Description

Technical Field

[0001] This utility model relates to a stable drive structure for a hanger used in an electroplating production line, belonging to the technical field of electroplating equipment. Background Technology

[0002] On an electroplating production line, the hanger typically moves by engaging a ratchet on it with a rack on the transmission belt. Specifically, the rack is installed along the length of the chain and its size is adapted to the equipment specifications. The hanger moves along the conveyor belt by engaging the ratchet with the rack.

[0003] Since racks are mostly injection molded parts, they are prone to local damage due to material properties, which leads to a decrease in the meshing accuracy between the rack and the ratchet. At the same time, traditional ratchets have fewer teeth and a fixed tooth pitch, which can easily cause backlash during meshing. Backlash can cause displacement deviations during the movement of the hanger, which can cause the hanger to get stuck or even cause the hangers to overlap. This not only affects the normal operating efficiency of the equipment, but may also increase production costs due to frequent downtime for maintenance, and may even pose safety hazards. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stable drive structure for a hanger used in an electroplating production line.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a stable drive structure for a hanger used in an electroplating production line, comprising...

[0006] A drive assembly is installed on the electroplating production line. The drive assembly includes a transmission chain and a drive gear for driving the transmission chain to move. Multiple racks are fixedly arranged on the outer side of the transmission chain. The multiple racks are arranged continuously and aligned. Each rack has an array of toothed structures located on the side of the rack away from the transmission chain.

[0007] The hanger body is slidably mounted on the electroplating production line. Multiple ratchet wheels are equidistantly arranged at the front end of the hanger body. Each ratchet wheel has three staggered teeth. The three teeth respectively mesh with adjacent tooth structures on the rack to drive the hanger body to move.

[0008] The width of the three locking teeth decreases from the side closer to the hanger body to the side farther away from the hanger body, and the height of the three locking teeth decreases sequentially from the side closer to the hanger body to the side farther away from the hanger body.

[0009] Preferably, the front end of the hanger body is provided with a bearing component, and the plurality of ratchet wheels are obliquely fixed to the bearing component by bolts.

[0010] Preferably, the ratchet is installed in the opposite direction to the travel direction of the hanger body.

[0011] Preferably, the transmission chain is provided with a mounting part, and the rack is provided with a mounting hole, through which the rack is fixed to the mounting part of the transmission chain by bolts.

[0012] Preferably, the rack is an injection molded part, and both sides of the rack are provided with intersecting horizontal and vertical reinforcing ribs.

[0013] Preferably, the hanger body is provided with multiple guide wheels.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] 1. In this utility model, the three teeth of each ratchet are staggered and decrease in size, and can mesh with the three adjacent tooth structures on the rack at the same time. The tooth backlash error is dispersed by multi-tooth contact. At the same time, the gradient design of the height and width of the teeth can adapt to the slight deformation of the rack, ensuring that there is no obvious gap during the meshing process, effectively avoiding displacement deviation when the hanger moves, and reducing the risk of jamming or overlapping.

[0016] 2. By equidistantly setting multiple ratchets and designing multiple locking teeth for each ratchet, the force on a single rack can be distributed. Even if a section of the rack is partially damaged, the other locking teeth can still maintain effective engagement, avoiding interruption of the overall transmission due to single-point failure and extending the continuous operation time of the equipment.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] As attached Figure 1-5 As shown, the present invention provides a stable drive structure for a hanger used in an electroplating production line, comprising a drive component 1 and a hanger body 3. The drive component 1 is installed on the electroplating production line to provide driving force, and the hanger body 3 is slidably installed on the electroplating production line. Specifically, a guide rail structure commonly used in the art can be adopted to allow the hanger body 3 to move along the guide rail direction.

[0028] As attached Figure 2-3 As shown, the drive assembly 1 includes a transmission chain 11 and a drive gear 12 for driving the transmission chain 11 to move. In this embodiment, the drive gear 12 is a spur gear. The drive gear 12 can be connected to a drive device (such as a servo motor) on the electroplating production line to provide driving force.

[0029] Multiple racks 2 are fixedly provided on the outer side of the transmission chain 11. In this embodiment, the racks 2 are injection molded parts. Specifically, the transmission chain 11 is provided with a mounting part 111, which can be fixed to the outer chain plate of the transmission chain 11. The racks 2 are provided with mounting holes 22, and the racks 2 are fixed to the mounting part 111 of the transmission chain 11 through the mounting holes 22 and bolts. Multiple racks 2 are arranged continuously and aligned, and each rack 2 has an array of toothed structures 21. The toothed structures 21 are located on the side of the rack 2 away from the transmission chain 11.

[0030] As attached Figure 4 , 5 As shown in Figure 7, multiple ratchet wheels 31 are equidistantly arranged at the front end of the hanger body 3. In this embodiment, the hanger body 3 is a metal frame structure used to suspend the workpiece to be electroplated. A bearing component 32 is provided at the front end of the hanger body 3. The multiple ratchet wheels 31 are all fixed to the bearing component 32 at an angle by bolts. The installation direction of the ratchet wheels 31 is opposite to the travel direction of the hanger body 3. The angled connection between the ratchet wheels 31 and the bearing component 32 can increase the meshing contact area and reduce local wear.

[0031] Furthermore, each ratchet 31 has three staggered teeth 311, which mesh with adjacent toothed structures 21 on the rack 2 to drive the hanger body 3 to move. The spacing between the toothed structures 21 on the rack 2 matches the staggered distance of the three teeth 311, ensuring that the three teeth 311 always remain engaged with the adjacent toothed structures 21 when the transmission chain 11 moves, thus preventing a single tooth 311 from disengaging.

[0032] The ratchet 31 has three teeth 311 that are staggered with each other, which can simultaneously mesh with the three adjacent tooth structures 21 on the rack 2, thus dispersing backlash error through multi-tooth contact.

[0033] Furthermore, the width of the three locking teeth 311 decreases from the side closer to the hanger body 3 to the side farther away from the hanger body 3, and the height of the three locking teeth 311 also decreases sequentially from the side closer to the hanger body 3 to the side farther away from the hanger body 3, forming a gradient structure in the width and height of the locking teeth 311.

[0034] The gradient design of the height and width of the 311 clasp can accommodate the slight deformation of the rack 2, ensuring no obvious gaps during meshing, effectively avoiding displacement deviations when the hanger moves, and reducing the risk of jamming or overlapping.

[0035] As attached Figure 6 As shown, furthermore, both sides of the rack 2 are provided with intersecting horizontal and vertical reinforcing ribs 23 to enhance the overall deformation resistance of the rack 2 and reduce fracture caused by uneven stress.

[0036] Furthermore, the hanger body 3 is provided with multiple guide wheels 33, which can be made of polyurethane. When working, the guide wheels abut against the wall of the electroplating copper tank to limit the lateral displacement of the hanger body 3 and ensure smooth movement.

[0037] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
