Technical Field
[0001] The present application relates to the technical field of screen printing equipment, and in particular to a clamp for screen printing of refrigerator boxes. Background Art
[0002] A screen printer is a machine that uses a screen printing plate to print. Screen printing has the advantages of thick ink layer, rich printing quality, strong three-dimensional effect, strong light resistance and large printing area. The screen printer includes a drive module, and a printing head is installed on the movable end of the drive module; the printing net is fixed on the drive module. The working principle of the screen printer is: the workpiece is placed under the printing net; the drive module drives the printing head to move; the printing head scrapes the printing net through its scraper to print the pattern on the workpiece.
[0003] Due to the limited space under the printing screen, in order to clamp the workpiece, the existing technology usually sets a vacuum suction cup under the printing screen, places the workpiece on the vacuum suction cup, starts the vacuum suction cup to fix the workpiece, and then prints. However, the vacuum suction cup is only suitable for workpieces with regular shapes. The fixing effect of workpieces with irregular shapes and centers of gravity such as refrigerators and refrigeration boxes is poor, and the positioning accuracy of refrigerators and refrigeration boxes is low, resulting in the screen printing product effect not meeting the requirements, so it needs to be improved. Utility Model Content
[0004] In order to improve the positioning accuracy of a refrigerator box, the present application provides a fixture for screen printing of a refrigerator refrigerator box.
[0005] The present application provides a fixture for screen printing of refrigerator boxes using the following technical solutions:
[0006] A fixture for screen printing of refrigerator boxes comprises a workbench, on which a positioning assembly for placing the refrigerator box is arranged, and on which a pressing assembly is installed, and the pressing assembly is used to press the refrigerator box against the positioning assembly; a linear moving module is installed on the workbench, and the positioning assembly is installed on the movable end of the linear moving module, and the linear moving module drives the positioning assembly to approach or move away from the pressing assembly.
[0007] By adopting the above technical solution, the positioning component and the clamping component cooperate to realize the positioning of the cold storage box, improve the accuracy of the cold storage box positioning, and thus improve the printing quality. The setting of the linear moving module allows the positioning component to be out of the coverage of the printing network, providing space and vision for the operator to take and place the cold storage box, improving the accuracy of the cold storage box clamping and at the same time improving the efficiency of the operator's placement.
[0008] Optionally, the positioning assembly includes a positioning plate and a positioning block, the positioning plate is vertically mounted on the movable end of the linear moving module, and the positioning block is mounted on one side of the positioning plate close to the clamping assembly; the positioning block is provided with steps and circular chamfers, the positioning block is adapted to the inner wall of the refrigerated box, and the top plate of the refrigerated box to be printed is mounted on the positioning block.
[0009] By adopting the above technical solution, when the operator places the cold box, he / she holds the cold box so that the opening of the cold box faces the positioning block, and the cold box is clamped on the positioning block. The main body of the cold box remains in a vertical state, and the top wall of the cold box remains in a horizontal state, which improves the accuracy of the cold box positioning, thereby improving the printing quality. In addition, the operation of placing the cold box is relatively simple, and the technical requirements for the operator are relatively low, which reduces the possibility of inaccurate positioning due to manual errors; it can also improve the efficiency of positioning.
[0010] Optionally, the height of the positioning block is smaller than the height of the refrigerated box, the positioning block is adapted to one side of the refrigerated box in the height direction, and a stopper is installed on the positioning plate, and the stopper is used to prevent the refrigerated box from shaking.
[0011] By adopting the above technical solution, when the cold storage box is clamped on the positioning block, the bottom of the cold storage box is suspended and does not contact the horizontal plate, and the side wall of the cold storage box opening is in contact with the side wall of the stopper. Compared with the positioning block of the same volume as the cold storage box, the smaller positioning block has a lower weight, which is convenient for operators to replace the positioning block and improves the practicality of the clamp. The bottom of the cold storage box is suspended and does not contact the horizontal plate, which reduces the possibility of wear caused by the cold storage box contacting metal.
