Description

Technical Field

[0001] The present application relates to the field of automobile product production, and in particular to a workpiece conveying device for an automobile heating pad wiring assembly line. Background Art

[0002] A car heating pad is a seat cushion that heats the car seat so that people do not feel cold when driving.

[0003] Car heating pads use electricity for heating, so they consist of a flexible heating element and two wires. In the heating pad production line, the ends of the two wires are placed close together and side by side. Each wire end is secured by soldering, followed by resistance testing, and finally, an insulating protective sheath is wrapped around the wire ends using heat shrink technology.

[0004] The above-mentioned multiple processes correspond to multiple workstations of the assembly line, that is, the heating pad and the wire need to pass through multiple workstations in sequence for different processing. Since the heating pad and the wire are flexible and have low posture stability, they need to be repositioned every time they arrive at a workstation for processing. The operating efficiency is low and positioning deviations are prone to occur. Utility Model Content

[0005] In order to improve the above problems, the present application provides a workpiece conveying device for an automobile heating pad wiring assembly line.

[0006] The present application provides a workpiece conveying device for a wiring assembly line of an automobile heating pad, which adopts the following technical solutions:

[0007] A workpiece conveying device for an automobile heating pad wiring assembly line includes a frame, a plurality of processing stations are provided on the frame, an electric slide and a conveying fixture are provided on the frame, the conveying fixture is arranged on the slider of the electric slide, and the slider of the electric slide passes through each processing station in sequence when sliding, and the conveying fixture clamps the wire.

[0008] By adopting the above technical solution, the conveying fixture clamps the wire and passes it through each processing station for corresponding processing. The initial posture of the wire on the conveying fixture is consistent with that of each station, and there is no need to manually straighten the wire multiple times, thereby improving processing efficiency and positioning accuracy.

[0009] Preferably, the conveying fixture includes a base seat, a lower clamping block and an upper clamping block. The base seat is fixedly connected to the slider of the electric slide. A clamping drive component is provided on the base seat. The clamping drive component is used to control the upper clamping block and the lower clamping block to move closer to or away from each other. The upper clamping block and the lower clamping block respectively abut the opposite sides of the wire.

[0010] By adopting the above technical solution, the upper clamping block and the lower clamping block approach each other and clamp the wire to "fix" the wire, and the two clamping blocks move away from each other to release the wire.

[0011] Preferably, the clamping drive assembly includes a drive cylinder, the drive cylinder is fixedly connected to the base seat, and the lower clamping block is fixedly connected to the piston rod of the drive cylinder.

[0012] By adopting the above technical solution, the operation of the driving cylinder is used to control the directional reciprocating movement of the lower clamping block.

[0013] Preferably, two synchronization rods are provided on the base seat, one end of the synchronization rod is hinged to the base seat, and the other end is hinged to the upper clamping block, and the two synchronization rods are equal in length and their length directions are parallel to each other.

[0014] By adopting the above technical solution, the upper clamping block forms a parallelogram mechanism based on the base block through two synchronous rods. The upper clamping block swings relative to the base seat through the parallelogram mechanism, and its own posture remains unchanged during the swing.

[0015] Preferably, a clamp control rod is hinged on the lower clamping block, and the clamp control rod is hinged to one of the synchronization rods at the same time, and the axes of the hinge axis on the clamp control rod and the hinge axis on the synchronization rod are parallel to each other.

[0016] By adopting the above technical solution, when the piston rod of the driving cylinder is extended and retracted, the lower clamping block applies torque to the synchronous rod through the clamp control rod to rotate it, thereby causing the upper clamping block to swing relative to the base.

[0017] Preferably, the lower clamp block is provided with a plurality of clamp slots for the wires to pass through.

[0018] By adopting the above technical solution, the fixture slot positions each wire, so that the relative positions between the wires can be determined.

[0019] Preferably, the lower clamping block is fixedly connected to two extension plates on one side facing the upper clamping block, the clamp slot is provided on the extension plates, and the upper clamping block enters the space between the two extension plates when moving close to the lower clamping block.

