Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a fixing component, an oil cup replacement mechanism and a pad printer. Background Art

[0002] The working principle of an oil cup type pad printer is as follows: An oil cup filled with ink makes a linear reciprocating movement on the surface of a pad printing plate, and the ink in the oil cup fills into the concave patterns on the surface of the pad printing plate during the movement; then, through the vertical downward movement of the pad printing rubber head, the ink filled into the concave patterns is picked up, and then translated above a workpiece table on which a printing workpiece is pre-placed, and then moves downward to press the ink forming a concave pattern on the surface of the pad printing rubber head onto the surface of the printing workpiece, completing the pad printing process. The pad printing process can perform printing on irregular shaped surfaces, for example, it can seal and protect the side edges of a glass substrate.

[0003] When replacing the oil cup in the existing oil cup installation device, usually only allows the oil cup to move in a specific direction. When the operation direction of some process windows conflicts with the above specific direction, the oil cup cannot be replaced.

[0004] Therefore, it is urgent to propose a fixing component, an oil cup replacement mechanism and a pad printer to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fixing component, an oil cup replacement mechanism and a pad printer, which can release the moving direction of the oil cup and meet the disassembly requirements in different directions.

[0031] Such as Figures 1 to 4As shown in the figure, this embodiment provides a fixing component for fixing the oil cup 100 on the pad printing steel plate 200. The fixing component includes a mounting member 1, a fixing member 2, and a locking member 3. The fixing member 2 is used to clamp the oil cup 100. The mounting member 1 is provided with a guide shaft 11 extending in the vertical direction. The fixing member 2 is slidably connected to the guide shaft 11. The fixing member 2 has a clamping position for clamping the oil cup 100 and a release position for disengaging from the oil cup 100. And the fixing member 2 in the release position is located above the oil cup 100. The locking member 3 is used to fix the fixing member 2 in the release position. By providing the guide shaft 11 extending in the vertical direction on the mounting member 1 and slidably connecting the fixing member 2 to the guide shaft 11, the fixing member 2 can move up and down in the vertical direction. When the fixing member 2 is moved downward to the clamping position, the fixing member 2 clamps the oil cup 100, fixing the oil cup 100 on the pad printing steel plate 200. When the fixing member 2 is moved upward to the release position, the fixing member 2 disengages from the oil cup 100, and the fixing member 2 is located above the oil cup 100, enabling the oil cup 100 to move in any horizontal direction. The above setting ensures that when the fixing member 2 is in the release position, it will not cause movement interference to the horizontal movement of the oil cup 100, releasing the moving direction of the oil cup 100 and meeting the disassembly requirements in different directions.

[0032] The locking member 3 is arranged on the fixing member 2. A positioning hole 12 is formed on the mounting member 1. The locking member 3 can be inserted into the positioning hole 12 to fix the fixing member 2 in the release position, facilitating the operator to remove the oil cup 100 from below the fixing member 2 and replace it with a new oil cup 100.

[0033] Specifically, the locking member 3 is a spring plunger. The spring plunger has a pre-tightening force. When the fixing member 2 is moved upward, when the positioning post of the spring plunger moves to the positioning hole 12 of the mounting member 1, the positioning post extends out under the action of the pre-tightening force and enters the positioning hole 12, thus fixing the fixing member 2 in the release position. After replacing the oil cup 100, pull the handle connected to the positioning post to retract the positioning post, and the fixing member 2 can then move downward to clamp the oil cup 100. Among them, the specific structure of the spring plunger belongs to the prior art and will not be elaborated here. Optionally, the locking member 3 includes but is not limited to a bolt or a pin, etc., and will not be defined here.

[0034] As Figures 3 to 4 shown in the figure, the mounting member 1 is provided with a first limiting portion 13 and a second limiting portion 14. One end of the guide shaft 11 is connected to the first limiting portion 13, and the other end of the guide shaft 11 is connected to the second limiting portion 14. Both the first limiting portion 13 and the second limiting portion 14 can abut against the fixing member 2 to limit the displacement stroke of the fixing member 2 in the vertical direction.

