Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, and more particularly to a film strip processing device. Background Technology

[0002] To prevent localized stress on the edges of the cells caused by the solder ribbons during the lamination of battery string modules, which could lead to microcracks in the cells, such as... Figure 13 As shown, during the battery string production process, film strips 200 need to be pasted onto the edges of the battery cells 100.

[0003] Membrane strips 200 are typically made by cutting membrane sheets. The membrane sheets are carried on a carrier table, and after the membrane sheets are cut at the membrane cutting station, M membrane strips are obtained on the carrier table. Then, the carrier table moves the membrane strips to the membrane taking station.

[0004] Each time a membrane strip is picked up, the membrane strip transport mechanism can pick up N (e.g., 3) membrane strips from the platform for bonding to N solar cells, where N is less than M. If there is a defective cell among the N solar cells to be bonded with the membrane strip, the defective cell will be rejected, and the membrane strip corresponding to the defective cell will not be picked up and will remain on the platform. The membrane strips that are not picked up and remain on the platform are called NG membrane strips, and the membrane strips that are picked up by the membrane strip transport mechanism are called qualified membrane strips.

[0005] Since the carrier platform needs to return to the film cutting station after all the film strips have been retrieved, the NG film strips on the platform need to be removed to avoid affecting the next use of the platform. Currently, the method used is to use a film strip transport mechanism to pick up the remaining NG film strips and place them in the waste bin after each set of qualified film strips is placed, before picking up the next set of qualified film strips. However, this method causes the NG film strips to be thrown away, which reduces the working cycle of the film strip transport mechanism in picking up qualified film strips, thus affecting the transport efficiency of qualified film strips. Utility Model Content

[0006] To address the aforementioned technical problems, this application provides a membrane strip processing device, the detailed technical solution of which is as follows:

[0007] A membrane strip processing device includes a platform, a membrane strip transport mechanism, and a membrane strip recycling mechanism, wherein:

[0008] The platform is used to carry M membrane strips arranged side by side along a first direction. The platform is configured to move along the first direction to move the M membrane strips carried in batches to the membrane taking station in sequence. The number of membrane strips in each batch is N, and N < M.

[0009] The membrane strip transport mechanism is movably installed above the membrane picking station. The membrane strip transport mechanism includes N adsorption elements that can adsorb membrane strips. Each adsorption element is used to adsorb one membrane strip. The N adsorption elements are configured to pick up P qualified membrane strips located at the membrane picking station and transport the picked-up qualified membrane strips to the subsequent station, where P≤N.

[0010] The membrane strip recovery mechanism includes a first moving part and an absorption hood. The absorption hood is connected to the drive end of the first moving part. The first moving part is configured to drive the absorption hood to the membrane taking station after the adsorption element picks up P qualified membrane strips, and suck Q NG membrane strips left at the membrane taking station in the same batch into the absorption hood, where Q = NP.

[0011] The membrane strip processing device of this application, by setting up a membrane strip recycling mechanism, allows the membrane strip handling mechanism to collect qualified membrane strips from the current batch after the membrane strip transport mechanism picks them up. The membrane strip recycling mechanism then immediately collects the NG membrane strips remaining in the current batch. Before the membrane strip transport mechanism returns to pick up the next batch of membrane strips, the NG membrane strips left on the platform have already been collected by the membrane strip recycling mechanism. The membrane strip transport mechanism only needs to perform the transport action of qualified membrane strips, greatly improving the transport efficiency of qualified membrane strips. The membrane strip recycling mechanism collects NG membrane strips within each membrane picking cycle, so that when all qualified membrane strips on the platform are picked up, all NG membrane strips can also be collected, allowing the platform to quickly enter the next processing step, improving membrane strip processing efficiency. Simultaneously, the membrane strip recycling mechanism uses an absorption hood to directly suck up the NG membrane strips, eliminating the need for transporting NG membrane strips and further increasing efficiency.

