Description

Technical Field

[0001] This utility model belongs to the technical field of PCB depaneling machines and their accessories, and in particular relates to a tool positioning mechanism for PCB depaneling machines. Background Technology

[0002] PCB depaneling machines are among the most common machines used in circuit board production at present. They are used to separate circuit boards. A PCB depaneling machine mainly consists of three parts: a machine base, a conveyor belt, and a depaneling mechanism. Some PCB depaneling machines are also equipped with dust removal devices. The depaneling mechanism is further divided into a rotating rod, a knife holder, a depaneling knife, and a motor. The rotating rod is used to install the knife holder, and the other end is also connected to the motor. The knife holder is used to install the depaneling knife.

[0003] Chinese patent application CN222981764U discloses a PCB board depaneling machine, primarily addressing the problem that the different positions of the dividing lines on large boards of different sizes necessitate the use of different cutting tools during depaneling. The disassembly and reassembly of these different tools negatively impacts depaneling efficiency. The proposed solution includes: a platform and a machine cover mounted on top of the platform; a moving mechanism that places and moves the board material, with breakpoints on the board surface; a replaceable placement mold mounted on the moving mechanism, with placement slots on the mold into which the board material is placed; and two sets of vertically arranged depaneling mechanisms mounted within the machine cover, each including multiple sets of equidistantly spaced blades. This invention can depanel PCB boards of different sizes, improving applicability, eliminating the need for tool changes, and increasing work efficiency.

[0004] The aforementioned PCB depaneling machine has a depaneling mechanism suspended on the inner top wall of its casing. This mechanism includes a moving frame with multiple mounting blocks evenly spaced at the bottom. Blades are mounted on the bottom of each mounting block. However, the suspended structure presents challenges for blade replacement due to limited working space and difficulty in disassembly and assembly. Furthermore, the blades, which are triangular blocks with exposed blade edges that directly contact the circuit board, pose significant operational risks. Therefore, we provide a blade positioning mechanism for the depaneling machine to address these issues. Utility Model Content

[0008] The present invention is further configured such that the positioning seat, the slide groove and the separating blade are all T-shaped, an electromagnetic post is embedded in the upper side wall of the horizontal end of the slide groove, and a top hole is opened on the bottom side wall of the horizontal end of the separating blade corresponding to the electromagnetic post.

[0009] The present invention is further configured such that a metal block is slidably disposed inside the top hole, and a spring is installed on the upper side wall of the metal block, and the metal block is connected to the inner wall of the top hole through the spring.

[0010] The present invention is further configured such that a side groove is provided at one end of the slide groove, the baffle is disposed in the side groove, and a rotating shaft and a rod are inserted into both ends of the baffle. One end of the baffle is rotatably connected to the side groove through the rotating shaft, and the other end is fixedly connected to the positioning seat through the rod.

[0011] The present invention is further configured such that a groove is provided on one side of the outer wall of the separating blade, and a protrusion is provided on the opposite side of the groove, and the protrusion on one separating blade is inserted into the groove on the adjacent separating blade.

[0012] The present invention is further configured such that a fixing groove is provided at both the left and right ends of the bottom of the positioning seat, and a rotating groove is provided below the fixing groove. A shaft hole is also provided on the rotating groove. The driving component includes a frame fixedly installed in the fixing groove and a vertical plate rotatably installed in the rotating groove.

[0013] The present invention is further configured such that the upright plate is fixedly installed at the end of the upper side wall of the protective plate, and a shaft hole is provided in the rotating groove, and the protective plate is connected to the upright plate through a connecting rod.

