Description

Technical Field

[0001] This invention relates to the field of conductive adhesive coating technology, and more specifically to a conductive adhesive coating apparatus and coating method. Background Technology

[0002] Conductive adhesive is an adhesive that has a certain degree of conductivity after curing or drying. It can connect various conductive materials together, forming an electrical path between the connected materials. In the electronics industry, conductive adhesive has become an indispensable new material.

[0003] The conductive adhesive is applied to the surface of the conductive material using a coating device, and then the conductive adhesive is evenly applied to the surface of the conductive material using a spreading mechanism. The conductive adhesive is used to connect the conductive materials, so that the wire materials can conduct electricity.

[0004] When coating the surface of conductive materials, if the material is placed directly on the worktable and then coated, the material is prone to displacement, which affects the coating effect. Therefore, in the prior art, when using a conductive adhesive coating device to coat conductive materials with conductive adhesive, a fixing fixture is often used to fix the material before the coating operation is performed.

[0005] A search revealed a utility model patent with publication number CN218742939U, which discloses a conductive adhesive coating device, relating to the field of conductive adhesive coating technology. This utility model includes a workbench with a first mounting groove at its top. A carrier plate is slidably connected inside the first mounting groove. A crossbar is fixedly mounted on one side of the top of the carrier plate. A first sliding groove is formed on one side of the crossbar, and a connecting rod is slidably connected inside the first sliding groove. A first fixing plate is fixedly mounted on one side of the connecting rod. A second mounting groove is formed inside the connecting rod, and a guide rod is fixedly mounted at its center. A connecting plate is slidably connected to the surface of the guide rod. Pressing an adjustment knob allows the connecting... The plate slides along the guide rod, the fixing rod is pulled out from the fixing groove on the surface of the crossbar, and the connecting rod slides along the first sliding groove, thereby adjusting the position of the first fixing plate. The first fixing plate and the second fixing plate are combined to limit and fix items of different sizes. Although the device can fix the conductive material to be coated to a certain extent, the operation is relatively cumbersome and inconvenient. Each time it is used, the conductive material must be manually placed on the worktable and then fixed, and then the coated conductive material must be removed. The use is cumbersome and it is difficult to effectively improve work efficiency. Therefore, the device still has certain shortcomings. Summary of the Invention

[0006] The purpose of this invention is to address the problem that while existing coating devices can provide some fixation for conductive materials, the process is cumbersome and inconvenient. Furthermore, each use requires manual placement of the conductive material on the worktable before fixing it, followed by removal of the coated material, making it inefficient and hindering work efficiency. Therefore, this invention provides a conductive adhesive coating device.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A conductive adhesive coating apparatus includes a worktable and a coating component.

[0009] The top of the workbench is connected to a three-axis displacement drive mechanism via a vertical plate, and the coating component is connected to the output end of the three-axis displacement drive mechanism.

[0010] The top of the workbench is provided with a cross slide groove, and the bottom of the workbench is provided with a clamping component for fixing the workpiece. The output end of the clamping component passes through the workbench and extends upward, and the clamping component is slidably connected to the cross slide groove. The clamping component includes a support frame fixedly connected to the bottom of the workbench, a drive cylinder connected to the support frame, a first connecting rod connected between the output end of the drive cylinder and the support frame, and a clamping block connected to the output end of the first connecting rod.

[0011] The top of the workbench is also equipped with a feeding component that cooperates with the clamping component to realize automatic feeding of materials;

[0012] The top of the workbench is equipped with a conveying component that works in conjunction with the clamping component and the feeding component to transport materials.

[0013] As a further aspect of the present invention: the output end of the drive cylinder is connected to a fixed seat, one end of the first connecting rod is rotatably connected to the fixed seat, and the other end passes through the cross groove and extends upward.

[0014] As a further aspect of the present invention: a second connecting rod is fixedly connected to the outer wall of the support frame, and the end of the second connecting rod away from the support frame is rotatably connected to the first connecting rod.

[0015] As a further aspect of the present invention: the first connecting rod includes a first connecting rod and a second connecting rod slidably connected to the first connecting rod, and the first connecting rod and the second connecting rod are adjustablely connected by a locking bolt.

[0016] As a further aspect of the present invention: a connecting component is provided between the first connecting rod and the cross slide groove, which is connected to the clamping block and enables it to move and rotate along the cross slide groove.

[0017] As a further aspect of the present invention: the connecting assembly includes a cross slider slidably connected inside the cross groove, a first connecting seat is connected to the outer wall of the cross slider, the clamping block is rotatably connected to the cross slider through the first connecting seat, and the first connecting rod is rotatably connected to the clamping block through a second connecting seat.