[0012] Optionally, the clamping assembly includes a mounting plate, a clamping block and a driving member, the mounting plate is vertically mounted on the workbench, the driving member is mounted on the mounting plate, the clamping block is mounted on the movable end of the driving member, the driving member drives the clamping block to move closer to or away from a refrigerated box placed on the positioning block, and the side wall of the clamping block away from the driving member is adapted to the side wall of the refrigerated box.
[0013] Optionally, a cover plate is installed on the abutting block, and the cover plate can cover the portion of the top wall of the refrigeration box that does not need to be printed, and the top wall of the cover plate is smoothly connected to the top wall of the refrigeration box.
[0014] By adopting the above technical solution, when the cold storage box is clamped on the positioning block and moved to the position aligned with the pressing block, the driving member is started, driving the pressing block to approach the cold storage box and press the cold storage box against the positioning block. The positioning block and the pressing block cooperate to realize the positioning of the cold storage box, improve the positioning accuracy of the cold storage box, and thus improve the printing quality. The cover plate covers the part of the top wall of the cold storage box that does not need to be printed, improves the printing accuracy, and reduces the occurrence of printing beyond the range.
[0015] Optionally, the positioning block is detachably connected to the positioning plate, and the abutting block is detachably connected to the driving member, so as to adapt to different models of cold storage boxes.
[0016] By adopting the above technical solution, when the specifications of the refrigerated box change, the positioning block and the positioning plate are disassembled and connected by bolts, and the abutting block and the driving member are disassembled and connected by bolts, so that the operator can easily replace the positioning block and the abutting block to adapt to different refrigerated boxes, thereby improving the positioning accuracy and the practicality of the clamp.
[0017] Optionally, the moving direction of the linear motion module is perpendicular to the moving direction of the driving member, and one end of the linear motion module is disposed close to the mounting plate.
[0018] By adopting the above technical solution, the length direction of the linear moving module is perpendicular to the length direction of the printing net, and the length direction of the driving member is parallel to the length direction of the printing net. When placing the cold storage box, the operator stands on the side of the workbench away from the printing net, and one end of the linear moving module is close to the operator. The ergonomic design is convenient for the operator to place the cold storage box and improves the efficiency of placing the cold storage box. After the cold storage box is placed on the positioning block, the linear moving module drives the cold storage box on the positioning block to move to the bottom of the printing net and stops at the intersection of the extension line of the length direction of the driving member and the linear moving module. After printing is completed, the driving member drives the pressing block to retract and disengage from the cold storage box, and the linear moving module drives the cold storage box on the positioning block to approach the operator. The vertical setting of the linear moving module and the driving member compared to the parallel setting can effectively reduce the area of the workbench, and at the same time is more ergonomic, which is convenient for the operator to take and place the cold storage box. Compared with the prior art which requires sufficient space to place the vacuum suction cup, the printing screen of the present application only needs to drop a shorter distance to contact the top wall of the cold storage box, thereby reducing the working cycle of the printing machine and improving printing efficiency.
[0019] Optionally, the outer surface of the positioning block is covered with fabric, and the fabric is flannel.
