Description

Lamination device for thin-sheet products

Technical Field

The invention relates to the technical field of semiconductor product processing equipment, and in particular to a layering device for thin-sheet products.

Background technique

In semiconductor automation equipment, automatic loading mechanisms for thin products such as liquid crystal displays, silicon wafers, and copper sheets are frequently used. The main function of the automatic loading mechanism is to pick up a single product from a pile of incoming materials from the previous process and transfer it to the next process for processing.

There are two main ways for product materials to come in: trays and silos. For silos, hundreds of sheets of material are stacked into a pile, which is prone to two or more layers of stacked materials. However, actual production requires single-sheet material. If the stacked materials are used for production, the product will inevitably be unqualified or even damaged. Therefore, the automatic loading of the silo needs to be equipped with a layering device for thin-sheet products.

The existing thin-sheet product layering device mainly adopts the air-blowing layering method, that is, blowing air between the two thin-sheet products on the top layer to separate the top-layer product. This method is mainly suitable for layering thin or flexible products, but for products with a harder texture and metal sheets that are bonded due to vacuum or stains between products, the layering effect is not ideal, and the high stacking rate affects production efficiency.

Detailed ways

In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

1 , this embodiment provides a device for layering thin sheet products, including a base frame 1 , a supporting mechanism 2 , a positioning column 3 , a high-position detection mechanism 4 , a pressing mechanism 5 and a material shifting mechanism 6 .

The base frame 1 is mainly used to provide hardware support for other components.

1 and 2 , the support mechanism 2 is mainly used to support and drive the product to rise and fall. The support mechanism 2 includes a lifting drive member 21 and a support plate 22. The fixed portion of the lifting drive member 21 is fixed on the base frame 1, and the support plate 22 is fixed to the top of the lifting drive member 21 and is suitable for supporting the product.

Specifically, the lifting drive 21 adopts a lifting motor, which includes a housing and an output shaft capable of outputting a linear lifting motion, the housing is fixed below the base frame 1, the output shaft passes through the base frame 1 upward and is fixedly connected to the support plate 22, and the lifting motor moves to realize the lifting of the support plate 22. In other embodiments, the lifting drive 21 can adopt a cylinder or a linear push rod or other commonly used linear power elements.

More specifically, the lifting motor is a double-axle extension motor, that is, both ends of the output shaft of the lifting motor extend outward from the casing to form an extension section. The upper extension end passes through the base frame 1 and is fixedly connected to the support plate 22. An induction plate is fixed on the lower extension end. A fixed column 16 is also provided under the base frame 1. Sensors for detecting induction plate signals are provided at the upper and lower ends of the fixed column 16. The induction plate cooperates with the two sensors to control the upper limit position and the lower limit position of the lifting motor to ensure the safety of the operation of the lifting motor.

Furthermore, the support plate 22 is connected to the base frame 1 through four sets of guide rods 24 to ensure the stability and accuracy of the lifting and lowering action of the support plate 22.

Furthermore, a photoelectric sensor 23 is provided on the support plate 22 for detecting whether there is a product above the support plate 22, and the photoelectric sensor 23 is connected to the lifting drive 21. During operation, the lifting drive 21 is controlled to move only after the photoelectric sensor 23 obtains a product signal, which can avoid the generation of redundant and invalid actions and waste of equipment resources.

1 and 3 , the positioning column 3 is mainly used to limit the position of the product to ensure that a stack of products is basically neat. The positioning column 3 is fixed on the base frame 1 . There are multiple positioning columns 3 and they are all arranged vertically. The multiple positioning columns 3 are in a working state distributed around the support plate 22 .

Specifically, eight positioning posts 3 are provided. In other embodiments, four or six positioning posts 3 may also be provided, and the specific number may be determined according to the size and shape adaptability of the product.

1 and 2 , the high-position detection mechanism 4 includes a high-position sensor 41, which is mounted on the base frame 1 and is suitable for detecting the height of the product on the support plate 22. The high-position sensor 41 is communicatively connected with the lifting drive 21 to control the product on the support plate 22 to rise to a target height.

Specifically, the high-position sensor 41 is fixed to the base frame 1 through the sensor bracket 42 , that is, the bottom of the sensor bracket 42 is fixed to the base frame 1 , and the high-position sensor 41 is fixed to the top of the sensor bracket 42 .

1, 3 and 4, the clamping mechanism 5 includes a horizontal driving member 51 and a damping block 52, the fixing portion of the horizontal driving member 51 is fixed on the base frame 1, and the damping block 52 is fixed on the output end of the horizontal driving member 51, and the horizontal driving member 51 is suitable for driving the damping block 52 to move so as to push the product to the opposite positioning column 3 for fixation when the positioning column 3 is in a working state and the product rises to a target height.

