Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] like Figure 1 and Figure 2 As shown, the patch equipment provided by the embodiment of the utility model includes a frame 1 and a feeding mechanism 2, a conveying mechanism 3 and a patch mechanism 4 arranged on the frame 1; the feeding mechanism 2 is used to convey the material belt; the conveying mechanism 3 includes a conveying component 31, a blocking component 32 and a positioning component 33; the conveying component 31 is arranged on the frame 1, and is used to horizontally convey the workpiece 7; the blocking component 32 is arranged on the conveying component 31, and is used to block or not block the workpiece 7; the positioning component 33 is arranged on the conveying component 31, and is used to fix the workpiece 7 on the conveying component 31; the patch mechanism 4 is used to drive the backing film on the material belt to move to the workpiece 7.

[0038] Among them, the adhesive backing sheet can be a sheet-like workpiece with adhesive adhered to the back side, such as a QR code, a label, a sponge, etc.

[0039] As an example, the operator loads the workpiece 7 onto the conveying component 31, and the conveying component 31 starts to convey the workpiece 7. When the workpiece 7 moves to abut against the blocking component 32, the conveying component 31 stops conveying the workpiece 7, and then the positioning component 33 positions the workpiece 7 so that the workpiece 7 is fixed on the conveying component 31; at the same time, the patch mechanism 4 moves to the feeding mechanism 2, takes away the back adhesive sheet on the material belt transported by the feeding mechanism 2, and drives the back adhesive sheet to move to the workpiece 7 on the conveying component 31, so as to attach the back adhesive sheet to the workpiece 7; then, the patch mechanism 4 moves to the feeding mechanism 2 again, To take the next backing film, at the same time, the blocking component 32 and the positioning component 33 are separated from the workpiece 7, and the conveying component 31 continues to convey the workpiece 7 to convey the workpiece 7 with the backing film attached to it to the next process, and convey the next workpiece 7 to a position opposite to the positioning component 33. The workpiece 7 abuts against the blocking component 32, and the conveying component 31 pauses conveying the workpiece 7, and then the positioning component 33 positions the workpiece 7 so that the workpiece 7 is fixed on the conveying component 31, and the mounting mechanism 4 attaches the backing film to the workpiece 7, and the above steps are repeated to realize the automatic mounting of the backing film on the workpiece 7.

[0040] In the patch equipment provided by the embodiment of the utility model, the patch mechanism 4 moves the backing film on the material belt transmitted by the feeding mechanism 2 to the workpiece 7 on the conveying component 31, so that the backing film is attached to the workpiece 7, and the backing film is automatically attached to the workpiece 7; at the same time, the blocking component 32 and the positioning component 33 cooperate to block and position the workpiece 7 on the conveying component 31, thereby preventing the workpiece 7 from moving during the patch process, ensuring the accuracy of the patch, and improving the pasting accuracy of the backing film. In addition, the blocking component 32 can also separate two adjacent workpieces 7 on the conveying component 31 to prevent the two adjacent workpieces 7 from colliding during the transmission process, thereby avoiding the occurrence of workpieces 7 with missing backing films, and improving the qualified rate of products.

[0041] In one embodiment, if Figure 3 As shown, the conveying assembly 31 includes two support seats 311 and two conveyor belt structures 312; the two support seats 311 are arranged on the frame 1 at a relative interval, and each support seat 311 is provided with a conveyor belt structure 312; the conveyor belt structure 312 includes a driving motor, a conveyor belt and two transmission rollers, the two transmission rollers are arranged on the support seats 311, the conveyor belt is wound around the two transmission rollers, the driving motor is connected to a transmission roller, and is used to drive the transmission roller to rotate, so as to drive the conveyor belt to run; the two conveyor belt structures 312 cooperate to synchronously transmit the workpiece 7.

[0042] In this example, the driving motor drives the transmission roller connected thereto to rotate, so that the transmission roller drives the conveyor belt to move, thereby driving another transmission roller to rotate, so that the conveyor belt circulates to transmit the workpiece 7. With this design, the workpiece 7 is transmitted synchronously by the cooperation of two conveyor belt structures 312, that is, the two conveyor belt structures 312 jointly support the workpiece 7, which reduces the pressure of the workpiece 7 on the single conveyor belt structure 312, so that the workpiece 7 can be transmitted better and more smoothly, ensuring the safety of the workpiece 7 during the transmission process, and the transmission component 31 has a simple structure and is easy to install.