[0014] The present invention is further configured such that a rotating rod is provided at the end of the connecting rod, and a gear one is sleeved on the rotating rod; a micro motor is installed in the frame, and a gear two is installed on the shaft of the micro motor; the gear one and the gear two are meshed together.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a positioning seat and a separating blade. The positioning seat has a sliding groove, through which the separating blade is slidably inserted. The positioning seat, sliding groove, and separating blade are all T-shaped. A baffle is rotatably mounted on the outer end of the sliding groove. A groove is formed on one side of the outer wall of the separating blade, and a protrusion is formed on the opposite side. Multiple separating blades are provided. The protrusion on one separating blade is inserted into the groove on another adjacent separating blade, thereby realizing the assembly and combination of multiple separating blades. A spring and a metal block are embedded in the bottom side wall of the horizontal end of the separating blade. An electromagnetic post is embedded in the upper side wall of the horizontal end of the sliding groove of the positioning seat. In use, the rod on one side of the baffle is pulled out, and the baffle is pushed to rotate it, exposing the groove opening of the sliding groove on the positioning seat. The separating blade is then inserted from one side of the groove. This process is repeated to insert other separating blades into the sliding groove in sequence. At this time, the groove on the front separating blade is blocked by the groove on the rear separating blade. The protrusions are inserted sequentially to connect the splitting blades. After the splitting blades are connected, the baffle is rotated in the opposite direction and closed into the side groove. Then, the insert rod is inserted into the baffle from above the positioning seat to fix the baffle and ensure the stability of the splitting blades installed in the baffle. Then, the power supply structure works for the electromagnetic column. At this time, the electromagnetic column generates a large magnetic attraction due to being powered. Since the electromagnetic column is set up vertically opposite to the metal block, it will generate a large attraction force on the metal block. At this time, the metal block pulls the spring to extend until the metal block is attracted to the electromagnetic column. At the same time, the metal block does not detach from the top hole on the splitting blade, thus achieving the effect of stably fixing the splitting blade in the positioning seat. When disassembling the splitting blade, simply cut off the power supply to the electromagnetic column and pull out the insert rod on one side of the baffle to push the splitting blade out of the positioning seat from the side. The splitting blade can also be pulled out from the top.

[0017] 2. This utility model incorporates protective components. Two protective components are located at the bottom of the positioning seat and are positioned opposite each other. Each protective component includes a protective plate rotatably connected to the bottom side wall of the positioning seat. A rubber sleeve is fitted onto the outer wall of the protective plate. The protective plate contacts the cutting edge side wall of the separating blade through the rubber sleeve, thus protecting the cutting edge of the separating blade. Simultaneously, driving components are located at both ends of the upper side wall of the protective plate. Each driving component includes a micro motor embedded in the outer side wall of the positioning seat, with a gear mounted on the shaft of the micro motor. The protective plate is rotatably connected to the positioning seat via a connecting rod. A rotating rod is located at the end of the connecting rod. The device is equipped with gear one, which meshes with gear two. In use, when the slitting blade is not working, the micro motor works, driving gear two on the shaft end to rotate. When gear two rotates, since it is still meshing with gear one, gear one also rotates. When gear one rotates, it drives the rotating rod and connecting rod to rotate. Since the connecting rod is fixed to the end of the protective plate, the protective plate also rotates. The two protective plates move and their ends close together, thus forming a shielding and protective effect on the slitting blade's cutting edge. When the slitting blade is working and needs to cut the circuit board, the micro motor works and reverses, which drives the two protective plates to rotate in the opposite direction, exposing the slitting blade.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Please see Figure 1-3 This utility model is a tool positioning mechanism for a PCB depaneling machine, including a positioning seat 1 and a baffle 2. The baffle 2 can be used to open and close the side groove 101 of the positioning seat 1, and the electromagnetic column 102 can be used to adsorb and fix the depaneling tool 3.

[0029] Specifically, the positioning seat 1 has a sliding groove 101, and the positioning seat 1 is connected to the splitting blade 3 through the sliding groove 101. One end of the sliding groove 101 also has a side groove 103, and a baffle 2 is provided in the side groove 103.

[0030] Furthermore, a rotating shaft 201 and a rod 202 are respectively inserted into both ends of the baffle 2. The baffle 2 is rotatably connected to the side groove 103 through the rotating shaft 201, and the other end is fixedly connected to the positioning seat 1 through the rod 202.

[0031] Example 2

[0032] Please see Figure 3-4 Based on embodiment 1, a splitting blade 3 is also provided, which can achieve the splicing effect between multiple splitting blades 3 through the protrusion 301 and the groove 302.

[0033] Specifically, the positioning seat 1, the slide groove 101 and the dividing blade 3 are all T-shaped. There are multiple dividing blades 3 in the slide groove 101, and adjacent dividing blades 3 are connected end to end. A protrusion 301 is provided on one outer wall of the dividing blade 3, and a groove 302 is provided on the other opposite side. The protrusion 301 on one dividing blade 3 is connected to the groove 302 on the adjacent dividing blade 3.

