Description

Technical Field

[0001] The invention belongs to the technical field of PCB pilot test, and in particular relates to a PCB production line and method for pilot test. Background Art

[0002] The pilot test is a test before the product is officially put into production. Its main purpose is to verify whether there will be any problems in each process at each link of the production line. It is an important project to reduce the losses of the enterprise.

[0003] PCB board, also known as printed circuit board, is the support body of electronic components. It needs to go through multiple processes for processing and production at the production end, covering cutting, copper deposition, lamination, exposure, development, electrocopper, electrotin, film stripping, etching, tin stripping and other steps. In general production lines, the plates are transferred to various process links for processing through plate displacement equipment; in the pilot stage, although the plate displacement equipment is the most basic, it is also the most troublesome. If you want to build a completely identical production line, it is very troublesome to dismantle it after its construction and pilot test. Therefore, a plate displacement mechanism that can be easily built and used is needed. On the one hand, it can shorten the construction period of the pilot production line, and on the other hand, it can also achieve the purpose of the pilot test. Summary of the invention

The positioning seat provides support for other parts, and clamps the plate through the cooperation of the "C"-shaped structure, the clamping plate and the fixing spring; more specifically, when the push plate is in the process of moving the clamp, and when clamping and releasing materials are required, it is squeezed and pushed by the pressure plate, and then the locking plate is driven to slide by the pull wire. When the locking plate moves to the end, the locking plate is locked by the plug plate. During this process, the locking plate drives the driving wheel to rotate, and the driving wheel drives the curling wheel to rotate. The curling wheel tightens the lead wire, and then pulls the clamping plate up. At this time, the clamp is in a state of waiting for feeding or discharging, and when the pressing plate leaves the pushing plate, the locking plate is positioned because of the plug plate and cannot be restored; at the same time, in the pin groove, the reset spring gives downward pressure to the inclined slot block through the pushing block, and The pressing plate is ejected from a pop-up window. If it is in the feeding state, the pressing plate and the push plate are separated at this time. When the end of the plate slides between the clamping plate and the positioning seat to the pop-up window, it touches and squeezes the pressing plate, lifts the inclined slot block through the pressing plate, and then lifts the plug plate to release the lock of the lock plate. Under the action of the fixed elastic part, the clamping plate is pressed down and cooperates with the positioning seat to clamp the plate, and at the same time, the push plate is driven to reset through the pull wire; if it is in the discharging state, the pressing plate and the push plate are still in contact at this time, and continue to apply pressure to the push plate, and the clamp is separated from the plate. Although the plate will squeeze the pressing plate during the removal process, due to the cooperation between the pressing plate and the push plate, the clamp is still in an open state and does not affect the release of the plate; therefore, the clamping and releasing state of the plate depends only on the length and position of the pressing plate; in order to better realize the above functions, the pressing plate and the push plate should be squeezed together, and the pressing plate should be made of a material with a certain elasticity, such as rubber, which can be squeezed and fitted with the push plate without affecting the movement of the clamp.

[0007] Furthermore, the translation slide rail includes an upper slide and a lower slide; the upper slide and the lower slide are both "L"-shaped structures, and the upper slide and the lower slide cooperate with each other to form a "C"-shaped structure; there is a gap between the upper slide and the lower slide; a side surface of the lower slide is connected to a partition, the partition is an "L"-shaped structure, a first slot body is formed between the partition and the lower slide, and the opening direction is upward, a driving belt is installed in the first slot body, and several driving belts are arranged end to end in an "I" shape; the rotating disk of the driving belt is installed at one end of the connecting shaft, and the other end of the connecting shaft passes through the partition; the side surface of the partition is connected to a limiting plate, the limiting plate is an "L"-shaped structure, the limiting plate and the partition cooperate with each other to form a second slot body, and the opening direction is downward; a driving disk is installed in the second slot body, and the driving disk is connected to the connecting shaft; a connecting plate is installed on one side surface of the upper slide, and a fixing plate is connected between the connecting plate and the limiting plate, and the fixing plate is a "C"-shaped structure; Among them, the driving belt is connected to the translation wheel; the rotating block slides in the fixed plate; the translation slide rail is used to move the clamp and the plate thereon, and the cooperation of the upper slide plate and the lower slide plate allows the translation wheel and the rotating block to extend out of the range surrounded by the upper slide plate and the lower slide plate; in this process, it is only necessary to move the plate up and down, so the clamp thereon can be driven to slide only by driving the translation wheel.

