Description

Technical Field

[0001] The utility model relates to the technical field of flexible cable assembly, in particular to a flexible cable feeding mechanism. Background Art

[0002] Flexible cables have been widely used in various electronic products. On the flexible cable assembly production line, it is necessary to place the carrier trays filled with flexible cables on separate conveyor lines for transportation. The conveyor line for flexible cables is arranged side by side with the assembly production line.

However, the separately arranged flexible cable conveyor line not only occupies a large amount of space, but also has low transportation efficiency. On the other hand, when assembling multiple flexible cables on the same workpiece, the traditional flexible cable feeding mechanism is difficult to meet the usage requirements. Therefore, it is necessary to make a flexible cable feeding mechanism to solve the above problems. Content of the Utility Model

[0006] The tray recycling component includes a second base, a recycling conveyor belt, a second lifting component, a second lifting plate, a vertical limiting plate, a connecting block, a movable supporting block and a spring. The second base is fixed above the lower mounting plate. The recycling conveyor belt is fixed on the front and rear sides of the second base. The second lifting component is fixed on the second base and corresponds to the space between the two sets of recycling conveyor belts. The second lifting plate is fixed on the power output end of the second lifting component. The vertical limiting plate is vertically fixed above the second base. There are four groups of vertical limiting plates, which respectively correspond to the four corners of the second lifting plate. The connecting block is fixed on the second base. The movable supporting block is rotatably installed on the connecting block and corresponds to the recycling conveyor belt. The inner side of the movable supporting block is an inclined surface, and the inclined surface of the movable supporting block faces downward. The outer end of the spring is fixed on the connecting block, and the inner end is fixed on the outer side of the movable supporting block;

[0007] The feeding conveyor belt is fixedly arranged on the left side of the tray conveying component and is connected to the feeding conveyor belt.

When the wire harnesses on the tray are taken out, the transfer conveying component transports the empty tray to the return conveyor belt, and the return conveyor belt transports the tray to the tray recycling component. The empty tray is transported above the second lifting plate on the recycling conveyor belt. The second lifting component drives the second lifting plate to rise and lift the empty tray. After both ends of the empty tray contact the inclined surfaces on the movable support blocks, the movable support blocks rotate outwards, enabling the empty tray to continue to move upwards. There may already be empty trays that have returned before in the vertical limit plate. The new empty tray supports all the previous empty trays upwards. After the bottom tray is higher than the movable support blocks, the spring resets the movable support blocks and pops them inwards. Then, the second lifting component drives the second lifting plate to descend, so that all the empty trays are placed on the movable support blocks on both sides. Repeating this process, the empty trays are collected and vertically stacked. The advantages of this design are as follows: Its structure is compact, which can save production space and reduce equipment costs. Its loading efficiency is high. Moreover, when it is necessary to assemble multiple groups of wire harnesses with different specifications, multiple groups of the wire harness loading mechanisms of this design can be selected to load multiple groups of wire harnesses, making it more flexible to use.

[0017] The present utility model will be further described below with reference to the accompanying drawings:

[0018] As Figures 1 to 4 shown, a wire feeding mechanism includes a tray conveying assembly 1, a feeding conveyor belt 2, a return conveyor belt 3, a lifting driving assembly 4 and a transfer conveying component 5. The tray conveying assembly 1 includes a machine housing 11, an upper mounting plate 12, a lower mounting plate 13, a tray loading component 14 and a tray recycling component 15.

The tray loading component 14 includes a first base 141, a feeding conveyor belt 142, a first lifting component 143, a first lifting plate 144, an L-shaped limiting post 145, a bracket driving component 146 and a support bracket 147. The first base 141 is fixed above the upper mounting plate 12. The feeding conveyor belt 142 is fixed on the front and rear sides of the first base 141. The first lifting component 143 is fixed on the first base 141 and corresponds to the space between two groups of feeding conveyor belts 142. The first lifting plate 144 is fixed on the power output end of the first lifting component 143. The L-shaped limiting post 145 is vertically fixed above the first base 141. Four groups of L-shaped limiting posts 145 are provided and respectively correspond to the four corners of the first lifting plate 144. The bracket driving component 146 is fixed on the first base 141. The support bracket 147 is fixed on the power output end of the bracket driving component 146 and corresponds to the upper side of the feeding conveyor belt 142;

[0019] The tray recycling component 15 includes a second base 151, a recycling conveyor belt 152, a second lifting component 153, a second lifting plate 154, a vertical limiting plate 155, a connecting block 156, a movable supporting block 157, and a spring 158. The second base 151 is fixed above the lower mounting plate 13. The recycling conveyor belt 152 is fixed on the front and rear sides of the second base 151. The second lifting component 153 is fixed on the second base 151 and corresponds to the space between the two groups of recycling conveyor belts 152. The second lifting plate 154 is fixed on the power output end of the second lifting component 153. The vertical limiting plate 155 is vertically fixed above the second base 151. There are four groups of vertical limiting plates 155, which respectively correspond to the four corners of the second lifting plate 154. The connecting block 156 is fixed on the second base 151. The movable supporting block 157 is rotatably mounted on the connecting block 156. The movable supporting block 157 corresponds to the recycling conveyor belt 152. The inner side of the movable supporting block 157 is an inclined surface, and the inclined surface of the movable supporting block 157 faces downward. The outer end of the spring 158 is fixed on the connecting block 156, and the inner end is fixed on the outer side of the movable supporting block 157;

[0020] The feeding conveyor belt 2 is fixedly arranged on the left side of the tray conveying assembly 1 and is connected to the feeding conveyor belt 142. The return conveyor belt 3 is fixedly arranged on the left side of the tray conveying assembly 1 and is connected to the recycling conveyor belt 152. The lifting drive assembly 4 is fixedly arranged on the left side of the feeding conveyor belt 2. The transfer conveying component 5 is fixed on the power output end of the lifting drive assembly 4.