[0012] In some embodiments, the membrane strip recycling mechanism further includes a collection cylinder and an air extraction device, wherein: the collection cylinder is provided with a feed inlet and an air extraction port, the feed inlet is connected to the absorption hood, the air extraction port is connected to the air extraction device, and the air extraction device is used to extract air from the collection cylinder through the air extraction port so that the adsorption port of the absorption hood generates an adsorption force, and Q NG membrane strips are sucked into the collection cylinder through the adsorption port of the absorption hood.

[0013] By evacuating the collection cylinder with the air extraction device, the absorption hood can directly suck Q NG membrane strips into the collection cylinder, thereby improving the recycling efficiency of NG membrane strips.

[0014] In some embodiments, the membrane strip recycling mechanism further includes a first pipe and a second pipe, wherein: the absorption hood is connected to the feed inlet of the collection cylinder via the first pipe; the air extraction component is connected to the air extraction port of the collection cylinder via the second pipe; the air extraction component is an adsorption fan or a vacuum generator.

[0015] By setting up the first and second pipes, long-distance connection between the inlet and outlet of the absorption hood, the air extraction component, and the collection cylinder is achieved.

[0016] In some embodiments, the collecting cylinder includes a cylinder body and a first cylinder cover, the first cylinder cover being fitted onto the cylinder body, an inlet and an exhaust port being provided on the cylinder body or the first cylinder cover, and a mesh plate being installed at the exhaust port, the mesh plate having multiple mesh holes arranged thereon, the mesh holes being used to prevent NG membrane strips from leaving the collecting cylinder through the exhaust port; or, the exhaust port is composed of multiple exhaust holes, the exhaust holes being used to prevent NG membrane strips from leaving the collecting cylinder through the exhaust port; or, the collecting cylinder includes an outer cylinder, an inner cylinder, and a second cylinder cover, wherein the inner cylinder is located inside the outer cylinder, the second cylinder cover is fitted onto the outer cylinder, the inner cylinder is detachably installed on the second cylinder cover or the outer cylinder, the inlet is provided on the inner cylinder and communicates with the inner cavity of the inner cylinder, the inner cylinder wall is provided with a plurality of vent holes penetrating the inner cylinder wall, the exhaust port is provided on the outer cylinder, an exhaust chamber communicating with the exhaust port is formed between the inner cylinder and the outer cylinder, the vent holes being used to prevent NG membrane strips from leaving the inner cylinder through the vent holes.

[0017] By configuring the collection cylinder to include a cylinder body and a first cylinder cover, the NG membrane strips can be easily removed by opening the first cylinder cover once the cylinder body is full. By installing a mesh plate at the air extraction port, or by configuring the air extraction port to consist of multiple air extraction holes, it is possible to prevent the NG membrane strips in the collection cylinder from being drawn out of the collection cylinder through the air extraction port.

[0018] By configuring the collection cylinder to include an outer cylinder, an inner cylinder, and a second cylinder cover, the NG membrane strips can be easily removed by opening the second cylinder cover once the inner cylinder is full. Furthermore, since the NG membrane strips are collected inside the inner cylinder, and an air extraction chamber communicating with the air extraction port is formed between the inner and outer cylinders, the NG membrane strips inside the inner cylinder are prevented from being drawn out of the collection cylinder through the air extraction port.

[0019] In some embodiments, the absorption hood has a flat structure and is horizontally arranged, and the adsorption port is located at one end of the absorption hood facing the film taking station. The adsorption port extends along a second direction, which is perpendicular to the first direction.

[0020] By setting the absorber cover to a flat and horizontal structure, the vertical dimension of the absorber cover can be shortened, allowing the absorber cover to smoothly extend between the membrane strip transport mechanism and the platform to recycle the NG membrane strip, avoiding contact and interference with the membrane strip transport mechanism.

[0021] In some embodiments, the membrane strip transport mechanism further includes a second moving part and a first mounting frame, wherein: the adsorption member is a strip-shaped adsorption member with an adsorption hole at the bottom, and each adsorption member can independently adsorb the corresponding membrane strip through the corresponding adsorption hole, and the adsorption hole is also used for backflushing the membrane strip; the first mounting frame is connected to the movable part of the second moving part, and N adsorption members are arranged side by side on the first mounting frame along a first direction, and the second moving part is configured to drive the N adsorption members to move synchronously.