[0008] Furthermore, the flip slide rail includes a straight entry rail, a turning rail, a straight exit rail and a transmission belt; the structure of the straight entry rail is the same as that of the straight exit rail, the straight entry rail and the straight exit rail are respectively connected to the two ends of the turning rail, and the turning rail is a "human" shaped structure; the transmission belt is connected to one side of the track formed by the straight entry rail and the straight exit rail, and the length of the transmission belt is the same as the total length of the straight entry rail, the turning rail, and the straight exit rail; a connecting plate is also installed in the transmission belt, and the two ends of the connecting plate are respectively connected to the straight entry rail and the straight exit rail; The straight-in rail comprises an upper straight rail and a lower straight rail, both of which are "L"-shaped structures, and the upper straight rail and the lower straight rail cooperate with each other to form a "C"-shaped structure, and there is a gap between the upper straight rail and the lower straight rail, and the upper straight rail and the lower straight rail are connected by a frame; a side plate is provided on one side of the lower straight rail, and a transmission belt is installed on one side of the side plate, and the transmission belt is engaged with the rotating block; the function of the flip rail is to flip the clamp and the plate clamped therein, and the flip rail only needs to be connected between the two translation rails before the process that needs to be flipped The plate can be flipped by turning the slide rail; when the fixture moves to the flipping slide rail, the fixture is driven only by the rotating block. When entering the turning rail from the straight entry rail, the translation wheel at the forward end of the fixture sinks first. As the fixture continues to move and the other translation wheel gradually separates from the straight entry rail, the translation wheel at the forward end slides into the turning rail. Since the turning rail is a "human" shaped structure, when the translation wheel at the forward end enters the lowest point of the turning rail, the other translation wheel is at the highest point and completes the flipping under the continued advancement of the rotating block, and enters the straight exit rail to complete the flipping operation of the plate.

[0009] Furthermore, the sides of the lower straight rail and the lower slide plate are both provided with slide grooves, and the positions of the slide grooves are adapted to the push grooves.

[0010] Furthermore, the translation wheel and the rotating block are both connected to the positioning seat via an axle, and the axle of the rotating block is longer than that of the translation wheel, and the rotating block and the translation wheel are rotationally connected to the connected axle.

[0011] Furthermore, pressing plates are provided in the slideways at the feeding position and the discharging position of the PCB board production line.

[0012] Furthermore, the shortest distance from the connecting plate to the lower straight rail is greater than the farthest distance from the translation wheel to the lower straight rail.

[0013] A production method for a pilot PCB production line comprises the following steps: Step 1: Determine the production process of the PCB board and determine the location of all machines except the board cutting process; Step 2: According to the production process, several translation slide rails are spliced ​​and run through various processing machines; and the flip slide rails are inserted into the front station of the process where the plate needs to be flipped; Step 3: Slide the cut plate into the initial position and fix it with a clamp, start the drive belt on the translation slide rail, slide the plate fixed by the clamp into the next station for processing, and conduct a pilot test of the PCB board production line. Record and file it after completion.

[0014] The present invention has the following beneficial effects: The present invention fixes the plate by a clamp, which is convenient for transportation in the subsequent pilot process and improves the pilot efficiency; the plate is transported to each process position for processing by setting a translation slide rail, and the automatic flipping of the plate can be achieved by inserting a flipping slide rail between two translation slide rails in front of the processing position where the plate needs to be flipped for processing; The present invention modularizes the plate displacement equipment and connects and builds the processing equipment with the translation slide rail and the flip slide rail according to the process requirements during the actual pilot test, so as to quickly complete the production line of the PCB board for the pilot test, improve the construction efficiency and reduce the pilot test cycle.