It is easy to understand that when the material-digging mechanism 6 is in action, the top first layer of products contacts the material-digging mechanism 6 and moves upward under force. If the top second layer of products is not fixed, the top second layer of products is very likely to be lifted up along with the top first layer of products under the action of the interlayer suction force, which loses the meaning of separation and still causes lamination. Therefore, the layering device of this embodiment first pushes the products to the opposite side positioning column 3 through the damping block 52 to achieve fixation before diverting the materials, and then performs the material-diverting action, so as to ensure that only the top layer of products under force will be removed.

It is easy to understand that the damping block 52 needs to be set corresponding to the gap of the positioning column 3 so that it can contact the product after passing over the positioning column 3. The damping block 52 extends into the gap of the positioning column 3 on one side of the product, and pushes the product to the other side of the product after contacting the product. The aforementioned "opposite side" refers to the opposite side of the side where the damping block 52 is located based on the product.

It should be noted that, in theory, the damping block 52 only needs to fix the second layer on the top, but due to the thinness of the product, it is difficult to design an appropriate size of the damping block 52, and the position accuracy of the damping block 52 is also too high. Therefore, in actual use, the design parameters of the damping block 52 can meet the requirements of pushing and fixing the top multi-layer products, and do not need to correspond to only the second layer on the top, nor do they need to correspond to all the products in a stack.

It should be noted that the damping block 52 is made of elastic materials such as rubber and silicone. The elastic material can prevent the product from being damaged by excessive extrusion force, and can also ensure that the top layer of the product can be removed under the force of the material removal mechanism 6.

Specifically, the horizontal driving member 51 is a telescopic cylinder. In other embodiments, the horizontal driving member 51 can also be a linear push rod or other commonly used linear power elements.

Specifically, the horizontal driving member 51 is fixed to the base frame 1 through the clamping bracket 53 , that is, the bottom of the clamping bracket 53 is fixed to the base frame 1 , and the fixing portion of the horizontal driving member 51 is fixed to the top of the clamping bracket 53 .

Wherein, referring to Figures 1, 3, 5 to 7, the material-pickling mechanism 6 includes a material-pickling driving member 61 and a material-pickling tooth 62. The fixed part of the material-pickling driving member 61 is fixed on the base frame 1, and the material-pickling tooth 62 is installed on the output end of the material-pickling driving member 61. The material-pickling driving member 61 is suitable for driving the material-pickling tooth 62 to move so as to remove the top layer of products when the products rise to the target height.

It is easy to understand that the stripping teeth 62 strip the top product, that is, the stripping teeth 62 only contact the side wall of the top product when in action, and then the stripping teeth 62 move upward to drive the top product upward, thereby separating the top product from its adjacent lower product.

It is easy to understand that the material-moving teeth 62 need to be arranged corresponding to the gap of the positioning column 3 so as to be able to pass over the positioning column 3 and contact the product.

Specifically, the material-moving driving member 61 includes a horizontal telescopic driving member 611, an articulated seat 612 and a material-moving rod 613. The articulated seat 612 is fixed to the end of the output shaft of the horizontal telescopic driving member 611. The material-moving rod 613 includes a rod body 6131 and a first bending rod 6132 and a second bending rod 6133 respectively located at both ends of the rod body 6131. The first bending rod 6132 and the second bending rod 6133 are both bent downwardly toward the rod body 6131. The first bending rod 6132 is hinged on the articulated seat 612 and an angle limiting structure 614 is provided between the first bending rod 6132 and the articulated seat 612. The angle limiting structure 614 is suitable for keeping the rod body 6131 horizontal under the action of gravity torque. The second bending rod 6133 is arranged at an acute angle to the rod body 6131. A plurality of material-moving teeth 62 are provided and distributed along the length direction of the second bending rod 6133. During operation, the rod body 6131 of the material-dispensing rod 613 always remains horizontal under the action of the angle limiting structure 614, and the action of the horizontal telescopic driving member 611 drives the material-dispensing rod 613 to continuously approach the product until the material-dispensing tooth 62 contacts the top product. At this time, the horizontal telescopic driving member 611 continues to act to cause the material-dispensing rod 613 to rotate upward around the hinge seat 612, thereby driving the top product to separate from the adjacent lower product, thereby achieving separation. The material-dispensing driving member 61 of this embodiment, after the material-dispensing tooth 62 contacts the product, can automatically rotate upward under the action of the horizontal driving force to complete the separation, and the structural design is ingenious, the performance is reliable, and the design difficulty is relatively low. In other embodiments, the material-dispensing driving member 61 can also adopt a combination of horizontal drive and vertical drive, that is, first drive the material-dispensing tooth 62 to move horizontally until it contacts the top product, and then drive the material-dispensing tooth 62 to move vertically upward to complete the separation of the top product.