[0022] Since each adsorption element's adsorption hole independently performs air intake and air blowing, when N adsorption elements move above the film-taking station under the drive of the second moving part, the adsorption holes of the adsorption elements corresponding to qualified film strips are controlled to intake air, thereby adsorbing the qualified film strips. At the same time, the adsorption holes of the adsorption elements corresponding to NG film strips are controlled to blow air, thereby preventing NG film strips from being carried away from the film-taking station by qualified film strips.

[0023] In some embodiments, the membrane strip transport mechanism further includes a spacing drive unit disposed on the first mounting frame. The spacing drive unit is connected to the N adsorption elements in a transmission manner. The spacing drive unit is used to drive the N adsorption elements to slide closer to the center or slide apart to both sides to adjust the spacing between the N adsorption elements.

[0024] By incorporating a spacing drive unit, the spacing between the N adsorption elements can be flexibly adjusted. Before picking up a qualified membrane strip, the spacing drive unit drives the N adsorption elements to slide towards the center, facilitating the picking up of the qualified membrane strip. Before placing the picked-up qualified membrane strip to the next processing station, the spacing drive unit drives the N adsorption elements to slide apart to both sides, thereby achieving the spacing processing of the picked-up qualified membrane strip to meet the requirements of the next process.

[0025] In some embodiments, the membrane strip processing apparatus further includes a pressing mechanism, which includes pressing claws movably disposed above the platform and opposite to the absorption hood; when the adsorption element picks up a qualified membrane strip at the membrane strip taking station, or when the absorption hood absorbs an NG membrane strip at the membrane strip taking station, the pressing claws are configured to press the membrane strips adjacent to the membrane strip taking station in the next batch onto the platform.

[0026] By setting up pressure claws, it is prevented that during the process of the adsorption component picking up qualified membrane strips at the membrane picking station, or during the process of the absorption hood absorbing NG membrane strips at the membrane picking station, the membrane strips adjacent to the membrane picking station in the next batch are not carried away from the carrier.

[0027] In some embodiments, the film pressing mechanism further includes a third moving part and a second mounting frame, wherein: the second mounting frame is connected to the drive end of the third moving part; the pressing claw is connected to the end of the second mounting frame, and the pressing end of the pressing claw is provided with pressing teeth arranged at intervals along a second direction, each pressing tooth being used to cooperate in pressing a film strip, the second direction being perpendicular to the first direction; the third moving part is configured to drive the second mounting frame to move, so as to drive the pressing claw to press the film strip adjacent to the film taking station in the next batch onto the carrier.

[0028] The pressure claws press the membrane strip onto the carrier by spaced pressure teeth along the second direction (i.e., the length direction of the membrane strip) at their pressing ends, which can ensure the pressing force on the membrane strip and at the same time prevent the membrane strip from sticking together.

[0029] In some embodiments, the film pressing mechanism further includes an air blowing block disposed on a second mounting frame; the air blowing block is provided with air blowing ports at intervals along a second direction, the air blowing ports being offset from the pressing teeth, and the air blowing block is used to blow air toward the film taking station when the absorption hood absorbs the NG film strip at the film taking station, so as to blow the NG film strip toward the absorption hood.

[0030] The air blowing block lifts the NG membrane strip from the carrier and blows it toward the absorption hood, which helps the NG membrane strip move toward the absorption hood and further ensures that the absorption hood can smoothly suck in the NG membrane strip on the carrier.

[0051] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] As described in the background section, the current method for retrieving NG membrane strips involves using a membrane strip transport mechanism to pick up any NG membrane strips that have not been removed after each set of qualified membrane strips has been placed and put into a waste bin before picking up the next set of qualified membrane strips. However, this method results in the NG membrane strips being thrown away, which takes up the working cycle of the membrane strip transport mechanism in picking up qualified membrane strips, thus affecting the transport efficiency of qualified membrane strips.