The driving wheel 106 is meshed with the winding wheel 107, and a winding cylinder is provided on the side of the winding wheel 107. The outer peripheral side of the winding cylinder passes through the lead hole 117 in sequence through the lead wire, and is connected to the clamping plate 102 after the window is opened. The lock plate 104 is installed in the lock slot 115, and the lock plate 104 and the lock slot 115 are slidably matched; a rack is provided on the upper surface of the lock plate 104, and the rack is meshed with the driving wheel 106; a pin slot 116 is provided at one end of the lock slot 115 away from the lead hole 117; The pin slot 116 is provided with a cover plate 118, a reset spring 108, a push block 109, a chute block 110, a pressing plate 111 and a plug plate 112; one surface of the cover plate 118 is connected in sequence by the reset spring 108, the push block 109, the chute block 110, and the plug plate 112, and the pressing plate 111 is arranged on the side of the chute block 110; a pop-up window is provided on the side wall of the pin slot 116, and the position of the pop-up window is on the same side as the clamping plate 102 and is located on the clamping plate 102. A side away from the fixed elastic member 103; the pressing plate 111 is installed in the pop-up window, and the pressing plate 111 is elastically connected to the pop-up window, and a protrusion is also provided on the surface of the pressing plate 111 exposed from the pop-up window; the surface of the pressing plate 111 opposite to the protrusion is a wedge-shaped structure; a wedge-shaped groove is provided on the side of the inclined groove block 110, and the wedge-shaped groove and the wedge-shaped structure of the pressing plate 111 are fitted together; a slot is provided on the side of the lock plate 104 close to the pin slot 116, and the plug plate 112 is plugged into the slot; A push plate 105 is installed in the push groove, and the communication position between the push groove and the lock groove 115 is located between the lead hole 117 and the pin groove 116. One end of the push plate 105 is connected to the lock plate 104 through a pull wire, and a push ball is arranged at the end of the push plate 105 away from the pull wire; a shield plate 119 is covered on the side of the push groove away from the push ball, and the push plate 105 slides in the push groove; A translation wheel 113 and a rotating block 114 are also provided on the side of the positioning seat 101 where the push groove is opened. The rotating block 114 is located in the middle position of the positioning seat 101, and the positions of the two translation wheels 113 are symmetrical about the rotating block 114; pressure plates are provided in the slide grooves at the feeding position and the discharging position of the PCB board production line.

[0023] The translation wheel 113 and the rotating block 114 are both connected to the positioning seat 101 through an axle, and the axle of the rotating block 114 is longer than that of the translation wheel 113. The rotating block 114 and the translation wheel 113 are rotationally connected to the connected axle.

[0024] It should be noted that the function of the clamp 1 is to clamp the plate 4 to be processed to facilitate the subsequent process. The positioning seat 101 provides support for other parts, and the plate 4 is clamped by the cooperation of the "C"-shaped structure, the clamping plate 102 and the fixing spring 103; more specifically, when the push plate 105 is in the process of moving the clamp 1, and when clamping and releasing materials are required, it is squeezed and pushed by the pressure plate, and then the locking plate 104 is driven to slide through the pull wire. When the locking plate 104 moves to the end, the locking plate 104 is locked by the plug plate 112. In this process, The locking plate 104 drives the driving wheel 106 to rotate, and the driving wheel 106 drives the curling wheel 107 to rotate. The curling wheel 107 tightens the lead wire, thereby pulling the clamping plate 102 up. At this time, the clamp 1 is in a state of waiting for feeding or unloading, and when the pressing plate leaves the pushing plate 105, the locking plate 104 is positioned and cannot be restored because of the inserting plate 112; at the same time, in the pin groove 116, the reset spring 108 gives downward pressure to the inclined slot block 110 through the pushing block 109, and the pressing plate 111 is ejected. If it is in the feeding state, the pressing plate and The push plate 105 is separated, and when the end of the plate 4 slides between the clamping plate 102 and the positioning seat 101 to the pop-up window, it touches and squeezes the pressing plate 111, and the inclined slot block 110 is lifted by the pressing plate 111, and then the plug plate 112 is lifted to release the lock of the locking plate 104. Under the action of the fixed elastic member 103, the clamping plate 102 is pressed down to cooperate with the positioning seat 101 to clamp the plate 4, and the push plate 105 is reset by the pull wire; if it is in the discharging state, the pressing plate and the push plate 105 are still in contact at this time, and continue to apply pressure to the push plate 105, clamping Plate 102 is separated from plate 4. Although plate 4 will squeeze pressing plate 111 during the removal process, due to the cooperation between the pressing plate and the push plate 105, the clamp 1 is still in an open state and does not affect the release of plate 4. Therefore, the clamping and release state of plate 4 by the clamp 1 only depends on the length and position of the pressing plate. In order to better realize the above functions, the pressing plate and the push plate 105 should be extruded and matched, and the pressing plate should be made of a material with a certain elasticity, such as rubber, which can be extruded and fit with the push plate 105 without affecting the movement of the clamp 1.

