Description

Technical Field

[0001] This utility model relates to automatic changing equipment, and more particularly to an automatic changing equipment for spring release film. Background Technology

[0002] In the modern electronics manufacturing industry, spring contacts (such as metal spring contacts or flexible circuit spring contacts) are widely used in various electronic devices to achieve functions such as electrical connection, signal transmission, or mechanical support. Spring contacts typically require a release film (also known as a protective film or peel-off film) to be applied to their surface to prevent contamination, scratches, or oxidation during transportation, storage, or processing. However, with increasing production demands and stricter process requirements, traditional manual or semi-automatic release film replacement methods can no longer meet the needs for efficient, precise, and consistent production.

[0003] What are the limitations of traditional release film replacement methods?

[0004] Manually changing release film requires a lot of manpower and is slow, making it difficult to meet the needs of large-scale production.

[0005] Insufficient precision: Manual operation makes it difficult to ensure the precise alignment of the release film and the spring sheet, which can easily lead to problems such as application misalignment, bubbles or wrinkles, affecting product quality.

[0006] Poor consistency: Due to the uncontrollability of manual operation, the changeover effect between different batches or different operators may vary greatly, resulting in a decrease in product yield.

[0007] High cost: Manual operation requires a large number of skilled workers and is prone to material waste due to operational errors, which increases production costs.

[0008] The shortcomings of existing automated equipment are reflected in:

[0009] Currently, there are some automated devices on the market for applying and peeling release films, but these devices still have the following problems in practical applications:

[0010] Limited functionality: Many devices can only perform a single function in applying or peeling off release film, and cannot achieve full-process automation.

[0011] Poor adaptability: The equipment can usually only handle springs of specific sizes or shapes, making it difficult to adapt to diverse product needs.

[0012] Insufficient precision and stability: The low precision of the drive and positioning systems of some equipment leads to unsatisfactory release film application results and poor equipment operation stability.

[0013] Complex maintenance: The equipment has a complex structure, making maintenance and debugging difficult and increasing operating costs.

[0014] To solve the above problems, there is an urgent need for an automatic spring release film changing device that can achieve full-process automation, high precision, and high stability. Utility Model Content

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] In this embodiment, an automatic release film changing device for spring sheets includes, as follows: Figure 1 The components shown are: base plate 1, spring clip gripping assembly 2, release film peeling assembly 3, spring clip conveying assembly 4, and release film changing assembly 5.

[0035] The spring clip gripping assembly 2 is mounted on the base plate 1 and is driven by a cylinder to grip the spring clips before demolding along the X and Z axes; for example Figure 1 and Figure 2The cylinder drive assembly shown includes a vertical plate 211 capable of generating driving force along the X-axis, a horizontal slide rail 212, a horizontal cylinder 213, and a horizontal slider 214. The vertical plate 211 is connected to the base plate 1. The horizontal slide rail 212 and the horizontal cylinder 213 are both mounted on the vertical plate 211 along the X-axis. The horizontal slider 214 is connected to the piston of the horizontal cylinder 213 and slidably disposed on the horizontal slider 214. The cylinder drive assembly also includes an intermediate plate 215 capable of generating driving force along the Y-axis, a vertical slide rail 216, a vertical slider 217, and a gripper 218. The intermediate plate 215 is connected to the horizontal slider 214. The vertical slide rail 216 is mounted on the intermediate plate 215 along the Z-axis. The vertical slider 217 is slidably disposed on the vertical slide rail 216. The piston of the transverse cylinder 213 drives the transverse slider 214 to slide along the transverse slide rail 212, achieving movement in the X-axis direction. The vertical slider 217 is slidably mounted on the vertical slide rail 216 and grips the spring piece via the gripper 218. Therefore, when the transverse cylinder 213 drives the transverse slider 214 to move along the X-axis, the gripper 218 can move above the spring piece. Subsequently, the vertical slider 217 moves downward along the Z-axis, and the gripper 218 grips the spring piece.

[0036] The release film peeling assembly 3 is installed at the inlet end of the spring sheet conveying assembly 4 to remove the release film from the spring sheet; the release film peeling assembly 3 includes, for example, Figure 1 The U-shaped block 31 shown and the roller 32 rotatably mounted on the U-shaped block 31 via a damping bearing are connected to the inlet end of the support slide 411. When the spring is clamped and moved to the release film peeling assembly 3, the adhesive force between the spring and the release film is overcome by the rotational peeling force of the roller 32, and the release film is peeled off from the spring.

[0037] like Figure 1 and Figure 4 As shown, the spring sheet conveying assembly 4 is mounted on the base plate 1 and conveys the demolded spring sheet unidirectionally along the X-axis via the cylinder drive assembly 2. The cylinder drive assembly 2 includes a support slide 411, a transverse slide 413, a transverse cylinder 412, and a transverse slider 414. The support slide 411, the transverse cylinder 412, and the transverse slide 413 are all arranged along the X-axis. The transverse cylinder 412 is connected to the transverse slide 413, and the transverse slider 414 is connected to the piston of the transverse cylinder 412 and slidably disposed on the transverse slide 413. The transverse slider 414 simultaneously slides within the groove of the support slide 411 to push the spring sheet unidirectionally. The piston of the transverse cylinder 412 drives the transverse slider 414 to slide along the transverse slide 413. The horizontal slider 414 slides in the groove of the bracket slide 411, pushing the spring piece to move unidirectionally along the X-axis, and conveying the spring piece from the release film peeling assembly 3 to the working area of ​​the release film changing assembly 5.