[0053] To address the aforementioned technical problems, this application provides a membrane strip processing device that eliminates the need to interrupt the working cycle of the membrane strip transport mechanism in picking up qualified membrane strips, thereby improving the transport efficiency of qualified membrane strips.

[0054] like Figures 1 to 5 As shown, the membrane strip processing device of this application includes a platform 1, a membrane strip conveying mechanism 2, and a membrane strip recycling mechanism 3, wherein:

[0055] The platform 1 is used to carry M membrane strips arranged side by side along a first direction (such as the X direction). The platform 1 is configured to move along the first direction to move the M membrane strips carried in batches to the membrane taking station C in sequence. The number of membrane strips in each batch is N, and N < M.

[0056] The membrane strip transport mechanism 2 is movably disposed above the membrane picking station. The membrane strip transport mechanism 2 includes N adsorption elements 21 that can adsorb membrane strips. Each adsorption element 21 is used to adsorb one membrane strip. The N adsorption elements 21 are configured to pick up P qualified membrane strips located at the membrane picking station and transport the picked-up qualified membrane strips to the subsequent station, where P≤N.

[0057] The membrane strip recycling mechanism 3 includes a first moving part 31 and an absorption cover 32. The absorption cover 32 is connected to the drive end of the first moving part 31. The first moving part 31 is configured to drive the absorption cover 32 to the membrane taking station after the adsorption member 21 picks up P qualified membrane strips, and suck Q NG membrane strips left at the membrane taking station in the same batch into the absorption cover 32, where Q = NP.

[0058] The membrane strip processing device of this application incorporates a membrane strip recycling mechanism 3. After the membrane strip transport mechanism 2 picks up the qualified membrane strips from the current batch, the membrane strip recycling mechanism 3 immediately follows and collects the NG membrane strips remaining in the current batch. Before the membrane strip transport mechanism 2 returns to pick up the next batch of membrane strips, the NG membrane strips left on the carrier 1 have already been collected by the membrane strip recycling mechanism 3. The membrane strip transport mechanism 2 only needs to perform the transport action of qualified membrane strips, greatly improving the transport efficiency of qualified membrane strips. The membrane strip recycling mechanism 3 collects NG membrane strips within each membrane picking cycle, so that when all qualified membrane strips on the carrier 1 are picked up, all NG membrane strips can also be collected, and the carrier 1 can quickly enter the next processing step, improving the membrane strip processing efficiency.

[0059] Meanwhile, the membrane strip recycling mechanism 3 uses the absorption hood 32 to directly suck away the NG membrane strips, eliminating the need for handling the NG membrane strips and making it more efficient.

[0060] To enable those skilled in the art to more clearly understand the technical solution of this application, the working process of the membrane strip processing device of this application will be described exemplarily below through an embodiment.

[0061] like Figure 3 As shown, the film strip transport mechanism 2 in this embodiment includes three (i.e., N=3) adsorption elements 21. The platform 1 translates along the first direction between the film cutting station and the film taking station C.

[0062] First, the empty carrier platform 1 is moved to the film cutting station, and the film strip to be cut is placed on the carrier platform 1. The film strip cutting mechanism descends and cuts the film strip into 9 strips (M=9). The 9 strips are arranged side by side along the first direction, with each batch consisting of 3 strips. The first batch of 3 strips is closest to the film picking station C, the third batch of 3 strips is furthest from the film picking station C, and the second batch of 3 strips is located between the first batch of 3 strips and the third batch of 3 strips.

[0063] The control platform 1 is moved towards the film picking station C, so that the first batch of 3 film strips are moved to the film picking station C. Then, the control film strip transport mechanism 2 is moved above the film picking station C, and according to the number P of qualified film strips in the first batch (for example, if the number of qualified film strips in the first batch is 2, i.e., P=2), the control P adsorption elements 21 in the film strip transport mechanism 2 pick up one qualified film strip from the film picking station C and transport the picked-up qualified film strip to the next station.