[0043] In one embodiment, the conveying assembly 31 further includes a displacement structure, which is connected to at least one support seat 311 and is used to drive the support seat 311 to move closer to or away from another support seat 311 along a conveying direction perpendicular to the conveyor belt structure 312. With such a design, the displacement structure drives the support seat 311 connected thereto to move in a horizontal direction, so that the support seat 311 moves closer to or away from another support seat 311 along a conveying direction perpendicular to the conveyor belt structure 312, thereby adjusting the distance between the two support seats 311, that is, adjusting the distance between the two conveyor belt structures 312, so that the conveying assembly 31 can convey workpieces 7 of different sizes, expand the application range of the patch equipment, and can perform patching on workpieces 7 of different sizes.

[0044] In one embodiment, if Figure 3 As shown, the conveying assembly 31 further includes a slide rail 313 and a slider 314 slidably arranged on the slide rail 313. The slide rail 313 is arranged on the frame 1 along the conveying direction perpendicular to the conveyor belt structure 312. The slider 314 is connected to the support seat 311 connected to the displacement structure. The slide rail 313 and the slider 314 cooperate to guide the movement of the support seat 311, so that the support seat 311 moves along the conveying direction perpendicular to the conveyor belt structure 312, avoiding shaking, and improving the stability of the movement of the support seat 311.

[0045] Preferably, at least two slide rails 313 are spaced apart along the conveying direction of the conveyor belt structure 312, and each slide rail 313 is provided with at least one slider 314; such a design increases the number of slide rails 313, enhances the guiding effect of the slide rails 313 and the slider 314 on the support seat 311, and makes the movement of the support seat 311 smoother.

[0046] In one embodiment, if Figure 3 As shown, the blocking assembly 32 includes a first cylinder 321 disposed on the support seat 311 , and the piston rod of the first cylinder 321 is used to block or not block the workpiece 7 to prevent two adjacent workpieces 7 on the conveying assembly 31 from abutting against each other.

[0047] In this example, the first cylinder 321 is set on the support seat 311, and the first cylinder 321 is located between the two conveyor belt structures 312. The piston rod of the first cylinder 321 is extended and retracted in the vertical direction. When the piston rod of the first cylinder 321 extends and exceeds the top surface of the conveyor belt, the piston rod of the first cylinder 321 can block the workpiece 7 on the conveyor belt; when the piston rod of the first cylinder 321 retracts to not exceed the top surface of the conveyor belt, the piston rod of the first cylinder 321 does not block the workpiece 7 on the conveyor belt, so that the conveyor belt structure 312 can continue to convey the workpiece 7.

[0048] Preferably, the first cylinder 321 is located below the conveyor belt structure 312. Such a design is conducive to rationally planning the installation position of the blocking component 32, making the overall structure of the conveying mechanism 3 more compact and avoiding affecting the operation of other structures.

[0049] Preferably, a plurality of first cylinders 321 are provided, and the plurality of first cylinders 321 are spaced apart along the conveying direction of the conveyor belt structure 312; with such a design, a first cylinder 321 is provided between each two adjacent workpieces 7, so that a plurality of workpieces 7 can be conveyed on the conveying assembly 31 at the same time, and collision between two adjacent workpieces 7 can be prevented, thereby improving processing efficiency.

[0050] Preferably, the blocking assembly 32 also includes a sensor connected to the first cylinder 321. A sensor is provided on one side of each first cylinder 321, and the sensor is used to detect whether the workpiece 7 on the conveyor belt is in place. When it is detected that the workpiece 7 is transmitted to the preset position, the first sensor signal is output to the first cylinder 321, so that the piston rod of the first cylinder 321 extends and exceeds the top surface of the conveyor belt, thereby blocking the workpiece 7 on the conveyor belt.

[0051] In this embodiment, if Figure 3 As shown, the blocking assembly 32 further includes a mounting member 322 disposed on the support seat 311 , and the first cylinder 321 is disposed on the mounting member 322 ; such a design facilitates the installation of the first cylinder 321 .

[0052] In one embodiment, if Figure 3 As shown, the positioning assembly 33 includes a support plate 331, a second cylinder 332 and a clamping member 333; the support plate 331 is arranged on the support seat 311, and is located below the portion of the conveyor belt for supporting the workpiece 7; the second cylinder 332 is arranged on the support seat 311, and the piston rod of the second cylinder 332 is connected to the clamping member 333; the clamping member 333 is used to press the workpiece 7 and the conveyor belt onto the support plate 331 or to separate the conveyor belt and the support plate 331 under the drive of the piston rod of the second cylinder 332.

