Description
Technical Field
[0001] The utility model belongs to the technical field of edge grinding for circuit board production, and particularly relates to an edge grinding machine with high safety performance. Background Technique
[0002] The edge grinding machine has the characteristics of one-time rough grinding, fine grinding, and polishing, and is suitable for grinding the inclined surfaces and straight edges of metal strips with different sizes and thicknesses. It is equipped with grinding wheels and spares. The grinding wheels have the advantages of long service life, regular forming, and high efficiency.
[0003] During the production process of circuit boards, due to burrs on the four sides of the cut substrate, it is necessary to perform edge grinding operations on the four sides of the substrate. That is, the substrate is placed on the conveyor line, and the edge of the substrate is ground by a grinding knife. Subsequently, after the substrate is rotated 90 degrees by a rotating plate component, the edge of the other side of the substrate is ground, and the operations of grinding and rotating the substrate are repeated until the edge grinding of the four sides of the substrate is completed.
[0004] During the existing edge grinding operation process, the edge grinding machine is placed in the production position, and its surrounding area is framed by a yellow warning line to mark the operation area, thereby prompting the operator not to cross the yellow warning line to avoid hurting the operator during the process of the rotating plate component rotating the substrate. However, only relying on the reminder function, it is very difficult to avoid unexpected situations. For example, if a person inadvertently stands within the operation area, the substrate is likely to scratch the person during the rotation process, causing personal injury and greatly reducing the safety of the operation process. Content of the Utility Model
[0005] In order to solve the deficiencies of the existing technology, the utility model provides an edge grinding machine with high safety performance. Through the design of a blocking plate component, a blocking plate shell and a protective groove are provided on one side corresponding to the conveyor component and the rotating plate component. When the substrate is rotated 90 degrees by the rotating plate component, the position of the blocking plate shell is equivalent to separating the personnel from the rotating plate operation range. Even if a person strays into the area framed by the yellow warning line, when the substrate is rotating, it can prevent the person from entering the area where the substrate rotates, thereby avoiding personal injury and effectively improving the safety of the edge grinding operation.
[0006] The technical effects to be achieved by the utility model are realized through the following aspects:

The first surface is connected to the second side, and the area formed by the second surface recessing towards the second side constitutes the adjustment groove; the blocking block moves in the adjustment groove.
[0012] In some implementation manners, the adjustment groove includes a groove cavity and a groove opening. The groove opening is arranged on the second surface, and the groove opening penetrates through the second surface and the groove cavity;
[0013] Among them, in a cross-section parallel to the second surface, the cross-sectional dimension of the groove opening is smaller than the cross-sectional dimension of the groove cavity.

One end of the deceleration block is connected to the second side, the other end of the deceleration block is connected to the stop plate block, and the limit block is connected to the other end of the stop plate block relative to the deceleration block.
[0017] In some implementation manners, the deceleration plate includes a main body and a deceleration layer. The deceleration layer is arranged on a surface of the main body facing the protective groove;
[0018] Among them, the thickness of the deceleration layer gradually increases towards the direction of the stop plate block, and deceleration bumps are arranged in an array on the surface of the deceleration layer.
[0019] In some implementation manners, a buffer layer is arranged on a side of the stop plate block facing the protective groove.
[0020] In some implementation manners, the baffle component further includes a pair of infrared sensors. The pair of infrared sensors are arranged on both sides of the baffle shell, and the rays of the pair of infrared sensors pass through the protective groove.

[0035] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.
[0036] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0037] Embodiment 1:
[0038] Please refer to the attached Figure 1-2 , A grinding machine with high safety performance of the present utility model includes a conveyor component 1, a rotary plate component 2 and a baffle component 3. The conveyor component 1 is provided with a first side 11 and a second side 12 opposite to each other. The rotary plate component 2 is arranged on the first side 11, and the baffle component 3 is arranged on the second side 12 and is arranged opposite to the rotary plate component 2. Among them, the baffle component 3 includes a baffle shell 31 and a protection groove 32. The protection groove 32 is recessed from the baffle shell 31 in a direction away from the rotary plate component 2, and the baffle shell 31 is connected to the second side 12. Preferably, as Figure 3-4 shown, the protection groove 32 is an arc-shaped protection groove 32 or a rectangular protection groove 32 or a sharp-angle protection groove 32. It can be flexibly set according to the actual production situation, which can effectively ensure that the protection groove 32 can hold the diagonal edge of the substrate and prevent the substrate from hitting the baffle shell 31 during rotation, ensuring the normal operation of grinding.