[0025] like Figure 1 , Figure 2 , Fig.12 , Fig.13The translation slide rail 2 shown includes an upper slide plate 201 and a lower slide plate 202; the upper slide plate 201 and the lower slide plate 202 are both "L"-shaped structures, and the upper slide plate 201 and the lower slide plate 202 cooperate with each other to form a "C"-shaped structure; there is a gap between the upper slide plate 201 and the lower slide plate 202; a side of the lower slide plate 202 is connected to a partition plate 204, the partition plate 204 is an "L"-shaped structure, and a first groove body is formed between the partition plate 204 and the lower slide plate 202, and the opening direction is upward, and a driving belt 203 is installed in the first groove body, and a plurality of driving belts 203 are arranged head to tail in a "one" shape; the driving belt 203 is ... The rotating disk with 203 is installed at one end of the connecting shaft 207, and the other end of the connecting shaft 207 passes through the partition 204; the side of the partition 204 is connected to the limiting plate 205, and the limiting plate 205 is an "L"-shaped structure. The limiting plate 205 and the partition 204 cooperate with each other to form a second groove body, and the opening direction is downward; a driving disk 208 is installed in the second groove body, and the driving disk 208 is connected to the connecting shaft 207; a connecting plate 209 is installed on one side of the upper slide plate 201, and a fixing plate 206 is connected between the connecting plate 209 and the limiting plate 205, and the fixing plate 206 is a "C"-shaped structure; The driving belt 203 is connected to the translation wheel 113; the rotating block 114 slides in the fixed plate 206; Among them, the sides of the lower straight rail and the lower slide plate 202 are both provided with sliding grooves, and the positions of the sliding grooves are adapted to the push grooves.

[0026] It should be noted that the translation slide rail 2 is used to move the clamp 1 and the plate 4 thereon, and the cooperation between the upper slide 201 and the lower slide 202 allows the translation wheel 113 and the rotating block 114 to extend out of the range surrounded by the upper slide 201 and the lower slide 202; in this process, it is only necessary to move the plate 4 up and down, so the clamp 1 thereon can be driven to slide only by driving the translation wheel 113.

[0027] like Fig.14 , Fig.15 As shown, the flip slide includes a straight entry rail 301, a turning rail 302, a straight exit rail 303 and a transmission belt 304; the structure of the straight entry rail 301 is the same as that of the straight exit rail 303, the straight entry rail 301 and the straight exit rail 303 are respectively connected to the two ends of the turning rail 302, and the turning rail 302 is a "human" shaped structure; the transmission belt 304 is connected to one side of the track formed by the straight entry rail 301 and the straight exit rail 303, and the length of the transmission belt 304 is the same as the total length of the straight entry rail 301, the turning rail 302, and the straight exit rail 303; a connecting plate 305 is also installed in the transmission belt 304, and the two ends of the connecting plate 305 are respectively connected to the straight entry rail 301 and the straight exit rail 303; The straight entry rail 301 includes an upper straight rail and a lower straight rail, both of which are "L"-shaped structures, and the upper straight rail and the lower straight rail cooperate with each other to form a "C"-shaped structure, and there is a gap between the upper straight rail and the lower straight rail, and the upper straight rail and the lower straight rail are connected by a frame; a side plate is provided on one side of the lower straight rail, and a transmission belt 304 is installed on one side of the side plate, and the transmission belt 304 is engaged with the rotating block 114; The shortest distance between the connecting plate 305 and the lower straight track is greater than the longest distance between the translation wheel 113 and the lower straight track. It should be noted that the function of the flipping slide rail is to flip the clamp 1 and the plate 4 clamped therein. The flipping slide rail can be connected between the two translation slide rails 2 before the process that needs to be flipped to realize the flipping of the plate 4. When the clamp 1 moves to the flipping slide rail, the clamp 1 is only driven by the rotating block 114. When entering the turning rail 302 from the straight entry rail 301, the translation wheel 113 at the forward end of the clamp 1 sinks first. As the clamp 1 continues to move, and the other translation wheel 113 gradually separates from the straight entry rail 301, the translation wheel 113 at the forward end slides into the turning rail 302. Since the turning rail 302 is a "human" shaped structure, when the translation wheel 113 at the forward end enters the lowest point of the turning rail 302, the other translation wheel 113 is at the highest point, and completes the flipping under the continued advancement of the rotating block 114, and enters the straight exit rail 303 to complete the flipping operation of the plate 4.

[0028] A production method for a pilot PCB production line comprises the following steps: Step 1: Determine the production process of the PCB board and determine the positions of all machines except the board 4 cutting process; Step 2: according to the production process, several translation slide rails 2 are spliced ​​and run through various processing machines; and the flipping slide rails are inserted into the front station of the process that requires flipping the plate 4; Step 3: Slide the cut plate 4 into the initial position and fix it with the clamp 1, start the drive belt 203 on the translation slide rail 2, slide the plate 4 fixed by the clamp 1 into the next station for processing, and conduct a pilot test of the PCB board production line. Record and file it after completion.