[0053] In this example, a support plate 331 is arranged below the portion of the conveyor belt for supporting the workpiece 7, and the piston rod of the second cylinder 332 is extended and retracted in the vertical direction, driving the clamping member 333 connected thereto to move in the vertical direction, so that the clamping member 333 presses the workpiece 7 and the conveyor belt against the support plate 331, or separates the conveyor belt from the support plate 331. That is to say, when the workpiece 7 moves to a position relative to the positioning assembly 33, the blocking assembly 32 blocks the workpiece 7, and the conveying assembly 31 stops conveying the workpiece 7. Then, the pressing member 333 moves downward under the drive of the piston rod of the second cylinder 332 to press the workpiece 7 and the conveyor belt against the support plate 331, thereby positioning the workpiece 7 and facilitating the patch mechanism 4 to attach the backing film to the workpiece 7, thereby ensuring the accuracy of the patch; after the pasting is completed, the pressing member 333 moves upward under the drive of the piston rod of the second cylinder 332, so that the conveyor belt is separated from the support plate 331, and the pressing member 333 is separated from the workpiece 7, so that the conveying assembly 31 can continue to convey the workpiece 7. With this design, the positioning assembly 33 has a simple structure, is easy to operate, and is conducive to ensuring the accuracy of the patch of the backing film.

[0054] In one embodiment, if Figure 3 As shown, a positioning assembly 33 is correspondingly provided on each support seat 311. That is to say, the two support seats 311 are provided with positioning assemblies 33, and the positioning assemblies 33 on the two support seats 311 are arranged opposite to each other; in this design, the positioning assemblies 33 on the two support seats 311 simultaneously position the workpiece 7 on the conveyor belt, thereby improving the positioning accuracy of the workpiece 7, preventing the workpiece 7 from moving during the patch process, and improving the patch accuracy of the adhesive backing sheet.

[0055] In one embodiment, if Figure 2 As shown, the patch mechanism 4 includes a moving component 41 arranged on the frame 1, and an adsorption component 42 and a patch component 43 arranged on the moving component 41; the moving component 41 is arranged on the frame 1 and is connected to the adsorption component 42, and is used to drive the adsorption component 42 to move between the feeding mechanism 2 and the conveying component 31; the adsorption component 42 is used to adsorb the back adhesive sheet on the material belt; the patch component 43 is arranged on the frame 1 and is connected to the adsorption component 42, and is used to adjust the direction of the back adhesive sheet and press the back adhesive sheet adsorbed by the adsorption component 42 onto the workpiece 7.

[0056] In this example, the moving component 41 drives the adsorption component 42 to move to a position relative to the feeding mechanism 2, so that the adsorption component 42 adsorbs the back adhesive sheet on the material belt, and then the moving component 41 drives the adsorption component 42 to move to a position relative to the conveying component 31, so that the adsorption component 42 can, driven by the patch component 43, stick the back adhesive sheet adsorbed by the adsorption component 42 on the workpiece 7 to achieve the patch of the workpiece 7. In this design, the moving component 41 and the adsorption component 42 cooperate to achieve the material removal of the back adhesive sheet, which has a simple structure and is easy to operate, and will not cause damage to the back adhesive sheet. Then, the back adhesive sheet is pressed on the workpiece 7 through the patch component 43, which ensures the stability of the bonding between the back adhesive sheet and the workpiece 7 and avoids falling off.

[0057] Preferably, the moving component 41 is a robot.

[0058] In one embodiment, if Figure 3 As shown, the patch component 43 includes a third cylinder arranged on the moving component 41; the piston rod of the third cylinder is connected to the adsorption component 42, and is used to press the adsorption component 42 and the backing film onto the workpiece 7 located on the conveying component 31, or to separate the adsorption component 42 and the backing film.

[0059] In this example, after the moving component 41 drives the adsorption component 42 to move to a position relative to the workpiece 7 on the conveying component 31, the piston rod of the third cylinder extends to press the adsorption component 42 and the backing film onto the workpiece 7. Then, the adsorption component 42 cancels the adsorption of the backing film, and the piston rod of the third cylinder retracts, so that the adsorption component 42 is separated from the backing film, thereby achieving the backing film being attached to the workpiece 7. With this design, the patch component 43 has a simple structure and is easy to operate.

[0060] In one embodiment, if Figure 1 As shown, the patch device further includes a sensing mechanism 5, which is arranged on the patch mechanism 4 and is used to detect the position information of the workpiece 7; the patch mechanism 4 is used to move the backing film onto the workpiece 7 according to the position information. With this design, the sensing mechanism 5 detects the position of the workpiece 7 on the conveying component 31, so that the patch mechanism 4 can perform patching according to the position information, thereby being able to accurately stick the backing film on the workpiece 7, thereby improving the patching accuracy of the backing film.

[0061] In one embodiment, if Figure 1As shown, the patch equipment also includes a detection mechanism 6, which is arranged on the frame 1 and is used to detect whether the adhesive backing sheet is accurately pasted on the workpiece 7.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
