Description

Technical Field

[0001] The invention belongs to the field of fuel cell production equipment, in particular to a five-in-one automatic back film peeling mechanism for a fuel cell. Background Art

[0002] One of the core processes in the fuel cell industry is the preparation process from membrane electrode to seven-in-one. An important step is to tear off the protective film on the five-in-one incoming product before the GDL bonding operation can be carried out.

[0003] There is currently no automated mechanism on the market specifically for tearing off the five-in-one back film of fuel cells. The current back film tearing mechanisms on the market are all for hard products, such as the semiconductor industry, lithium battery industry, etc., and their product characteristics are all hard. There is no automated method for tearing off the back film specifically for soft materials such as multi-layer films. Its traditional film tearing method is not suitable for tearing off the film between soft multi-layer films, and the adhered products and the back film will be torn off and thrown away together. The membrane electrode five-in-one material is a structure with multiple layers of soft films stacked together.

[0004] At present, the process of five-in-one lamination and front back film removal is to tear the film manually. A small gap is peeled off the edge of the film manually and then the back film is torn off by pulling hard. In the process of manual corner peeling, the corners need to be bent, which can easily deform the product and damage the film. The current manual method is inefficient and requires extremely high worker proficiency, which hinders the development of large-scale production in the industry. Therefore, it is urgent to develop an automatic mechanism to replace manual labor for five-in-one back film peeling. Summary of the invention

[0005] In order to solve the above problems, a five-in-one automatic back film tearing mechanism for fuel cells is proposed, which replaces the complex process that originally required manual operation by skilled workers with an automated mechanism to achieve automated production.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A five-in-one automatic back film peeling mechanism for a fuel cell, comprising: A first plane moving mechanism having a first moving terminal, wherein the moving range of the first moving terminal is a first vertical plane; A tear-off film suction cup device is installed on the first mobile terminal, and the suction surface of the tear-off film suction cup device faces downward; A film-shaft-tearing device, comprising a second mobile terminal, wherein the moving direction of the second mobile terminal is a first direction, and the first direction is perpendicular to the first vertical plane; The film tearing head device is installed on the second mobile terminal, and the film tearing head device and the film tearing sucker device can be driven to be vertically opposite to each other.

[0007] Preferably, the fuel cell five-in-one automatic back film peeling mechanism also includes A second plane moving mechanism having a third moving terminal, wherein the moving range of the third moving terminal is a second vertical plane; A film tearing suction cup device is installed on the third mobile terminal, and the suction surface of the film tearing suction cup device faces upward; A film-tearing shaft device, comprising a fourth mobile terminal, wherein the moving direction of the fourth mobile terminal is a second direction, and the second direction is perpendicular to the second vertical plane; The film tearing head device is installed on the fourth mobile terminal, and the film tearing head device and the film tearing suction cup device can be driven vertically opposite to each other.

[0008] Preferably, the tear-off film suction cup device and the tear-off film suction cup device can be moved to relative positions on the suction surface.

[0009] Preferably, the tear-off film suction cup device and the tear-off film suction cup device both comprise a suction cup body, and an array of suction holes consisting of a plurality of suction holes is provided on the suction surface of the suction cup body.

[0010] Preferably, a reinforced suction hole is provided at a corner corresponding to the suction surface of the suction cup body, and the diameter of the reinforced suction hole is larger than the diameter of the suction hole to increase the suction force at the corner.

[0011] Preferably, the film head tearing-off device and the film head tearing-off device are both composed of a film reeling and unreeling mechanism, a film tearing pressure wheel, a waste discharge mechanism and a sensor.

[0012] Preferably, the fuel cell five-in-one automatic back film peeling mechanism also includes an automatic loading bin.

The double-sided back tearing effect can be achieved through this mechanism. The advantage of the present invention is that it fills the market gap and meets the needs of large-scale production in the fuel cell industry. The complex process that originally required skilled workers to operate manually is replaced by an automated mechanism, which greatly improves work efficiency and yield rate, and makes the demand for expanding production capacity no longer restricted by the number of skilled workers. It is especially suitable for the automated method of tearing the back film of soft materials such as multi-layer films. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in combination with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0020] In order to solve the problem that the product may be deformed and the film may be damaged by bending the corners during the manual stripping process, Figure 1 As shown, this embodiment proposes a five-in-one automatic back film peeling mechanism for a fuel cell, including an automatic loading bin 1, a frame is set at the bottom of the automatic loading bin 1 to keep the automatic loading bin 1 at a suitable height, and the automatic loading bin 1 includes a servo lifting electric cylinder and a positioning frame. The bottom of the positioning frame has a supporting plate structure, and a hollow is opened in the middle of the plate structure. The extended end of the servo lifting electric cylinder is set upward, and the extended end of the servo lifting electric cylinder is connected to the lifting structure. Part of the lifting structure passes through the hollow of the plate structure. There are multiple materials to be processed stacked inside the positioning frame, so the servo lifting electric cylinder can drive the lifting structure to push up multiple materials to be processed step by step.

[0021] In the first action mechanism, a gantry frame is provided near the automatic loading bin 1, and a tear-off film X-axis device 2 is installed on the top of the gantry frame. The lateral guide portion of the tear-off film X-axis device 2 is provided horizontally, and the power end of the tear-off film X-axis device 2 is fixed to the external power supply device through a drag chain protection. A slider is installed on the guide portion of the tear-off film X-axis device 2, and the back of the tear-off film Z-axis device 3 is connected to the guide block, and a slider is installed on the front of the tear-off film Z-axis device 3. The tear-off film X-axis device 2 and the tear-off film Z-axis device 3 together constitute a first plane moving mechanism, and the slider of the tear-off film Z-axis device 3 serves as a first moving terminal, and the moving range of the first moving terminal is a first vertical plane.

