Description

Technical Field

[0001] This invention relates to the field of adhesive application technology for plastic parts, specifically to a flow-type adhesive application equipment and method for plastic parts. Background Technology

[0002] Plastic parts refer to all kinds of injection molded products produced by injection molding machines, including various packaging, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and various organic solvents are added.

[0003] For precision functional components in mobile terminal products such as mobile phones, tablets, and displays, which are divided into plastic parts and metal parts, adhesive strips are applied to the surface of plastic parts during the production process to provide protection. However, due to the low level of processing, some factories use semi-automatic adhesive application equipment, which requires manual placement of plastic parts on the equipment for adhesive application. On the one hand, manual feeding reduces the overall adhesive application rate of plastic parts, and on the other hand, human intervention increases the probability of accidents and can easily lead to personnel injuries.

[0004] Some manufacturers use fully manual gluing operations, with plastic parts being processed and glued on an assembly line. The intermediate process involves manual transfer, which reduces the overall gluing speed of plastic parts. At the same time, manual gluing operations increase the gluing error rate of some irregularly shaped plastic parts, which can easily lead to problems such as poor adhesion and delamination of plastic parts later on.

[0005] Therefore, we propose a flow-through adhesive application equipment and method for plastic parts. Summary of the Invention

[0006] The purpose of this invention is to provide a flow-type adhesive application equipment and method for plastic parts, so as to solve the problems mentioned in the background art above;

[0007] 1. The components on the movable plate perform a fully automatic adhesive application operation on the plastic parts fixed on the three-jaw chuck, avoiding the problem of low speed when applying adhesive manually.

[0008] 2. By adjusting the rotation direction of the entire turntable and the orientation of the limiting plate and the limiting block, the entire process adhesive application equipment can perform feeding and adhesive application operations on various irregularly shaped plastic parts, thus avoiding the problem of the limited application range of the entire process adhesive application equipment for plastic parts.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A plastic parts flow-type adhesive application processing equipment includes a worktable, on one side of the top of the worktable symmetrically provided with slides, and an adhesive application mechanism is slidably connected within the slides.

[0011] The adhesive applicator includes a movable plate, a placement tray, a cylinder assembly, and an electric push rod. The movable plate is slidably connected within the slide rail, and the placement tray is movably connected to the top side of the movable plate via a bearing. A guide column is fixed to the top of the movable plate by bolts, and a cylinder assembly is also fixed to the top of the movable plate. A stop block, a cutting head, and a telescopic roller are respectively fixed to one side of the cylinder assembly by bolts. An electric push rod is fixed to the top of the movable plate by bolts.

[0012] One end of the electric push rod is slidably connected to a clamping head, and a movable groove is provided inside the clamping head. A slot block is slidably connected inside the movable groove. One end of the electric push rod passes through one side of the clamping head and is connected to one side of the slot block by electric welding. A clamping block is symmetrically slidably connected to the inner wall of one side of the movable groove, and one side of the clamping block passes through the clamping head and is slidably connected to the clamping head.

[0013] Furthermore, a third spring is installed on the opposite surfaces of the two clamping blocks, and an abutment post is symmetrically fixed on one side of the electric push rod by spot welding, with the abutment post corresponding to the clamping head.

[0014] Furthermore, a linkage mechanism is movably connected to the top of the worktable via bearings. The linkage mechanism includes a turntable, an arc-shaped groove, a first rotating rod, a second rotating rod, and a locking block. The turntable is movably connected to the top of the worktable via bearings, and a circular groove is formed on the top of the turntable. Arc-shaped grooves are symmetrically formed within the circular groove. The first rotating rod is movably connected to one side of the turntable via bearings. The second rotating rod is movably connected to the top of the worktable via bearings, and one end of the first rotating rod is movably connected to one side of the second rotating rod via a bearing. A locking block is installed within the circular groove, and a first spring is installed on one side of the locking block. One side of the first spring is connected to one side of the worktable.

[0015] Furthermore, a sliding rod is fixed to the top of the workbench by spot welding, and a clamping mechanism is installed on the sliding rod.