[0021] After the trays loaded with flexible cables are vertically stacked and placed in the rectangular area formed by four groups of L-shaped limit posts 145, the bottom tray is placed on the first lifting plate 144. When a group of trays needs to be conveyed, the first lifting component 143 first drives the first lifting plate 144 to descend by the distance of one layer of trays, so that the second-bottom tray corresponds to the support bracket 147. The bracket driving component 146 drives the support bracket 147 to extend and holds the second-bottom tray. Then, the first lifting component 143 drives the first lifting plate 144 to descend, and the bottom tray falls onto the feeding conveyor belt 142 and is transported to the loading conveyor belt 2. The loading conveyor belt 2 continues to transport the tray to the transfer conveying component 5. The picking manipulator grabs the flexible cables on the tray and is used for subsequent assembly. When the flexible cables on the tray are picked up, the transfer conveying component 5 transports the empty tray to the return conveyor belt 3, and the return conveyor belt 3 transports the tray to the tray recycling component 15. The empty tray is transported on the recycling conveyor belt 152 to above the second lifting plate 154. The second lifting component 153 drives the second lifting plate 154 to rise and holds up the empty tray. After the two ends of the empty tray contact the inclined surfaces on the movable supporting blocks 157, the movable supporting blocks 157 rotate outwards, enabling the empty tray to continue to move upwards. There may already be empty trays that have been returned before in the vertical limiting plate 155. The new empty tray supports all the previous empty trays upwards. After the bottom tray is higher than the movable supporting blocks 157, the spring 158 causes the movable supporting blocks 157 to reset and pop inwards. Then, the second lifting component 153 drives the second lifting plate 154 to descend, placing all the empty trays on the movable supporting blocks 157 on both sides. This process is repeated to collect and vertically stack the empty trays. The advantages of this design are as follows: It has a compact structure, can save production space and reduce equipment costs, has a high loading efficiency. Moreover, when multiple groups of flexible cables of different specifications need to be assembled, multiple sets of the flexible cable loading mechanisms of this design can be selected to load multiple groups of flexible cables, making it more flexible to use.

[0022] The transfer conveying component 5 includes a mounting base 51, a transfer conveyor belt 52, a third lifting component, a third lifting plate, a top supporting plate 53, a clamping driving component 54, and clamping plates 55. The mounting base 51 is fixed to the power output end of the lifting driving assembly 4. The transfer conveyor belt 52 is fixed to the front and back sides of the mounting base 51. The third lifting component is fixed on the mounting base 51 and corresponds to the space between the two groups of transfer conveyor belts 52. The third lifting plate is fixed to the power output end of the third lifting component. The top supporting plate 53 is erected above the third lifting plate. The clamping driving component 54 is fixed on the third lifting plate and corresponds to the lower side of the top supporting plate 53. The clamping plates 55 are fixed to the power output end of the clamping driving component 54. One set of clamping plates 55 is provided on each of the left and right sides of the clamping driving component 54, and the two sets of clamping plates 55 respectively correspond to the left and right sides of the top supporting plate 53.

[0023] After the carrier tray with the flexible cable is transported from the loading conveyor belt 2 to the transfer conveyor belt 52, the third lifting component drives the third lifting plate to rise, so that the top support plate 53 lifts the carrier tray and separates it from the transfer conveyor belt 52. Then, the clamping drive component 54 drives the clamping plate 55 to clamp the carrier tray. Subsequently, the picking manipulator grabs the flexible cable on the carrier tray and assembles it. When all the flexible cables on the carrier tray are picked, the lifting drive assembly 4 drives the transfer conveying component 5 to descend and the transfer conveyor belt 52 conveys in the reverse direction. Then, the clamping drive component 54 drives the clamping plate 55 to reset, and the third lifting component places the empty carrier tray on the transfer conveyor belt 52, and the transfer conveyor belt 52 conveys the empty carrier tray to the return conveyor belt 3.

[0024] Above the movable supporting block 157, there is a wedge-shaped block 1571 protruding upward. The inner side of the wedge-shaped block 1571 is an inclined surface, and the inclined surface of the wedge-shaped block 1571 faces upward.

[0025] When the new empty carrier tray lifts all the empty carrier trays in between and then lands on the movable supporting block 157, the inclined surface on the wedge-shaped block 1571 guides the bottommost empty carrier tray, making its landing position on the movable supporting block 157 more accurate and facilitating the subsequent neat and vertical stacking of the empty carrier trays.

[0026] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
