Combined with the drive of a motor and a pneumatic dispensing device, it ensures that the dispensing needle always dispenses adhesive in line with the helical surface, and the flexible double-helix stacked layer is supported by a smooth support rod.
It achieves efficient dispensing of flexible double-helix stacked workpieces, ensuring uniform distribution of adhesive dots or lines on the helical surface, stable support of interlayer gaps, and bonding after curing of the adhesive film. It is suitable for emerging fields such as electro-hydraulic artificial muscles.

However, the application is not necessarily limited by such disclosed embodiments; but can be practiced or carried out in various ways. The skilled person will readily appreciate that certain features known in the art may, of course, be employed in the practice of the present application without use of the presenting description.
[0018] In Figure 1 , Figure 2 , Figure 3In the shown embodiment, the screw rod group of the left and right screw rod slide table 01 is composed of the left-hand screw rod 02a and the right-hand screw rod 02b, which is driven to rotate by the motor 03, and the left-hand screw rod 02a and the right-hand screw rod 02b are rigidly connected and the rotation axes coincide; the outer wall threads of the left-hand screw rod 02a and the right-hand screw rod 02b are connected with the sliding blocks 04a and 04b respectively, and when the motor 03 drives the screw rod group to rotate, the sliding blocks 04a and 04b connected with the left-hand screw rod 02a and the right-hand screw rod 02b move approximately towards or away from each other; the sliding blocks 04a and 04b are connected with the glue dispensing cylinders 05a and 05b respectively, and the glue dispensing cylinders 05a and 05b are driven by the motor and / or the pneumatic glue pushing device to dispense glue; the vertical slide tables 07a and 07b driven by the motors 06a and 06b are screw rod slides, and are respectively provided with the sliding blocks 08a and 08b, which are connected with the left and right screw rod slide table 01 to drive the left and right screw rod slide table 01 to move in the approximately vertical direction; the rotary clamp 09 is fixed on the motor 10, and the rotation axis thereof is approximately parallel to the movement plane of the sliding blocks 08a and 08b, and is used to clamp the flexible double helical stacked workpiece; the flexible double helical stacked workpiece comprises the terminal 201 and the flexible double helical stacked layers 202a and 202b connected with the terminal 201, and the flexible double helical stacked layers 202a and 202b are helically and alternately stacked and configured to reserve an axial through hole in the axial direction; the glue dispensing needle heads 11a and 11b are respectively connected with the glue dispensing orifices of the glue dispensing cylinders 05a and 05b, and the connecting lines of the needle tips of the glue dispensing needle heads 11a and 11b are approximately parallel to the rotation axis of the screw rod group of the left and right screw rod slide table 01, and the collision point of the needle tips is always approximately located near the rotation axis of the rotary clamp 09; the glue dispensing needle heads 11a and 11b are always partially inserted into the interlayer gap of the flexible double helical stacked layers after the glue dispensing starts, and each glue dispensing needle head always dispenses glue to one helical surface of the flexible double helical stacked layers. Figure 3 As shown, the glue dispensing needle head 11a corresponds to the flexible helix 202b, and the glue dispensing needle head 11b corresponds to the flexible helix 202a; the axes of the glue dispensing needle heads 11a and 11b form an angle with the horizontal plane, which is greater than or equal to 0° and less than or equal to 60°, and the function thereof is to support the interlayer gap of the flexible double helical stacked layers while dispensing glue. Figure 2 In the given embodiment, the clamping mode of the smooth support rod 12 is that the smooth support rod 12 penetrates the through hole screw 23 fixed on the through hole of the cantilever 13, and is clamped by the three-jaw chuck 22 connected with the through hole screw 23; the smooth support rod 12 penetrates the axial through hole of the flexible double helical stacked layers to the terminal 201, and is approximately coincident with the rotation axis of the rotary clamp 09, and is used to support the flexible double helical stacked layers.
[0019] When dispensing cartridges 05a and 05b contain two-component adhesive, a needle-type stop valve is connected between the two dispensing needles and the dispensing nozzle of the dispensing cartridge to prevent adhesive overflow.
[0020] Figure 3 The document describes a possible dispensing method. Under the control of an external controller, such as a PLC, dispensing needles 11a and 11b apply a glue dot to their respective flexible spiral layers. Then, driven by a left and right rotary screw slide, they move linearly in opposite directions for a certain distance and apply a second glue dot. Subsequently, driven by 08a and 08b, the left and right rotary screw slide 01 moves upward a certain distance. At the same time, the rotary fixture 09 rotates counterclockwise by 90+n° or 180+n°, where 0° < n < 90°. After this, dispensing needles 11a and 11b repeat the above dispensing process until they reach the top of the flexible double spiral stacked layer and then withdraw from the interlayer gap of the flexible double spiral stacked layer.
[0021] Figure 4 Another possible dispensing method is presented. (Compared to...) Figure 3 The difference in the dispensing process is that, while dispensing needles 11a and 11b begin dispensing glue on their respective flexible spiral layers, they move linearly in opposite directions for a certain distance under the drive of the left and right rotating screw slides before stopping dispensing glue, thus achieving linear dispensing.
[0022] Obviously, Figure 3 , Figure 4 The dispensing methods can be used in combination to achieve single-point and / or linear multi-point and / or line dispensing.
[0023] Figure 5 An embodiment is presented that uses separate vertical lead screw slides 01a and 01b to replace the left-right rotating lead screw slide 01. In this embodiment, the lead screw slides 01a and 01b are configured at a certain angle, and the dispensing logic is not fundamentally different from the above scheme, so it will not be described in detail here.
[0024] Figure 6 The dispensing effect of the present invention in the foregoing embodiments is presented. Taking the rotating fixture rotating counterclockwise by 180+n° each time during the dispensing process as an example, after the dispensing is completed, the flexible double-helix stacked layer is compacted. After the adhesive cures into a film, the interlayer adhesive film achieves interlayer bonding of adjacent flexible helical layers, and the arrangement of adhesive dots or lines is a double helix ascending. At this time, the flexible double-helix stacked layer still exhibits the effect after rotating 180° around the axis of the through hole. Figure 6 The dispensing effect in [the process]. In [the context of] the dispensing effect. Figure 6In the illustrated embodiment, the flexible double-helix stacked layer is a flexible electrode wrapped with a flexible insulating outer layer. The dispensing effect shown allows the entire structure to retain a certain degree of looseness while avoiding excessively large interlayer spacing, which can be applied to emerging fields such as electro-hydraulic artificial muscles.
