[0030] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the embodiments, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0031] Example:

[0032] like Figure 1-8 As shown, the present invention provides an efficient and compact dispensing module, including a dispensing module 1, the dispensing module 1 includes a base 11 and a dispensing head fixedly arranged just above the middle of the base (11), the dispensing head is a gantry-type multi-point dispensing device, which is an existing commercially available device, and its specific structure and working principle are not described in detail.

[0033] Both sides of the top surface of the base 11 (such as Figure 1 Linear modules 3 are fixedly mounted on the front and rear sides (shown in FIG). Two linear modules 3 are arranged parallel to the base 11. The linear modules 3 include guide rails 31 bolted to the top edge of the base 11 and sliding nut sliders 32 adapted to the guide rails 31. The linear modules utilize a ball screw transmission structure driven by a universal stepper motor or servo motor. Their specific structure and operating principle are not detailed here.

[0034] Each guide rail 31 is provided with two nut sliders 32. The top surfaces of the four nut sliders 32 are fixedly mounted with a storage plate 2 located below the dispensing head. By synchronously driving the two sets of linear modules 3, the storage plate 2 can be driven to achieve horizontal reciprocating motion on the guide rail 31, and the motion process is relatively smooth. Preferably, the storage plate 2 is a square plate, and the top ends of the base 11 (such as Figure 1 The left and right ends shown in FIG are fixedly provided with baffles 12 at the end of the sliding stroke of the storage plate 2. Figure 7 As shown, the sliding travel of the storage plate 2 can be limited to prevent excessive sliding and derailment during sliding. At the same time, it facilitates the setting of the starting point for the reverse movement of the storage plate 2, thereby eliminating errors in the linear module transmission. The side of the baffle 12 is equipped with a travel control switch (not shown) that is electrically connected to the drive module of the linear module 3. When the storage plate 2 moves to the extreme travel position at either end, the side of the storage plate 2 abuts the side of the baffle 12, triggering the travel switch and controlling the linear module 3 to pause operation.

[0035] The top surface of the storage plate 2 is symmetrically defined on the left and right ends of the plate. Each set of grooves 21 contains four grooves, equidistantly spaced along the direction of movement of the dispensing head. The contours of each groove 21 are tailored to the workpiece being dispensed, facilitating quick placement and securement. When the storage plate 2 reciprocates to the corresponding travel limits on either side of the linear module 3, the two sets of grooves 21 alternately align directly below the dispensing head.

[0036] A plurality of baffles 22 are arranged at equal intervals on the inner bottom of the groove 21, and a movable cavity 23 is formed between every two baffles 22 and extends to the bottom of the storage plate 2. After the workpiece to be glued is placed in the groove 21, the bottom surface of the workpiece is in contact with the top surface of the baffle 22, and the four sides of the workpiece are in contact with the four side walls of the groove 21, so that the placement position of the workpiece in the groove 21 for glueing can be quickly determined, thereby ensuring the accuracy of the subsequent glueing position.

[0037] Preferably, both the storage plate 2 and the lever 22 are shell structures with internal cavities. In this embodiment, the storage plate 2 and lever 22 form an integral, sealed cavity structure. The lever 22 has several air holes 221 on the side facing away from the linear module 3 (i.e., the top surface), which communicate with the cavity of the storage plate 2. A connecting tube 24 for connection to a vacuum machine is provided on one side of the storage plate 2. During the dispensing operation, the internal pressure of the storage plate 2 is maintained by an external vacuum machine, and the workpiece positioned within the groove 21 is adsorbed therein by the negative pressure.

[0038] On both sides of the top surface of the base 11, there are respectively provided workpiece lifting devices 4 located below the grooves 21. When the storage plate 2 moves back and forth to the corresponding limit travel positions on both sides of the linear module 3, the two workpiece lifting devices 4 are alternately located directly below the grooves 21 on the same side. Therefore, the two workpiece lifting devices 4 are symmetrically arranged on the left and right sides of the dispensing head, and the center distance between the two workpiece lifting devices 4 is twice the center distance between the two groups of grooves 21. When the storage plate 2 is at the limit travel position at the left end, the left group of grooves 21 is located directly above the left workpiece lifting device 4, and the right group of grooves 21 is located directly below the dispensing head; when the storage plate 2 is at the limit travel position at the right end, the right group of grooves 21 is located directly above the right workpiece lifting device 4, and the left group of grooves 21 is located directly below the dispensing head.