[0022] A tear-off film suction cup device 4 is installed at the lower end of the first mobile terminal. The structure of the tear-off film suction cup device 4 is as follows: Figure 2 As shown, the main body of the film tearing suction cup device 4 is a suction cup body 41, the lower side surface of the suction cup body 41 is a plane, and an array suction hole 42 consisting of a plurality of suction holes is provided on the plane. A reinforcement suction hole 43 is provided at a corner corresponding to the suction surface of the suction cup body 41, and the diameter of the reinforcement suction hole 43 is larger than the diameter of the suction hole to increase the suction force at the corner.

[0023] A film tearing Y-axis device 6 is provided below the above-mentioned door frame. The guide portion of the film tearing Y-axis device 6 is a linear guide structure, and its direction is perpendicular to the first vertical plane. A film tearing head device 5 is provided on the slider of the film tearing Y-axis device 6. The film tearing head device 5 in this embodiment is composed of a film winding and unwinding mechanism, a film tearing pinch wheel, a waste discharge mechanism and a sensor. The function of the film tearing head device 5 is to tear off the lower back film material.

[0024] The above-mentioned fuel cell five-in-one automatic back film tearing mechanism can be operated according to a predetermined control program to complete the action of tearing off the back side of the material. Specifically, a stack of materials (three hundred pieces) is manually placed into the automatic loading bin 1 at one time, and the automatic loading bin 1 lifts the materials to the designated position and stops, and the tear-off film X-axis device 2 and the tear-off film Z-axis device 3 drive the tear-off film suction cup device 4 to the automatic loading bin 1 to absorb the materials. Then the tear-off film X-axis device 2 and the tear-off film Z-axis device 3 drive the tear-off film suction cup device 4 to move to the tear-off film head device 5 The tear-off film head device 5 rises to press the tear-off film pressure wheel and the film roll at the corner of the material. In the next step, the tear-off film head device 5 presses the five-in-one material under the joint action of the tear-off film X-axis device 2 and the tear-off film Y-axis device 6 to roll with XY interpolation, and the tear-off film pressure wheel and the reeling and unwinding mechanism work together to stick a corner of the lower back film of the five-in-one material. Then, the lower back film is torn off as a whole under the joint movement of the tearing film X-axis device 2, the tearing film Z-axis device 3, and the tearing film Y-axis device 6, and then the waste discharge mechanism of the tearing film head device 5 discharges and discards the torn lower back film.

[0025] The above-mentioned fuel cell five-in-one automatic back film tearing mechanism can be operated according to a predetermined control program to complete the action of tearing off the back film on one side of the material. In this embodiment, the second action mechanism is used to complete the action of tearing off the back film on the other side of the material.

[0026] In other embodiments, an independent additional mechanism may be used as a backup. For example, after the back film on one side of the material is torn off, the material may be flipped over by the additional mechanism to complete the tearing off of the back film on the other side.

[0027] In order to improve the efficiency of the film-tearing action of the mechanism, in this embodiment, a second action mechanism is used to complete the action of tearing off the back film on the other side of the material.

[0028] Specifically, the present embodiment proposes a film-on sucker device, a film-on X-axis device 8, a film-on Y-axis device 9, a film-on Z-axis device 10, and a film-on head device 11. The film-on Y-axis device 9 and the film-on Z-axis device 10 form a second plane moving mechanism, and the film-on sucker device 7 is installed at the action end of the second plane moving mechanism. The film-on sucker device 7 is installed at the action end of the film-on X-axis device 8.

[0029] The action principle of the second action mechanism is similar to that of the first action mechanism, except that the film tearing head device 11 of the second action mechanism is installed on the action end of the second plane moving mechanism, and the film tearing suction cup device 7 is installed on the slider of the film tearing X-axis device 8. The advantage of this arrangement is that it can avoid interference between the first action mechanism and the second action mechanism to a certain extent, and the material can be transferred and connected between the first action mechanism and the second action mechanism.

[0030] In this embodiment, since the structures of the tear-off film suction cup device 4 and the tear-off film suction cup device 7 are consistent, and the structures of the tear-off film head device 5 and the tear-off film head device 11 are consistent, they are not described in detail.

[0031] In this embodiment, the material after tearing off the lower film is driven to the receiving position of the tearing film suction cup device 7 by the tearing film X-axis device 2, the tearing film Z-axis device 3, and the tearing film suction cup device 4, and the film is transferred to the tearing film suction cup device 7 for adsorption. The tearing film suction cup device 7 carries the five-in-one material to be torn off and runs to the tearing film initial position below the tearing film head device 11. The tearing film Z-axis device 10 brings the tearing film head device 11 down to press the tearing film pressure wheel and the film roll on the corner of the material. In the next step, the tearing film head device 11 presses the five-in-one material under the joint action of the tearing film X-axis device 8 and the tearing film Y-axis device 9 to roll with XY interpolation, and the tearing film pressure wheel and the reeling and unwinding mechanism cooperate to stick a corner of the upper back film of the five-in-one material. Then, the lower back film is torn off as a whole under the joint movement of the tearing film X-axis device 8, the tearing film Y-axis device 9, and the tearing film Z-axis device 10, and then the waste discharge mechanism of the tearing film head device 11 discharges and discards the torn upper back film.

[0032] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