[0016] Furthermore, the clamping mechanism includes a sliding sleeve rod, a connecting plate, a telescopic rod, and a limiting block. The sliding sleeve rod is slidably connected to the sliding sleeve rod, and the connecting plate is fixed to the bottom of the sliding sleeve rod by spot welding. The top of the connecting plate is fixed to the fixed clamping rod by spot welding, and the other side of the top of the connecting plate is slidably connected to the movable clamping rod. The top of the sliding sleeve rod is fixed to the second spring by spot welding, and the telescopic rod is slidably connected to one end of the sliding sleeve rod. The top of the movable clamping rod passes through the sliding sleeve rod and is connected to the bottom of the telescopic rod. A lock is installed on the telescopic rod, and the limiting block is fixed to one end of the telescopic rod by bolts.

[0017] Furthermore, a first discharge port is provided at the top of the workbench and at the bottom of the sliding sleeve rod, and a conveyor is installed at the bottom of the first discharge port, with a lifting plate assembly installed inside the conveyor.

[0018] Furthermore, a three-jaw chuck is installed on the top of the workbench and on one side of the first discharge port and the movable plate. A second discharge port is opened on one side of the three-jaw chuck and on the workbench. A limit plate is fixed to the top of the workbench by bolts.

[0019] Furthermore, one end of the second rotating rod is engaged with one side of the sliding sleeve rod, a feeding box is installed on the top of the workbench, and a base plate is slidably connected to the bottom inner wall of the feeding box, and clamping strips are symmetrically slidably connected to one side of the base plate.

[0020] Furthermore, the opposing surfaces of the two clamping strips are fixed with a protective layer by adhesion, and a feeding plate is installed on the opposing surfaces of the two protective layers inside the feeding box, with a feeding port opened on one side of the feeding plate.

[0021] Furthermore, a limiting hole is provided on one side of the clamping bar, and a limiting post is installed in the limiting hole. An adjustment knob is installed on one side of the feeding box, and one side of the substrate passes through the feeding box and is rotatably connected to one side of the snap-fit ​​block through a bearing.

[0022] The processing method of this plastic parts flow-type adhesive bonding equipment is as follows:

[0023] S1. Adaptation and adjustment of the dimensions of related components and plastic parts:

[0024] First, place the plastic parts that need to be glued onto the feeding plate and connecting plate respectively. Then, adjust the squeezing strength of the clamping strips and movable clamping rods on the surface of the plastic parts according to their size. This ensures that the clamping strips feed the plastic parts and the movable clamping rods unfeed them. Turn the adjustment knob located on one side of the feeding box. The rotation of the adjustment knob causes the two limiting posts to move relative to each other or back to back, thereby controlling the distance between the two limiting posts. This causes the clamping strips that are engaged with the limiting posts to also start moving with the limiting posts. By controlling the distance between the limiting posts, the clamping tightness of the two clamping strips on the plastic parts can be adjusted.

[0025] At the same time, by pulling out and releasing the lock on the telescopic rod, the length of the entire telescopic rod can be adjusted. Since the fixed clamp rod on the entire connecting plate cannot be moved, one side of the movable clamp rod is connected to the telescopic rod, and the limiting block at one end of the telescopic rod abuts against the limiting plate. The longer the telescopic rod, the greater the pressure on the second spring, resulting in a smaller distance between the movable clamp rod and the fixed clamp rod, and a greater clamping pressure on both sides of the plastic part.

[0026] S2. Applying adhesive and cutting plastic parts:

[0027] After the pressure on the plastic part is adjusted, start the entire turntable. The turntable rotates and drives the clamping mechanism on the slide rod to move left and right. At the same time, when the clamping block contacts the arc groove in the circular groove, it is pulled by the first spring and the base plate is pulled, causing the clamping bar on the base plate to be adjusted by the limit post to clamp the plastic part on both sides and drive the plastic part to move towards the lower feed port.

[0028] The plastic part falls from the discharge port onto the three-jaw chuck on the worktable. The entire three-jaw chuck begins to clamp the bottom of the plastic part. The movable plate located in the slide rail begins to move closer to the plastic part on the three-jaw chuck. First, the electric push rod pushes the clamping head to contact and pull out the rubber strip on one side of the block. At the same time, the cutting head on the cylinder group cuts the rubber strip. Simultaneously, the cylinder group pushes the telescopic roller to push the cut rubber strip onto the surface of the plastic part. At the same time, the three-jaw chuck drives the plastic part to rotate left and right, so that the telescopic roller can completely adhere the rubber strip to the surface of the plastic part. At this time, the movable clamping rod and the fixed clamping rod, which are in the open state, contact the plastic part with the rubber strip. When the sliding rod moves to the left, the limit block is acted upon by the limit plate, causing the movable clamping rod to clamp the plastic part and transport the plastic part to the top of the first discharge port. The plastic part falls onto the conveyor table and is transported out.

