Description

Technical Field

[0001] This application relates to the field of automated production equipment technology, and in particular to a multi-workpiece batch operation equipment. Background Technology

[0002] In the production process of consumer electronics products, in order to meet the mass production needs of workpieces (such as glass covers, gemstone covers, etc.), after completing surface strengthening or cleaning operations, multiple workpieces need to be simultaneously placed on a large film (a large-size base film with a large overall area to support multiple workpieces at the same time). Then, the large film and the multiple workpieces on it are placed on a processing board for overall processing (such as coating, sandblasting, etc.), thereby realizing the batch storage and transfer of workpieces. After that, the workpieces on each large film need to be separated for subsequent production operations. Current single-line / multi-line continuous operation equipment (such as the commonly available multi-channel film peeling and laminating equipment) cannot meet this type of production demand.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0062] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0063] To address the technical problem that existing equipment cannot meet the needs of multi-workpiece batch operation, this application provides a multi-workpiece batch operation equipment that can achieve continuous multi-workpiece batch operation through the cooperation of a fixture loading and unloading mechanism 300, a film tearing mechanism 100, a transfer mechanism 400, and a workpiece separation mechanism 200, which is beneficial to improving the efficiency of automated operation.

[0064] In the embodiments of this application, a multi-workpiece batch processing device is used to perform continuous multi-workpiece batch processing on the coated workpiece 824. For details, please refer to... Figure 7 To achieve the overall processing of multiple workpieces 824, they need to be mounted on the same large film body 822. When the large film body 822 itself is not adhesive, adhesive small films 823 are used to bond the multiple workpieces 824 to the large film body 822, thus connecting the multiple workpieces 824, the multiple small films 823, and the large film body 822 into a whole, namely the large film 820. To facilitate the overall processing of the multiple workpieces 824 on the large film 820, the back of the large film 820 needs to be adhered to a fixture 810, such as a coating plate, using double-sided adhesive 821. The fixture 810 provides support for the multiple workpieces 824. After the overall coating is completed, the fixture 810 and the large film 820 need to be separated first by a film-peeling mechanism 100, and then the workpieces 824 need to be separated from the large film 820 by a workpiece separation mechanism 200, thereby achieving continuous multi-workpiece batch processing.

[0065] Please see Figures 1 to 27 This application provides a multi-workpiece batch processing device, including a film-peeling mechanism 100, a workpiece separation mechanism 200, a fixture loading / unloading mechanism 300, and a transfer mechanism 400. The film-peeling mechanism 100 includes a film-peeling station where, after the coating fixture 800 completes overall coating, a large film 820 carrying a large number of workpieces 824 can be peeled off from the fixture 810 at the film-peeling station. The workpiece separation mechanism 200 includes a part-removal station where multiple workpieces 824 carried on the large film 820 can be removed to facilitate subsequent workpiece 824 production operations, such as... Figure 1 , Figure 2 and Figure 13 As shown.

[0066] Please see Figure 1 The fixture loading and unloading mechanism 300 includes a movable conveying end 310. The conveying end 310 moves through the film-tearing station, and can transport the film-coating fixture 800 to the film-tearing station of the film-tearing mechanism 100 via the conveying end 310, facilitating the separation operation between the large film 820 and the fixture 810. After the separation operation between the large film 820 and the fixture 810 is completed, the fixture 810 can be removed from the film-tearing station via the conveying end 310 and transported to the unloading area, facilitating the next film-tearing operation at the film-tearing station.

[0067] The transfer mechanism 400 includes a movable film-lifting end 410, which moves between the film-tearing station and the part-picking station, such as... Figure 1 , Figure 8 and Figure 12 As shown. The film lifting end 410 can transfer the large film 820 separated from the film tearing station to the part picking station, which facilitates the separation operation of the workpiece 824 from the large film 820 at the part picking station.

[0068] It should be noted that in this application, the film-coating fixture 800 is first transported to the film-tearing station by the fixture loading and unloading mechanism 300. Then, the film-tearing mechanism 100 separates the fixture 810 from the large film 820. Next, the film-lifting end 410 in the transfer mechanism 400 moves the large film 820, which is covered with a large number of workpieces 824, from the film-tearing station of the film-tearing mechanism 100 to the part-picking station of the workpiece separation mechanism 200. Finally, the workpiece separation mechanism 200 separates the product from the large film 820. The entire film-tearing process requires no manual intervention, enabling automated film-tearing and continuous multi-workpiece batch operation, which is beneficial to improving the efficiency of automated operation.

[0069] In existing large film peeling methods, the large film 820 is typically peeled open from the end of the fixture 810 (such as the coating plate), creating a tearing opening between the large film 820 and the coating plate (i.e., the fixture 810), with a separation angle on the inner side of the tearing opening. To allow the large film 820 to separate from the coating plate, it is stretched to the largest possible separation angle. Since the large film 820 is a flexible film, it can deform with the angle. However, when the workpiece 824 is at a large separation angle, because the workpiece 824 is a rigid structure, it cannot deform with the separation angle and is prone to breakage at the separation angle, leading to a decrease in workpiece 824 yield and production volume. Furthermore, the different degrees of deformation between the workpiece 824 and the large film 820 can disrupt the adhesion between them during peeling.

[0070] To address the aforementioned issues, please refer to some embodiments of this application. Figure 2 and Figure 3 The film-tearing mechanism 100 includes an auxiliary film-tearing component 110 slidably disposed at the film-tearing station. The sliding direction of the auxiliary film-tearing component 110 is parallel to the film-tearing direction, and it is used to assist in the separation of the fixture 810 and the large film 820 in the film-coating fixture 800 at the film-tearing station.

[0071] Specifically, the auxiliary film-tearing assembly 110 is slidably mounted on the worktable body 620, and the film-lifting end 410 is positioned opposite to the worktable body 620 to clamp the end of the large film 820. The film-lifting end 410 can move relative to the film-tearing station, thereby moving the large film 820 away from the fixture 810, creating a film-tearing opening between the large film 820 and the fixture 810 and achieving separation. Figure 2 and Figure 8 As shown. The auxiliary film-tearing assembly 110 includes a separating member 111. During the film-tearing stroke of the auxiliary film-tearing assembly 110, the separating member 111 moves above the film-tearing station along the film-tearing direction, so that the separating member 111 extends into the film-tearing opening formed between the large film 820 and the fixture 810, so that the separating member 111 acts on the back side of the large film 820, thereby separating the back side of the large film 820 from the fixture 810.