[0020] By adopting the above technical solution, since the upper clamping block enters the space between the two extension plates when moving closer to the lower clamping block, that is, the lower edge of the upper clamping block is located within the depth range of the clamp groove, the wire is not easy to fall out of the clamp groove.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Through the setting of the transfer fixture, the transfer fixture clamps the wire and passes it through each processing station for corresponding processing. The initial posture of the wire on the transfer fixture is consistent at each station, eliminating the need for manual straightening of the wire multiple times, thereby improving processing efficiency and positioning accuracy;

[0023] 2. Through the setting of the synchronization rod and the clamp control rod, a parallelogram drive mechanism is formed between the upper clamping block and the base. When the lower clamping block moves, the clamp control rod is used to control the rotation of the synchronization rod, and the upper clamping block can move closer to or away from the lower clamping block to achieve the clamping function of the wire.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a workpiece conveying device for a wiring assembly line of an automobile heating pad, such as Figure 1 and 2 As shown, the machine comprises a frame 1 on which are arranged a plurality of processing stations, each of which sequentially performs terminal application, wire 3 pre-positioning, terminal welding, resistance testing, insulation tube application, and heat shrinkage on the wires 3. The frame 1 is provided with an electric slide 11 and a transfer fixture 2. The electric slide 11 is fixedly connected to the frame 1. The transfer fixture 2 is mounted on a slider of the electric slide 11. The slider's sliding range extends from the wire 3 pre-positioning station to the insulation tube application station. The transfer fixture 2 is used to clamp and secure the two wires 3 of the heating pad during this process.

[0030] like Figure 2As shown, the conveying fixture 2 includes a base 21, a lower clamping block 23, an upper clamping block 22, and a clamping drive assembly 24. The base 21 is fixedly connected to the slider of the electric slide 11. The lower clamping block 23 and the upper clamping block 22 are respectively movable relative to the base 21. The clamping drive assembly 24 is used to control the upper clamping block 22 and the lower clamping block 23 to move closer to or away from each other. The clamping drive assembly 24 includes a driving cylinder 241, which is fixedly connected to the base 21. The direction of extension and contraction of the piston rod of the driving cylinder 241 is vertical. The lower clamping block 23 is fixedly connected to the piston rod of the driving cylinder 241, that is, the lower clamping block 23 moves in an upward and downward manner.

[0031] like Figure 2 and 3 As shown, two synchronization rods 242 are provided on the top of the base 21. One end of the synchronization rod 242 is hinged to the base 21, and the other end is hinged to the upper clamping block 22. The two synchronization rods 242 are equal in length and parallel in length. Thus, the upper clamping block 22, through the two synchronization rods 242, forms a parallelogram structure based on the base. The upper clamping block 22 is long and its length is always horizontal. A clamp control rod 243 is hinged to the lower clamping block 23. The clamp control rod 243 is also hinged to one of the synchronization rods 242. The axes of the hinges on the clamp control rod 243 and the hinge axes on the synchronization rods 242 are parallel to each other, and their axes are both horizontal and perpendicular to the length of the upper clamping block 22. When the piston rod of the driving cylinder 241 is extended or retracted, the lower clamping block 23 applies torque to the synchronization rod 242 through the clamp control rod 243, causing it to rotate, causing the upper clamping block 22 to swing relative to the base 21. When the piston rod of the driving cylinder 241 extends upward, the lower clamping block 23 and the upper clamping block 22 approach each other, and the two wires 3 are located therebetween.

[0032] like Figure 2 and 3 As shown, the lower clamping block 23 is integrally formed with two extension plates 231 on one side facing the upper clamping block 22. The plate surface of the extension plate 231 is perpendicular to the hinge axis of the synchronization rod 242. A plurality of clamp grooves 232 are provided on the extension plate 231. When the upper clamping block 22 and the lower clamping block 23 clamp the wire 3 up and down, the clamp groove 232 allows the wire 3 to pass through, thereby determining the relative positions of the two wires 3; when the upper clamping block 22 moves close to the lower clamping block 23, it enters the space between the two extension plates 231, that is, the lower edge of the upper clamping block 22 is located within the depth range of the clamp groove 232, and the wire 3 is not easy to escape from the clamp groove 232.

[0033] The implementation principle of the workpiece conveying device of the automobile heating pad wiring assembly line in the embodiment of the present application is as follows:

[0034] The wire 3 is placed between the upper clamping block 22 and the lower clamping block 23, and then the upper clamping block 22 and the lower clamping block 23 are driven to move closer to each other by the clamping drive component 24. The two together form a clamping contact on the two wires 3. When the slider of the electric slide 11 passes through each workstation, the equipment at each workstation processes the end of the wire 3. During this period, the clamping state of the conveying fixture 2 on the wire 3 remains unchanged.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
