Description

Technical Field

[0001] The present application relates to the technical field of sheet material feeding equipment, and in particular to a compact sheet material feeder. Background Art

[0002] In industrial automation production, sheet materials are required for placement. Sheets include, but are not limited to, components like labels. To facilitate transportation and prevent dust from contaminating the adhesive surface of the sheet, the sheet is typically attached to a backing paper. During the sheet feeding process, the backing paper must be peeled off.

[0003] Currently, a clamping jaw is commonly used to clamp the backing paper to separate the sheet material and the backing paper. During the peeling process, not only the clamping jaw needs to move, but the material receiving platform also needs to avoid the clamping jaw. The traditional peeling method requires the separate control of the clamping jaw, the material receiving platform and other structures to move, resulting in a more complicated control process and the need to add corresponding drive equipment, making the overall structure more complex and bulky.

[0004] Therefore, it is necessary to provide a sheet feeder with simpler control and more compact structure. Summary of the Invention

[0005] Based on this, it is necessary to provide a compact sheet feeder, and its specific technical solution is as follows.

[0006] A compact sheet feeder comprising:

[0007] Stripping plate, used to place sheet materials;

[0008] The material receiving assembly includes a material receiving seat, a material receiving platform, and a first elastic member; the material receiving seat is located at the end of the stripping plate; the material receiving platform is slidably mounted on the material receiving seat; the first elastic member has elastic potential energy that drives the material receiving platform to move toward the stripping plate;

[0009] The feeding assembly is used to drive the sheet material on the stripping plate to move toward the receiving platform; the moving direction of the sheet material is a first direction;

[0010] The clamping jaw assembly includes a clamping jaw body and a driving mechanism; the clamping jaw body is located between the stripping plate and the material receiving platform; the driving mechanism is connected to the clamping jaw body and is used to drive the clamping jaw body to reciprocate in a second direction, which intersects with the first direction; when the clamping jaw body moves in the positive direction, it pushes the material receiving platform to move in a direction away from the stripping plate.

[0011] Furthermore, it also includes a pressing plate, which is movably installed on the stripping plate along the second direction; the pressing plate includes a pressing part and a pushing part; the pressing part is located above the stripping plate and is used to press the sheet material onto the stripping plate; the pushing part extends outward toward the end of the stripping plate and is located above the clamping jaw body, so that the pressing plate is lifted when the clamping jaw body moves along the positive direction.

[0012] Furthermore, a second elastic member is connected between the pressing plate and the stripping plate; the second elastic member has elastic potential energy that drives the pressing plate to move toward the stripping plate.

[0013] Furthermore, the clamp body includes a fixed seat, a clamp body and a clamp driving member; a first clamping end is provided on the fixed seat; a second clamping end is provided on the top of the clamp body, and the clamp body is movably installed on the fixed seat along the second direction; the clamp driving member is connected to the clamp body and is used to drive the clamp body to move along the second direction.

[0014] Furthermore, a first pushing portion is provided on the clamping jaw body; the first pushing portion is located below the second clamping end; the material receiving platform is connected to a second pushing portion, and the second pushing portion is located below the material receiving platform; so that when the clamping jaw body moves in the positive direction, the first pushing portion pushes the second pushing portion to move, thereby causing the material receiving platform to move in a direction away from the stripping plate.

[0015] Furthermore, the first pushing portion includes a guiding inclined surface and a transition plane; the transition plane is located below the guiding inclined surface, and the transition plane extends along the second direction.

[0016] Furthermore, the second pushing portion is a cam follower.

[0017] Furthermore, the feeding assembly includes a feeding drive and a pushing plate; the feeding drive is connected to the pushing plate and is used to drive the pushing plate to move in a first direction; the pushing plate includes a tail plate and a rocker plate; the tail plate is located above the stripping plate, and the bottom surface height of the tail plate is lower than the top surface height of the sheet; the rocker plate is connected to the tail plate and extends obliquely upward toward the sheet.

[0018] Furthermore, guide blocks are respectively installed on both sides of the stripping plate; the guide block includes a first guide surface, which is against the edge of the sheet; the guide block is also provided with a limiting protrusion protruding outward from the first guide surface; the limiting protrusion is provided with a limiting inclined surface, and the end of the limiting inclined surface away from the pressing plate is higher than the end close to the pressing plate.

[0019] Furthermore, the first direction is perpendicular to the second direction.