[0020] By adopting the above technical solution, the contact points between the positioning block and the cold storage box are covered with flannel, which reduces the possibility of wear between the cold storage box and the metal; at the same time, the flannel can provide a certain friction force, reducing the possibility of the cold storage box detaching from the positioning block during movement.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. The positioning component and the clamping component cooperate to realize the positioning of the cold storage box, improve the positioning accuracy of the cold storage box, and thus improve the printing quality. The setting of the linear moving module allows the positioning component to be out of the coverage of the printing network, providing space and vision for the operator to take and place the cold storage box, improving the accuracy of the cold storage box clamping and at the same time improving the efficiency of the operator's placement;
[0023] 2. When the cold storage box is stuck on the positioning block and moved to the position aligned with the pressing block, the driving member starts, drives the pressing block to approach the cold storage box, and presses the cold storage box against the positioning block. The positioning block and the pressing block cooperate to realize the positioning of the cold storage box, improve the positioning accuracy of the cold storage box, and thus improve the printing quality. The cover plate covers the part of the top wall of the cold storage box that does not need to be printed, improves the printing accuracy, and reduces the occurrence of printing beyond the range;
[0024] 3. The length direction of the linear moving module is perpendicular to the length direction of the printing net, and the length direction of the driving member is parallel to the length direction of the printing net. When placing the cold storage box, the operator stands on the side of the workbench away from the printing net, and one end of the linear moving module is close to the operator. The ergonomic design is convenient for the operator to place the cold storage box and improve the efficiency of placing the cold storage box. After the cold storage box is placed on the positioning block, the linear moving module drives the cold storage box on the positioning block to move below the printing net and stops at the intersection of the extension line of the length direction of the driving member and the linear moving module. After printing is completed, the driving member drives the pressing block to retract and disengage from the cold storage box, and the linear moving module drives the cold storage box on the positioning block to approach the operator. The vertical setting of the linear moving module and the driving member in contrast to the parallel setting can effectively reduce the area of the workbench, and at the same time, it is more ergonomically designed, which is convenient for the operator to take and place the cold storage box. Compared with the prior art that uses vacuum suction cups and requires sufficient space for placement, the printing net of this application only needs to drop a smaller distance to contact the top wall of the cold storage box, reducing the working rhythm of the printing press, thereby improving the efficiency of printing.

[0028] The following is combined with Figure 1-2 This application is described in further detail.
[0029] The present application embodiment discloses a fixture for screen printing of refrigerator boxes. Figure 1A fixture for screen printing of refrigerator boxes includes a workbench 1, which is horizontally placed on the table and located below a printing screen 8; the printing screen 8 is installed on the movable end of a driving module 6, the fixed end of the driving module 6 is connected to the table, and a printing head 7 is also installed on the movable end of the driving module 6. A linear moving module 2 is installed on the workbench 1, and one end of the linear moving module 2 protrudes from the projection range of the printing screen 8 on the workbench 1. A positioning component 3 is installed on the movable end of the linear moving module 2, and a refrigerator box 5 can be placed on the positioning component 3. A tightening component 4 is also installed on the workbench 1, and the tightening component 4 is arranged below the printing screen 8 and located within the projection range of the printing screen 8 on the workbench 1; the tightening component 4 is used to tighten the refrigerator box 5 against the positioning component 3.
[0030] When screen printing is required, the linear moving module 2 drives the positioning component 3 to leave the projection range of the printing screen 8, and the operator clamps the cold storage box 5 on the positioning component 3. The linear moving module 2 drives the positioning component 3 back to the bottom of the printing screen 8, and the positioning component 3 is aligned with the pressing component 4. The pressing component 4 presses the cold storage box 5 against the positioning component 3, and the positioning of the cold storage box 5 is completed. The top wall of the cold storage box 5 that needs to be printed is in a horizontal state. The driving module 6 starts to drive the printing screen 8 to cover the top wall of the cold storage box 5, and the printing head 7 prints. After printing is completed, the printing screen 8 and the printing head 7 are reset. The pressing component 4 is released, and the linear moving module 2 drives the positioning component 3 to leave the projection range of the printing screen 8. The operator removes the printed cold storage box 5, puts a new cold storage box 5, and repeats the above steps to accurately print the cold storage box 5.
[0031] The positioning component 3 and the pressing component 4 cooperate to realize the positioning of the cold storage box 5, improve the positioning accuracy of the cold storage box 5, and thus improve the printing quality. The setting of the linear moving module 2 enables the positioning component 3 to be out of the coverage of the printing screen 8, providing space and vision for the operator to take and place the cold storage box 5, improving the accuracy of the cold storage box 5 and improving the efficiency of the operator's placement.