[0072] In this application, by sliding the auxiliary film-tearing assembly 110 onto the worktable body 620, the separator 111 moves above the film-tearing station along the film-tearing direction. During the film-tearing process, the separator 111 continuously applies force to the back of the large film 820, thus assisting in film-tearing. By moving and pushing the back of the large film 820, the separator 111 can separate the large film 820 from the fixture 810 at a smaller separation angle. This avoids the workpiece 824, which is bonded to the front of the large film 820, from breaking at the separation angle when the separation angle between the large film 820 and the fixture 810 is large. It also avoids damaging the adhesion between the large film 820 and the workpiece 824 during film-tearing, which helps improve the yield of the workpiece 824 and ensures the production volume of the workpiece 824.

[0073] To improve the film-tearing efficiency, the large film 820 is torn open simultaneously at both ends of the fixture 810, so that both sides of the fixture 810 have film-tearing openings. See some embodiments of this application for details. Figure 2 and Figure 3 Two sets of auxiliary film-tearing components 110 are provided and distributed on both sides of the film-tearing station. The two sets of auxiliary film-tearing components 110 slide in opposite directions and can act on both sides of the large film 820 simultaneously, tearing the large film 820 from the edge to the center. By using two sets of auxiliary film-tearing components 110 for film tearing, the film-tearing efficiency can be greatly improved.

[0074] Furthermore, the tearing stroke lengths of the two sets of auxiliary film-tearing components 110 are different. This is because multiple strips of double-sided adhesive 821 are adhered to the back of the large film body 822, which allows the large film 820 and the workpiece 824 carried on the large film 820 to be firmly attached to the fixture 810, facilitating coating operations when used with the coating machine along with the fixture 810. When the fixture 810 is long (e.g., over 1 meter), in order to ensure a tight fit between the back of the large film 820 and the fixture 810, in addition to setting double-sided adhesive 821 around the large film 820, at least one strip of double-sided adhesive 821 needs to be set in the middle of the large film 820. Figure 4 As shown. When the jig 810 is provided with double-sided tape 821 in the middle, the tearing stroke of one of the auxiliary film-tearing components 110 needs to exceed 1 / 2 of the length of the jig 810 in order to completely separate the large film 820 in the middle of the film-coating jig 800 from the jig 810.

[0075] Specifically, during film removal, the lifting end 410 clamps and lifts the large films 820 at both ends of the fixture 810, creating a film removal opening between the large films 820 and the fixture 810. The separating member 111 of the auxiliary film removal assembly 110 extends into the film removal opening. The two sets of auxiliary film removal assemblies 110 move towards each other, gradually widening the film removal opening on both sides of the large films 820 to achieve film removal. When the two sets of auxiliary film removal assemblies 110 approach the middle of the fixture 810, one set of auxiliary film removal assemblies 110 slides back to its original position, while the other set of auxiliary film removal assemblies 110 continues to move in its film removal direction until the large films 820 in the middle of the covering fixture 800 are completely separated from the fixture 810. During the film removal process, the different film removal stroke lengths of the two sets of auxiliary film removal assemblies 110 also prevent interference between the two sets of auxiliary film removal assemblies 110 in the middle of the fixture 810.

[0076] Preferably, the tearing stroke of one set of auxiliary film-tearing components 110 covers at least 3 / 5 of the length of the fixture 810.

[0077] In the above embodiments, the separating member 111 can directly push the back of the large film 820, and can at least apply a horizontal force to the back of the large film 820 to assist in tearing the film. However, if the separating member 111 can not only apply a horizontal force, but also push the large film 820 in a vertically upward direction, it will be more conducive to separating the large film 820 from the bottom fixture 810.

[0078] To achieve the above effects, the separating member 111 can be a sheet or plate structure tilted upwards, or it can be a component that can apply force to the back of the large membrane 820 by rotation. To prevent the separating member 111 from adhering to the double-sided adhesive 821 on the back of the large membrane 820, the outer peripheral surface of the separating member 111 has an anti-adhesive layer 1111, such as... Figure 5 As shown.

[0079] In some embodiments of this application, please refer to Figure 3 and Figure 5 The separator 111 is rotatably configured, and when the sliding tearing direction of the separator 111 is... Figure 5 When moving from left to right, the separating member 111 rotates counterclockwise, which can apply an upward force to the back of the large membrane 820, which is beneficial for separating the large membrane 820 and the bottom fixture 810.

[0080] In some embodiments of this application, the cross-section of the separator 111 is an eccentric structure, such as... Figure 5 As shown. When the separator 111 rotates counterclockwise around its own rotation axis 1112, the protruding part on the right side of the eccentric structure has a longer lever arm, which can exert a larger inclined upward force on the back of the large membrane 820 through the protruding part on the right side of the eccentric structure.

[0081] It should be noted that, in addition to being an eccentric structure, it can also be Figure 5 The cam structure shown can also be an ellipse, a polygon with rounded corners, or other similar structures.

[0082] In some embodiments of this application, the auxiliary film-tearing assembly 110 further includes a first driving member 112, a mounting slide 113, a first slide rail 114, and a second driving member 115. The separating member 111 is rotatably mounted on the mounting slide 113. The first driving member 112 is connected to the rotation shaft 1112 of the separating member 111 and is used to drive the separating member 111 to rotate. The mounting slide 113 is slidably connected to the first slide rail 114 and is driven by the second driving member 115 to reciprocate along the length direction of the first slide rail 114.

[0083] It should be noted that during the coating process on the workpiece 824 on fixture 810, the coating solution may adhere to the surface of fixture 810. Prolonged accumulation of the coating solution and dust can affect the quality of workpiece 824. Since a large film 820 is attached to the upper surface of fixture 810, it not only supports workpiece 824 but also protects the upper surface of fixture 810. Side films are typically added to both sides of fixture 810 for further protection, preventing coating solution from accumulating on the sides and affecting the quality of workpiece 824. To ensure the coating quality of workpiece 824 in the next process, when removing the large film 820 carrying the coated workpiece 824 from fixture 810, the side films with coating solution adhering to them on both sides of fixture 810 must also be removed before fixture 810 can proceed to the next coating process.

[0084] To address the aforementioned issues, please refer to some embodiments of this application. Figure 1 , Figure 2 and Figure 10 The film-tearing station includes a first film-tearing position and a second film-tearing position. The first film-tearing position is located near the workpiece separation mechanism 200, where the large film 820 can be separated from the fixture 810. An auxiliary film-tearing assembly 110 is correspondingly positioned at the first film-tearing position, such as... Figure 2 As shown. The second film-tearing position is located near the fixture loading and unloading mechanism 300. At the second film-tearing position, the side films on both sides of the fixture 810 can be torn off.