[0029] S3. Applying adhesive to irregularly shaped plastic parts:

[0030] First, adjust the position of the entire limiting plate and limiting block. Then, remove the first spring that is clipped to the worktable and rotate the clipping block to disengage it from the circular groove. Move the irregular plastic part loading worktable to the conveyor table. After the irregular plastic part moves to the first discharge port, raise the plate assembly to push the plastic part to the top of the worktable. Change the rotation direction of the entire turntable from clockwise to counterclockwise. Send the irregular plastic part into the three-jaw chuck through the movable clamping rod. Then, apply adhesive to the surface of the irregular plastic part through the adhesive application mechanism. After the adhesive application is completed, the telescopic rollers on the entire cylinder assembly push the plastic part into the second discharge port, completing the unloading operation of the irregular plastic part.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. In this invention, the movable plate inside the slide rail drives the rubber strip pulled out by the clamping head to contact the surface of the plastic part. At the same time, the cutting head and telescopic roller on the cylinder group contact the rubber strip. The cutting head cuts the rubber strip, and the entire telescopic roller pushes the rubber strip to the surface of the plastic part, so that the entire rubber strip is attached to the surface of the plastic part. With the telescopic roller's own telescopicity and the rotation of the three-jaw chuck, the rubber strip is fully attached to the plastic part. Finally, the entire stop block fixes the cut rubber strip, which is conducive to the gripping of the entire clamping head. The entire plastic part gluing equipment has a high level of automation, which improves the overall gluing speed of plastic parts.

[0033] 2. In this invention, while the turntable rotates and drives the entire clamping mechanism to move left and right, the clamping block, which is clamped in the circular groove, pulls the substrate located in the loading box after contacting the arc groove. This causes the entire clamping bar to continuously clamp the plastic parts on the feeding plate and move them to the lower feeding port. At the same time, after the plastic parts that fall from the feeding port onto the three-jaw chuck are glued by the glue-applying mechanism, they are clamped and detached from the entire three-jaw chuck by the fixed clamping bar and the movable clamping bar on the moving sliding sleeve rod. Finally, the plastic parts on the sliding sleeve rod successfully fall from the first discharge port onto the conveyor table, completing the linkage of the entire plastic parts from loading to unloading before and after glue application, and improving the glue application and loading / unloading speed of the plastic parts.

[0034] 3. In this invention, by adjusting the rotation direction of the entire turntable and the orientation of the limiting plate and the limiting block, the entire process adhesive application equipment can perform adhesive application operations on various irregularly shaped plastic parts, avoiding the limitation that the entire feeding platform can only perform feeding operations on relatively regular plastic parts, thus expanding the scope of application of the entire equipment in plastic parts.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-9 The present invention provides a technical solution:

[0047] Example 1:

[0048] The entire process of applying adhesive to plastic parts, such as Figure 1 As shown, the entire workbench 1 is equipped with a loading box 7 for handling plastic parts, an adhesive applicator 18 for applying adhesive to plastic parts, and a clamping mechanism 4 for unloading plastic parts. In actual operation, in order to facilitate the clamping bars 11 in the entire loading box 7 and the fixed clamping rods 403 and movable clamping rods 404 in the clamping mechanism 4 to clamp and fix the plastic parts, a pre-adjustment operation is required.