It is easy to understand that since the high-position sensor 41 can accurately control the height of the product rise, that is, it can accurately control the height position of the top product, and at the same time the material-pickup tooth 62 is arranged on an inclined surface along the second bending rod 6133, through the position design of the material-pickup drive 61 and the size design of the material-pickup tooth 62, when the horizontal telescopic drive 611 is in motion, it can control the material-pickup tooth 62 to only contact with the top product, thereby completing the removal of the top product.

More specifically, the material-digging mechanism 6 further includes a material-digging bracket 63, which is mounted on the base frame 1, the fixing portion of the material-digging driving member 61 is fixed on the material-digging bracket 63, and the hinge seat 612 is slidably connected to the material-digging bracket 63. The material-digging bracket 63 can realize the connection between the material-digging driving member 61 and the base frame 1 on one hand, and can support the hinge seat 612 on the other hand to ensure the straightness of the horizontal movement of the material-digging rod 613.

More specifically, the angle limiting structure 614 includes a first inclined surface provided at the bottom of the first bending rod 6132 and a second inclined surface provided on the hinge seat 612. When the rod body 6131 is horizontal, the first inclined surface contacts the second inclined surface to achieve angle limiting. In other embodiments, a stop ear may be provided on the first bending rod 6132, and a stop rod may be provided on the hinge seat 612. When the rod body 6131 is horizontal, the stop ear contacts the stop rod to achieve angle limiting.

In addition, referring to FIG. 1 to FIG. 3 , the layering device of this embodiment also proposes an improved solution, which is as follows:

The bottom frame 1 includes a bottom plate 11, a slide rail 12 and a material plate 13. The slide rail 12 is fixed on the bottom plate 11. The material plate 13 is parallel to the bottom plate 11 and slidably connected to the slide rail 12. The fixed part of the lifting drive member 21 is fixed relative to the bottom plate 11. The material plate 13 is provided with a window 131 suitable for avoiding the lifting of the support plate 22. The positioning columns 3 are fixed on the material plate 13 and distributed around the window 131. At least part of the positioning columns 3 and the edge of the window 131 are reserved with space so that the product can be supported on the material plate 13 through the space. The support plate 22 is driven to descend, passes through the window 131 and then retracts between the bottom plate 11 and the material plate 13. At this time, the material plate 13 can move along the slide rail 12, so that the window 131 and the support plate 22 are misaligned in the horizontal direction. In actual production, the layering devices for thin products described in this embodiment are generally distributed in multiple sets, and the multiple sets of devices share one robot to complete the suction and transfer of the top layer products. Therefore, when the products on one set of layering devices have been taken away by the robot, and the other layering devices are still in operation, if the operator enters the working area to load the former device, he or she may be easily injured by the robot or the latter running device, which poses a great safety risk. Therefore, in this embodiment, the base frame 1 is configured as a combined structure formed by a base plate 11, a slide rail 12 and a material plate 13. When loading is required, the support plate 22 is controlled to retract between the base plate 11 and the material plate 13, and then the material plate 13 is pulled out horizontally for loading. The loaded product is supported on the material plate 13 through the space reserved between the positioning column 3 and the window 131. After loading is completed, the material plate 13 is pushed back to its original position, so that the positioning column 3 switches to the working state again, and then the support plate 22 is controlled to rise. After the support plate 22 passes over the window 131, it supports the product so that the product is separated from the material plate 13 and supported on the support plate 22 to rise synchronously, and finally cooperates with the high-position sensor 41 to rise to the target height.

It should be noted that the above is only a specific improvement scheme adopted in this embodiment, which is mainly aimed at manual loading and can eliminate the safety risks of manual loading. In other embodiments, the base frame 1 can also adopt an integrated structure, that is, the bottom plate 11, the slide rail 12 and the material plate 13 are all relatively fixed, and are used in occasions such as automatic loading where there is no need to consider the loading risk.

Specifically, the high position sensor 41 is fixed on the bottom plate 11, and the fixing part of the horizontal driving member 51 and the fixing part of the material shifting driving member 61 are both fixed on the material plate 13. In other embodiments, the high position sensor 41 can also be fixed on the material plate 13, and the fixing part of the horizontal driving member 51 and the fixing part of the material shifting driving member 61 can also be fixed on the bottom plate 11.

More specifically, two sets of support components are provided on the base frame 1, and each set of support components is correspondingly provided with a positioning column 3, a high-position detection mechanism 4, a clamping mechanism 5 and a material-dispensing mechanism 6, and the two sets of clamping mechanisms 5 and the two sets of material-dispensing mechanisms 6 are both located between the two sets of positioning columns 3. The two sets of clamping mechanisms 5 and the material-dispensing structures can be distributed along the vertical direction of the two sets of positioning columns 3, occupying less space and having a more reasonable arrangement. In other embodiments, the support components and the corresponding positioning columns 3, high-position detection mechanisms 4, clamping mechanisms 5 and material-dispensing mechanisms 6 can also be provided as a single set or three sets; the clamping mechanisms 5 and the material-dispensing mechanisms 6 can also be uniformly located on the right or left side of the corresponding positioning columns 3.