[0085] To facilitate the removal of the side films on both sides of the fixture, please refer to some embodiments of this application. Figure 10The second tearing position has a side film tearing assembly 130 provided on the side of the fixture 810 along its length direction, which facilitates tearing off the side films on both sides of the coating fixture 800. Specifically, the second tearing position has multiple side film tearing assemblies 130 on both sides of the fixture 810 along its length direction, which facilitates the removal of the side films on both sides of the fixture 810 along its length direction. The second tearing position has a flipping assembly 120 provided on the side of the fixture 810 along its width direction, which facilitates the flipping of the coating fixture 800 as a whole, which can improve the stability of the flipping of the fixture 810 and reduce the longitudinal space required for the flipping of the fixture 810.

[0086] It should be noted that the first and second film-tearing positions can be set on different worktables 600 or on the same worktable 600. In this application, in order to reduce the transfer distance of the coating fixture 800, the first and second film-tearing positions are set side by side on the same worktable 600, such as... Figure 1 As shown.

[0087] Because the end dimensions of the large film 820 and the length dimensions of the side film are both large, multiple clamping points need to be formed at the end of the large film 820 and along the length of the side film to ensure a good tearing effect. Therefore, in some embodiments of this application, please refer to... Figure 9 and Figure 10 Both the lifting end 410 and the side film tearing assembly 130 include multiple clamping members. The lifting end 410 includes multiple first clamping members 411, and the arrangement of these first clamping members 411 matches the end structure of the fixture 810. When the upper surface of the coating plate (i.e., the fixture 810) is an arc surface matching the coating machine, the end of the large film 820 also has an arc-shaped structure, and the multiple first clamping members 411 are arranged in a fan shape to facilitate clamping the arc-shaped end of the large film 820. The side film tearing assembly 130 includes multiple second clamping members 131 arranged along the length direction of the fixture 810, which can form multiple clamping points along the length direction of the side film. In addition, the side film tearing assembly 130 also includes a horizontal drive member 132 and a first lifting drive member 133 corresponding to the second clamping member 131, which are used to realize the movement of the second clamping member 131 relative to the fixture 810, so as to facilitate the second clamping member 131 to clamp the side film and move in a direction away from the fixture 810 to complete the side film tearing.

[0088] Specifically, both the first clamping member 411 and the second clamping member 131 include grippers and cylinders or hydraulic cylinders for opening and closing the grippers. The grippers are coated with an anti-stick coating, which can be used to clamp and release the large film or side film. The second clamping member 131 is connected to the horizontal drive member 132, which moves the second clamping member 131 horizontally to move closer to or away from the fixture 810. The horizontal drive member 132 is connected to the first lifting drive member 133. Under the action of the first lifting drive member 133, the horizontal drive member 132 and the second clamping member 131 move vertically as a whole, which facilitates the removal of the side film from the fixture 810.

[0089] It should be noted that side film tearing assemblies 130 are provided on both sides of the second tearing position. When the fixture 810 is in a vertical position, the side film on one side of the fixture 810 is torn off. Then, the second clamping member 131 moves away from the fixture 810 under the action of the horizontal driving member 132, making room for the fixture 810 to rotate. The fixture 810 rotates 180 degrees under the action of the flipping assembly 120, and the side film on the other side of the fixture 810 is torn off by the side film tearing assembly 130 on the other side of the second tearing position.

[0090] In some embodiments of this application, please refer to Figure 6 , Figure 9 , Figure 10 and Figure 11 The clamping elements (i.e., the first clamping element 411 and the second clamping element 131) are matched with the clamping relief openings on the laminating fixture 800. Specifically, the fixture 810 has first clamping relief openings 811 at both ends, creating a notch between the end of the fixture 810 and the end of the large film 820, allowing the first clamping element 411 to extend into the notch to clamp the large film 820. The fixture 810 also has second clamping relief openings 812 on both sides, facilitating the second clamping element 131 to extend into the second clamping relief openings 812 to clamp the side film, thereby improving the ease of film tearing and operational efficiency.

[0091] In some embodiments of this application, please refer to Figure 3 and Figure 10 Both ends of the first and second film-tearing positions are slidably provided with fixture fixing components 150, which can be used to fix them to both ends of the fixture 810, facilitating the tearing of the large film 820 and the side film. Specifically, the fixture fixing component 150 includes a fixing end 151, a third driving member 152, and a fixing end slide 153. The fixing end 151 has a connecting part for connecting to the end of the fixture 810, which can be a connecting seat, a pin, or other components. The fixing end 151 is disposed on the fixing end slide 153, and the fixing end slides 153 at both ends can move relative to each other under the action of the third driving member 152, which facilitates matching with the length of the fixture 810, thereby fixing both ends of the fixture 810.

[0092] In some embodiments of this application, please refer to Figure 10 The fixture fixing components 150 at both ends of the second film-tearing position are connected to the flipping component 120, which facilitates the flipping component 120 to drive the fixture 810 to rotate. Specifically, the flipping component 120 is connected to the fixed end 151, which can drive the fixed end 151 to rotate relative to the fixed end slide 153, thereby realizing the rotation of the fixture 810 and facilitating the removal of the side films on both sides of the fixture 810.

[0093] In the above embodiments, after the side film is torn off, it needs to be recycled promptly to facilitate the second clamping member 131 to tear off the side film again. To prevent the torn side film from being carelessly discarded on the production site, affecting the cleanliness of the production site or the normal operation of various mechanisms, please refer to some embodiments of this application. Figure 10 and Figure 11 Below the second tearing position, there is a side film collecting assembly 140. When the second clamping member 131 tears off the side film at the second tearing position, the second clamping member 131 opens, and the side film falls into the side film collecting assembly 140 below the second tearing position under the action of gravity.

[0094] Specifically, the side membrane collection assembly 140 includes a waste membrane recycling bin, which can be used to collect the torn side membrane. Operators only need to clean the waste membrane recycling bin regularly to ensure the cleanliness of the production site, and the side membrane recycling will not affect the normal operation of other mechanisms or components.

[0095] In some embodiments of this application, please refer to Figure 1 The moving path of the conveying end 310 passes through the first tearing position and the second tearing position, which can realize the transfer of the film covering fixture 800 between the first tearing position and the second tearing position, and facilitate the separation of the fixture 810 from the large film 820 and the side film respectively.