[0049] The plastic parts to be glued are placed onto the feeding plate 8 and connecting plate 402 respectively. The clamping strip 11 and movable clamping rod 404 are adjusted according to the size of the plastic parts to ensure that the clamping strip 11 feeds the plastic parts and the movable clamping rod 404 unfeeds them. The adjusting knob 15, located on one side of the feeding box 7, is rotated. The knob 15 is connected to a threaded rod with opposite threads on both sides. Two limiting posts 14 are engaged with the threaded rod. Rotating the adjusting knob 15 causes the two limiting posts 14 to move relative to each other or in opposite directions, thus controlling the distance between them. This causes the limiting holes 13 engaged with the limiting posts 14 to move along with them. The clamping strip 11 is used to grip and transport the plastic parts. After the position of the two clamping strips 11 is adjusted, the operator places the plastic parts onto the feeding plate 8 inside the feeding box 7. Figure 2 As shown, the turntable 201 on the entire workbench 1 begins to rotate. A circular groove 202 is formed on the turntable 201, and symmetrical arc-shaped grooves 203 are formed within the circular groove 202. A locking block 207 is engaged within the circular groove 202. A base plate 10 inside the loading box 7 is movably connected to the locking block 207. Simultaneously, a first spring 206 is installed on the entire workbench 1, with one end of the first spring 206 connected to one side of the locking block 207. The tension generated by the first spring 206 causes the locking block 207 to press tightly against the inner ring of the circular groove 202. When the entire turntable 201 begins to rotate, the locking block... After 207 contacts the arc groove 203 in the circular groove 202, the first spring 206 pulls the entire snap-fit ​​block 207 to move inward, causing the entire snap-fit ​​block 207 to pull the substrate 10 located in the feeding box 7. When the substrate 10 moves outward, the clamping strips 11 on the substrate 10 begin to move towards each other due to the constraint of the limiting post 14, clamping the plastic parts placed on the feeding plate 8 on both sides and moving towards the feeding port 9. The inner wall of the clamping strips 11 is adhered with a protective layer 12. The entire protective layer 12 is made of relatively soft sponge, which prevents the clamping strips 11 from damaging the plastic parts while increasing the contact area between the clamping strips 11 and the surface of the plastic parts.

[0050] Additionally, to prevent the clamping bar 11 from pushing the plastic part away from the feed port 9 after the entire substrate 10 moves inward, the entire feeding plate 8 can be processed and improved so that the friction is small when the entire plastic part moves outward on the feeding plate 8, and the friction increases when the entire plastic part moves inward on the feeding plate 8. In this way, the entire plastic part will be pushed by the clamping bar 11 towards the feed port 9. This improvement of the feeding plate 8 can be achieved by pasting paper on the plate surface and adjusting the smoothness of both sides of the paper.

[0051] After the clamping bar 11 inside the entire feeding box 7 is adjusted, the length of the entire telescopic rod 406 is adjusted by pulling out the lock 408 on the telescopic rod 406. Since the fixed clamping rod 403 on the entire connecting plate 402 cannot be moved, one side of the movable clamping rod 404 is connected to the telescopic rod 406, and the limiting block 407 at one end of the telescopic rod 406 abuts against the limiting plate 5. The longer the telescopic rod, the greater the pressure on the second spring 405, which results in a smaller distance between the movable clamping rod 404 and the fixed clamping rod 403, and a greater clamping pressure on both sides of the plastic part.

[0052] After the clamping bar 11 and the movable clamping rod 404 are adjusted, the clamping bar 11 successfully clamps the plastic part to the discharge port 9. The discharge port 9 on the entire feeding plate 8 is connected to the three-jaw chuck 16 on the worktable 1. The plastic part falls directly onto the three-jaw chuck 16, and the adhesive application operation of the entire plastic part begins at this time. Figure 4 As shown, after the entire turntable 201 begins to rotate 180 degrees clockwise, the first rotating rod 204 in the linkage mechanism 2 on the turntable 201 pushes the second rotating rod 205 on the worktable 1, causing the second rotating rod 205 to drive the clamping mechanism 4 on the slide rod 3 to move to the left. The limiting block 407 on the clamping mechanism 4 moves to the left side of the limiting plate 5, and the movable clamping rod 404 places the plastic part on the conveyor 26 in the first discharge port 6. At this time, the entire locking block 207 locks the plastic part when the turntable 201 rotates 180 degrees. When the receiving block 207 contacts the arc groove 203 once, the clamping bar 11 pulls the new plastic part once, but the new plastic part does not go from the discharge port 9 to the three-jaw chuck 16. When the turntable 201 rotates 180 degrees again, the receiving block 207 contacts the arc groove 203 again. At this time, the clamping bar 11 pulls the new plastic part, causing the plastic part to fall into the three-jaw chuck 16. While the limiting block 407 is moving to the right side of the limiting plate 5, the entire adhesive applicator 18 applies the new plastic part and waits for the contact of the movable clamping bar 404.