[0064] After P qualified membrane strips are picked up from the membrane taking station C by the adsorption unit 21, the first moving part 31 immediately drives the absorption hood 32 to move to the membrane taking station C, and sucks Q (e.g., 1 strip, i.e., Q=1) NG membrane strips left at the membrane taking station C in the first batch into the absorption hood 32. Of course, if all membrane strips in the first batch are qualified membrane strips, the membrane strip recycling mechanism 3 does not need to perform a recycling operation.

[0065] The control platform 1 continues to move towards the film picking station C, so that the three film strips of the second batch are moved to the film picking station C. Subsequently, the control film strip transport mechanism 2 and the film strip recycling mechanism 3 complete the picking and recycling of qualified and NG film strips in the second batch of film strips. The specific process is the same as the processing process of the first batch of film strips.

[0066] The control platform 1 continues to move towards the film picking station C, moving the three film strips of the third batch to station C. Subsequently, the control film strip transport mechanism 2 and film strip recycling mechanism 3 respectively pick up and retrieve the qualified and NG film strips from the third batch, following the same process as for the first batch. At this point, all film strips on the control platform 1 have been removed.

[0067] Once again, control the stage 1 to move to the film cutting station and begin the next round of film strip processing.

[0068] like Figure 4 As shown, in some embodiments, the stage 1 is connected to the movable part of the translation drive unit 5, and the translation drive unit 5 drives the stage 1 to translate along a first horizontal direction.

[0069] The translation drive unit 5 can adopt various existing linear drive mechanisms that can drive the stage 1 to translate along the first horizontal direction, such as ball screw linear drive modules, synchronous belt linear drive modules, etc.

[0070] like Figures 5 to 8 As shown, in some embodiments, the membrane strip recycling mechanism 3 of this application further includes a collection cylinder 33 and an air extraction component 34, wherein: the collection cylinder 33 is provided with a feed inlet 331 and an air extraction port 332, the feed inlet 331 is connected to the absorption cover 32, the air extraction port 332 is connected to the air extraction component 34, and the air extraction component 34 is used to extract air from the collection cylinder 33 through the air extraction port 332 so that the adsorption port 321 of the absorption cover 32 generates an adsorption force, and Q NG membrane strips are sucked into the collection cylinder 33 through the adsorption port 321 of the absorption cover 32.

[0071] By evacuating the collection cylinder 33 through the evacuation device 34, the absorption hood 32 can directly suck Q NG membrane strips into the collection cylinder 33, thereby improving the recycling efficiency of NG membrane strips.

[0072] In some embodiments, the membrane strip recycling mechanism 3 further includes a first pipe 35 and a second pipe 36, wherein: the absorption hood 32 is connected to the feed inlet 331 of the collection cylinder 33 via the first pipe 35; and the air extraction component 34 is connected to the air extraction port 332 of the collection cylinder 33 via the second pipe 36.

[0073] By setting up the first pipe 35 and the second pipe 36, the inlet 331 and the outlet 332 of the absorption hood 32, the air extraction component 34 and the collection cylinder 33 are connected at a long distance, which facilitates the installation of the absorption hood 32, the air extraction component 34 and the collection cylinder 3.

[0074] The extraction component 34 is an adsorption fan or a vacuum generator.

[0075] Figures 7 to 8 In the illustrated embodiment, the collecting cylinder 33 includes a cylinder body 334 and a first cylinder cover 335. The first cylinder cover 335 is fitted onto the cylinder body 334, and the feed inlet 331 and the air extraction port 332 are located on the first cylinder cover 335. Of course, the feed inlet 331 and the air extraction port 332 can also be located on the cylinder body 334. When the cylinder body 334 is full of NG film strips, the first cylinder cover 335 can be opened to easily remove the NG film strips.

[0076] like Figure 8 As shown, the air extraction port 332 is configured to consist of multiple air extraction holes 333, which are used to prevent the NG membrane strip from leaving the collection cylinder 33 through the air extraction port 332. Alternatively, a mesh plate with multiple mesh holes can be installed at the air extraction port 332 to prevent the NG membrane strip from leaving the collection cylinder 33 through the air extraction port 332.