[0096] In some preferred embodiments of this application, the fixture loading and unloading mechanism 300 includes a loading and unloading robot. The handling end 810 of the robot can grasp the fixture 810 and move the fixture 810 to the first tearing position or the second tearing position. When the fixture fixing component 150 is stably connected to both ends of the fixture 810, the handling end 810 of the robot separates from the fixture 810 and returns to its original position.

[0097] It should be noted that, in order to avoid interference between the transport end 810 and the workpiece 824 when gripping the fixture 810, it is preferable that the transport end 810 grips the back of the fixture 810. At this time, the fixture fixing components 150 at both ends of the first and second tearing positions are connected to the flipping component 120. After the fixing ends 151 at both ends of the first tearing position are stably connected to both ends of the fixture 810, the fixture 810 can be rotated by the flipping component 120 to rotate the workpiece 824 from a vertically downward position to a vertically upward position, which facilitates the subsequent separation of the large film 820 and the fixture 810.

[0098] After separating the large film 820 and the fixture 810, the large film 820 carrying a large number of workpieces 824 can be transferred from the film tearing mechanism 100 to the workpiece separation mechanism 200 by the transfer mechanism 400.

[0099] Specifically, the transfer mechanism 400 includes a gantry frame 450 and X-axis sliding modules 430, Y-axis sliding modules 440, and Z-axis sliding modules 420 mounted on the gantry frame 450. The mounting base 412 of the film lifting end 410 is connected to the Z-axis sliding module 420, allowing the film lifting end 410 to be raised and lowered. The Z-axis sliding module 420 is connected to the X-axis sliding module 430, driving the Z-axis sliding module 420 and the film lifting end 410 to slide in the X-axis direction. Two sets of X-axis sliding modules 430 are mounted on the same sliding beam, which is connected to the Y-axis sliding module 440. The Y-axis sliding module 440 drives the sliding beam to move in the Y-axis direction, thereby causing the X-axis sliding module 430, the Z-axis sliding module 420, and the film lifting end 410 to move as a whole in the Y-axis direction. When the lifting end 410 has X and Z displacement, it can cooperate with the auxiliary film tearing assembly 110 to separate the large film 820 from the fixture 810. When the lifting end 410 has X, Y and Z displacement, it can clamp the large film 820 carrying the workpiece 824 to achieve transfer.

[0100] It should be noted that the existing separation method for workpiece 824 basically involves adsorbing workpiece 824 using a suction cup assembly, then directly lifting the suction cup assembly using a lifting component to move workpiece 824 upwards and tear it apart from the large film 820. In actual operation, this separation method causes the large film 820 to be pulled to a high position, resulting in low separation efficiency and potentially causing displacement of other workpieces 824 on the large film 820, which is detrimental to the subsequent separation of the remaining workpieces 824. Simultaneously, during this tearing separation process, the upper and lower surfaces of workpiece 824 must withstand the pulling forces from both the suction cup assembly and the large film 820. The pulling force applied by the suction cup assembly is mainly concentrated in the middle of workpiece 824, directed vertically upwards, while the pulling force applied by the large film 820 is located at the peeling openings on both sides of workpiece 824, directed vertically downwards or inclined downwards. This can easily lead to breakage or damage in the middle or on the sides of workpiece 824, which is detrimental to ensuring product yield.

[0101] To address the aforementioned issues, please refer to some embodiments of this application. Figure 1 and Figure 13 The workpiece separation mechanism 200 includes a film placement platform 210 disposed at the workpiece picking station, and a picking and placing assembly 220 and a film transfer assembly 230 movably disposed corresponding to the film placement platform 210. For example... Figure 13 As shown. Specifically, the pick-and-place component 220 is movably disposed at one end of the film placement platform 210. During the separation of workpiece 824, the film transfer component 230 drives the large film 820 to move as a whole, so that the workpieces 824 on the large film 820 approach the pick-and-place component 220 row by row, making it easier for the pick-and-place component 220 to remove the workpieces 824 carried on the large film 820 row by row. The pick-and-place component 220 can form a connection with the workpiece 824 during separation, and the film transfer component 230 can drive the large film 820 to move smoothly away from the workpiece 824, allowing the large film 820 to be peeled off from one side of the workpiece 824. This helps improve the stress state of the workpiece 824 during the film peeling process, ensuring the film peeling effect without affecting the pick-and-place position of other workpieces 824, and thus improving the separation efficiency of the workpieces 824 carried on the large film 820.

[0102] In some embodiments of this application, please refer to Figure 14 The pick-and-place assembly 220 has multiple adjustable pressing ends 2221 and pick-up ends 2211, with each pressing end 2221 corresponding to one of the pick-up ends 2211. The pick-up ends 2211 can be used to simultaneously pick up and place multiple workpieces 824 in the same row, which helps improve the tear-off and separation efficiency of the workpieces 824. The pressing ends 2221 can be used to press down on the large film body 822 at the front end of the multiple workpieces 824 arranged in the same row, preventing the large film 820 at the front end of the workpieces 824 from bulging (or arching) and affecting the separation operation between the workpieces 824 and the large film body 822.

[0103] Specifically, the pick-and-place assembly 220 includes a workpiece pick-and-place module 221 and a pressing module 222; wherein, the workpiece pick-and-place module 221 includes multiple pick-and-place ends 2211, and the pressing module 222 includes multiple pressing ends 2221.

[0104] It should be noted that the picking end 2211 can connect with the workpiece 824 through adsorption or clamping. To avoid interference between the workpiece 824 on the picking end 2211 and the workpiece 824 on the large film 820 behind it during the movement of the large film 820, the picking and placing component 220 moves synchronously with the large film 820 during the film peeling process of the workpiece 824, and there is always a workpiece peeling opening between the workpiece 824 and the large film body 822, such as... Figure 23 As shown. Preferably, in order to improve the stress state of workpiece 824 during the film-tearing process, the pick-and-place assembly 220 moves along the film-tearing process of workpiece 824. Figure 23 The horizontal movement from right to left allows the large film body 822 to be peeled off from the left side of the workpiece 824. The side peeling method improves the stress on the workpiece 824, prevents the workpiece 824 from breaking, and improves the film peeling and separation efficiency of the workpiece 824 while also improving the yield of the workpiece 824.

[0105] In some embodiments of this application, please refer to Figure 14 To enable lifting and adjusting of the picking end 2211 and the pressing end 2221, the workpiece picking and placing module 221 further includes a fourth driving component 2212 connected to the picking end 2211, and the pressing module 222 further includes a fifth driving component 2222 connected to the pressing end 2221. Specifically, the fourth driving component 2212 and the fifth driving component 2222 can be driving components such as lifting cylinders or lifting hydraulic cylinders.

