Description

Technical Field

[0001] This invention relates to the field of vacuum dispensing equipment technology, and in particular to a novel vacuum dispensing machine. Background Technology

[0002] Chinese Utility Model Patent No. ZL202320575845.8, entitled "Dispensing Equipment," discloses a vacuum dispensing device. Specifically, the device includes a frame, a feeding conveyor, a dispensing unit, a transfer device, and a lifting device. The feeding conveyor transports the product to be dispensed. The dispensing unit includes a dispensing conveyor and a dispensing mechanism, which connects to an external dispensing device. The dispensing conveyor includes a dispensing linear assembly, a positioning bracket, and a positioning mechanism. The dispensing linear assembly is mounted on the frame, with one end corresponding to the feeding conveyor. The positioning bracket is mounted on the dispensing linear assembly and moves under its drive. The positioning mechanism slides on the positioning bracket in a direction perpendicular to the dispensing linear assembly. The transfer device is used to transfer the product from the feeding conveyor... The device grips the product to be glued and places it on the positioning mechanism. A lifting device is located on the frame and adjacent to the other end of the glue-dispensing linear assembly. When the glue-dispensing linear assembly drives the positioning bracket and positioning mechanism to move to the other end of the glue-dispensing linear assembly, the lifting device connects with the positioning mechanism to drive the positioning mechanism to move on the positioning bracket. The glue-dispensing device also includes a housing and an air extraction mechanism. The housing is located on the frame and above the other end of the glue-dispensing linear assembly. One end of the glue-dispensing mechanism is inserted into the housing, and the other end of the glue-dispensing mechanism is connected to an external glue supply device. The air extraction mechanism is connected to the housing. The lifting device drives the positioning mechanism to move and abut against the housing, so that the housing and the positioning mechanism are connected to form a sealed cavity. The air extraction mechanism is used to extract air from the cavity to create a vacuum environment inside the cavity. The glue-dispensing mechanism is used to dispense glue onto the product to be glued in the vacuum environment.

[0003] In addition, the dispensing mechanism includes a dispensing needle and a dispensing assembly coaxially connected to the dispensing needle. One end of the dispensing needle is inserted into the housing, and the dispensing assembly is fixed to the housing and connected to the other end of the dispensing needle. The dispensing assembly is used to connect with an external dispensing device.

[0004] During the vacuum dispensing operation of the aforementioned dispensing equipment, the feeding conveyor transports the product to be dispensed to a position corresponding to one end of the dispensing linear assembly. The dispensing linear assembly drives the positioning bracket and positioning mechanism to move to one end of the dispensing linear assembly. The transfer device grabs the product to be dispensed from the feeding conveyor and places it on the positioning mechanism. The dispensing linear assembly drives the positioning bracket and the positioning mechanism carrying the product to be dispensed to move together to the other end of the dispensing linear assembly, connecting the positioning mechanism with the lifting device. The lifting device drives the positioning mechanism to move until the positioning mechanism abuts against the housing and forms a sealed cavity. Then, the vacuuming mechanism evacuates the cavity so that the product to be dispensed in the cavity is in a vacuum environment. The dispensing mechanism dispenses the product to be dispensed in the vacuum environment. After dispensing is completed, the vacuuming mechanism breaks the vacuum in the cavity to restore the cavity to a non-vacuum environment.

[0005] It should be noted that the above-mentioned dispensing equipment has the following defects, specifically: Defect 1: During operation, the product to be glued needs to be transferred to the glue-filling position using a feeding conveyor, a transfer device, a glue-filling linear assembly, a positioning mechanism, and a lifting device. When a vacuum chamber is formed and the glue-filling action is performed, the product consists of a jig and a workpiece carried in the jig. In order to ensure the accuracy of the transfer action and the glue-filling operation, the manufacturer must customize a jig that is compatible with the workpiece, and the workpiece must be accurately positioned on the jig before transfer. This seriously restricts the versatility and adaptability of the glue-filling equipment. Defect 2: Because the dispensing mechanism adopts a fixed structure design, it cannot dispense glue to multiple products, nor can it automatically identify the product position and dispense glue to products in different positions, resulting in low dispensing efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a novel vacuum dispensing machine that addresses the shortcomings of existing technologies. This novel vacuum dispensing machine features a novel structural design and high dispensing efficiency.

