Description

Technical Field

[0001] This application relates to the field of dispensing equipment technology, and in particular to a wide workpiece dispensing machine. Background Technology

[0002] In the dispensing operation of wide-width long roll materials, such as a workpiece measuring 2 meters long and 1.5 meters wide, the roll material first needs to be locally positioned to ensure the stability of the workpiece during dispensing. Secondly, the dispensing needs to be performed on the surface of the wide workpiece according to a pre-set path. Existing dispensing equipment only has a single dispensing machine, resulting in low dispensing efficiency. Furthermore, because the area requiring positioning and fixing during dispensing of wide-width long roll materials is large, the area of ​​the adsorption platform is also large, resulting in a heavy adsorption platform. Therefore, a lifting mechanism with a large output force is required when lifting the adsorption platform. Utility Model Content

[0041] Reference Figure 1-7A wide workpiece dispensing machine includes a base 1, an adsorption platform 2, a lifting module 3, a dispensing mechanism 4, and a three-axis drive mechanism 5. The adsorption platform 2 is slidably mounted on the base 1 in the vertical direction via the lifting module 3. Multiple lifting modules 3 can be provided. The base 1 is provided with a first mounting surface for mounting the lifting module 3. The first mounting surface is made of marble.

[0042] A crossbeam 6 is provided on the base 1, and the crossbeam 6 is positioned above the adsorption platform 2. Multiple dispensing mechanisms 4 are provided, and the dispensing mechanisms 4 are mounted on the crossbeam 6. The crossbeam 6 and the dispensing mechanisms 4 are mounted on the base 1 via a three-axis drive mechanism 5. The three-axis drive mechanism 5 can control the dispensing mechanism 4 to move along the X-axis, Y-axis, and Z-axis directions. Each dispensing mechanism 4 includes a dispensing valve group 41 and a Y-axis auxiliary adjustment component 42. The Y-axis auxiliary adjustment component 42 controls the dispensing valve group 41 to move independently along the Y-axis.

[0043] The lifting module 3 includes a drive assembly, an active block 31, and a driven block 32. The active block 31 is horizontally slidably connected to the base 1 along the Y direction via the drive assembly, and the driven block 32 is fixedly connected to the bottom of the adsorption platform 2. Specifically, the drive assembly includes a screw 33, a control seat 34, and a drive source 35. The screw 33 is rotatably connected to the first mounting surface of the base 1 via a bracket. The drive source 35 is located on the base 1 to drive the screw 33 to rotate. The control seat 34 is threadedly connected to the screw 33 and connected to the active block 31. A horizontal slide rail 36 corresponding to the active block 31 is provided on the first mounting surface of the base 1. The horizontal slide rail 36 is located on both sides of the screw 33. A slider adapted to the horizontal slide rail 36 is connected to the bottom of the active block 31. The first mounting surface is made of marble, which can improve the flatness of the mounting surface of the horizontal slide rail 36, thereby improving the stability and accuracy of the sliding of the active block 31.

[0044] The driven block 32 has a contact surface 37, and the driving block 31 has a support surface 38 opposite to the contact surface 37. The support surface 38 is parallel to the contact surface 37 and slides relative to the contact surface 37 along the plane containing the contact surface 37. During the horizontal movement of the driving block 31, the support surface 38 slides relative to the contact surface 37 along the plane containing the contact surface 37, while the driven block 32 lifts the adsorption platform 2 to move vertically. To improve the smoothness of the relative sliding between the driven block 32 and the driving block 31, a guide rail 39 can be provided on the contact surface 37. The extension direction of the projection of the guide rail 39 on the horizontal plane is parallel to the movement direction of the driving block 31. A slider is connected to the support surface 38, and the slider cooperates with the guide rail 39.

[0045] A guide assembly is also provided between the adsorption platform 2 and the base 1 to guide the movement of the adsorption platform 2 and improve the stability of the sliding of the adsorption platform 2. The guide assembly includes a guide post and a guide cylinder. The guide cylinder is fixedly connected to the base 1, and the guide post is connected to the adsorption platform 2. The guide post passes through the guide cylinder and slides along the axial direction of the guide cylinder. The base 1 is provided with a guide hole to allow the guide post to pass.

[0046] The adsorption platform 2 is used to adsorb and support the workpiece. The adsorption platform 2 has several air channels, and its top surface has multiple air holes communicating with these channels. Specifically, the air channels are divided into multiple transverse air channels and multiple longitudinal air channels. The transverse air channels are spaced apart along the X-axis in the horizontal plane, and the longitudinal air channels are spaced apart along the Y-axis in the horizontal plane. The transverse and longitudinal air channels are perpendicular to each other and interconnected. The air holes are evenly distributed on the top surface of the adsorption platform 2 in a rectangular array.

[0047] The workpiece is adsorbed onto the adsorption platform 2, and the workpiece and the adsorption platform 2 are evenly attached to each other, improving the flatness of the workpiece adsorption; the driving block 31 moves horizontally, and the driven block 32 controls the adsorption platform 2 to rise and fall stably through the tangential cooperation between the contact surface 37 and the support surface 38.

