Description

Technical Field

[0001] This utility model belongs to the technical field of dispensing machines, and in particular relates to a rotary tooling for dispensing machines. Background Technology

[0002] Dispensing technology, as a crucial step in modern precision manufacturing, is widely used in the packaging, bonding, and sealing processes of industries such as electronics, semiconductors, and automotive parts. The level of automation of the dispensing machine and the performance of the tooling fixtures directly determine the quality, efficiency, and consistency of the dispensing operation. During dispensing operations, the core issue for improving dispensing process quality is how to stably and accurately fix the workpiece and efficiently complete the coating of complex structures or multiple surfaces.

[0003] Existing technologies and similar rotary fixtures still have several significant drawbacks. First, workpiece clamping often employs simple fixed or unidirectional pneumatic clamping, which lacks stability and reliability for workpieces with special shapes or requiring precise positioning. During high-speed rotation or dispensing head movement, this can easily lead to slight workpiece movement or displacement, affecting the accuracy of the dispensing path. Second, such fixtures typically only have rotational functionality and lack the ability to perform precise horizontal position adjustments. This means the dispensing head must handle all path planning, resulting in low processing efficiency and poor equipment flexibility for workpieces requiring multi-point, multi-position dispensing on a single surface. Therefore, we provide a rotary fixture for dispensing machines to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary fixture for a dispensing machine. Through the cooperation of the movable fixture and the positioning fixture, the stability of the dispensing operation on the workpiece is ensured, and the workpiece can be fully dispensed in both the forward and reverse directions. At the same time, the cooperation of the lead screw and the L-shaped plate facilitates the precise dispensing operation on the workpiece, thereby improving the dispensing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a rotary fixture for a dispensing machine, comprising an L-shaped plate; a positioning clamp is provided on the front end face of the L-shaped plate, and a movable clamp is provided on the front end face of the positioning clamp; a rotary cylinder is fixed in the middle of the end face of the L-shaped plate; a telescopic cylinder is fixed on the outer wall of the positioning clamp; a mounting plate is fixed on the rear end face of the positioning clamp and bolted to the rotating end of the rotary cylinder; a U-shaped plate is provided directly below the L-shaped plate; a lead screw is provided on the inner wall of the U-shaped plate; a motor connected to the lead screw drive is fixed on the outer wall of the U-shaped plate; and a movable plate is fixed on the lower end face of the L-shaped plate and moves in coordination with the ball bearing seat of the lead screw.

[0006] The present invention is further configured such that both ends of the movable clamp are fixed with lugs, one of which is bolted to the piston end of the telescopic cylinder.

[0007] The present invention is further configured such that a protrusion is fixed on the lower part of the inner wall of the positioning fixture, and a movable rod is fixed on the other ear block relative to the end face of the positioning fixture. A movable hole is opened on the end face of the positioning fixture near the movable rod, and the movable rod is slidably inserted into the movable hole.

[0008] The present invention is further configured such that a transfer block is fixed to the rear end face of the L-shaped plate, an air pipe is connected to the rear port of the telescopic cylinder, and the other end of the air pipe is connected to the interior of the transfer block. Both the transfer block and the rotary cylinder are connected to an external air source through pipes.

[0009] The present invention is further configured such that a positioning plate is bolted to the side wall of the positioning fixture on the same side as the telescopic cylinder, and positioning holes are provided through the surface of the positioning plate at the positions corresponding to the air pipe.

[0010] The present invention is further configured such that the middle part of the trachea is corrugated and the corrugated part is located in the positioning hole.

[0011] This utility model has the following beneficial effects: 1. This utility model uses a telescopic cylinder and a rotary cylinder in combination. The telescopic cylinder controls the movable fixture to connect with the positioning fixture, so that the workpiece is clamped. At the same time, the rotary cylinder controls the positioning fixture to rotate, which will drive the workpiece to rotate synchronously. Through the cooperation of the two sets of structures, the stability of the dispensing workpiece can be guaranteed, and the dispensing of glue to the workpiece in both the forward and reverse directions can be achieved.