[0106] In the existing large membrane 820, if the large membrane body 822 is not adhesive, then the large membrane 820 includes not only the large membrane body 822 and multiple workpieces 824, but also a small membrane 823 disposed between the large membrane body 822 and the workpieces 824. The upper and lower surfaces of the small membrane 823 are adhesive, and its main body size is the same as that of the workpieces 824. The workpieces 824 can be adhered to the large membrane body 822 through the small membrane 823. To facilitate the separation of the small membrane 823 from the workpieces 824, a small membrane ear protruding from the front end of the workpiece 824 is provided at the front end of the small membrane 823, such as... Figure 7 As shown. When the film is peeled off the workpiece 824, both the small film 823 and the large film body 822 need to be separated from the workpiece 824, as follows. Figure 23 As shown, at this time, the workpiece peeling opening needs to be formed between the workpiece 824 and the small film 823.

[0107] To address the aforementioned issues, in some embodiments of this application, the pressure end 2221 matches the small membrane ear at the front end of the small membrane 823. The pressure end 2221 can press down the small membrane ear, causing the small membrane 823 to form a workpiece separation opening with the workpiece 824 at the small membrane ear. Figure 23 As shown. After the film is removed from the workpiece 824, the small film 823 remains adhered to the large film body 822 and moves synchronously with the large film body 822 in a direction away from the workpiece 824.

[0108] Preferably, the pressure end 2221 is a pressure plate. When the workpiece 824 peels off the film, the bottom end of the pressure plate presses down on the small film ear, forming a workpiece peeling opening between the small film 823 and the workpiece 824. In order to enable the pressure plate to press down accurately on the small film ear, the pressure module 222 also includes a sixth driving member 2223 connected to the fifth driving member 2222 and the pressure end 2221 respectively. The sixth driving member 2223 is a rotary driving member that can drive the pressure plate to rotate, thereby aligning the pressure plate with the small film ear, increasing the contact area between the pressure plate and the small film ear, and facilitating effective pressing down on the small film ear.

[0109] In some embodiments of this application, please refer to Figure 14 The pick-and-place assembly 220 includes a vision positioning module 224 that is signal-connected to the pressing end 2221 and the pick-up end 2211. This facilitates the positioning of the workpiece 824 and the small membrane ear through the vision positioning module 224, and enables the working ends of the workpiece pick-and-place module 221 and the pressing module 222 to achieve precise movements.

[0110] In some embodiments of this application, the visual positioning module 224 includes multiple CCD cameras, which are correspondingly set with the pick-up end 2211 and the pressing end 2221. They can be used to position multiple workpieces 824 or small membrane ears in the same row. The driving components in the workpiece pick-up and place module 221 and the pressing module 222 can be independently adjusted according to the positioning information, which facilitates precise positioning of each small membrane ear or workpiece 824. This allows the pick-up end 2211 to accurately adsorb or clamp the workpiece 824, and the pressing end 2221 to accurately press down the small membrane ear at the front end of the workpiece 824, so that a workpiece peeling opening is created between the small membrane 823 and the workpiece 824.

[0111] In some embodiments of this application, please refer to Figure 17 The film transfer assembly 230 includes a first film clamping module 231 and a second film clamping module 232 distributed at both ends of the film placement platform 210, used to clamp the front and rear ends of the large film 820. During the peeling process of the workpiece 824, the first film clamping module 231 and the second film clamping module 232 clamp the large film 820 and move it smoothly relative to the film placement platform 210. It can cooperate with the pick-and-place assembly 220 to peel the large film 820 from one side of the workpiece 824, such as... Figure 23As shown. During the movement of the large membrane 820, the first clamping module 231 and the second clamping module 232 always clamp the large membrane 820, so that the arrangement position of the workpieces 824 on the membrane placement platform 210 remains stable. This can prevent the placement and removal positions of other workpieces 824 from shifting due to the placement and removal of the front workpieces 824, which is beneficial to improving the separation efficiency of the workpieces 824.

[0112] It should be noted that, in the initial state, the first clamping module 231 and the second clamping module 232 are distributed at the front and rear ends of the film placement platform 210, with the first clamping module 231 closer to the pick-and-place component 220. The first clamping module 231 clamps the front end of the large film body 822, and the second clamping module 232 clamps the rear end of the large film body 822, which carries multiple workpieces 824. During the film removal process of workpiece 824, the first film clamping module 231 moves away from the workpiece pick-up and drop module 221 and also away from the front end of the film placement platform 210. The direction of moving away can be vertically downward or inclined downward. Meanwhile, the second film clamping module 232 moves from the rear end of the film placement platform 210 to the front end of the film placement platform 210 as the large film 820 moves. At this time, the positions of the first film clamping module 231 and the second film clamping module 232 relative to the film placement platform 210 will change, but the large film 820 will always remain taut under the clamping of the first film clamping module 231 and the second film clamping module 232.

[0113] In some embodiments of this application, please refer to Figure 17 , Figure 18 and Figure 19 The first clamping module 231 includes a first clamping end 2311, a lifting plate 2312, a sliding seat 2313, and a second lifting drive 2314. Multiple first clamping ends 2311 are sequentially arranged on the lifting plate, with their clamping openings facing the film placement platform 210 to facilitate the insertion of the front end of the large film 820 into the clamping opening. The number of first clamping ends 2311 and the distance between adjacent first clamping ends 2311 are set according to the width of the large film 820 to ensure stable clamping of the front end of the large film 820. The lifting plate 2312 is slidably mounted vertically on the sliding seat 2313 and connected to the second lifting drive 2314, allowing the lifting plate 2312 to move vertically relative to the sliding seat 2313. After the large film 820 is clamped at the front end of the first clamping end 2311, the large film body 822 and the small film 823 can be driven away from the workpiece 824 by the second lifting drive component 2314 and the first clamping end 2311, so that the workpiece 824 can be peeled off.

[0114] It should be noted that, in order to keep the large film body 822 and the small film 823 away from the workpiece 824 fixed by the picking end 2211, the first clamping end 2311 on the first clamping module 231 can move vertically downward continuously, or it can move downward first and then move horizontally, so that the large film body 822 moves downward at an angle, ensuring that the workpiece peeling opening is always present. When the large film 820 is long (e.g., more than 1 meter), it is preferable to use the second lifting drive 2314 to lower the lifting plate 2312 and multiple first clamping ends 2311 as a whole to below the guide film structure 211, and then use the sliding seat 2313 to drive the lifting plate 2312 and the first clamping ends 2311 to slide horizontally towards the rear end of the film placement platform 210 (i.e., Figure 23 (From left to right in the middle), at this time, the workpiece pick-and-place module 221 and the first film clamping module 231 move in opposite directions, which is more conducive to tearing off the large film body 822 and the small film 823 away from the workpiece 824, such as Figure 23 and Figure 22 As shown. To achieve horizontal sliding of the first film clamping module 231, the film transfer assembly 230 also includes a first sliding module 330 connected to the first film clamping module 231, as shown. Figure 17 , Figure 18 and Figure 19 As shown.