[0039] It can be understood that the conveyor component 1 can be realized by using an existing roller group, which is used to convey the substrate to each working station until the four edges of the substrate are ground, thereby completing the conveying operation.
[0040] The rotating plate component 2 can adopt a bidirectional pushing cylinder and a rotating motor. The bidirectional pushing cylinder is used to clamp the substrate, and the rotating motor is used to rotate the substrate clamped by the cylinder by 90 degrees, so as to switch the edge of the substrate for grinding.
[0041] The blocking plate component 3 is arranged on the second side 12 of the conveying component 1, and is used to separate the rotating plate area during the operation of the rotating plate component 2, so as to avoid scratches caused by personnel accidentally entering the rotating plate area.
[0042] In the edge grinding machine of this embodiment, when the rotating plate component 2 rotates the substrate, the rotating plate component 2 clamps a corner of the substrate. After rotating 90 degrees, the edge of the substrate is switched. During the rotation process, the substrate rotates between the blocking plate housing 31 and the rotating plate component 2. Even if the diagonal edge of the substrate protrudes outside the conveying component 1, it is placed in the protection groove 32, so as to separate the personnel from the substrate rotation area and avoid scratches caused by the rotation of the substrate, which can effectively improve the safety of the edge grinding operation.
[0043] Embodiment 2:
[0044] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the blocking plate component 3 of the present invention.
[0045] Please refer to Figure 5 , the blocking plate housing 31 of this embodiment includes a base block 33 and a blocking block 34. The base block 33 is fixedly connected to the second side 12, and the blocking block 34 is telescopically connected to the base block 33. Among them, the length between the blocking block 34 and the base block 33 can be flexibly shortened or extended according to the size of the substrate, which is suitable for the protection of substrates of various sizes, has a wide application range and high flexibility.
[0046] Specifically, the base block 33 includes a first block body 331 and an adjustment groove 332. The first block body 331 is provided with a first surface 3311 and a second surface 3312 opposite to each other. The first surface 3311 is connected to the second side 12, and the area formed by the second surface 3312 recessed toward the second side 12 forms the adjustment groove 332; the blocking block 34 moves in the adjustment groove 332.
[0047] The blocking block 34 is provided with a movable sub-block 341 embedded in the adjustment groove 332 and a blocking sub-block 342 protruding upward from the movable sub-block 341; among them, a clamping portion 3411 is provided at one end of the movable sub-block 341 away from the blocking sub-block 342 and abuts against the notch 3322. By the abutting setting of the clamping portion 3411 and the notch 3322, it is ensured that the blocking block 34 moves and adjusts smoothly in the adjustment groove 332, and the phenomenon that the blocking block 34 disengages from the adjustment groove 332 is avoided.
[0048] Preferably, please refer to Figure 6, the adjustment slot 332 includes a slot cavity 3321 and a slot opening 3322. The slot opening 3322 is provided on the second surface 3312 and penetrates through the second surface 3312 and the slot cavity 3321. Among them, in a cross-section parallel to the second surface 3312, the cross-sectional dimension of the slot opening 3322 is smaller than that of the slot cavity 3321.
[0049] In this embodiment, the cooperation of the base block 33 and the blocking block 34 is as follows: When the substrate size is large, it is necessary to increase the length between the blocking block 34 and the base block 33, that is, pull the movable block 341 of the blocking block 34 towards the slot opening 3322 until the clamping portion 3411 fits with the slot opening 3322. At this time, the blocking block 34 and the base block 33 are at the maximum length, which is equivalent to increasing the space of the protection slot 32 to accommodate the swivel plate movement of the large-size substrate. Of course, when the substrate size is small, the length between the blocking block 34 and the base block 33 can be shortened, that is, push the movable block 341 of the blocking block 34 into the slot cavity 3321 until the clamping portion 3411 is attached to the innermost end of the slot cavity 3321, which is equivalent to reducing the space of the protection slot 32. Through this setting, this structure is applicable to the edge grinding of substrates of different sizes, with a large application range and high operation flexibility.