[0018] As a further aspect of the present invention: the feeding component includes a storage box disposed on the top of the workbench, a feeding cylinder fixedly connected to the top of the workbench, and a pusher plate connected to the output end of the feeding cylinder and cooperating with the storage box, wherein the pusher plate is specifically an L-shaped structure.

[0019] As a further aspect of the present invention: the conveying component includes a groove formed on the top of the workbench and a drive roller disposed inside the groove for conveying materials.

[0020] As a further embodiment of the present invention: the three-axis displacement drive mechanism includes a first displacement component that moves along the X-axis and is connected to the top of the worktable via a vertical plate, a second displacement component that moves along the Y-axis and is disposed at the output end of the first displacement component, and a third displacement component that moves along the Z-axis and is disposed at the output end of the second displacement component. The coating component is connected to the outer wall of the output end of the third displacement component via a connecting sleeve.

[0021] A coating method for a conductive adhesive coating apparatus specifically includes the following steps:

[0022] S1: Place the workpiece to be inspected into the storage box above the worktable. At this time, the clamping component is in the open state. Start the feeding cylinder to drive the pusher plate to retract. Since the pusher plate has an L-shaped structure and the storage box is at a certain height from the worktable, when the pusher plate retracts, the workpiece inside the storage box will fall to the top of the worktable. Then start the feeding cylinder to push the pusher plate, which can push the single workpiece to the conveying component. The remaining workpieces inside the storage box will remain inside the storage box due to the obstruction of the L-shaped pusher plate. Start the conveying component to transport the pushed workpiece to the clamping component.

[0023] S2: The start-up drive cylinder moves the fixed seat connected to its output end downward. A second connecting rod is provided between the support frame and the first connecting rod. Therefore, when the drive cylinder moves the fixed seat downward, the end of the first connecting rod connected to the fixed seat moves downward and rotates with it. With the second connecting rod, the cross slider and the cross groove, the clamping block will slide along the cross groove towards the center of the worktable, thereby clamping and fixing the workpiece on the worktable to prevent it from moving during coating and affecting the coating quality. In addition, a rubber pad is provided on the inner wall of the clamping block to prevent damage to the workpiece when clamping it.

[0024] S3: Then, the first displacement component, the second displacement component, and the third displacement component are activated respectively to move the coating component along the XYZ axis, and the coating component performs the coating operation on the position to be coated.

[0025] S4: After the workpiece is coated, the drive cylinder is activated to retract, causing the fixed seat to move upward. The clamping block is rotatably connected to the cross slider through the first connecting seat. The first connecting seat has a closed bottom structure, so the clamping block can only rotate 90° along the first connecting seat. Therefore, when the drive cylinder is activated to move the fixed seat upward, the first connecting rod will first drive the clamping block to rotate along the first connecting seat under the action of the second connecting rod until the clamping block is in a horizontal state with the worktable. At this time, the drive cylinder continues to retract, and the first connecting rod will continue to rotate through the second connecting rod. This will drive the clamping block and the cross slider to move away from the center of the worktable along the cross slide groove, thereby releasing the fixation of the workpiece.

[0026] S5: The first connecting seat is a closed structure at the bottom, so the clamping block can only rotate 90° along the first connecting seat, so that it can be in a horizontal state or a vertical state with the worktable. There is a certain frictional resistance between the cross slider and the cross groove. When the drive cylinder is started to move downward to clamp the workpiece, it first drives the clamping block to rotate along the first connecting seat until it is perpendicular to the worktable. At this time, the workpiece is clamped and fixed. When the drive cylinder is started to move upward, it will first drive the clamping block to rotate along the first connecting seat until it is horizontal with the worktable, so that the coated workpiece can be transferred out of the coating position.

[0027] S6: The first connecting rod is composed of a first connecting rod and a second connecting rod, and the first connecting rod and the second connecting rod are connected by a locking bolt. Therefore, the length of the first connecting rod can be adjusted. When the relative position between the first connecting rod and the second connecting rod is adjusted, the position of the clamping block connected to it in the cross groove will also be adjusted accordingly. Therefore, the clamping component can be used to clamp and fix workpieces of different models, improving its practicality.

[0028] S7: After coating is completed, start the three-axis displacement drive mechanism to move the coating component away from the workpiece. Then start the drive roller to rotate, which can transfer the coated workpiece on the top of the worktable. The worker can then store it. Then start the feeding component again to feed the workpiece and fix it with the clamping component, so that the coating operation on the workpiece can be carried out continuously.

[0029] The beneficial effects of this invention are:

[0030] 1. The clamping components can be used to clamp and fix the workpiece to be coated in a convenient and quick manner. The first connecting rod is adjustable, so it can be used to fix different types of workpieces when the first connecting rod is adjusted.