The automatic locking mechanism includes a locking fixing block mounted on the frame. The locking fixing block has a locking groove with a forward opening. A locking drive cylinder is mounted on the side of the locking fixing block next to the locking groove. The locking block is mounted on the drive end of the locking drive cylinder. During operation, when the turnover trolley moves to the designated position, the two frame locking rods are respectively inserted into the locking grooves of the corresponding locking fixing blocks, and each locking drive cylinder drives the corresponding locking block to move, so that each frame locking rod is locked in the locking groove of the corresponding side by the locking block.

[0013] Each of the fixed blocks is equipped with a guide wheel assembly on the front side of the corresponding locking groove.

[0014] The lifting drive mechanism includes a left lifting seat and a right lifting seat that are slidably mounted on the frame via guide pairs.

Detailed Implementation

[0034] The present invention will now be described in conjunction with specific embodiments.

[0035] Example 1, as Figure 1 and Figure 2 As shown, a novel vacuum dispensing machine includes a frame 1, a glue supply system 2, a vacuuming mechanism (not shown in the figure), an automatic glue dispensing component 3, and a product transfer component 4. The glue supply system 2, the vacuuming mechanism, the automatic glue dispensing component 3, and the product transfer component 4 are respectively installed on the frame 1.

[0036] The vacuuming mechanism includes a vacuum pump, and the automatic glue dispensing assembly 3 includes a glue dispensing head 31, which is connected to the glue supply system 2 via a glue delivery pipe.

[0037] Furthermore, such as Figures 1 to 3 As shown, a fixed platform 11 arranged horizontally is provided at the upper end of the frame 1. A sealed upper cover 5 is installed above the fixed platform 11. The fixed platform 11 and the sealed upper cover 5 together form a glue-filling operation chamber 6. A vacuum pump is connected to the glue-filling operation chamber 6 through a vacuum pipe. A CCD industrial camera 34 is installed inside the glue-filling operation chamber 6.

[0038] Furthermore, such as Figures 2 to 5 As shown, the automatic dispensing assembly 3 is located in the dispensing operation chamber 6. The automatic dispensing assembly 3 also includes a dispensing fixing bracket 32 ​​that is fastened to the fixing platform 11. The dispensing fixing bracket 32 ​​is equipped with an XY horizontal moving platform 33. The drive end of the XY horizontal moving platform 33 is equipped with a vertically moving Z-axis drive linear module 35. The dispensing head 31 is installed at the drive end of the Z-axis drive linear module 35.

[0039] In addition, such as Figure 2 , Figure 3 , Figure 6 as well as Figure 8 As shown, a vertical through hole 111 is provided in the middle of the fixed platform 11, and an annular sealing gasket 7 in a full-circumference shape is installed on the lower surface of the fixed platform 11, which surrounds the lower opening of the platform through hole 111.

[0040] And also, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 As shown, the product transfer assembly 4 includes a lifting platform 41 located below the fixed platform 11 and a turnover trolley 42 for placing loading pallets 46 in layers from top to bottom. The upper surface of the lifting platform 41 is equipped with a pallet pushing and pulling mechanism 43. The frame 1 is equipped with a lifting drive mechanism 44 corresponding to the lifting platform 41, and the lifting drive mechanism 44 is drivenly connected to the lifting platform 41.

[0041] It should be explained that the CCD industrial camera 34 in this embodiment can be installed in the following two ways: Method 1, the CCD industrial camera 34 is installed on the drive end of the XY horizontal moving platform 33; Method 2, a camera bracket is installed in the glue dispensing chamber 6 and is fastened to the sealed upper cover 5, and the CCD industrial camera 34 is fastened to the camera bracket.