[0020] Beneficial effects: 1. The compact sheet feeder provided by the present invention enables the clamping claw body to move in the positive direction to clamp the base paper, and pushes the feeding platform to automatically avoid it. When it moves in the opposite direction to peel off the base paper, the feeding platform automatically resets and receives the sheet after the base paper is peeled off. The entire process only requires the control of the feeding assembly and the clamping claw assembly. The control method is simpler, thereby saving a large amount of drive structure, making the overall structure of the feeder more compact and more suitable for occasions with limited space; the moving direction of the sheet is crossed with the moving direction of the clamping claw body, reducing the occupation of horizontal space, and is more suitable for occasions with limited horizontal space.

[0021] 2. The present invention provides a compact sheet feeder in which the clamping claw body pushes the pressing plate to move before clamping the base paper, thereby facilitating the sheet to enter between the peeling blade plate and the pressing plate. During the process of clamping the base paper, the pressing plate automatically clamps the sheet under the action of the second elastic member, facilitating better peeling of the base paper when the clamping claw body moves. The control process is simple and convenient, and no additional driving device is required, making the overall structure of the feeder more compact and more suitable for occasions with limited space.

[0051] Example

[0052] This embodiment provides a compact sheet feeder, which is mainly used to peel off the backing paper attached to the sheet 7 and transport the sheet 7 behind the glass to the receiving platform 32 for supplying the equipment operation of the next processing stage. Figure 1 As shown, a compact sheet feeder includes a stripper plate 2, a receiving assembly 3, a feed assembly 4, a clamping assembly 5, and a housing 1. The stripper plate 2, feed assembly 4, and clamping assembly 5 are all mounted on the housing 1. It should be noted that the housing 1 includes at least a first plane and a second plane that are perpendicular to each other, with the stripper plate 2 mounted on the first plane and the clamping assembly 5 mounted on the second plane.

[0053] Specifically, refer to Figure 2 As shown, the stripping plate 2 extends along a first direction. In this embodiment, the first direction can be understood as a horizontal direction. The stripping plate 2 is used to hold the sheet material 7. Multiple sheets 7 can be placed end-to-end on the stripping plate 2, or only one sheet material 7 can be placed. The specific design can be based on parameters such as the size of the equipment and the size of the sheet material 7.

[0054] Specifically, refer to Figure 3 and Figure 4 As shown, the material receiving assembly 3 includes a material receiving seat 31, a material receiving platform 32 and a first elastic member 33. The material receiving seat 31 is located at the end of the stripping plate 2. Specifically, the material receiving seat 31 can be connected to the housing 1, or the material receiving seat 31 can be connected to the equipment of the next processing stage. A gap is formed between the material receiving seat 31 and the stripping plate 2, and the gap is used to accommodate the passage of the clamping claw body 51. The material receiving platform 32 is slidably mounted on the material receiving seat 31. Specifically, a slider and a slide rail can be used to cooperate so that the moving direction of the material receiving platform 32 is a first direction. The first elastic member 33 has elastic potential energy that drives the material receiving platform 32 to move toward the stripping plate 2.

[0055] Specifically, the feeding assembly 4 is mounted on the housing 1 and is used to drive the sheet material 7 on the stripping plate 2 to move toward the receiving platform 32. The moving direction of the sheet material 7 is a first direction.

[0056] Specifically, refer to Figure 1 and Figure 5 As shown, the clamping jaw assembly 5 includes a clamping jaw body 51 and a driving mechanism 52. The clamping jaw body 51 is located between the stripping plate 2 and the material receiving platform 32, specifically in the gap formed between the material receiving seat 31 and the stripping plate 2. The driving mechanism 52 is connected to the clamping jaw body 51 and is used to drive the clamping jaw body 51 to move back and forth along the second direction. The second direction can be understood as the vertical direction, that is, the first direction is perpendicular to the second direction. In this embodiment, the driving structure includes a driving motor 521, a driving wheel 522, a transmission wheel and a belt 523. The driving motor 521 drives the driving wheel 522 to rotate, thereby driving the belt 523 to rotate. The clamping jaw body 51 is connected to the belt 523, thereby driving the clamping jaw body 51 to move. The driving mechanism 52 can also specifically adopt a linear motion module, or a cylinder, oil cylinder or other structure. The second direction intersects the first direction; when the clamp body 51 moves in the positive direction, it pushes the receiving platform 32 to move away from the stripping plate 2. At this time, the clamping end of the clamp body 51 can pass through the receiving platform 32 and the stripping plate 2, making it easier for the clamping end to clamp the backing paper; when the clamp body 51 moves in the negative direction, the receiving platform 32 moves toward the stripping plate 2 under the action of the first elastic member 33. At this time, the backing paper is peeled off as the clamp body 51 moves. The receiving platform 32 is close to the stripping plate 2 and can accurately and reliably receive the peeled sheet 7, thereby feeding the subsequent operation. It should be noted that in this embodiment, movement in the positive direction refers to upward movement, while movement in the negative direction refers to downward movement.