[0039] The workpiece lifting device 4 includes a motor 44 fixedly mounted vertically on the top surface of the base 11, a screw 45 fixedly connected to the output shaft end of the motor 44, and a base plate 41 threadedly connected to the outer side of the top of the screw 45. A plurality of strips 42 adapted to the movable cavity 23 are fixedly mounted on the side of the base plate 41 close to the groove 21. The screw 45 is driven to rotate by the forward / reverse rotation of the motor 44, and the base plate 41 is driven to rise / fall by the thread transmission. The motor 44 adopts a stepping motor or a servo motor to accurately set and control the unidirectional stroke of the base plate 41. A movable hole 412 is provided at the bottom of the base plate 41, and a guide rod 43 adapted to the movable hole 412 is fixedly mounted on the base 11. The cooperation between the guide rod 43 and the movable hole 412 guides the lifting and lowering of the base plate 41.

[0040] The upper end of the strip 42 is positioned below the storage plate 2, and the top of the workpiece lifting device 4 can be inserted into the corresponding groove 21. That is, the strip 42 can pass through the movable cavity 23 and enter the groove 21. The vertical lifting height of the strip 42 is greater than the thickness of the storage plate 2. This allows the strip 42 to vertically eject the workpiece in the groove 21 and position it above the top surface of the storage plate 2, facilitating rapid removal and transfer of the workpiece. When the strip 42 is lowered to its lowest position, it is below the storage plate 2 and does not interfere with the horizontal movement of the storage plate 2.

[0041] The use of the device is described by taking the storage plate 2 at the left end as an example.

[0042] First, place the workpieces inside the grooves 21 of the left group, and connect the connecting pipe 24 to the vacuum machine. When the vacuum machine is running, the inside of the cavity can be negatively pressurized, and then under the action of the air holes 221, the workpiece is adsorbed and fixed inside the grooves 21. Then, the linear module 3 drives the placement plate 2 to move horizontally to the right by a single preset distance (i.e., the middle distance between the two groups of grooves 21, which is the maximum one-way stroke of the placement plate 2 in this embodiment), so that the placement plate 2 is located at the right extreme position, and the linear module 3 stops working. At this time, the grooves 21 of the left group are located below the dispensing module 1, and the empty grooves 21 of the right group are located at the right extreme position. The dispensing head dispenses glue on the workpiece inside the grooves 21 below it, and a new workpiece can be placed in the empty groove 21 on the right.

[0043] When the glue is dispensed, the linear module 3 drives the storage plate 2 to move to the left to the limit position. At this time, the workpiece with glue dispensed is located directly above the workpiece lifting device 4 on the left, and the new workpiece in the groove 21 on the right is located directly below the glue dispensing head. The workpiece lifting device 4 on the left works, and the vacuum machine stops running. The motor 44 on the corresponding side drives the corresponding strip 42 to rise, and the workpiece with glue dispensed in the left groove 21 is ejected. This makes it easy to manually and quickly remove the workpiece with glue dispensed. Then the motor 44 in the workpiece lifting device 4 on the left works in the reverse direction, causing the strip 42 to descend to the initial position. At this time, the worker can put a new workpiece to be glued into the controlled groove 21 again, and the vacuum machine works again. At the same time, the glue dispensing head performs the glue dispensing operation on the workpiece in the right groove 21. After the glue dispensing operation is completed, the storage plate 2 can be driven to the right again to the limit travel position on the right side, and the removal of the glued workpiece and the placement of the new workpiece on the right side are completed. Repeating the above process allows the worker to replace the workpiece on the side away from the dispensing head, and the workpiece lifting device 4 facilitates rapid replacement, thereby improving dispensing efficiency and making replacement more compact.