[0034] Furthermore, an electromagnetic post 102 is embedded in the upper side wall of the horizontal end of the slide 101, and a top hole 303 is opened on the bottom side wall of the horizontal end of the splitting blade 3. A spring 304a is installed in the top hole 303, and a metal block 304 is also inserted into the top hole 303. The upper side wall of the metal block 304 is connected to the top hole 303 through the spring 304a. The metal block 304 is also arranged vertically opposite to the electromagnetic post 102.

[0035] The operation process of this embodiment is as follows: During use, pull out the insert rod 202 on one side of the baffle 2, push the baffle 2 to rotate it, exposing the groove 101 on the positioning seat 1. Then insert the splitting blade 3 from one side of this groove. Repeat this process to insert other splitting blades 3 into the groove 101. At this time, the groove 302 on the front splitting blade 3 is engaged by the protrusion 301 on the rear splitting blade 3, thus sequentially connecting the splitting blades 3. After completing the insertion of the splitting blades 3, rotate the baffle 2 in the opposite direction and close it into the side groove 103. Then insert the insert rod 202 from above the positioning seat 1 into the baffle 2 to fix the baffle 2 and ensure the stability of the splitting blades 3 installed in the baffle 2. Then... The power supply structure is operated by the electromagnetic column 102. When the electromagnetic column 102 is powered, it will generate a large magnetic attraction force. Since the electromagnetic column 102 is set up vertically opposite to the metal block 304, the electromagnetic column 102 will generate a large attraction force on the metal block 304. At this time, the metal block 304 will pull the spring 304a to extend until the metal block 304 is attracted to the electromagnetic column 102. At the same time, the metal block 304 does not detach from the top hole 303 on the splitting blade 3, thereby achieving the effect of stably fixing the splitting blade 3 into the positioning seat 1. When disassembling and assembling the splitting blade 3, it is only necessary to cut off the power supply to the electromagnetic column 102 and pull out the plug 202 on one side of the baffle 2 to push the splitting blade 3 out of the positioning seat 1 from the side. At the same time, the splitting blade 3 can also be pulled out from the top.

[0036] Example 3

[0037] Please see Figure 3 and Figure 5 Based on Embodiments 1 and 2, a protective component 4 is also provided. The protective plate 401 can be rotated by the driving component 403 to achieve the effect of shielding or opening the cutting edge of the splitting blade 3.

[0038] Specifically, the positioning seat 1 has a fixing groove 104 at both the left and right ends of the bottom, and a rotating groove 105 is provided below the fixing groove 104. The rotating groove 105 also has a shaft hole 105a, and a protective component 4 is rotatably installed in the rotating groove 105.

[0039] Furthermore, the protective component 4 includes a protective plate 401 rotatably disposed within the rotating groove 105, and a rubber sleeve 402 is fitted onto the protective plate 401. Upright plates 401a are fixedly disposed on the upper sidewalls at both ends of the protective plate 401, and the upright plates 401a are connected to the positioning seat 1 via a driving component 403. The driving component 403 includes a connecting rod 403a rotatably connected in the shaft hole 105a, and the connecting rod 403a is also fixedly connected to the protective plate 401. A rotating rod 403b is also disposed on the outer side of the protective plate 401 and at the end of the connecting rod 403a, and a gear 403c is fitted onto the rotating rod 403b. A frame 403d is installed in the fixing groove 104, and the fixing groove 104 is connected to the micro motor 403e via the frame 403d. A gear 403f is installed on the shaft of the micro motor 403e, and the gear 403f meshes with the gear 403c.

[0040] The operation process of this embodiment is as follows: When the depaneling blade 3 is not working, the micro motor 403e works, which drives the gear 403f on the shaft end to rotate. When the gear 403f rotates, it is also meshed with the gear 403c, so the gear 403c also rotates. When the gear 403c rotates, it can drive the rotating rod 403b and the connecting rod 403a to rotate. Since the connecting rod 403a is fixed to the end of the protective plate 401, the protective plate 401 also rotates. The two protective plates 401 move and their ends close together, thereby forming a shielding and protective effect on the cutting edge of the depaneling blade 3. When the depaneling blade 3 is working, that is, when the circuit board needs to be cut, the micro motor 403e works and reverses, which can drive the two protective plates 401 to rotate in the opposite direction, exposing the depaneling blade 3.