[0012] 2. This utility model controls the rotation of the lead screw by a motor, thereby controlling the movement of the movable plate, thus realizing the function of adjusting the position plane of the L-shaped plate, facilitating precise dispensing of adhesive to the workpiece and improving dispensing efficiency.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1 to 5 This utility model is a rotary fixture for a dispensing machine, including an L-shaped plate 1; a positioning clamp 2 is provided on the front end face of the L-shaped plate 1, and a movable clamp 201 is provided on the front end face of the positioning clamp 2; a rotary cylinder 101 is fixed in the middle of the end face of the L-shaped plate 1; and a telescopic cylinder 4 is fixed on the outer wall of the positioning clamp 2. The rotary cylinder 101 and the telescopic cylinder 4 work together to assemble the workpiece between the positioning clamp 2 and the movable clamp 201. The positioning clamp 2 and the movable clamp 201 limit the workpiece, allowing the workpiece to rotate according to the rotation of the positioning clamp 2, ensuring the accuracy of subsequent dispensing of the workpiece. At the same time, the rotary cylinder 101 can control the positioning clamp 2 to rotate 180°, thereby realizing the dispensing of the workpiece on both sides. The rear end face of the positioning clamp 2 is fixed with a mounting plate 202 bolted to the rotating end of the rotary cylinder 101. A U-shaped plate 3 is located directly below the L-shaped plate 1. A lead screw 301 is installed on the inner wall of the U-shaped plate 3. A motor 302, which is connected to the lead screw 301, is fixed on the outer wall of the U-shaped plate 3. A movable plate 102, which is moved and cooperates with the ball bearing seat of the lead screw 301, is fixed on the lower end face of the L-shaped plate 1. The motor 302 controls the rotation of the lead screw 301, thereby controlling the movement of the movable plate 102. This enables the L-shaped plate 1 to be adjusted in position and plane, facilitating the comprehensive dispensing of adhesive to the workpiece.

[0022] Specifically, both ends of the movable clamp 201 are fixed with lugs 207, one of which is bolted to the piston end of the telescopic cylinder 4. A protrusion 203 is fixed to the lower part of the inner wall of the positioning clamp 2. When a workpiece is placed inside the movable clamp 201 and the positioning clamp 2 using the protrusion 203, the protrusion 203 initially limits the workpiece to the inner position of the positioning clamp 2. Therefore, after the movable clamp 201 retracts, the positioning clamp 2 will clamp the workpiece tightly within it. The internal position of the positioning fixture 2 is used to ensure the stability of the workpiece position. Another lug 207 has a movable rod 208 fixed to the end face of the positioning fixture 2. The end face of the positioning fixture 2 near the movable rod 208 has a movable hole 206. The movable rod 208 is slidably inserted into the movable hole 206. Through the cooperation of the movable rod 208 and the movable hole 206, the connection between the positioning fixture 2 and the movable fixture 201 can be ensured to be stable, so that the gap between the end faces of the positioning fixture 2 and the movable fixture 201 will not be excessively expanded. Furthermore, according to Figure 2 and Figure 3 It can be seen that a transfer block 403 is fixed on the rear end face of the L-shaped plate 1, and an air pipe 401 is connected to the rear port of the telescopic cylinder 4. The other end of the air pipe 401 is connected to the interior of the transfer block 403. The transfer block 403 and the rotary cylinder 101 are both connected to an external air source through pipes. The telescopic cylinder 4 and the rotary cylinder 101 can be controlled to work through the external air source equipment, so that the telescopic cylinder 4 can control the movement of the positioning fixture 2, and the rotary cylinder 101 controls the positioning fixture 2 to rotate.

[0023] Furthermore, according to Figure 2 and Figure 4 It can be seen that the positioning clamp 2 on the same side of the telescopic cylinder 4 is bolted to a positioning plate 204. The surface of the positioning plate 204 is provided with positioning holes 205 at the positions corresponding to the air pipe 401. The middle part of the air pipe 401 is provided with a corrugated part 402, and the corrugated part 402 is located in the positioning hole 205. The positioning plate 204 limits the air pipe 401, so that the air pipe 401 will not swing at will. At the same time, the surface of the air pipe 401 is provided with a corrugated part 402. Therefore, the positioning clamp 2 will pull the corrugated part 402 of the air pipe 401 during the rotation process, so that the air pipe 401 will be extended, so that the positioning clamp 2 can rotate normally 180°.

[0024] The operation process of this embodiment is as follows: First, the workpiece is placed inside the positioning fixture 2, and the telescopic cylinder 4 is controlled to work. The telescopic cylinder 4 controls the movable fixture 201 to move and abut against the positioning fixture 2, thereby clamping the workpiece. Then, the rotary cylinder 101 is controlled to work, and the rotary cylinder 101 controls the positioning fixture 2 to rotate. The rotation angle of the rotary cylinder 101 can be controlled by the external air source device to perform glue application on the back of the workpiece. At the same time, after the motor 302 is controlled to work, the motor 302 drives the lead screw 301 to rotate. The lead screw 301 moves linearly inside the U-shaped plate 3 through the movable plate 102, thereby moving the L-shaped plate 1 and adjusting the position of the workpiece.