[0042] It should be noted that the new vacuum dispensing machine is equipped with a controller 100, and the glue supply system 2, vacuum pump, XY horizontal moving platform 33, Z-axis drive linear module 35, and CCD industrial camera 34 are electrically connected to the controller 100.

[0043] The following is a detailed description of the novel vacuum dispensing machine in Embodiment 1, with reference to the specific working process. The specific steps are as follows: Step a: The staff places the product to be glued on the loading pallet 46, and places the loading pallet 46 containing the product to be glued on the turnover trolley 42 in layers from top to bottom; Step b: Move the turnover trolley 42 loaded with the product to be glued to the designated position, and position the turnover trolley 42 in front of the pallet push-pull mechanism 43; Step c: The lifting drive mechanism 44 drives the lifting platform 41 to move up and down, and makes the pallet push-pull mechanism 43 of the lifting platform 41 aligned with one of the loading pallets 46 on the turnover trolley 42. Step d: After the lifting platform 41 is lifted and moved into place under the driving action of the lifting drive mechanism 44, the pallet push-pull mechanism 43 is activated and pulls the aligned loading pallet 46 onto the lifting platform 41. Step e: After the pallet push-pull mechanism 43 pulls the loading pallet 46 onto the lifting platform 41, the lifting drive mechanism 44 drives the lifting platform 41 to move upward, so that the loading pallet 46 containing the product to be glued moves upward to the upper limit position along with the lifting platform 41; wherein, when the lifting drive mechanism 44 drives the lifting platform 41 to move upward to the upper limit position, the loading pallet 46 on the lifting platform 41 is located below the platform through hole 111, and the edge of the lifting platform 41 contacts and presses against the annular sealing gasket 7, so that the glue dispensing chamber 6 forms a sealed space; Step f: After the lifting platform 41 moves to the upper limit position and the lifting platform 41 contacts the pressing annular sealing gasket 7, the vacuum pump is started and the glue-drinking operation chamber 6 is evacuated. Step g: After the vacuuming process is completed, the automatic dispensing assembly 3 sequentially dispenses glue to the products on the loading tray 46. During this process, the glue supply system 2 supplies glue to the dispensing head 31, and the XY horizontal moving platform 33 drives the Z-axis driving linear module 35 and the dispensing head 31 to move horizontally. During this process, the CCD industrial camera 34 identifies the position of the products on the loading tray 46 and feeds the product position information back to the controller 100. The controller 100 adjusts the horizontal position of the dispensing head 31 according to the determined product position information and moves the dispensing head 31 horizontally to directly above the product to be dispensed. Then, the Z-axis driving linear module 35 drives the dispensing head 31 to move down to the dispensing operation position and dispenses glue to the product with the determined position. That is, the dispensing operation of each product in the loading tray 46 is completed sequentially in the manner of identifying the position first and then dispensing glue. Step h: After all products in the loading pallet 46 have completed the glue-filling operation, the vacuum pump stops and the glue-filling chamber 6 returns to normal air pressure. Then, the lifting drive mechanism 44 drives the lifting platform 41 to move down and causes the loading pallet 46 containing the glue-filled products to move down to the initial position. Then, the pallet push-pull mechanism 43 moves and pushes the loading pallet 46 containing the glue-filled products to the original position of the turnover trolley 42. Step i: Follow step ch to complete the glue-filling operation of the other products to be glued on the loading tray 46 in sequence.

[0044] It should be emphasized that in the process of applying glue to products using the novel vacuum dispensing machine of this embodiment, this embodiment adopts a method of identifying the position first and then dispensing glue to sequentially dispense the products on the loading tray 46. The dispensing head 31 is driven by the XY horizontal moving platform 33 and the Z-axis drive linear module 35, that is, the dispensing head 31 can realize XYZ three-axis movement. In other words, the automatic dispensing component 3 of this embodiment can accurately dispense glue to multiple products on the loading tray 46, and the dispensing efficiency is high. In addition, this embodiment does not require the use of fixtures to position the products. When placing the products to be dispensed on the loading tray 46, the operator only needs to place the products randomly according to the specified direction. This can save the cost of fixture development and the need to develop different fixtures for different products. It has good versatility and applicability.