[0053] like Figure 6 As shown, a connecting plate 402 is installed at the bottom of the entire sliding sleeve rod 401, and a movable clamping rod 404 is slidably connected to the connecting plate 402, and a fixed clamping rod 403 is fixedly connected. At the same time, the top of the entire movable clamping rod 404 is connected to the bottom of the sliding sleeve rod 401, and one end of the telescopic rod 406 abuts against the second spring 405. When the limiting block 407 at one end of the entire telescopic rod 406 abuts against the bottom of the limiting plate 5, the entire telescopic rod 406 pushes the second spring 405, and the distance between the movable clamping rod 404 and the fixed clamping rod 403 decreases, so that the entire fixed clamping rod 403 and the movable clamping rod 404 can clamp the plastic part.

[0054] Example 2:

[0055] After the entire plastic part falls onto the three-jaw chuck 16, the adhesive applicator 18 located in the slide 17 of the worktable 1 begins to move onto the three-jaw chuck 16, as... Figure 5 As shown, the top of the movable plate 181 on the entire adhesive applicator 18 is movably connected to the placement plate 182 via bearings. The top of the placement plate 182 is equipped with two adjustable clamping posts. The placement plate 182 is used to fix the adhesive strip roll. At the same time, the top of the movable plate 181 is equipped with two guide posts 183. The guide posts 183 are used to guide the adhesive strip. The guide posts 183 guide the adhesive strip on the adhesive strip roll to one side of the abutment block 185.

[0056] The top of the entire movable plate 181 is bolted with a cylinder assembly 184. Simultaneously, from right to left, a stop block 185, a cutting head 186, and a telescopic roller 187 are sequentially installed on the cylinder assembly 184. An electric push rod 188 is installed opposite the stop rod, and a clamping head 19 is installed at one end of the electric push rod 188. Figure 7 As shown, a movable groove 20 is provided inside the entire clamping head 19, and one end of the electric push rod 188 passes through the clamping head 19 and is connected to one side of the slot block 21 in the movable groove 20. At the same time, clamping blocks 22 are symmetrically slidably connected on the inner wall of the entire movable groove 20. A third spring 23 is installed between the two clamping blocks 22. Meanwhile, one side of the entire clamping block 22 passes through the clamping head 19 and extends to one side of the clamping head 19.

[0057] When the entire electric push rod 188 pushes the clamping head 19 to contact the cut rubber strip on one side of the abutment block 185, the clamping head 19 contacts the abutment block 185 and the entire slot block 21 will also move in the movable groove 20 in the clamping head 19, so that the entire slot block 21 begins to contact the two clamping blocks 22. Since the slot block 21 has a slot on one side, the two clamping blocks 22 begin to move towards each other under the restriction of the slot block 21 and enter the slot of the slot block 21 at the same time, which eventually causes one end of the clamping block 22 to clamp the rubber strip. When the entire electric push rod 188 drives the clamping head 19 to retract, the clamping head 19 contacts the abutment post 24 on the electric push rod 188, causing the clamping block 22 to be pushed out from the slot block 21. After the action of the third spring 23 between the clamping blocks 22, the clamping blocks 22 unfold and the rubber strip falls off the clamping block 22.

[0058] When the clamping head 19 pulls the adhesive strip, the cutting head 186 on the cylinder assembly 184 cuts the adhesive strip pulled out by the clamping head 19. At the same time, the entire movable plate 181 has moved to the vicinity of the plastic part. The telescopic roller 187 on the cylinder assembly 184 begins to push the adhesive strip to contact the surface of the plastic part. At the same time, the entire three-jaw chuck 16 begins to rotate. The entire three-jaw chuck 16 fixes the bottom position of the entire plastic part. At the same time, sponges are fixed on the entire three-jaw chuck 16 to prevent the entire plastic part from being damaged. Since the telescopic roller 187 has a spring installed inside, it is pressed against the surface of the plastic part by the spring during the rotation of the entire plastic part, and presses the adhesive strip onto the surface of the plastic part, completing the adhesive application operation of the entire plastic part.

[0059] Example 3:

[0060] Because some plastic parts have slightly complex structures, relying solely on the clamping strips 11 inside the feeding box 7 to feed the plastic parts can easily lead to deviations, causing the plastic parts to fail to be unloaded normally. In this case, the plastic parts are fed through the conveyor 26 at the bottom of the first discharge port 6 at the top of the entire workbench 1. The plastic parts are then transported by cooperating with the entire clamping mechanism 4. Finally, the plastic parts with adhesive applied are unloaded by the telescopic rollers 187 on the cylinder group 184.