[0031] 2. Through the set connecting components, the clamping block can rotate 90° along the first connecting seat, so that it can be in a horizontal state or a vertical state with the worktable. This facilitates the clamping and fixing of the workpiece, and at the same time, it facilitates the automatic feeding and unloading of the workpiece in conjunction with the feeding mechanism and the conveying components, effectively reducing the labor intensity of the work and improving the coating efficiency.

[0032] 3. By using the feeding components and the conveying components, a single workpiece can be transported to the clamping component position at one time, achieving automatic feeding, simplifying the operation process, reducing labor intensity, and improving work efficiency.

[0033] 4. The three-axis displacement drive mechanism can drive the coating component to move along the XYZ axis, and the coating component can be used to apply conductive adhesive to the workpiece to complete the coating operation. Attached Figure Description

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-8 As shown, a conductive adhesive coating apparatus includes a worktable 100 and a coating component 300.

[0047] The top of the worktable 100 is connected to a three-axis displacement drive mechanism 200 via a vertical plate 101. The coating component 300 is connected to the output end of the three-axis displacement drive mechanism 200. The three-axis displacement drive mechanism 200 can drive the coating component 300 to move along the XYZ axes, thereby completing the coating work on the workpiece.

[0048] The top of the workbench 100 is provided with a cross slide groove 102, and the bottom of the workbench 100 is provided with a clamping component 400 for fixing the workpiece. The output end of the clamping component 400 passes through the workbench 100 and extends upward, and the clamping component 400 is slidably connected to the cross slide groove 102. The clamping component 400 includes a support frame 401 fixedly connected to the bottom of the workbench 100, a drive cylinder 402 connected to the support frame 401, a first connecting rod 403 connected between the output end of the drive cylinder 402 and the support frame 401, and a clamping block 404 connected to the output end of the first connecting rod 403. The clamping component 400 can conveniently and quickly fix the workpiece to be coated, and is simple and convenient to use.

[0049] The top of the workbench 100 is also equipped with a feeding component 500 that works with the clamping component 400 to automatically feed materials.

[0050] The top of the workbench 100 is provided with a conveying component 600 that works in conjunction with the clamping component 400 and the feeding component 500 to convey materials.

[0051] Reference Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The output end of the drive cylinder 402 is connected to a fixed seat 405. One end of the first connecting rod 403 is rotatably connected to the fixed seat 405, and the other end passes through the cross slide groove 102 and extends upward.

[0052] Reference Figure 6-8 A second connecting rod 406 is fixedly connected to the outer wall of the support frame 401. The end of the second connecting rod 406 away from the support frame 401 is rotatably connected to the first connecting rod 403. The second connecting rod 406, which is configured to cooperate, can make the first connecting rod 403 rotate when the drive cylinder 402 is started, thereby driving the clamping block 404 to move along the cross slide groove 102, thereby realizing the clamping and fixing operation of the workpiece.

[0053] The first connecting rod 403 includes a first connecting rod 4031 and a second connecting rod 4032 slidably connected to the first connecting rod 4031. The first connecting rod 4031 and the second connecting rod 4032 are adjustablely connected by a locking bolt 4033. Since the first connecting rod 403 is composed of the first connecting rod 4031 and the second connecting rod 4032 and is fixed by the locking bolt 4033, the length of the first connecting rod 403 can be adjusted. Correspondingly, the position of the clamping block 404 connected to it in the cross groove 102 will also be adjusted accordingly. Therefore, the clamping component 400 can be used to clamp and fix workpieces of different types, improving its practicality.

[0054] A connecting assembly 410 is provided between the first connecting rod 403 and the cross slide 102, which is connected to the clamping block 404 so that it can move and rotate along the cross slide 102.

[0055] The connecting component 410 includes a cross slider 407 slidably connected inside the cross slide groove 102. A first connecting seat 408 is connected to the outer wall of the cross slider 407. The clamping block 404 is rotatably connected to the cross slider 407 through the first connecting seat 408. The first connecting rod 403 is rotatably connected to the clamping block 404 through the second connecting seat 409. The connecting component 410 enables the clamping block 404 to be in a horizontal or vertical state, thereby achieving the clamping and fixing of the workpiece while facilitating the loading and unloading of the workpiece.

[0056] Reference Figure 1-3 The feeding component 500 includes a storage box 501 disposed on the top of the workbench 100, a feeding cylinder 502 fixedly connected to the top of the workbench 100, and a pusher plate 503 connected to the output end of the feeding cylinder 502 and cooperating with the storage box 501. The pusher plate 503 is specifically an L-shaped structure.

[0057] Reference Figure 1 , Figure 2 and Figure 4 The conveying component 600 includes a groove 601 formed on the top of the worktable 100 and a drive roller 602 disposed inside the groove 601 for conveying materials. With the feeding component 500 and the conveying component 600 working together, a single workpiece can be conveyed to the clamping component 400 position at one time, achieving the effect of automatic feeding, simplifying the operation process, reducing labor intensity, and improving work efficiency.