[0115] In some embodiments of this application, please refer to Figure 17 and Figure 20 The second clamping module 232 includes multiple second clamping ends 2321 distributed on both sides of the film placement platform 210, which can clamp the rear ends of the large film 820 and avoid interference with the components located in the middle of the film placement platform 210. The multiple second clamping ends 2321 can move synchronously, which can ensure the stability of the movement of the large film 820 and prevent the large film 820 from wrinkling or being stretched due to asynchronous movement of the second clamping ends 2321 on both sides.

[0116] In some embodiments of this application, please refer to Figure 20The film transfer assembly 230 also includes a second sliding module 234 connected to the second film clamping module 232. The second sliding module 234 includes a tenth driving member 2341, a linkage member 2342, a transmission assembly 2343, and a second slide rail 2344. The tenth driving member 2341 is connected to the transmission assemblies 2343 on both sides of the film placement platform 210 via the linkage member 2342, enabling synchronous driving of the transmission assemblies 2343 on both sides. The transmission assemblies 2343 on both sides of the film placement platform 210 are respectively connected to the second film clamping ends 2321 on both sides of the film placement platform 210, driving the second film clamping ends 2321 to slide reciprocally along the second slide rail 2344. By synchronously driving the second film clamping ends 2321 on both sides of the film placement platform 210 with the tenth driving member 2341, the number of driving members can be reduced, which helps to reduce equipment costs. Specifically, the transmission assembly 2343 can be a belt drive assembly or a chain drive assembly, etc.

[0117] In some embodiments of this application, please refer to Figure 21 The second film clamping module 232 also includes an eighth driving member 2322, a ninth driving member 2323, and a connecting seat 2324, which are correspondingly arranged with respect to the second film clamping end 2321. The eighth driving member 2322 is a lifting cylinder or lifting hydraulic cylinder, and the ninth driving member 2323 is a horizontal cylinder or horizontal hydraulic cylinder, which allows the second film clamping end 2321 to move vertically and horizontally, facilitating adjustment of the film clamping position. The connecting seat 2324 is used to connect with the transmission assembly 2343 and the second slide rail 2344, and can drive the eighth driving member 2322, the ninth driving member 2323, and the second film clamping end 2321 to move as a whole along the length of the film placement platform 210.

[0118] In some embodiments of this application, please refer to Figure 14 , Figure 17 and Figure 18 The pick-and-place component 220 includes a height-adjustable curved film structure 2231, the end of which can be fitted into the clamping opening of the first clamping module 231. When the front end of the large film 820 extends out of the end of the film holder 213, the front end of the large film 820 can be pressed into the clamping opening of the first clamping module 231 through the curved film structure 2231, facilitating the clamping of the front end of the large film 820 by the first clamping module 231. Automated clamping can be achieved, eliminating the need for manual placement of the front end of the large film 820 into the clamping opening of the first clamping module 231, thereby improving the automation level of the workpiece separation mechanism and enhancing the separation efficiency of the workpiece 824.

[0119] In some embodiments of this application, please refer to Figure 14The bending module 223 in the pick-and-place assembly 220 includes a bending structure 2231 and a seventh drive component 2232. The seventh drive component 2232 is a drive component such as a lifting cylinder or a lifting hydraulic cylinder, which can be used to drive the bending structure 2231 to move in the vertical direction. After the film clamping is completed, the bending structure 2231 is lifted, which can avoid interference with the subsequent film tearing process.

[0120] In some embodiments of this application, please refer to Figure 16 , Figure 18 and Figure 23 The membrane placement platform 210 is equipped with an adjustable membrane guide structure 211 at one end near the pick-and-place component 220. The membrane guide structure 211 is oriented towards the first membrane clamping module 231, which can reduce the frictional force generated when the first membrane clamping module 231 moves the large membrane 820 relative to the front end of the membrane placement platform 210.

[0121] The membrane guide structure 211 is movably disposed in the membrane placement frame 213 at the front end of the membrane placement platform 210, and can extend or retract into the membrane placement frame 213. Figure 16 In the extended state, Figure 18 In the retracted state, when the guide membrane structure 211 retracts into the membrane holder 213, it avoids affecting the front end of the large membrane body 822 held by the first membrane clamping module 231. After the first membrane clamping module 231 completes clamping and moves a certain distance away from the membrane placement platform 210, the guide membrane structure 211 extends from the membrane holder 213, providing support and guidance for the back of the large membrane body 822, causing the large membrane body 822 to bend at the guide membrane structure 211, thus preventing the large membrane body 822 from directly contacting the end face of the membrane holder 213. Figure 23 As shown, this can reduce friction during the movement of the large membrane 820.

[0122] In some preferred embodiments of this application, the film guide structure 211 can be slidably disposed on the film placement frame 213 in a horizontal direction, so that the film guide structure 211 can extend or retract to the front end of the film placement platform 210. The film guide structure 211 includes a rotatably disposed film guide roller, which can further reduce the friction between the film guide structure 211 and the large film body 822, which is beneficial to achieving smooth movement of the large film 820.

[0123] In some embodiments of this application, the top plate of the film holder 213 can be heated. When the large film 820 carrying the workpiece 824 moves onto the film holder 213, the heated top plate can reduce the adhesion between the workpiece 824 and the small film 823, making it easier to separate the workpiece 824 from the small film 823.

[0124] In some embodiments of this application, please refer to Figure 16 and Figure 20The film-laying platform 210 has a movable conveying surface 2121. A large film 820 carrying multiple workpieces 824 can be placed on the conveying surface 2121, which provides stable support for the large film 820. The moving speed of the second film-clamping module 232 is adapted to the moving speed of the conveying surface 2121 to avoid wrinkles or stretching of the large film 820 due to the difference in moving speed between the conveying surface 2121 and the second film-clamping module 232.

[0125] It should be noted that the conveying surface 2121 can be the plane containing the tops of multiple conveying rollers or the top plane of the conveyor belt, both of which can provide stable support for the large film 820. Preferably, since the large film 820 is a flexible structure, to prevent the large film 820 from collapsing when the gap between adjacent conveying rollers is large, a conveying module 212 with a conveyor belt is preferably used to convey the large film 820. Specifically, the conveying module 212 also includes a driving component 2122, which is connected to the conveyor belt with the conveying surface 2121, so that the conveying surface 2121 can move synchronously with the large film 820 and the second film clamping module 232.