[0077] like Figures 9 to 10As shown, in another embodiment, the collecting cylinder 33 includes an outer cylinder 337, an inner cylinder 336, and a second cylinder cover 338. The inner cylinder 336 is located inside the outer cylinder 337, and the second cylinder cover 338 covers the outer cylinder 337. The inner cylinder 336 is detachably mounted on the second cylinder cover 338. Alternatively, the inner cylinder 336 can also be detachably mounted on the outer cylinder 337. The feed inlet 331 is located on the inner cylinder 336 and communicates with the inner cavity of the inner cylinder 336. The inner cylinder 336 has several vent holes 339 penetrating the inner cylinder 336. The air extraction port 332 is located on the outer cylinder 337. An air extraction chamber 3310 communicating with the air extraction port 332 is formed between the inner cylinder 336 and the outer cylinder 337. The vent holes 339 are used to prevent the NG film strip from leaving the inner cylinder 336 through the vent holes 339.

[0078] Once the inner cylinder 336 is full of NG membrane strips, the second cylinder cover 338 can be opened to easily remove the NG membrane strips. Furthermore, since the NG membrane strips are collected inside the inner cylinder 336, and an air extraction chamber 3310 communicating with the air extraction port 332 is formed between the inner cylinder 336 and the outer cylinder 337, it is possible to prevent the NG membrane strips inside the inner cylinder 336 from being drawn out of the collection cylinder 33 via the air extraction port 332.

[0079] like Figures 4 to 5 As shown, in some embodiments, the absorption cover 32 is a flat structure and is horizontally arranged. The adsorption port 321 is located at one end of the absorption cover 32 facing the film taking station C. The adsorption port 321 extends along a second direction (e.g., the Y direction), which is perpendicular to the first direction.

[0080] By setting the absorption hood 32 to a flat and horizontal structure, its vertical dimensions can be reduced. This allows the absorption hood 32 to smoothly extend between the membrane strip transport mechanism 2 and the platform 1 to recover NG membrane strips, avoiding contact or interference with the membrane strip transport mechanism 2. In other words, after the adsorption element 21 of the membrane strip transport mechanism 2 picks up a qualified membrane strip from the membrane picking station C, the absorption hood 32 can extend between the membrane strip transport mechanism 2 and the platform 1 to recover the NG membrane strip without waiting for the adsorption element 21 of the membrane strip transport mechanism 2 to leave above the membrane picking station C, thereby further improving processing efficiency.

[0081] like Figure 3 As shown, in some embodiments, the membrane strip transport mechanism 2 further includes a second moving part and a first mounting frame 22, wherein: the adsorption member 21 is a strip-shaped adsorption member 21 with adsorption holes at the bottom, and each adsorption member 21 can independently adsorb the corresponding membrane strip through the corresponding adsorption holes, which are also used for backflushing the membrane strip. The first mounting frame 22 is connected to the movable part of the second moving part, and N adsorption members 21 are arranged side by side on the first mounting frame 22 along a first direction. The second moving part is configured to drive the N adsorption members 21 to move synchronously.

[0082] Since each adsorption element 21 independently performs air intake and air blowing, when N adsorption elements 21 move to above the film taking station C under the drive of the second moving part, the adsorption holes of the adsorption element 21 corresponding to the qualified film strip are controlled to intake air, thereby adsorbing the qualified film strip. At the same time, the adsorption holes of the adsorption element 21 corresponding to the NG film strip are controlled to blow air, thereby preventing the NG film strip from being carried away from the film taking station C by the qualified film strip.

[0083] The second moving part can adopt various existing moving mechanisms capable of driving the first mounting frame 22 to move, such as a moving mechanism composed of a translation drive module and a lifting drive module, wherein the translation drive module is used to drive the first mounting frame 22 to translate, and the lifting drive module is used to drive the first mounting frame 22 to lift. The second moving part can also adopt other mechanisms such as a robotic arm.