[0058] Reference Figure 2 and Figure 3 The three-axis displacement drive mechanism 200 includes a first displacement component 201 connected to the top of the worktable 100 via a vertical plate 101 and moving along the X-axis, a second displacement component 202 disposed at the output end of the first displacement component 201 and moving along the Y-axis, and a third displacement component 203 disposed at the output end of the second displacement component 202 and moving along the Z-axis. The coating component 300 is connected to the outer wall of the output end of the third displacement component 203 via a connecting sleeve 204.

[0059] Specifically, when using the conductive adhesive coating device: First, the workpiece to be tested is placed into the storage box 501 above the worktable 100. At this time, the clamping component 400 is in the open state. The feeding cylinder 502 is started to drive the pusher plate 503 to retract. Since the pusher plate 503 has an L-shaped structure and the storage box 501 is at a certain height from the worktable 100, when the pusher plate 503 is retracted, the workpiece inside the storage box 501 will fall to the top of the worktable 100. Then, the feeding cylinder 502 is started to push the pusher plate 503, which can push a single workpiece onto the conveying component 600. The remaining workpieces inside the storage box 501 will remain inside the storage box 501 due to the obstruction of the L-shaped pusher plate 503. The conveying component 600 is started to transport the pushed workpiece to the clamping component 400.

[0060] The start-up drive cylinder 402 drives the fixed seat 405 connected to its output end to move downward. A second connecting rod 406 is provided between the support frame 401 and the first connecting rod 403. Therefore, when the drive cylinder 402 drives the fixed seat 405 to move downward, the end of the first connecting rod 403 connected to the fixed seat 405 moves downward and rotates with it. The second connecting rod 406, the cross slider 407, and the cross groove 102, together with these components, will drive the clamping block 404 to slide along the cross groove 102 toward the center of the worktable 100, thereby clamping and fixing the workpiece on the worktable 100 to prevent it from moving during coating and affecting the coating quality. In addition, a rubber pad 4041 is provided on the inner wall of the clamping block 404 to prevent damage to the workpiece when clamping it.

[0061] Then, the first displacement component 201, the second displacement component 202, and the third displacement component 203 are activated respectively to move the coating component 300 along the XYZ axis, and the coating component 300 performs the coating operation on the position to be coated.

[0062] After the workpiece is coated, the drive cylinder 402 is activated to retract, causing the fixed seat 405 to move upward. The clamping block 404 is rotatably connected to the cross slider 407 through the first connecting seat 408. The first connecting seat 408 has a closed bottom structure, so the clamping block 404 can only rotate 90° along the first connecting seat 408. Therefore, when the drive cylinder 402 is activated to move the fixed seat 405 upward, the first connecting rod 403, under the action of the second connecting rod 406, will first drive the clamping block 404 to rotate along the first connecting seat 408 until the clamping block 404 is in a horizontal state with the worktable 100. At this time, the drive cylinder 402 continues to retract, and the first connecting rod 403 will continue to rotate through the second connecting rod 406. This will drive the clamping block 404 and the cross slider 407 to move along the cross slide groove 102 away from the center of the worktable 100, thereby releasing the fixation of the workpiece.

[0063] The first connecting seat 408 has a closed bottom structure, so the clamping block 404 can only rotate 90° along the first connecting seat 408, so that it can be in a horizontal state or a vertical state with the worktable 100. There is a certain frictional resistance between the cross slider 407 and the cross groove 102. When the drive cylinder 402 is started to move downward to clamp the workpiece, it first drives the clamping block 404 to rotate along the first connecting seat 408 until it is perpendicular to the worktable 100. At this time, the workpiece is clamped and fixed. When the drive cylinder 402 is started to move upward, it first drives the clamping block 404 to rotate along the first connecting seat 408 until it is horizontal with the worktable 100, which makes it easier to transfer the coated workpiece out of the coating position.

[0064] The first connecting rod 403 is composed of a first connecting rod 4031 and a second connecting rod 4032, and the first connecting rod 4031 and the second connecting rod 4032 are connected by a locking bolt 4033. Therefore, the length of the first connecting rod 403 can be adjusted. When the relative position between the first connecting rod 4031 and the second connecting rod 4032 is adjusted, the position of the clamping block 404 connected to it in the cross groove 102 will also be adjusted accordingly. Therefore, the clamping component 400 can be used to clamp and fix workpieces of different types, improving its practicality.

[0065] After coating is completed, the three-axis displacement drive mechanism 200 is activated to move the coating component 300 to a position away from the workpiece. Then, the drive roller 602 is activated to rotate, which can transport the coated workpiece on the top of the worktable 100. The worker can then collect it. Then, the feeding component 500 is activated again to feed the workpiece and the clamping component 400 is used to fix it, so that the coating operation on the workpiece can be carried out continuously.
