Abstract
Description
Technical Field
[0001] This utility model relates to roller transmission, specifically a roller transmission structure for an etching machine. Background Technology
[0002] The rollers of an etching machine are mainly used to transport the substrate to be etched, such as circuit boards and metal strips, so that the substrate can move smoothly and accurately between the various processing areas of the etching machine to complete the etching process.
[0003] The roller drive structure is the core mechanical system that enables precise roller rotation, smooth substrate transmission, or uniform etching medium action, meeting the stringent requirements of etching processes for transmission accuracy, stability, and corrosion resistance.
[0004] Traditional rigid couplings are prone to coaxiality deviations due to their structural characteristics, causing radial runout during drum rotation. This runout directly leads to substrate transport misalignment, resulting in defects such as etched pattern misalignment and edge burrs. This not only significantly reduces the stability of substrate transport but also leads to a decrease in product yield, failing to meet the stringent requirements of precision etching processes for transmission accuracy and stability, thus becoming a key bottleneck restricting the improvement of etched product quality. Utility Model Content
[0005] This utility model addresses the technical problems existing in the prior art by providing a roller drive structure for an etching machine.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] The roller includes a roller with a drum in the middle of its outer surface, driven cone sleeves at both ends of the roller, a sealing ring I on both sides of the outer surface of the roller, a driving cone head at the end of the driven cone sleeve away from the roller, and a sealing ring II between the driving cone head and the driven cone sleeve.
[0008] The driven cone sleeve includes a coupling sleeve, and four mounting plates are fixedly connected to one end of the coupling sleeve near the roller. The mounting plates can be inserted into one end of the roller. The coupling sleeve includes a bushing body, and a positioning groove is provided in the middle of the end of the bushing body away from the roller.
[0009] The beneficial effects of this invention are as follows: the active cone head and the driven cone sleeve are coupled and transmitted through a suitable conical structure. Utilizing the precise fitting characteristics of the double-conical surfaces, the roller and drum rotate synchronously. The disc spring inside the driven cone sleeve can adaptively compensate for the coaxiality deviation between the motor shaft and the roller through elastic deformation, avoiding the operational jumps that are prone to occur in traditional rigid transmissions. Simultaneously, the double-conical surface fitting design effectively increases the transmission contact area, improves the stability of torque transmission, prevents slippage during transmission, and thus ensures smooth substrate transmission, effectively controls transmission offset, and guarantees the precision of the etching process.
[0010] Furthermore, the positioning groove is conical, and several butterfly springs are provided inside the bushing body at the conical head of the positioning groove.
[0011] Furthermore, the inner wall of the positioning groove is evenly provided with several slots.
[0012] Furthermore, the active cone head includes a cone head body, one end of which is fixedly connected to a driven cone tooth, and the end of the cone head body away from the driven cone tooth is conical.
[0013] Furthermore, the conical part of the cone-shaped body is adapted to the positioning groove.
[0014] Furthermore, a number of driving teeth are fixedly connected to the outer surface of the conical part of the cone head body, and the driving teeth are adapted to the slot. Attached Figure Description

[0028] Figure 1 This is a structural diagram of a roller drive structure for an etching machine, provided as an embodiment of the present invention. Figure 1 The device includes a roller 2, a drum 1 is provided in the middle of the outer surface of the roller 2, a driven cone sleeve 4 is provided at both ends of the roller 2, a sealing ring 3 is provided on both sides of the outer surface of the roller 2, an active cone head 6 is provided at the end of the driven cone sleeve 4 away from the roller 2, and a sealing ring 5 is provided between the active cone head 6 and the driven cone sleeve 4.
[0029] Roller 1 is fixed in the middle of roller 2, making roller 2 the core of force bearing and transmission of roller 1; driven cone sleeves 4 are installed at both ends of roller 2, forming the linkage base of roller 2 and driven cone sleeve 4, ensuring that power can be evenly transmitted to roller 2 from both ends, driving roller 1 to rotate smoothly; driving cone head 6 docks with driven cone sleeve 4, building a transmission bridge between external power and roller 2, realizing effective power transmission; sealing ring 1 3 can prevent etching liquid from seeping in from the gap between roller 2 and driven cone sleeve 4, protecting the connection part of roller 2 and driven cone sleeve 4; sealing ring 2 5 between driving cone head 6 and driven cone sleeve 4 can prevent etching liquid from intruding into the transmission docking surface of the two, avoiding corrosion that affects transmission accuracy.
[0030] Figure 2 This is an exploded view of the overall structure of this utility model. (See diagram below.) Figure 2 As shown, the driven cone sleeve 4 includes a coupling sleeve 42. Four mounting plates 41 are fixedly connected to one end of the coupling sleeve 42 near the roller 2. The mounting plates 41 can be inserted into one end of the roller 2.
[0031] The coupling sleeve 42 is precisely inserted into the reserved slots at both ends of the roller 2 through four mounting plates 41 fixed at one end, so as to realize the quick positioning and fixation of the coupling sleeve 42 and the roller 2, ensure that the two are tightly connected, avoid relative displacement during transmission, and provide a stable connection basis for torque transmission.
[0032] Figure 3 This is a sectional view of the coupling sleeve structure of this utility model. Figure 3 As shown, the coupling sleeve 42 includes a sleeve body 421. A positioning groove 423 is provided in the middle of the end of the sleeve body 421 away from the roller 2. The positioning groove 423 is conical. Several butterfly springs 422 are provided inside the sleeve body 421 at the cone head of the positioning groove 423. Several slots 424 are evenly provided on the inner wall of the positioning groove 423.
[0033] The conical positioning groove 423 provides a precise positioning reference for docking with the active cone head 6; the butterfly spring 422 at the cone head of the positioning groove 423 is in a pre-compressed state, which can provide elastic buffer during subsequent docking; the slot 424 on the inner wall of the positioning groove 423 reserves meshing space for the transmission of transmission torque, ensuring subsequent adaptation and transmission with the active cone head 6.
[0034] Example 2
[0035] Based on Embodiment 1, the present invention can be further improved as follows: Figure 4 This is a schematic diagram of the active cone head structure of this utility model. Figure 5 This is a cross-sectional view of the active cone head assembly of this utility model. Figure 4 and Figure 5 As shown, the active cone head 6 includes a cone head body 62. One end of the cone head body 62 is fixedly connected to a driven bevel tooth 63. The end of the cone head body 62 away from the driven bevel tooth 63 is conical. The conical part of the cone head body 62 is adapted to the positioning groove 423. Several driving teeth 61 are fixedly connected to the outer surface of the conical part of the cone head body 62. The several driving teeth 61 are adapted to the groove 424.
[0036] The conical part of the cone head body 62, which is away from the driven bevel tooth 63, fits precisely with the positioning groove 423 of the coupling sleeve 42. At the same time, the drive tooth 61 on the outer surface of the cone head body 62 is embedded in the groove 424 on the inner wall of the positioning groove 423, forming a meshing fixation. External power is transmitted to the cone head body 62 through the driven bevel tooth 63, and then through the meshing action of the drive tooth 61 and the groove 424, it drives the driven cone sleeve 4 and the roller 2 to rotate synchronously, thereby driving the roller 1 to rotate and realizing the smooth transmission of the substrate.