[0035] In this embodiment, two guide shafts 11 are provided on the mounting member 1 at intervals, so as to provide better guiding effect for the fixing member 2. Optionally, the number of the guide shafts 11 can also be one, three, four, six, etc., which is not specifically limited herein.

[0036] Furthermore, the guide shaft 11 is a chrome-plated bar, which has high hardness, good wear resistance and corrosion resistance, and a smooth surface, enabling the fixing member 2 to slide smoothly with the guide shaft 11.

[0037] In this embodiment, the fixing member 2 includes a connecting portion 21 and a clamping portion 22. The connecting portion 21 is slidably connected to the guide shaft 11, and the clamping portion 22 is detachably connected to the connecting portion 21. The clamping portion 22 is used for clamping the oil cup 100. By providing the detachably connected connecting portion 21 and clamping portion 22, during installation, first slidably connect the connecting portion 21 with the guide shaft 11, and then connect the clamping portion 22 with the connecting portion 21, which is convenient for the operator to assemble the fixing component.

[0038] Combined Figure 1 and Figure 2 As shown, the oil cup 100 includes an upper portion 110 and a lower portion 120. The cross-sectional dimension of the lower portion 120 is larger than that of the upper portion 110. In this embodiment, when the fixing member 2 is in the clamping position, the clamping portion 22 is sleeved on the upper portion 110, and the bottom surface of the clamping portion 22 abuts against the lower portion 120. The fixing member 2 can drive the oil cup 100 to make a reciprocating motion on the pad printing plate 200, so that the oil cup 100 can drag and scrape the ink on the pad printing plate 200.

[0039] Specifically, an installation hole is formed on the fixing member 2, and the installation hole can be sleeved on the upper portion 110 of the oil cup 100 to realize the clamping and fixing of the oil cup 100. The structure of the fixing member 2 is simple and convenient to operate. Optionally, the fixing member 2 can also be formed by enclosing at least two brackets to form the above installation hole, which is not limited herein.

[0040] Continuing as Figure 2 shown, this embodiment further provides an oil cup replacement mechanism, which includes an oil cup tray 300 and the above-mentioned fixing component. The oil cup tray 300 is arranged at one end of the pad printing plate 200 along its length direction for receiving the oil cup 100, facilitating the operator to take away the oil cup 100 for cleaning work. The above setting can further meet the requirement of replacing the oil cup 100 along the length direction of the pad printing plate 200. Of course, since the operation directions of different process windows are different, when it is necessary to disassemble the oil cup 100 along other directions, the oil cup tray 300 can also be arranged on the preset movement path of the oil cup 100 to facilitate receiving the oil cup 100, which is not limited herein.

[0041] In addition, this embodiment further provides a pad printer, including a pad printing steel plate 200, characterized in that the pad printer includes a driving component 400 and the above-mentioned oil cup replacement mechanism, an installation part 1 is arranged at the output end of the driving component 400, and the driving component 400 is used to drive the fixing component to drive the oil cup 100 to move along the length direction of the pad printing steel plate 200, so that the oil cup 100 can drag and scrape ink on the pad printing steel plate 200.

[0042] Specifically, the driving component 400 includes a driving part 410 and a lead screw module 420. The output end of the driving part 410 is connected to the input end of the lead screw module 420. A slider 421 is arranged at the output end of the lead screw module 420, and the slider 421 is used to be connected to the installation part 1. Through the lead screw module 420, the accuracy and stability of the fixing component moving along the length direction of the pad printing template can be improved. Further, the lead screw module 420 in this embodiment is a linear guide lead screw module, which has the advantages of high positioning accuracy and fast movement speed. In other embodiments, a ball screw module or the like can also be used, which is not limited herein. Among them, the specific structures of the linear guide lead screw module and the ball screw module both belong to the prior art and will not be elaborated herein.

[0043] In this embodiment, the driving part 410 is a servo motor. Optionally, the driving part 410 includes but is not limited to a stepping motor or the like, which is not limited herein.

[0044] Further, at least two sliders 421 are arranged at intervals at the output end of the lead screw module 420, and each slider 421 is used to connect the fixing component, so that the pad printer can drive at least two oil cups 100 to move simultaneously, improving production efficiency.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
