the snap-fit ​​piece 123.

[0045] Specifically, the third drive unit 128, the fourth drive unit 129 and the fifth drive unit are all cylinders.

[0046] Specifically, the rotation of the snap-fit ​​component 123 can be driven manually, by a motor, or by other devices.

[0047] In a further embodiment of this utility model, such as Figure 4 As shown, the clamping assembly 121 further includes a mounting base 125 and a first driving device 126. The mounting base 125 is rotatably mounted on the support base 122, and the snap-fit ​​member 123 is mounted on the mounting base 125. The first driving device 126 is mounted on the support base 122 and connected to the mounting base 125. The first driving device 126 is used to rotate the mounting base 125.

[0048] The automation of the bathroom glass sealing and assembly machine is improved by setting a first drive device 126 to automatically drive the profile 200 to rotate.

[0049] When the profile 200 needs to be rotated, the first drive device 126 is activated, and the first drive device 126 drives the mounting base 125 to rotate, which in turn drives the snap-fit ​​component 123 to rotate.

[0050] Specifically, the first drive device 126 is a motor.

[0051] In a further embodiment of this utility model, such as Figure 4 As shown, the clamping assembly 121 further includes a second driving device 127, which is mounted on the mounting base 125 and connected to the snap-fit ​​member 123. The second driving device 127 is used to drive the snap-fit ​​member 123 to move left and right.

[0052] In addition to the fourth driving device 129 driving the snap-fit ​​component 123 to move left and right, a second driving device 127 is also provided to drive the snap-fit ​​component 123 to move left and right, so that the snap-fit ​​component 123 can move coarsely and finely respectively, to adapt to profiles 200 of different lengths, and to better control the snap-fit ​​force.

[0053] Specifically, the second drive unit 127 is a cylinder.

[0054] In some embodiments of this utility model, such as Figure 5 , 9 As shown in Figure 10, the portion 1231 of the snap-fit ​​component 123 that abuts against the slot 210 is arc-shaped, which facilitates the snap-fit ​​component 123 to be snapped and connected to the left opening 230 or the right opening.

[0055] In some embodiments of this utility model, such as Figure 6 As shown, the conveying device 110 includes a motor, a connecting shaft 111, and two conveying assemblies 112. The two conveying assemblies 112 are arranged at intervals in the left-right direction. Each conveying assembly 112 includes a belt 113, a drive wheel 114, and a driven wheel 115. The outer side wall of the belt 113 is provided with a plurality of push bars 116 arranged at intervals in the front and back. The drive wheels 114 of the two conveying assemblies 112 are connected together through the connecting shaft 111. The motor is connected to one of the drive wheels 114.

[0056] During operation, the worker places the profile 200 on the belt 113. The motor drives one of the drive wheels 114 to rotate. One drive wheel 114 drives the other drive wheel 114 to rotate through the connecting shaft 111. In turn, the two drive wheels 114 and the two driven wheels 115 drive the two belts 113 to move. The pusher 116 on the belt 113 drives the profile 200 to move backward.

[0057] In a further embodiment of this utility model, such as Figure 1, 6 As shown, it also includes a frame 300, a drive wheel 114 that is slidably connected to and can be fixed on the connecting shaft 111, and two conveying assemblies 112 that can be moved left and right on the frame 300 so that the conveying device 110 can adapt to profiles 200 of different lengths.

[0058] Specifically, the drive wheel 114 is keyed to the connecting shaft 111, and the drive wheel 114 is adjusted in position and then fixed in position by the key.

[0059] In a further embodiment of the present invention, the push bar 116 is detachably mounted on the belt 113, making it convenient to replace the push bar 116.

[0060] In some embodiments of this utility model, such as Figure 1 As shown, it also includes a crossbeam 400 located above the clamping device 120, and the glue device 130 includes a plurality of glue guns, which are mounted on the crossbeam 400 and can move up and down and left and right.

[0061] During operation, the glue gun moves downward and into the slot 210 to apply glue to the inside of the slot 210, and then moves left and right to apply glue to the entire slot 210.

[0062] When the glue applicator 130 includes multiple glue guns, the multiple glue guns can switch between each other to reduce glue replacement time.

[0063] Specifically, there are three glue guns, which are installed on the crossbeam 400 along the left and right directions.

[0064] Specifically, multiple glue-applying devices 130 can be provided, and the multiple glue-applying devices 130 are spaced apart in the left-right direction.

[0065] In some embodiments of this utility model, such as Figure 7 , 8 As shown, it also includes an assembly mechanism 500, which is located at the discharge end of the conveying device 110. The assembly mechanism 500 includes a support platform 510 and two push blocks 520 for placing the profile 200. The top of the support platform 510 has a roller assembly 530. The two push blocks 520 are movably mounted on the top of the support platform 510 and are located on the left and right sides of the roller assembly 530, respectively.

[0066] The assembly mechanism 500 facilitates the mounting of the profile 200 onto the glass.

[0067] During operation, the glass is placed on the roller assembly 530 and positioned between two push blocks 520. Each push block 520 is equipped with a profile 200. The user pushes the push block 520 to move closer to the glass, and the push block 520 then mounts the profile 200 onto the glass.