[0126] In the above embodiments, to avoid interference between the workpiece 824 at the bottom of the picking end 2211 and the moving large membrane 820, please refer to some embodiments of this application. Figure 15 The pick-and-place component 220 is connected to the moving component 250, and the picking-and-place component 220 is moved relative to the film placement platform 210 by the moving component 250.

[0127] It should be noted that the moving component 250 can be any component capable of causing the pick-and-place component 220 to move horizontally. For some embodiments of this application, please refer to... Figure 14 and Figure 15 The moving component 250 includes a third sliding module 251, a mounting beam 252, a fourth sliding module 253, a third slide rail 254, and a support frame 255. The mounting frame 225 of the pick-and-place component 220 is mounted on the third sliding module 251, allowing the pick-and-place component 220 to move along the width direction of the large film 820, facilitating the alignment of multiple working ends with the workpiece 824 along the width direction of the large film 820. The third sliding module 251 is mounted on the mounting beam 252, which is connected to the fourth sliding module 253 and the third slide rail 254, respectively, enabling the pick-and-place component 220 to move horizontally along the length direction of the large film 820, facilitating the pick-and-place component 220 to approach or move away from the film placement platform 210. The fourth sliding module 253 and the third slide rail 254 are mounted on the support frame 255 to raise the overall height of the pick-and-place assembly 220, so that the pick-and-place assembly 220 is located above the film placement platform 210, which facilitates the tearing and removal of the large film 820 on the film placement platform 210.

[0128] After the separation of workpiece 824 from the large membrane body 822 is completed, the waste membrane needs to be recycled. Please refer to the figures for some embodiments of this application. Figure 19 , Figure 24 and Figure 25 The workpiece separation mechanism 200 also includes a recycling component 240 disposed below the film placement platform 210. After all workpieces 824 on the large film 820 are removed, the first film clamping module 231 moves the large film body 822 and the small film 823 (i.e., waste film) as a whole to below the film placement platform 210. After the first film clamping module 231 and the second film clamping module 232 are released, the waste film falls onto the recycling component 240 below the film placement platform 210, thus achieving waste film recycling. It can be understood that the movement paths of the first film clamping module 231 and the second film clamping module 232 are adapted to the waste film recycling path, facilitating the recycling of the waste film along a predetermined path.

[0129] It should be noted that the recycling component 240 can be a recycling bin located below the film placement platform 210, but if multiple layers of waste film fall into the recycling bin in a messy manner, it will result in a large amount of wasted space inside the recycling bin, and the number of waste films that can be recycled will be limited.

[0130] To avoid the above problems, please refer to some embodiments of this application. Figure 24 and Figure 25 The recycling component 240 includes a recycling platform 241 movably disposed below the film placement platform 210 and clamping modules 242 distributed around the recycling platform 241. During waste film recycling, the recycling platform 241 moves closer to the film placement platform 210 under the action of the lifting component, placing the waste film held by the first clamping module 231 and the second clamping module 232 onto the recycling platform 241. The clamping modules 242 around the recycling platform 241 clamp the edges of the waste film. Subsequently, the first clamping module 231 and the second clamping module 232 release, and the recycling platform 241 moves downwards carrying the waste film, avoiding interference with the resetting of the first clamping module 231. This waste film recycling method allows for the regular stacking and fixing of a large amount of waste film, which is beneficial for increasing the recycling capacity of the recycling component 240.

[0131] In some embodiments of this application, please refer to Figure 12 and Figure 22 The multi-workpiece batch operation equipment also includes a worktable 600, one or more workpiece separation mechanisms 200 are disposed on the worktable 600, and a recycling component 240 is disposed inside the worktable 600. To allow waste film to fall into the recycling component 240 inside the worktable 600, a through-feed port 610 is provided on the worktable body 620. Figure 24 , Figure 12 and Figure 22 As shown.

[0132] In some preferred embodiments of this application, the film-tearing mechanism 100 and multiple workpiece separation mechanisms 200 are arranged on the workbench 600. By having multiple workpiece separation mechanisms 200 work simultaneously, production efficiency can be greatly improved. The transfer mechanism 400 can act on the feeding end of multiple workpiece separation mechanisms 200 to transfer the large film 820 carrying the workpiece 824 to each workpiece separation mechanism.

[0133] In some embodiments of this application, please refer to Figure 26 and Figure 27 The multi-workpiece batch operation equipment also includes a coating mechanism 500, which is located near the output end of the workpiece separation mechanism 200 and is used to perform single-sided or double-sided coating operations on the workpieces 824 output by the workpiece separation mechanism 200.

[0134] Specifically, the coating mechanism 500 has an inspection channel, a defective workpiece channel, and a coating station, with the coating station located at the feed end of the inspection channel. Workpieces 824 removed from the large film 820 undergo defect inspection in the inspection channel. If defects are found on the surface of workpiece 824, it must be transferred to the defective workpiece channel. Other qualified workpieces 824 can smoothly pass through the feed end of the inspection channel and enter the coating station for coating operations.

[0135] In some embodiments of this application, please refer to Figure 26 and Figure 27 The coating mechanism 500 also includes a detection module 510 and a conveying module 520 connected by signals. The detection module 510 is configured to detect the workpiece 824 in the detection channel to confirm whether the workpiece 824 has appearance defects or waste film residue. The conveying module 520 moves between the detection channel and the defective workpiece channel to transfer the defective workpiece 824 from the detection channel to the defective workpiece channel, such as... Figure 26 As shown.

[0136] In some embodiments of this application, the laminating mechanism 500 further includes a frame 530, on which both the detection module 510 and the transport module 520 are movably mounted. Specifically, the detection module 510 can reciprocate along the width of the detection channel to detect multiple workpieces 824 arranged side-by-side on the detection channel one by one, preventing defective workpieces 824 from flowing into the laminating station. The transport module 520 includes a transfer end 521 and a sliding assembly 522, wherein the sliding assembly 522 is connected between the frame 530 and the transfer end 521, allowing the transfer end 521 to slide relative to the frame 530, such as... Figure 27 As shown, this allows defective workpiece 824 on the detection channel to be transferred to the defective workpiece channel.