[0032] Reference Figure 1 and Figure 2The positioning assembly 3 includes a positioning plate 31, a horizontal plate 34 is installed on the movable end of the linear moving module 2 by bolts, the positioning plate 31 is vertically installed on the horizontal plate 34 by bolts, and the positioning plate 31 and the horizontal plate 34 are reinforced and connected by a right-angle plate. A guide rail is also installed on one side of the linear moving module 2, and the end of the horizontal plate 34 away from the positioning plate 31 is slidably set on the guide rail. A positioning block 32 is installed on the side wall of the positioning plate 31 close to the tightening assembly 4, and the positioning block 32 is connected to the positioning plate 31 by bolts. Due to the irregular shape of the inner wall of the cold storage box 5, the positioning block 32 is provided with steps and arc chamfers, and the outer wall of the positioning block 32 is adapted to the inner wall of the cold storage box 5. The top plate of the cold storage box 5 that needs to be printed is mounted on the positioning block 32, so that the top wall of the cold storage box 5 that needs to be printed is in a horizontal state, which is convenient for printing.
[0033] The height of the positioning block 32 is less than the height of the cold storage box 5. The positioning block 32 is installed at the top of the positioning plate 31, and the positioning block 32 is adapted to the inner wall of the top of the cold storage box 5. Due to the uneven center of gravity of the cold storage box 5, a stopper 33 is installed at the bottom of the positioning plate 31, and the stopper 33 is installed on the side wall of the positioning plate 31 close to the tightening component 4 by bolts. The side wall of the cold storage box 5 can be against the side wall of the baffle to prevent the cold storage box 5 from shaking. The material of the stopper 33 is wood; the outer surface of the positioning block 32 is covered with fabric, and the fabric is flannel.
[0034] When the operator places the cold storage box 5, he holds the cold storage box 5 so that the opening of the cold storage box 5 faces the positioning block 32, and the cold storage box 5 is clamped on the positioning block 32. The contact points between the positioning block 32 and the cold storage box 5 are covered with flannel, which reduces the possibility of wear and tear caused by contact between the cold storage box 5 and metal; at the same time, the flannel can provide a certain friction force, which reduces the possibility of the cold storage box 5 detaching from the positioning block 32 during movement. The bottom of the cold storage box 5 is suspended and does not contact the horizontal plate 34. The side wall of the opening of the cold storage box 5 is in contact with the side wall of the block 33, so that the main body of the cold storage box 5 remains in a vertical state, and the top wall of the cold storage box 5 remains in a horizontal state, which improves the stability of the placement of the cold storage box 5; and the material of the block 33 is wood, which reduces the possibility of wear and tear caused by contact between the cold storage box 5 and metal.
[0035] When the specification of the cold storage box 5 changes, the positioning block 32 and the positioning plate 31 are detachably connected by bolts, so that the operator can replace the positioning block 32 to adapt to different cold storage boxes 5, thereby improving the practicality of the clamp.
[0036] Reference Figure 2The abutting assembly 4 includes a mounting plate 41, which is vertically mounted on the workbench 1 by bolts, and the mounting plate 41 is located within the projection range of the printing screen 8 on the workbench 1. A driving member 42 is mounted on the top of the mounting plate 41. In this embodiment, the driving member 42 is a cylinder, and the cylinder body of the cylinder is mounted on the side wall of the mounting plate 41 away from the positioning block 32 by bolts. A through hole is opened on the mounting plate 41, and the cylinder shaft of the driving member 42 extends from the through hole to the side of the mounting plate 41 close to the positioning block 32. A abutting block 43 is mounted on the cylinder shaft of the driving member 42, and the abutting block 43 is connected to the cylinder shaft of the driving member 42 by bolts. The driving member 42 drives the abutting block 43 to approach or move away from the cold storage box 5 placed on the positioning block 32.
[0037] In this embodiment, the moving direction of the driving member 42 is perpendicular to the moving direction of the linear moving module 2, that is, the length direction of the linear moving module 2 is perpendicular to the length direction of the printing screen 8, and the length direction of the driving member 42 is parallel to the length direction of the printing screen 8. The mounting plate 41 is disposed near one end of the linear moving module 2 near the printing screen 8.