[0057] The compact sheet feeder provided in this embodiment enables the clamping claw body 51 to push the feeding platform to automatically avoid when it moves in the positive direction to clamp the base paper; and when it moves in the reverse direction to peel off the base paper, the feeding platform automatically resets and receives the sheet 7 after the base paper is peeled off, so that the entire process only requires the control of the feeding component 4 and the clamping claw component 5, and the control method is simpler, thereby saving a large amount of drive structure, making the overall structure of the feeder more compact and more suitable for occasions with limited space; the moving direction of the sheet 7 is crossed with the moving direction of the clamping claw body 51, reducing the occupation of horizontal space, and more suitable for occasions with limited horizontal space.

[0058] Specifically, refer to Figure 6As shown, the device further includes a pressure plate 6, which is mounted on the stripping plate 2 for movement in the second direction. Specifically, a copper sleeve 21 is provided on the stripping plate 2, and a guide post 61 is provided on the pressure plate 6. The guide post 61 passes through the copper sleeve 21 and is movably connected to the copper sleeve 21, thereby limiting the movement direction of the pressure plate 6. The pressure plate 6 includes a pressing portion 62 and a pushing portion 63. The pressing portion 62 is located above the stripping plate 2 and is used to press the sheet 7 against the stripping plate 2. The pushing portion 63 extends outward from the end of the stripping plate 2 and is located above the clamping jaw body 51, so that the clamping jaw body 51 can push up the pressure plate 6 when it moves in the positive direction. Before clamping the base paper, the clamping claw body 54 pushes the pressing plate 6 to move, making it easier for the sheet material 7 to enter between the stripping plate 2 and the pressing plate 6. During the process of clamping the base paper, the pressing plate 6 automatically clamps the sheet material 7 under the action of the second elastic member 64, making it easier to peel off the base paper when the clamping claw body 54 moves. The control process is simple and convenient, and no additional driving equipment is required, making the overall structure of the feeder more compact and more suitable for occasions with limited space.

[0059] Specifically, a second elastic member 64 is connected between the pressing plate 6 and the stripping plate 2. This second elastic member 64 has elastic potential energy that propels the pressing plate 6 toward the stripping plate 2. When the jaws 54 grip the backing paper, the jaws 54 move downward, allowing the pressing plate 6 to automatically move toward the stripping plate 2 under the action of the second elastic member 64, thereby compressing the sheet 7.

[0060] Specifically, continue to refer to Figure 5 As shown, the clamp body 51 includes a fixed base 53, a clamp body 54, and a clamp driver 55. The fixed base 53 is provided with a first clamping end 531. The top of the clamp body 54 is provided with a second clamping end 541, and the clamp body 54 is movably mounted on the fixed base 53 along a second direction. The clamp driver 55 is connected to the clamp body 54 and is used to drive the clamp body 54 to move in the second direction. The clamp driver 55 can drive the clamp body 54 downward, so that the first clamping end 531 and the second clamping end 541 clamp the backing paper. When the clamp body 54 moves downward, the pressure plate 6 loses its support and, under the action of the second elastic member 64, moves downward to press the sheet 7 against the stripping plate 2.

[0061] Specifically, the clamping jaw 54 is provided with a first pushing portion 542 located below the second clamping end 541. The material receiving platform 32 is connected to a second pushing portion 321 located below the material receiving platform 32. When the clamping jaw 54 moves in the positive direction, the first pushing portion 542 pushes the second pushing portion 321, thereby moving the material receiving platform 32 away from the stripping plate 2. Consequently, when the clamping jaw 54 moves in the positive direction, i.e., upward, under the action of the drive mechanism 52, the first pushing portion 542 pushes the second pushing portion 321, thereby moving the material receiving platform 32 away from the stripping plate 2. This creates a gap between the material receiving platform 32 and the stripping plate 2 to accommodate the passage of the second clamping end 541 of the clamping jaw 54, thereby facilitating the cooperation between the second clamping end 541 and the first clamping end 531 to clamp the backing paper. When the clamping jaw 54 moves in the opposite direction, i.e., moves downward, under the action of the driving mechanism 52, the second pushing portion 321 loses the squeezing of the first pushing portion 542, so that the material receiving platform 32 moves toward the direction close to the stripping plate 2 under the action of the first elastic member 33. When the clamping jaw 54 moves downward and peels off the backing paper, the material receiving platform 32 moves just close to the end of the stripping plate 2, so as to conveniently receive the sheet 7 after the backing paper is peeled off.