Furthermore, a positioning piece 14 is provided at one end of the material plate 13, and a push-pull portion 132 is provided at the other end. A matching piece 15 is provided on the bottom plate 11 corresponding to the positioning piece 14. The positioning piece 14 cooperates with the matching piece 15 to achieve relative fixation of the material plate 13 and the bottom plate 11 when the positioning column 3 is in the working state. The positioning piece 14 and the matching piece 15 are provided to ensure the position accuracy of the material plate 13, thereby ensuring the relative position accuracy of each component during operation, and further ensuring the operation accuracy.

Specifically, the positioning member 14 is a positioning block with a positioning hole, and the matching member 15 is a telescopic driving member, and the telescopic shaft of the telescopic driving member is inserted into the positioning hole to achieve matching. The telescopic driving member can be automatically positioned by matching the positioning hole, and the operation is more convenient. In other embodiments, the positioning member 14 and the matching member 15 can also be designed as a matching buckle structure or a magnetic structure.

More specifically, the telescopic driving member is a telescopic cylinder.

In addition, referring to Figures 1 and 2, the layering device of this embodiment is further provided with a blowing mechanism 7, which is mounted on the base frame 1 and includes a blowing nozzle 71, which is suitable for blowing air below the top layer product when the product rises to the target height. The blowing mechanism 7 is a commonly used product layering method in the art, and is used in conjunction with the layering device of this embodiment to blow air between the top layer product and the adjacent lower layer product after the top layer product is separated by the material stripping teeth 62, so as to avoid the two layers of products being re-sucked after separation due to excessive suction between them, thereby further reducing the lamination rate.

Specifically, the air blowing nozzle 71 is fixed to the base frame 1 through the air blowing bracket 72 , that is, the bottom of the air blowing bracket 72 is fixed to the base frame 1 , and the air blowing nozzle 71 is fixed to the top of the air blowing bracket 72 .

The working process of the thin product layering device of this embodiment is as follows:

1) The lifting drive member 21 controls the support plate 22 to retract between the bottom plate 11 and the material plate 13, and the material plate 13 is manually pulled out for loading. The loaded products are stacked on the material plate 13 under the limiting action of the positioning column 3;

2) Manually push the sheet 13 back so that the window 131 on the sheet 13 is vertically aligned with the support plate 22;

3) The photoelectric sensor 23 detects the presence of products above the support plate 22 and controls the lifting drive 21 to start;

4) The lifting drive 21 controls the support plate 22 to rise, and after passing through the window 131, the product is supported and separated from the material plate 13 and supported on the support plate 22 to rise synchronously;

5) The high-level sensor 41 detects the product signal and controls the lifting drive 21 to stop moving. At this time, the top product rises to the target height;

6) The horizontal driving member 51 is started to control the damping block 52 to approach the product until the product is pushed to the opposite side positioning column 3 to fix the product;

7) The horizontal telescopic driving member 611 is started to control the horizontal movement of the material-pickup teeth 62 until the material-pickup teeth 62 touch the side wall of the top layer of products. At this time, the horizontal telescopic driving member 611 continues to drive the material-pickup teeth 62 to move toward the product. The material-pickup teeth 62 stop the horizontal movement under the obstruction of the top layer of products and switch to the rotational movement around the hinge seat 612, thereby driving the separation of the top layer of products from the adjacent lower layer of products;

8) After the top product is separated, the horizontal telescopic drive member 611 retracts in the opposite direction;

9) The blowing mechanism 7 starts to blow air between the top layer product and the adjacent lower layer product;

10) The robot absorbs and removes the top layer of product.

It should be noted that the device can control the manipulator to absorb and remove the top product while the material-pickling teeth 62 lift and remove the top product; it can also make the top product fall back before the manipulator absorbs and removes the top product. Since the stacking of two adjacent layers of products is generally caused by the negative pressure formed between the products, the negative pressure between the products has been destroyed after the material-pickling teeth 62 lift the top product. Even if the top product falls back, it is difficult to form the negative pressure between the products again in a short time before the manipulator absorbs it, so the falling of the product will not cause stacking again. In actual production, the latter is preferably used, because the material-pickling teeth 62 lift the product and put the product in an inclined state, which is easy to destroy the vacuum degree of the manipulator's absorption and affect the normal absorption of the manipulator. Therefore, the top product is generally made to fall back before the manipulator absorbs it, and the blowing mechanism 7 is used to further reduce the stacking rate.