[0045] In summary, the novel vacuum dispensing machine of this embodiment has the advantages of novel structural design and high dispensing efficiency through the above structural design.

[0046] Example 2, as Figure 9 and Figure 10 As shown, the difference between this embodiment 2 and embodiment 1 is that: the pallet push-pull mechanism 43 includes a push-pull movable frame 431 that is slidably mounted on the lifting platform 41 via a guide pair 8. The push-pull movable frame 431 is equipped with a push-pull walking drive motor 432, and the power output shaft of the push-pull walking drive motor 432 is equipped with a drive gear 433. The push-pull walking drive motor 432 is electrically connected to the controller 100. When working, the controller 100 controls the push-pull walking drive motor 432 to move.

[0047] Among them, the lifting platform plate 41 is screwed with a drive rack 434 that extends horizontally along the front-back direction, and the drive gear 433 meshes with the drive rack 434.

[0048] In addition, a pallet claw 435 is mounted on the front side of the push-pull moving drive motor 432 via a guide pair 8; the push-pull moving frame 431 is equipped with a lifting drive cylinder 436 for lifting action corresponding to the pallet claw 435, and the drive end of the lifting drive cylinder 436 is connected to the pallet claw 435.

[0049] In the process of pushing and pulling the loading pallet 46 using the pallet push-pull mechanism 43 of this embodiment, when it is necessary to pull the loading pallet 46 from the turnover trolley 42 onto the lifting platform 41, the push-pull driving motor 432 drives the driving gear 433 to rotate. The rotating driving gear 433 moves forward along the driving gear 433, thereby causing the push-pull movable frame 431, pallet claw 435, and lifting drive cylinder 436 to move forward synchronously. When the pallet claw 435 moves to the position of the loading pallet 46 to be pulled out, the push-pull mechanism 432 drives the loading pallet 46 to rotate. The pull drive motor 432 stops operating and the lifting drive cylinder 436 drives the pallet claw 435 to move downward so that the pallet claw 435 hooks the loading pallet 46. After the pallet claw 435 hooks the loading pallet 46, the push-pull drive motor 432 drives the drive gear 433 to rotate in the opposite direction so that the push-pull movable frame 431 moves backward to the initial position. During this process, the pallet claw 435 pulls the loading pallet 46 backward, thereby causing the loading pallet 46 containing the product to be glued to be pulled out onto the lifting platform 41.

[0050] When the loading pallet 46 containing the glued product needs to be pushed to the turnover trolley 42, the pallet claw 435 first holds the loading pallet 46, and the push-pull drive motor 432 drives the drive gear 433 to rotate. The rotating drive gear 433 moves forward along the drive gear 433, thereby causing the push-pull movable frame 431, the pallet claw 435, the lifting drive cylinder 436, and the loading pallet 46 to move forward synchronously. When the loading pallet 46 containing the glued product is pushed forward to the turnover trolley 42, the lifting drive cylinder 436 is activated and causes the pallet claw 435 to disengage from the loading pallet 46. Then, the push-pull drive motor 432 drives the drive gear 433 to rotate in the opposite direction, so that the push-pull movable frame 431 moves backward to the initial position.

[0051] Example 3, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 12 As shown, the difference between this embodiment 3 and embodiment 1 is that the turnover trolley 42 includes a trolley frame 421, and the lower end of the trolley frame 421 is equipped with a traveling caster 422.

[0052] The trolley frame 421 is equipped with several support roller groups 423 arranged sequentially from top to bottom, and the trolley frame 421 is equipped with pallet limiting guards on the front, left and right sides of each support roller group 423; the trolley frame 421 is equipped with pallet stop pin assemblies 425 on the rear side of each support roller group 423, and the front end of the lifting platform 41 is equipped with a stop pin unlocking mechanism 45.