[0061] In specific operation, the conveyor 26 moves the plastic part to the bottom of the first discharge port 9. At this time, the lifting plate assembly 27 on the conveyor 26 lifts the plastic part upward and pushes it between the movable clamping rod 404 and the fixed clamping rod 403. Figure 9 As shown, by rotating the entire limiting plate 5 and the limiting block 407 on the telescopic rod 406 to face the same direction, and changing the rotation direction of the entire turntable 201, the movable clamping rod 404 on the entire sliding sleeve rod 401 clamps the plastic part on the lifting plate assembly 27 during the rightward movement, and at the same time sends the entire plastic part into the three-jaw chuck 16. After the adhesive application work of the adhesive application mechanism 18, the telescopic roller 187 on the cylinder assembly 184 pushes the adhesive-applied plastic part to fall into the second discharge port 25, completing the unloading of the entire plastic part.

2. The plastic parts flow-type adhesive application equipment according to claim 1, characterized in that: The processing method of this plastic parts flow-type adhesive bonding equipment is as follows: S1 related components and plastic parts size adaptation and adjustment First, place the plastic parts that need to be glued onto the feeding plate and connecting plate respectively. Then, adjust the squeezing strength of the clamping strips and movable clamping rods on the surface of the plastic parts according to their size. This ensures that the clamping strips feed the plastic parts and the movable clamping rods unfeed them. Turn the adjustment knob located on one side of the feeding box. The rotation of the adjustment knob causes the two limiting posts to move relative to each other or back to back, thereby controlling the distance between the two limiting posts. This causes the clamping strips that are engaged with the limiting posts to also start moving with the limiting posts. By controlling the distance between the limiting posts, the clamping tightness of the two clamping strips on the plastic parts can be adjusted. At the same time, by pulling out and releasing the lock on the telescopic rod, the length of the entire telescopic rod can be adjusted. Since the fixed clamp rod on the entire connecting plate cannot be moved, one side of the movable clamp rod is connected to the telescopic rod, and the limiting block at one end of the telescopic rod abuts against the limiting plate. The longer the telescopic rod, the greater the pressure on the second spring, resulting in a smaller distance between the movable clamp rod and the fixed clamp rod, and a greater clamping pressure on both sides of the plastic part. Applying adhesive and cutting S2 plastic parts After the pressure on the plastic part is adjusted, start the entire turntable. The turntable rotates and drives the clamping mechanism on the slide rod to move left and right. At the same time, when the clamping block contacts the arc groove in the circular groove, it is pulled by the first spring and the base plate is pulled, causing the clamping bar on the base plate to be adjusted by the limit post to clamp the plastic part on both sides and drive the plastic part to move towards the lower feed port. The plastic part falls from the discharge port onto the three-jaw chuck on the worktable. The entire three-jaw chuck begins to clamp the bottom of the plastic part. The movable plate located in the slide rail begins to move closer to the plastic part on the three-jaw chuck. First, the electric push rod pushes the clamping head to contact and pull out the rubber strip on one side of the block. At the same time, the cutting head on the cylinder group cuts the rubber strip. Simultaneously, the cylinder group pushes the telescopic roller to push the cut rubber strip onto the surface of the plastic part. At the same time, the three-jaw chuck drives the plastic part to rotate left and right, so that the telescopic roller can completely adhere the rubber strip to the surface of the plastic part. At this time, the movable clamping rod and the fixed clamping rod, which are in the open state, contact the plastic part with the rubber strip. When the sliding rod moves to the left, the limit block is acted upon by the limit plate, causing the movable clamping rod to clamp the plastic part and transport the plastic part to the top of the first discharge port. The plastic part falls onto the conveyor table and is transported out. Applying adhesive to S3 irregularly shaped plastic parts First, adjust the position of the entire limiting plate and limiting block. Then, remove the first spring that is clipped to the worktable and rotate the clipping block to disengage it from the circular groove. Move the irregular plastic part loading worktable to the conveyor table. After the irregular plastic part moves to the first discharge port, raise the plate assembly to push the plastic part to the top of the worktable. Change the rotation direction of the entire turntable from clockwise to counterclockwise. Send the irregular plastic part into the three-jaw chuck through the movable clamping rod. Then, apply adhesive to the surface of the irregular plastic part through the adhesive application mechanism. After the adhesive application is completed, the telescopic rollers on the entire cylinder assembly push the plastic part into the second discharge port, completing the unloading operation of the irregular plastic part.
