Description

Technical Field

[0001] This utility model relates to a positioning device, specifically a positioning device for ceramic resistor elements used in screen printing. Background Technology

[0002] Screen printing belongs to the stencil printing technique, one of the four major printing methods (relief printing, gravure printing, offset printing, and stencil printing). In screen printing, the mesh openings in the image areas allow ink to pass through onto the substrate, while the remaining areas of the stencil are blocked, preventing ink from passing through and creating blank areas on the substrate. Screen printing involves weaving silk, synthetic fibers, or metal wires into a mesh, stretching it tightly onto a frame, and creating the stencil using manual cutting or photochemical methods. Only the image areas on the stencil allow ink to pass through, while the non-image areas are completely blocked, preventing ink from seeping through.

[0003] The printing substrates are very diverse, covering various industries, such as paper printing, plastic printing, wood product printing, metal product printing, glass and ceramic product printing, signage printing, circuit board printing, and so on. In the printing process of ceramic resistor elements, multiple rectangular ceramic resistor elements are mounted in rectangular placement slots of a fixture, and the fixture transports multiple ceramic resistor elements for simultaneous printing, thereby achieving batch printing.

[0004] Furthermore, because there is a certain gap between the inner wall of the fixture's placement slot and the outer wall of the ceramic resistor element, the positions of different ceramic resistor elements are not uniform. Before formal printing, all ceramic resistor elements need to be positioned in their designated locations for accurate printing. However, the current positioning operation is mainly done manually, which is time-consuming and labor-intensive, and the work efficiency needs to be improved. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide a ceramic resistor element positioning device for screen printing. This ceramic resistor element positioning device can automatically complete the positioning operation, which is beneficial to improving work efficiency.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A ceramic resistor element positioning device for screen printing includes a positioning mounting platform and a first inclined edge positioning mechanism and a second inclined edge positioning mechanism disposed on the positioning mounting platform.

[0008] The first tilting edge positioning mechanism includes a first tilting edge positioning plate and a first tilting drive mechanism for driving the first tilting edge positioning plate to flip.

[0009] The second tilting edge positioning mechanism includes a second tilting edge positioning plate and a second tilting drive mechanism for driving the second tilting edge positioning plate to flip.

[0010] One end of the first inclined side positioning plate is hinged to the second inclined side positioning plate, and one end of the second inclined side positioning plate is connected to the positioning and mounting platform; the rotation center of the first inclined side positioning plate and the rotation center of the second inclined side positioning plate are perpendicular to each other.

[0011] The working principle of the ceramic resistor element positioning device used for screen printing is as follows:

[0012] During operation, the fixture containing the ceramic resistor elements to be printed is placed on the first inclined side positioning plate. The first inclined driving mechanism drives the first inclined side positioning plate to rotate around its rotation center, so that the fixture changes from a horizontal posture to an inclined posture. At this time, all the ceramic resistor elements in the fixture are close to the side of the placement slot parallel to the rotation center of the first inclined side positioning plate, completing the positioning operation in one direction.

[0013] The second tilting drive mechanism drives the second tilting side positioning plate to rotate around its rotation center. At this time, the second tilting side positioning plate tilts in another direction, so that all the ceramic resistor elements in the fixture are close to the side of the placement groove that is parallel to the rotation center of the second tilting side positioning plate, thus completing the positioning operation in another direction. At this time, the ceramic resistor elements are in close contact with the two adjacent inner walls of the placement groove. Thus, the positioning of the ceramic resistor elements is achieved in two mutually perpendicular directions.

[0014] In a preferred embodiment of this invention, the first tilting drive mechanism includes a first tilting drive cylinder. The cylinder body of the first tilting drive cylinder is directly or indirectly hinged to the second tilting edge positioning plate, and the telescopic rod of the first tilting drive cylinder is directly or indirectly hinged to the first tilting edge positioning plate. With this structure, under the drive of the first tilting drive cylinder, the first tilting edge positioning plate can rotate around its rotation center, tilting the fixture so that the ceramic resistor element is automatically positioned at the edge.

[0015] Furthermore, the positioning and installation platform is provided with a first clearance hole, and the second inclined side positioning plate is provided with a second clearance hole;

[0016] The telescopic rod of the first tilting drive cylinder passes through the first and second clearance holes and is hinged to the first tilting edge positioning plate via a first hinge; the cylinder body of the first tilting drive cylinder is hinged to the second tilting edge positioning plate via a second hinge, which passes through the first clearance hole and is fixed to the second tilting edge positioning plate. With this structure, the first tilting drive mechanism can be positioned below the first tilting edge positioning plate, thus not occupying the space above the first tilting edge positioning plate, resulting in a more compact structure.

[0017] Furthermore, the first tilting drive cylinder is a stroke-adjustable cylinder to adapt to different tilting angles.

[0018] In a preferred embodiment of this invention, the second tilting drive mechanism includes a second tilting drive cylinder. The cylinder body of the second tilting drive cylinder is directly or indirectly hinged to the positioning and mounting platform, and the telescopic rod of the second tilting drive cylinder is directly or indirectly hinged to the second tilting edge positioning plate. With this structure, under the drive of the second tilting drive cylinder, the second tilting edge positioning plate can rotate around its rotation center, tilting the fixture so that the ceramic resistor element is automatically positioned at the edge.

[0019] Furthermore, the positioning and mounting platform is provided with a third clearance hole. The telescopic rod of the second tilting drive cylinder passes through the third clearance hole and is hinged to the second tilting edge positioning plate via a third hinge. The cylinder body of the second tilting drive cylinder is hinged to the positioning and mounting platform via a fourth hinge. With the above structure, the second tilting drive mechanism can be arranged below the second tilting edge positioning plate, thus not occupying the space above the second tilting edge positioning plate, resulting in a more compact structure.

[0020] Furthermore, the second tilting drive cylinder is a stroke-adjustable cylinder to adapt to different tilting angles.

[0021] In a preferred embodiment of the present invention, the first inclined side positioning mechanism further includes a first buffer, the housing of which is fixed to the second inclined side positioning plate, and the buffer contact end of which extends toward the first inclined side positioning plate.

[0022] In a preferred embodiment of the present invention, the second inclined side positioning mechanism further includes a second buffer, the housing of which is fixed on the positioning and mounting platform, and the buffer contact end of which extends toward the second inclined side positioning plate.

[0023] The above structure can provide a buffer for the reset of the first and second inclined side positioning plates, avoid large vibrations in the fixture, and prevent the ceramic resistor element positioned in the fixture from shifting.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The ceramic resistor element positioning device of this utility model can automatically complete the positioning operation, which is beneficial to improving work efficiency.

[0026] 2. By flipping and tilting the fixture around two perpendicular directions, the ceramic resistor element can be tightly attached to the two adjacent inner walls of the placement slot, thereby achieving the positioning of the ceramic resistor element in two mutually perpendicular directions. The operation is simple and the structure is compact. Attached Figure Description