[0050] In addition, a handle can be provided at the blocking block 342 to facilitate the pulling of the blocking block 34 in the adjustment slot 332 and improve the operation convenience.
[0051] Embodiment 3:
[0052] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the blocking plate component 3 of the present invention.
[0053] Please refer to Figures 7 to 9 , the blocking plate shell 31 of this embodiment includes a deceleration block 35, a stop plate block 36, and a limit block 37. One end of the deceleration block 35 is connected to the second side 12, the other end of the deceleration block 35 is connected to the stop plate block 36, and the limit block 37 is connected to the other end of the stop plate block 36 relative to the deceleration block 35.
[0054] The design of the blocking plate shell 31 in this embodiment is used for the situation where when the swivel plate component 2 fails and the substrate is not firmly clamped during the swivel plate operation, resulting in the substrate flying out due to inertia.
[0055] Among them, the deceleration block 35 is used to reduce the speed of the substrate after flying out to facilitate quickly stabilizing the inertia of the substrate. The stop plate block 36 is used to intercept the substrate flying out due to inertia into the protection slot 32 to ensure safety. The limit block 37 is used to prevent the substrate from turning up and effectively limit the substrate. Specifically, due to the too fast flying speed of the substrate and being blocked by the stop plate block 36, the other positions of the substrate are prone to turning up actions, and the setting of the limit block 37 is to avoid the occurrence of this phenomenon.
[0056] In the baffle housing 31 of this embodiment, when the substrate flies out during the edge grinding operation, due to inertia, the substrate flies towards the baffle housing 31. First, the substrate is preliminarily decelerated by the deceleration block 35, and then the substrate is restricted by the stop plate 36 so that the substrate stops flying out. Finally, the remaining jitter of the substrate after being controlled is controlled by the limit plate, ensuring that the flying-out substrate is safely and stably controlled, avoiding damage to personnel or objects, improving the preventive performance, and greatly improving the safety of the operation.
[0057] Specifically, the deceleration plate includes a main body 351 and a deceleration layer 352. The deceleration layer 352 is arranged on the side of the main body 351 facing the protection groove 32. Among them, the thickness of the deceleration layer 352 gradually increases in the direction of the stop plate 36. The deceleration bumps 3521 are arranged in an array on the surface of the deceleration layer 352. Among them, the thickness of the deceleration layer 352 gradually increases in the direction of the stop plate 36, that is, the deceleration layer 352 is arranged as an inclined plane. Through this setting, during the contact process between the substrate and the deceleration layer 352, the resistance it receives when flying out can be obtained, and then the flying-out speed can be quickly reduced. In addition, by setting the deceleration bumps 3521, the resistance in the direction opposite to the flying-out direction of the substrate can be further increased, accelerating the reduction of the substrate speed. It effectively realizes the ability to strongly decelerate the substrate, greatly reduces the kinetic energy of the substrate, and then can accelerate the stabilization of the substrate.
[0058] A buffer layer 361 is arranged on the side of the stop plate 36 facing the protection groove 32. Among them, the buffer layer 361 can adopt a flexible buffer layer 361, such as a silica gel buffer layer 361, which can quickly consume the kinetic energy of the substrate and realize the control and limitation of the substrate. And through the setting of the buffer layer 361, the service life of the stop plate 36 can also be extended, effectively reducing the impact force of the substrate on the stop plate 36 and ensuring the durability of the stop plate 36.
[0059] In addition, the baffle component 3 further includes a pair of photoelectric sensors 38. The pair of photoelectric sensors 38 are arranged on both sides of the baffle housing 31, and the rays of the pair of photoelectric sensors 38 pass through the protection groove 32. Through this setting, when the pair of photoelectric sensors 38 sense that the substrate is located in the protection groove 32 for a set period of time, it can be judged that the substrate has flown out or other fault problems, and the signal is transmitted to the system. The system then transmits the action signal of switching and stopping to the edge grinder, causing the edge grinder to stop working, issue an alarm, and conduct an inspection. Through this setting, problems can be discovered in time to ensure the timely solution of faults.