[0137] In some embodiments of this application, please refer to Figure 26The coating mechanism 500 also includes a coating module 540, a conveying module 550, and a receiving module 560. The coating module 540 has multiple coating stations and can be used to coat multiple workpieces 824 simultaneously. The receiving module 560 is located at the output end of the coating module 540 and is used to receive and store the coated workpieces 824. The conveying module 550 is located in the defective workpiece channel and is used to convey the defective workpieces 824 to the defective workpiece 824 processing station.

[0138] In some embodiments of this application, please refer to Figure 1 , Figure 12 and Figure 22 The multi-workpiece batch operation equipment also includes a workpiece loading and unloading mechanism 700, which is located at the delivery end of the workpiece separation mechanism 200. The support frame 255 of the moving component 250 is located above the workpiece loading and unloading mechanism 700. The pick-and-place component 220 can place the workpiece 824 adsorbed or gripped by the pick-up end 2211 onto the workpiece loading and unloading mechanism 700. The workpiece 824 removed from the workpiece separation mechanism 200 is transported to the detection channel of the coating mechanism 500 through the workpiece loading and unloading mechanism 700.

[0139] It should be noted that in this application, the workpiece loading and unloading mechanism 700 can simultaneously realize the unloading of the workpiece separation mechanism 200 and the loading of the coating mechanism 500. The detection channel can be directly connected to the workpiece loading and unloading mechanism 700, or it can be indirectly connected through other mechanisms with transmission functions.

[0140] In some embodiments of this application, the coating mechanism 500 further includes an auxiliary feeding module, which includes a variable-pitch suction nozzle. When the workpiece spacing of the workpiece loading / unloading mechanism 700 or other mechanisms with transmission functions does not match the workpiece spacing of the detection channel, the auxiliary feeding module can first remove the workpiece 824 from the workpiece loading / unloading mechanism 700 or other mechanisms with transmission functions, and then adjust the spacing between adjacent workpieces 824 with the variable-pitch suction nozzle to match the detection channel, and then place the workpiece 824 on the detection channel.

[0141] Please see Figures 1 to 27 In some embodiments of this application, the operation method of the above-mentioned multi-workpiece batch operation equipment is as follows:

[0142] Step 1: The film-coating fixture 800 is moved from the loading area to the second film-tearing position by the conveying end 810 of the fixture loading and unloading mechanism 300. The side film is removed from both sides of the fixture 810 by the cooperation of the side film tearing assembly 130 and the flipping assembly 120.

[0143] Step 2: The flipping components 120 at both ends of the second film-tearing position rotate the fixture 810 to the back-facing position. The fixture loading and unloading mechanism 300 grabs the back of the fixture 810 and moves the fixture 810 with the large film 820 pasted on it to the first film-tearing position.

[0144] Step 3: After the fixed ends 151 on both sides of the first tearing position are stably connected to the fixture 810, the flipping components 120 at both ends of the first tearing position are activated, causing the fixture 810 of the first tearing position to rotate to the state where the workpiece 824 is vertically facing upward.

[0145] Step 4: The lifting end 410 clamps and lifts both ends of the large film 820, so that a tearing opening is formed between the large film 820 and the fixture 810. The auxiliary tearing components 110 at both ends of the first tearing position move towards each other. The separating member 111 extends into the tearing opening. When the lifting end 410 moves relative to the first tearing position, the separating member 111 pushes the back of the large film 820 to separate the large film 820 from the fixture 810.

[0146] Step 5: The lifting end 410 moves relative to the gantry 450, moving the large film 820 carrying a large number of workpieces 824 onto the film placement platform 210 of the workpiece separation mechanism 200, so that the front end of the large film 820 extends beyond the front end of the film placement platform 210. The fixture loading and unloading mechanism 300 moves the fixture 810, after removing the large film 820 and the side films, to the unloading area, facilitating the fixture 810 to enter the next round of circulation.

[0147] Step Six: The second membrane clamping module 232 clamps the rear end of the large membrane 820. The pick-and-place component 220 moves, positioning the curved membrane structure 2231 above the front end of the large membrane 820. The curved membrane structure 2231 descends, pressing the front end of the large membrane 820 into the clamping opening of the first membrane clamping module 231, thus clamping the front end of the large membrane 820. The curved membrane structure 2231 rises to its original position, and the first membrane clamping module 231 descends, tensioning the large membrane 820 and causing the first row of small membrane ears on the large membrane 820 to extend out from the front end of the membrane holder 213.

[0148] Step 7: The vision positioning module 224 takes pictures of the workpiece 824 and the small membrane ear for positioning. The pick-up and place component 220 adjusts its position according to the positioning information so that the pick-up end 2211 is above the workpiece 824 and the pressing end 2221 is above the small membrane ear.

[0149] Step 8: The pressing module 222 is activated, the pressing end 2221 presses down, so that a workpiece peeling opening is formed between the small film 823 and the workpiece 824; the picking end 2211 picks up the workpiece 824.

[0150] Step Nine: The first film clamping module 231, the second film clamping module 232, and the conveying surface 2121 move synchronously at an appropriate moving speed; the pick-and-place assembly 220 moves horizontally away from the film placement platform 210 and the second film clamping module 232, and the large film body 822 and the small film 823 are torn off from one side of the workpiece 824 under the combined action of the pick-and-place assembly 220 and the film transfer assembly 230, as shown. Figure 23 As shown.

[0151] Step 10: The pick-and-place assembly 220 moves above the workpiece loading / unloading mechanism 700, and the pick-up end 2211 descends to place the workpiece 824 on the workpiece loading / unloading mechanism 700, allowing the workpiece 824 to flow to the coating mechanism 500. The pick-and-place assembly 220 then moves toward the film placement platform 210 again to pick up the next row of workpieces 824.

[0152] Step 11: The inspection module 510 performs defect inspection on the workpiece 824 entering the inspection channel. When a defect is found in the workpiece 824, the defective workpiece 824 is transferred from the inspection channel to the defective workpiece channel by the transfer module 520. The workpiece 824 that passes the inspection enters the coating station, and after the coating operation is performed by the coating module 540, it falls into the storage module 560.

[0153] Step 12: After all workpieces 824 on the large membrane 820 have been picked up and placed, the large membrane body 822 and the small membrane 823 (i.e., waste membrane) are located below the membrane placement platform 210. The recycling platform 241 rises to receive the waste membrane, and the clamping modules 242 on the periphery of the recycling platform 241 clamp the waste membrane. Then, the first clamping module 231 and the second clamping module 232 release, and the recycling platform 241 descends to complete the waste membrane recycling.

[0154] It should be noted that in the above operation method, the order of tearing the large film 820 and the side film on the same fixture 810 can be changed, and there is no limitation here.