[0062] Specifically, the first pusher 542 includes a guide bevel 543 and a transition plane 544; the transition plane 544 is located below the guide bevel 543 and extends along the second direction. In this embodiment, the downward movement of the jaw body 54 occurs in two stages. In the first stage, the jaw body 54, driven by the jaw driver 55, moves downward, causing the second clamping end 541 and the first clamping end 531 to clamp the backing paper. During this process, the second pusher 321 remains in contact with the transition plane 544, and the receiving platform 32 does not move. In the second stage, the jaw body 54, driven by the drive mechanism, moves downward as a whole along with the jaw body 51. During this process, the second pusher 321 transitions from contact with the transition plane 544 to contact with the guide bevel 543, and finally separates from the first pusher 542. The receiving platform 32 gradually moves close to the stripper plate 2 to receive the backing paper.

[0063] Specifically, refer to Figure 4 As shown, the second pushing portion 321 is a cam follower. During the relative movement of the first pushing portion 542 and the second pushing portion 321, rolling contact is maintained, thereby making the relative movement smoother.

[0064] Specifically, refer to Figure 7As shown, the feed assembly 4 includes a feed drive 41 and a push plate 42. The feed drive 41 is connected to the push plate 42 and is used to drive the push plate 42 to move in a first direction. The push plate 42 includes a tail plate 421 and a rocker plate 422. The tail plate 421 is located above the stripper plate 2, and the bottom surface of the tail plate 421 is lower than the top surface of the sheet 7. The rocker plate 422 is connected to the tail plate 421 and extends obliquely upward toward the sheet 7. When the sheet 7 is pushed to move on the stripper plate 2, the rocker plate 422 prevents the tail of the sheet 7 from tilting upward, thereby ensuring that the sheet 7 can be accurately peeled off the backing paper and moved to the receiving platform 32.

[0065] Specifically, guide blocks 22 are respectively installed on both sides of the stripping plate 2; the guide block 22 includes a first guide surface 221, which abuts against the edge of the sheet 7; the guide block 22 is also provided with a limiting protrusion 222 protruding outward along the first guide surface 221; the limiting protrusion 222 is provided with a limiting inclined surface 223, and the end of the limiting inclined surface 223 away from the pressing plate 6 is higher than the end close to the pressing plate 6.

[0066] Specifically, refer to Figure 8 As shown, guide blocks 22 are mounted on either side of the stripping plate 2. The guide blocks 22 include a first guide surface 221 that abuts against the edge of the sheet 7. The guide blocks 22 are also provided with a stopper protrusion 222 that projects outward from the first guide surface 221. The stopper protrusion 222 is provided with a stopper slope 223, with the end of the stopper slope 223 farther from the press plate 6 being higher than the end closer to the press plate 6. The first guide surface 221 limits the lateral displacement of the sheet 7, while the stopper slope 223 guides the leading end of the sheet 7, preventing it from tilting. This allows the sheet 7 to smoothly enter between the press plate 6 and the stripping plate 2, facilitating the subsequent accurate gripping of the backing paper by the clamping jaws 54 and the accurate reception of the sheet 7 after the backing paper has been stripped by the receiving platform 32.

[0067] Working process: The feeding drive member 41 drives the pushing plate 42 to move toward the pressing plate 6, pushing the sheet 7 on the stripping plate 2 toward the pressing plate 6; while the sheet 7 is continuously pushed by the pushing plate 42, the driving mechanism 52 drives the clamping claw body 51 to move upward. At this time, the first pushing part 542 pushes the second pushing part 321 to move, so that the material receiving platform 32 moves in the direction away from the stripping plate 2 to provide a gap for the clamping claw body 54. The clamping claw body 54 continues to move upward to push up the pressing plate 6, so that a gap is formed between the pressing plate 6 and the stripping plate 2 to accommodate the sheet 7. When the sheet 7 enters between the pressing plate 6 and the stripping plate 2, the clamping claw body is driven by the clamping claw driving member 55. 54 moves downward, at this time the second clamping end 541 on the clamping claw body 54 and the first clamping end 531 on the fixing seat 53 clamp the bottom paper, and at the same time the clamping claw body 54 no longer lifts the pressing plate 6, so that the pressing plate 6 presses the sheet 7 onto the stripping plate 2 under the action of the second elastic member 64; the driving mechanism 52 drives the clamping claw body 51 to continue to move downward, so that the clamping claw body 54 clamps the bottom paper and continues to move downward, so that the first pushing part 542 no longer supports the second pushing part 321, and the material receiving platform 32 moves close to the stripping plate 2 under the action of the first elastic member 33. During the continuous downward movement of the clamping claw body 54, the sheet 7 is peeled off from the bottom paper, and the sheet 7 after peeling off the bottom paper moves to the material receiving platform 32.

[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
