Description

Technical Field

[0001] The utility model relates to a rack conveying device of electroplating equipment, in particular to a buckle transmission device of the rack conveying equipment. Background Art

[0002] In PCB electroplating production lines, chains are generally used to transport hangers. The driving principle is to set a sharp-toothed buckle on the hanger. After the sharp-toothed buckle is engaged with the sharp teeth on the chain, the hanger is driven forward while the chain is running. In actual applications, because the chain is thin and prone to spatial displacement, it often shakes during the transportation of the hanger. This shaking effect will cause uneven electroplating of the PCB, thereby affecting the electroplating quality. Utility Model Content

[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions.

[0005] A clip transmission device for a hanger conveying equipment includes a main frame, a steel belt and a driving wheel group for driving the steel belt to move forward, a slide rail is fixed on the main frame, the slide rail is arranged parallel to the adjacent part of the steel belt, a plurality of hangers are overlapped on the slide rail, and the hangers slide in cooperation with the slide rail, a plurality of transmission blocks distributed in sequence along the front and rear directions are fixed on the surface of the steel belt, the top of the transmission block is evenly distributed with teeth arranged in sequence along the front and rear directions, at least one inverted tooth carrier block is fixed on the hanger, and a plurality of oblique clips inclined rearward and downward are evenly distributed on the inverted tooth carrier block, and the oblique clips are clipped in cooperation with the teeth.

[0006] Preferably, the transmission block is fixed to a position of the steel belt close to the edge by screws.

[0007] Preferably, a spacer is provided between the transmission block and the steel belt.

[0008] Preferably, the hanging bracket includes a hanging plate bent in a "Z" shape, a transverse support plate is fixed to the upper end of the hanging plate, and the inverted tooth support block is fixed on the transverse support plate.

When the hanger is hung on the slide rail, the oblique clip on the inverted tooth carrier block is directly engaged with the teeth on the transmission block. Based on the matching relationship between the teeth and the oblique clip, the hanger can be driven to move forward straightly while the steel belt moves, and because the steel belt has a certain width and will not shift left and right, the transmission cooperation between the hanger and the steel belt is more reliable.

[0017] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model discloses a buckle transmission device for a rack conveying device, combined with Figures 1 to 4 As shown, it includes a main frame 1, on which a steel belt 2 and a driving wheel group 3 for driving the steel belt 2 to move forward are provided. A slide rail 4 is fixed on the main frame 1, and the slide rail 4 is arranged parallel to the adjacent part of the steel belt 2. A plurality of hangers 5 are overlapped on the slide rail 4, and the hangers 5 slide in cooperation with the slide rail 4. A plurality of transmission blocks 6 distributed in sequence along the front and rear directions are fixed on the surface of the steel belt 2, and the top of the transmission block 6 is evenly distributed with teeth 60 arranged in sequence along the front and rear directions. At least one inverted tooth carrier block 50 is fixed on the hanger 5, and a plurality of oblique buckles 51 inclined rearward and downward are evenly distributed on the inverted tooth carrier block 50, and the oblique buckles 51 are snap-fitted with the teeth 60.

[0019] In the above structure, a preset motor or other driving mechanism is used to drive the driving wheel group 3 to operate, and then the driving wheel group 3 is used to drive the steel belt 2 of a preset width to operate forward. When the hanger 5 is hung on the slide rail 4, the oblique buckle 51 on the inverted tooth carrier block 50 is directly engaged with the teeth 60 on the transmission block 6. Based on the matching relationship between the teeth 60 and the oblique buckle 51, the hanger 5 can be driven to move forward straightly while the steel belt 2 moves. Moreover, since the steel belt 2 has a certain width and will not shift left and right, the transmission cooperation between the hanger 5 and the steel belt 2 is more reliable. Compared with the existing technology, the utility model not only realizes smooth transportation, but also avoids adverse transportation conditions such as tooth jumping, and has better transmission performance.

[0020] In order to facilitate accurate engagement with the hanger 5, in this embodiment, the transmission block 6 is fixed to the position near the edge of the steel belt 2 by screws. In order to make the inverted tooth bearing block 50 extend above the steel belt 2, in this embodiment, see Figure 3 The upper end of the hanger 5 has a laterally extending support block 56 , and the inverted tooth support block 50 is fixed to the end of the support block 56 .

[0021] See Figure 2 In this embodiment, a spacer 61 is provided between the transmission block 6 and the steel belt 2. The spacer 61 can be a component such as a plastic block that can achieve a tight fit.

[0022] For the specific structure of the hanger 5, please refer to Figure 3 The hanger 5 includes a Z-shaped hanging plate 52, with a transverse support plate 53 fixed to the upper end of the hanging plate 52. The inverted tooth support block 50 is fixed to the transverse support plate 53. In the above structure, the Z-shaped hanging plate 52 facilitates the inverted tooth support block 50 and the oblique buckle 51 to extend as far as possible above the steel belt 2. Accordingly, the PCB board loaded on the lower end of the hanger 5 extends as far as possible away from the main frame 1, thereby avoiding positional interference between the hanger 5 and other adjacent structures.

[0023] As a preferred embodiment, two inverted tooth bearing blocks 50 are fixed on the transverse support plate 53. In this embodiment, by providing two side-by-side inverted tooth bearing blocks 50, the transmission reliability between the hanger 5 and the steel belt 2 is improved.

[0024] Regarding the preferred sliding fit between the hanger 5 and the slide rail 4, in this embodiment, a buckle groove 54 is provided on the hanger plate 52 outside the transverse support plate 53, and the buckle groove 54 is buckled on the slide rail 4 and the two are slidably fitted.

[0025] In order to facilitate loading of PCB boards, in this embodiment, a transverse carrier 55 is fixed to the lower end of the hanging plate 52. In actual application, a preset PCB board clamping fixture needs to be installed on the transverse carrier 55.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