[0038] like Figure 3 As shown, the release film changing assembly 5 is mounted on the base plate 1 and located beside the spring sheet conveying assembly 4. It uses a cylinder-driven assembly 3 to adsorb the spring sheet along the Y and Z axes and move it to the release film application and cutting assembly to complete the automatic changing of the release film. The cylinder-driven assembly 3 includes a changing bracket 511, a vertical plate 3 512, a screw and nut device 513, a T-shaped plate 514, an adsorption cylinder 515, and an adsorption block 516. The changing bracket 511 is connected to the base plate 1, the vertical plate 3 512 is connected to the changing bracket 511, the screw and nut device 513 is connected to the vertical plate 3 512 along the Y-axis, and the nut of the screw and nut device 513 is connected to the adsorption cylinder 515 along the Z-axis via the T-shaped plate 514. The end of the cylinder body of the adsorption cylinder 515 is connected to the adsorption block 516 for adsorbing the spring sheet. A lead screw and nut assembly 513 is connected to the vertical plate 512 along the Y-axis. The nut of the lead screw and nut assembly 513 is connected to the adsorption cylinder 515 via a T-shaped plate 514, enabling movement along the Y-axis. The adsorption cylinder 515 is positioned along the Z-axis, with an adsorption block 516 connected to its end. The adsorption block 516 adsorbs a spring sheet under negative pressure. When the spring sheet is conveyed to the working area of ​​the release film replacement assembly 5, the adsorption block 516 moves downward along the Z-axis and adsorbs the spring sheet, then moves along the Y-axis to deliver the spring sheet to the support plate 5241 of the release film application and cutting assembly.

[0039] like Figure 3 and Figure 4 As shown, the release film application and cutting assembly includes a vertical plate 521, a release film roller 522, a release film guide assembly 523, and a cutting assembly. The vertical plate 521, the release film guide assembly 523, and the cutting assembly are all connected to the base plate 1. The release film roller 522 is rotatably connected to the vertical plate 521 for mounting the release film. The release film passes through the upper and lower positioning shafts of the release film guide assembly 523 and extends above the support plate 5241 of the cutting assembly. The adsorption block 516 can adsorb the spring sheet and move it to the support plate 5241. The support plate 5241 is connected to the support column 5131 of the release film guide assembly 523. The cutter 5242 of the cutting assembly is connected to the base plate 1 through the cutting cylinder 5243. The cutter 5242 can cut the release film from bottom to top through the reserved gap of the support plate 5241. The release film is drawn from the release film roller 522 and passes through the upper and lower positioning shafts of the release film guide assembly 523 to ensure accurate positioning. The release film extends above the support plate 5241 of the cutting assembly. The adsorption block 516 moves the spring sheet onto the support plate 5241, where the spring sheet contacts and adheres to the new release film. The cutting cylinder 5243 drives the cutter 5242 to pass through the pre-reserved gap in the support plate 5241 from bottom to top, cutting the release film to a size that matches the spring sheet.

[0040] In other embodiments, cylinder drive assembly one, cylinder drive assembly two, and cylinder drive assembly three can adopt a variety of different drive forms or structural designs to meet different application requirements or optimize equipment performance.

[0041] The cylinder-driven assembly is primarily used to grip and move the spring sheet. Alternatives may include using a servo motor to drive a ball screw or synchronous belt for precise X-axis and Z-axis movement. Alternatively, pneumatic fingers can directly grip the spring sheet, combined with a pneumatic slide to achieve X-axis and Z-axis movement. Another option is to use a hydraulic cylinder to drive the gripper for X-axis and Z-axis movement.

[0042] The cylinder drive assembly can be a motor-driven belt to transport the spring sheet along the X-axis, or a motor-driven chain to transport the spring sheet along the X-axis. Alternatively, a linear motor can be used to directly drive the slider to achieve precise transport of the spring sheet.

[0043] The cylinder drive assembly can use a servo motor to drive a ball screw or a synchronous belt to achieve precise movement of the Y and Z axes.

[0044] It should be understood that the above process relies on existing technologies such as sensors and feedback control to integrate position sensors, force sensors, etc., into each drive component to achieve closed-loop control.

[0045] The overall workflow is as follows:

[0046] Release film gripping and removal: The release film gripping assembly 2 moves along the X and Z axes via a cylinder-driven assembly 1, gripping the release film and delivering it to the release film peeling assembly 3. The release film peeling assembly 3 peels the old release film off the release film via a roller 32.

[0047] Release film conveying: After the release film is removed, the release film is conveyed by the release film conveying component 4 through the cylinder drive component 2 to move unidirectionally along the X-axis to the working area of ​​the release film changing component 5.

[0048] Release film adsorption and movement: The release film replacement assembly 5 moves along the Y and Z axes via a cylinder-driven assembly 3, adsorbs the release film and sends it to the support plate 5241 of the release film application and cutting assembly.

[0049] Release film application and cutting: The release film application and cutting assembly draws the new release film from the release film roller 522 and applies it to the spring sheet. The cutting assembly cuts the release film to a size that matches the spring sheet using the cutter 5242, completing the automatic replacement.

[0050] The automatic release film changing equipment utilizes the coordinated operation of multiple cylinder-driven components and precision mechanical structures to achieve the entire process of automatic release film removal, conveying, adsorption, application of new release film, and cutting of the release film. The core of the equipment lies in the precise coordination and efficient drive between its components, ensuring high precision and efficiency in the changing process.

[0051] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