[0048] It should be noted that, during production use, a process module can also be installed on base 1, allowing wide workpieces to be positioned along the X-axis ( Figure 2 The arrow shown indicates the workpiece conveying direction. The workpiece moves to the top of the adsorption platform 2. The two ends of the base 1 opposite to the X-axis are the feeding end and the discharging end, respectively. The process module and the adsorption platform 2 are arranged on the base 1 along the Y-axis. In order to facilitate the maintenance of the lifting module 3 and the installation of the equipment module and other facilities, the drive source 35 is set on the side of the adsorption platform 2 away from the process module, so that the moving direction of the active block 31 is perpendicular to the workpiece feeding and discharging direction.

[0049] The base 1 is provided with a second mounting surface, which has two locations on both sides of the adsorption platform 2. The second mounting surface is made of marble. The three-axis drive mechanism 5 includes a Y-axis main drive assembly 51, an X-axis drive assembly 52, a flexible assembly 54, and a Z-axis drive assembly 53.

[0050] The Y-axis main drive assembly 51 has two sets, each mounted on a second mounting surface, for connecting to both ends of the crossbeam 6 to control the movement of the crossbeam 6 along the Y-axis. The Y-axis main drive assembly 51 includes a guide bar 511, a first slide rail 512, and a slide block 513. Two first slide rails 512 are arranged along the Y-axis, one on each side of the guide bar 511. The slide block 513 slides in conjunction with the guide bar 511, and a slider adapted to the first slide rail 512 is connected to the bottom of the slide block 513.

[0051] The flexible component 54 is disposed between the crossbeam 6 and the Y-axis main drive component 51. The slide block 513 is provided with a support block 514. The flexible component 54 is connected to the support block 514. When the two ends of the crossbeam 6 move at different speeds along the Y-axis, the flexible component 54 can rotate relative to the ends of the crossbeam 6 and move relative to the length of the crossbeam 6, thereby preventing the crossbeam 6 from being subjected to bending moment deformation.

[0052] Preferably, a through groove is provided between the support block 514 and the slide block 513, and a dustproof plate 515 passes through the through groove. The dustproof plate 515 covers the guide bar 511 and the first slide rail 512 to prevent external objects such as screws and dust from entering between the guide bar 511, the first slide rail 512 and the slider, thus affecting the stability and smoothness of the slide block 513 sliding along the Y-axis.

[0053] The X-axis drive assembly 52 is mounted on the crossbeam 6 to control the independent movement of multiple dispensing mechanisms 4 along the X-axis. A second slide rail 521 is connected to the bottom of the crossbeam 6 along the X-axis. Multiple second slide rails 521 are provided, each positioned along the length of the crossbeam 6 on opposite sidewalls. In this embodiment, three second slide rails 521 are provided, positioned at the top and bottom of the back of the crossbeam 6 and at the bottom of the front. The X-axis drive assembly 52 includes a drive device, a bracket, and guide blocks 522 adapted to the three second slide rails 521. The bracket is bent and surrounds the crossbeam 6. Multiple guide blocks 522 are connected to the same bracket. The drive device is connected to the bracket to drive the bracket and guide blocks 522 to move along the length of the second slide rails 521.

[0054] The Y-axis auxiliary adjustment assembly 42 is located at the bottom of the bracket. The Y-axis auxiliary adjustment assembly 42 includes a mounting base 421 and a drive control component 422. The mounting base 421 is slidably connected to the bottom of the bracket along the Y-axis direction via the drive control component 422. The dispensing valve assembly 41 is connected to the mounting base 421 via a Z-axis drive assembly. The dispensing valve assembly 41 includes a vision component, a dispensing valve, and a height measuring component. The vision component is used to detect the dispensing position, and the height measuring component is used to measure the height between the dispensing valve assembly 41 and the workpiece.

[0055] A wide roll of material is laid between the adsorption platform 2 and the dispensing mechanism 4. The adsorption platform 2 adsorbs the roll of material onto itself. The tangential fit between the contact surface 37 and the support surface 38 in the lifting module 3 converts the horizontal driving force into a vertical driving force, lifting the adsorption platform 2 so that it moves towards the dispensing mechanism 4. According to the preset dispensing path, the two dispensing mechanisms 4 perform zoned synchronous dispensing of the roll of material on the adsorption platform 2: the Y-axis auxiliary adjustment component 42 controls the movement of the crossbeam 6 to make the two dispensing mechanisms 4 move synchronously along the Y-axis; the Y-axis auxiliary adjustment component 42 controls the two dispensing mechanisms 4 to move independently along the Y-axis according to their respective dispensing paths; the X-axis drive component 52 controls the two dispensing mechanisms 4 to move independently along the X-axis according to their respective dispensing paths; the lateral auxiliary adjustment component controls the movement of the crossbeam 6 to make the two dispensing mechanisms 4 move synchronously along the X-axis.

[0056] On the one hand, this application transforms the horizontal driving force into the vertical driving force through the mutual cooperation of the contact surface 37 on the active block 31 and the driven block 32, thereby replacing the existing lifting devices such as cylinders. While saving installation space, it achieves a larger output and adsorbs large workpieces onto the adsorption platform 2 to realize the lifting operation of large workpieces.

[0057] On the other hand, by setting up the Y-axis main drive component 51, the X-axis drive component 52, the lateral auxiliary adjustment component and the Y-axis auxiliary adjustment component 42, multiple dispensing mechanisms 4 can move synchronously or independently in the horizontal plane to perform synchronous dispensing on wide workpieces, thereby improving dispensing efficiency.