[0038] The shape of the abutting block 43 is adapted to the shape of the cold storage box 5, and the side wall of the abutting block 43 away from the driving member 42 can abut against the side wall of the cold storage box 5. A cover plate 44 is installed on the abutting block 43, and the cover plate 44 is integrally formed with the abutting block 43. The cover plate 44 can cover the portion of the top wall of the cold storage box 5 that does not need to be printed, and the top wall of the cover plate 44 is smoothly connected to the top wall of the cold storage box 5.
[0039] When placing the cold storage box 5, the operator stands on the side of the workbench 1 away from the printing screen 8, and one end of the linear moving module 2 is close to the operator. The ergonomic design is convenient for the operator to place the cold storage box 5 and improves the efficiency of placing the cold storage box 5. After the cold storage box 5 is placed on the positioning block 32, the linear moving module 2 drives the cold storage box 5 on the positioning block 32 to move below the printing screen 8 and stops at the intersection of the extension line of the length direction of the driving member 42 and the linear moving module 2. The driving member 42 starts to drive the pressing block 43 to approach the cold storage box 5, and presses the cold storage box 5 against the positioning block 32. The cover plate 44 covers the part of the top wall of the cold storage box 5 that does not need to be printed, thereby improving the accuracy of positioning and printing and reducing the occurrence of printing out of range. After printing is completed, the driving member 42 drives the pressing block 43 to retract and disengage from the cold storage box 5, and the linear moving module 2 drives the cold storage box 5 on the positioning block 32 to approach the operator.
[0040] The vertical arrangement of the linear moving module 2 and the driving member 42, as opposed to the parallel arrangement, can effectively reduce the area of the workbench 1, and is more ergonomically designed, making it easier for operators to take and place the cold storage box 5. Compared with the prior art that uses a vacuum suction cup that requires sufficient space for placement, the printing screen 8 of the present application only needs to drop a shorter distance to contact the top wall of the cold storage box 5, reducing the working beat of the printing machine, thereby improving the printing efficiency.
[0041] When the specification of the refrigerated box 5 changes, the abutting block 43 and the driving member 42 are detachably connected by bolts, so that the operator can replace the abutting block 43 to adapt to different refrigerated boxes 5, thereby improving the practicality of the clamp.
[0042] The implementation principle of a fixture for screen printing of refrigerator boxes in the embodiment of the present application is as follows: when screen printing is required, the operator selects the positioning block 32 and the pressing block 43 adapted to the refrigerator box 5 according to the specifications of the refrigerator box 5. The linear moving module 2 drives the positioning block 32 to leave the projection range of the printing net 8, and the operator clamps the refrigerator box 5 on the positioning block 32, and the linear moving module 2 drives the refrigerator box 5 on the positioning block 32 to reach the bottom of the printing net 8. The driving member 42 drives the pressing block 43 to press the refrigerator box 5 against the positioning block 32 to achieve precise positioning; at the same time, the cover plate 44 covers the part of the top wall of the refrigerator box 5 that does not need to be printed. After the printing machine is completed, the pressing block 43 releases the restriction on the refrigerator box 5, and the linear moving module 2 drives the refrigerator box 5 on the positioning block 32 to leave the projection range of the printing net 8. The operator removes the printed refrigerator box 5 and puts a new refrigerator box 5, and repeats the above steps to accurately print the refrigerator box 5. The positioning block 32 and the pressing block 43 cooperate to realize the positioning of the cold storage box 5, improve the positioning accuracy of the cold storage box 5, and thus improve the printing quality. The setting of the linear moving module 2 enables the positioning block 32 to be out of the coverage of the printing screen 8, providing space and vision for the operator to take and place the cold storage box 5, improving the accuracy of the cold storage box 5 and improving the efficiency of the operator's placement.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