[0053] When the turnover trolley 42 of this embodiment is used, the loading pallet 46 is placed on the supporting roller assembly 423, and the supporting roller assembly 423 facilitates the pushing and pulling movement of the loading pallet 46.

[0054] During the process of the pallet push-pull mechanism 43 pulling the loading pallet 46 out from the turnover trolley 42, the stop pin unlocking mechanism 45 is activated and acts on the pallet stop pin assembly 425 to unlock the pallet stop pin assembly 425; after the pallet stop pin assembly 425 is unlocked, the pallet push-pull mechanism 43 is activated and the loading pallet 46 is pulled out.

[0055] Example 4, as Figure 12 As shown, the difference between this embodiment four and embodiment three is that: the pallet stop pin assembly 425 includes a stop pin mounting seat 4251 that is screwed and fastened to the trolley frame 421. The stop pin mounting seat 4251 is vertically slidably mounted with a movable slider 4252 through a guide pair 8. The movable slider 4252 is equipped with a movable stop pin 4253, and a spring 4254 that elastically abuts against the movable slider 4252 is installed between the movable slider 4252 and the stop pin mounting seat 4251.

[0056] The stop pin unlocking mechanism 45 includes a stop pin unlocking drive cylinder 451 installed at the front end of the lifting platform 41 and moving horizontally back and forth. The drive end of the stop pin unlocking drive cylinder 451 is equipped with a wedge-shaped slider pressure block 452.

[0057] When the locking pin unlocking mechanism 45 unlocks the pallet locking pin assembly 425, the lifting drive mechanism 44 drives the lifting platform 41 to move and align the locking pin unlocking mechanism 45 with the corresponding pallet locking pin assembly 425. Then, the locking pin unlocking drive cylinder 451 pushes the slider block 452 forward. The forward-moving slider block 452 presses the movable slider 4252 downward and causes the movable slider 4252 to move downward relative to the locking pin mounting seat 4251. During this process, the spring 4254 is compressed, and the movable locking pin 4253 moves downward synchronously with the movable slider 4252, thereby causing the movable locking pin 4253 to retract from the blocking position of the loading pallet 46.

[0058] When the slider block 452 retracts from the movable slider 4252, the restoring force of the spring 4254 causes the movable slider 4252 to move upward and reset, thereby causing the movable stop pin 4253 to reset to the blocking position of the loading tray 46.

[0059] Example 5, such as Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 12 as well as Figure 13As shown, the difference between this fifth embodiment and the third embodiment is that the car frame 421 is provided with two frame locking rods 4211 that are arranged side by side and spaced apart, and the frame 1 is equipped with an automatic locking mechanism 9 for each frame locking rod 4211.

[0060] The automatic locking mechanism 9 includes a locking fixing block 91 installed on the frame 1. The locking fixing block 91 has a locking groove 92 with a forward opening. A locking drive cylinder 93 is installed on the side of the locking fixing block 91 next to the locking groove 92. A locking block 94 is installed on the drive end of the locking drive cylinder 93.

[0061] It should be noted that during operation, when the turnover trolley 42 moves to the designated position, the two frame locking rods 4211 are respectively inserted into the locking grooves 92 of the corresponding locking fixing blocks 91, and each locking drive cylinder 93 drives the corresponding locking block 94 to move, so that each frame locking rod 4211 is locked in the locking groove 92 of the corresponding side by the locking block 94.

[0062] It should be emphasized that when the turnover trolley 42 moves to the designated position, this embodiment 5 uses the automatic locking mechanism 9 to lock the frame locking rod 4211 of the trolley frame 421 to fix the turnover trolley 42 in the designated position, so as to prevent the turnover trolley 42 from shifting during the feeding operation of the automatic feeding component.

[0063] It should be explained that a through-beam photoelectric sensor can be installed in this embodiment five. This through-beam photoelectric sensor is electrically connected to the controller 100, and the locking drive cylinder 93 in this embodiment five is controlled by the controller 100. When the turnover trolley 42 moves to the designated position, the above-mentioned through-beam photoelectric sensor senses the positioning signal of the turnover trolley 42 and feeds the signal back to the controller 100. Then, the controller 100 controls the locking drive cylinder 93 to operate, so that the locking block 94 locks the frame locking rod 4211 into the locking groove 92.