[0084] The slit membrane strips formed on the stage 1 are adjacent to each other, but the subsequent processing steps require the membrane strips to have a larger spacing.

[0085] like Figure 3 As shown, in some embodiments, the film strip transport mechanism 2 further includes a spacing drive 23 disposed on the first mounting frame 22. The spacing drive 23 is connected to the N adsorption members 21 in a transmission manner. The spacing drive 23 is used to drive the N adsorption members 21 to slide closer to the middle or slide apart to both sides to adjust the spacing between the N adsorption members 21.

[0086] By incorporating the spacing drive unit 23, the spacing between the N adsorption elements 21 can be flexibly adjusted. Before picking up a qualified film strip, the spacing drive unit 23 drives the N adsorption elements 21 to slide closer together towards the center, facilitating the picking up of the qualified film strip. Before placing the picked-up qualified film strip to the next processing station, the spacing drive unit 23 drives the N adsorption elements 21 to slide apart to both sides, thereby achieving the spacing processing of the picked-up qualified film strip.

[0087] like Figures 1 to 2 and Figure 4 As shown, in some embodiments, the film strip processing apparatus of this application further includes a film pressing mechanism 4, which includes a pressing claw 41. The pressing claw 41 is movably disposed above the platform 1 and opposite to the absorption cover 32. When the adsorption member 21 picks up a qualified film strip at the film taking station C, or when the absorption cover 32 absorbs an NG film strip at the film taking station C, the pressing claw 41 is configured to press the film strip adjacent to the film taking station C in the next batch onto the platform 1.

[0088] In this way, it can be avoided that during the process of the adsorption element 21 picking up the qualified membrane strip at the membrane picking station C, or during the process of the absorption cover 32 absorbing the NG membrane strip at the membrane picking station C, the membrane strip adjacent to the membrane picking station in the next batch is not carried away from the carrier table 1.

[0089] like Figure 4 and Figures 11 to 12 As shown, in some embodiments, the film pressing mechanism 4 further includes a third moving part 42 and a second mounting frame 43, wherein the second mounting frame 43 is connected to the drive end of the third moving part 42. A pressing claw 41 is connected to the end of the second mounting frame 43, and the pressing end of the pressing claw 41 is provided with pressing teeth 411 spaced apart along a second direction (e.g., the Y-axis direction). Each pressing tooth 411 is used to cooperate in pressing a film strip, and the second direction is perpendicular to the first direction. The third moving part 42 is configured to drive the second mounting frame 43 to move, thereby causing the pressing claw 41 to press the film strip adjacent to the film taking station C in the next batch onto the platform 1.

[0090] The pressure claw 41 presses the membrane strip onto the carrier 1 with pressure teeth 411 arranged at intervals along the second direction (i.e. the length direction of the membrane strip) at its pressing end, which can ensure the pressing force of the membrane strip and at the same time avoid the membrane strip from sticking.

[0091] The third moving part 42 can adopt various existing moving mechanisms capable of driving the second mounting bracket 43 to move, such as a moving mechanism composed of a translation drive module and a lifting drive module, wherein the translation drive module is used to drive the second mounting bracket 43 to translate, and the lifting drive module is used to drive the second mounting bracket 43 to lift. The third moving part 42 can also adopt other mechanisms such as a robotic arm.

[0092] For example, 11 to Figure 12 As shown, in some embodiments, the film pressing mechanism 4 further includes an air blowing block 44 disposed on the second mounting bracket 43. The air blowing block 44 is provided with air blowing ports 441 spaced apart along the second direction. The air blowing ports 441 are offset from the pressing teeth 411. The air blowing block 44 is used to blow air toward the film taking station C when the absorption cover 32 absorbs the NG film strip at the film taking station C, so as to blow the NG film strip toward the absorption cover 32.

[0093] The air blowing block 44 blows the NG film strip off the stage 1 and towards the adsorption port 321 of the absorption hood 32, which helps the NG film strip move toward the adsorption port 321 and further ensures that the adsorption port 321 of the absorption hood 32 can smoothly suck in the NG film strip on the stage 1.