[0064] Example 6, as Figure 13 As shown, the difference between this embodiment six and embodiment five is that each fixing block is equipped with a guide wheel group 95 on the front side of the corresponding locking groove 92.

[0065] When the turnover trolley 42 is pushed to the designated position, the guide wheel assembly 95 can play a guiding role so that the frame locking rod 4211 of the trolley frame 421 is accurately aligned with the locking groove 92.

[0066] Example 7, as Figure 3 , Figure 6 , Figure 8As shown, the difference between Embodiment Seven and Embodiment One is that the lifting drive mechanism 44 includes a left lifting seat 441 and a right lifting seat 442, which are slidably mounted on the frame 1 via guide pairs 8. A left lifting drive module 443 is mounted on the frame 1 corresponding to the left lifting seat 441, and a right lifting drive module 444, which operates synchronously with the left lifting drive module 443, is mounted on the frame 1 corresponding to the right lifting seat 442. The left lifting drive module 443 is drivenly connected to the left lifting seat 441, and the right lifting drive module 444 is drivenly connected to the right lifting seat 442. The left lifting drive module 443 and the right lifting drive module 444 are electrically connected to the controller 100. During operation, the controller 100 controls the movement of the left lifting drive module 443 and the right lifting drive module 444.

[0067] In addition, the left end of the lifting platform 41 is connected to the left lifting seat 441, and the right end of the lifting platform 41 is connected to the right lifting seat 442.

[0068] During the lifting drive mechanism 44 in this embodiment 7, when it drives the lifting platform 41 to move up and down, the left lifting drive module 443 and the right lifting drive module 444 move synchronously. The left lifting drive module 443 drives the left lifting seat 441 to move up and down, and the right lifting drive module 444 drives the right lifting seat 442 to move up and down. The left lifting seat 441 and the right lifting seat 442 move synchronously, and the left lifting seat 441 and the right lifting seat 442 drive the lifting platform 41 to move up and down.

[0069] Example 8, as Figure 3 and Figure 4 As shown, the difference between this embodiment eight and embodiment one is that: the XY horizontal moving platform 33 includes a Y-axis drive linear module 331 mounted on the upper end of the glue-filling fixing bracket 32 ​​and moving horizontally along the Y-axis direction. The drive end of the Y-axis drive linear module 331 is equipped with a Y-axis movable frame 332. The Y-axis movable frame 332 is equipped with an X-axis drive linear module 333 that moves horizontally along the X-axis direction. The drive end of the X-axis drive linear module 333 is equipped with an X-axis movable frame 334. The CCD industrial camera 34 and the Z-axis drive linear module 35 are respectively mounted on the X-axis movable frame 334.

[0070] Example 9, as Figures 7 to 10 As shown, the difference between this embodiment nine and embodiment one is that the upper surface of the lifting platform 41 is equipped with a number of platform rollers 411 arranged at uniform intervals.

[0071] In addition, the upper surface of the lifting platform 41 is equipped with two pallet baffles 412 arranged at left and right intervals. One pallet baffle 412 is located on the left side of the pallet pushing and pulling mechanism 43, and the other pallet baffle 412 is located on the right side of the pallet pushing and pulling mechanism 43.

[0072] During the process of the pallet push-pull mechanism 43 driving the loading pallet 46 to move back and forth on the lifting platform 41, the platform roller 411 can make the loading pallet 46 move more smoothly and effectively reduce the friction noise when the loading pallet 46 moves.

[0073] When the pallet push-pull mechanism 43 pulls the loading pallet 46 on the turnover trolley 42 onto the lifting platform 41, the two pallet baffles 412 can position the loading pallet 46, thereby ensuring that the loading pallet 46 is located directly below the platform through hole 111 of the fixed platform 11 during the glue dispensing operation.

[0074] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
