Description

Technical Field

[0002] The bottom cover in a thermos cup is located in the middle of the bottom end of the thermos cup, and is used to seal the bottom of the thermos cup and form a vacuum with the inner liner of the thermos cup. Therefore, the welding of the bottom cover of the thermos cup is the key to realizing the heat preservation function of the thermos cup. The existing bottom cover welding basically still relies on manual labor, including the taking of materials and the adjustment of the welding position due to the height problem of the incoming bottom cover, but manual production affects the production efficiency.

The welding between the bottom cover and the cup body is prone to defects, which directly affects the heat preservation effect of the thermos cup and easily increases the defective rate. To solve the automatic processing of the bottom cover, as disclosed in the welding mechanism of the patent No. CN217045015U, the bottom cover can be welded, but it cannot eliminate the influence of the tolerance of the bottom cover and still requires manual operation for adjustment.

[0023] As Figure 1 shown, the present utility model discloses a fully automatic bottom cover welding device, which includes a frame 101, a protective cover 102, a control host 4, a positioning mechanism, a welding mechanism, and a welding adjustment mechanism. The protective cover 102 is fixedly arranged on the frame 101, the control host 4 is arranged on one side of the frame 101. The positioning mechanism includes a rotating seat 201, a rotating motor, a pressing member 202, and a pressing drive mechanism. The rotating seat 201 is rotatably arranged on the frame 101 and is driven to rotate by the rotating motor. The pressing member 202 is coaxially arranged above the rotating seat 201 and is driven by the pressing drive mechanism to move up and down relative to the rotating seat 201. A positioning space for positioning the welding part is formed between the rotating seat 201 and the pressing member 202. The welding mechanism includes a laser gun head 501 and a laser 5 which are connected. The laser 5 is arranged on one side of the frame 101. The welding adjustment mechanism includes a CCD camera 301, a connecting block 302, and a three-way adjusting rod 303. The laser gun head 501 is fixedly arranged on the connecting block 302. The connecting block 302 is slidably arranged on the three-way adjusting rod. The three-way adjusting rod and the CCD camera 301 are respectively arranged on the frame 101. The control host 4 detects the position of the welding part in real time through the CCD camera 301 and adjusts the welding position of the gun head of the laser gun head 501 to match the welding part by controlling the movement of the three-way adjusting rod.

[0024] In this solution, the CCD camera 301 is set to detect the height of the laser gun head 501 in real time, and the three-way adjusting rod is used to adjust the position of the laser gun head 501 to ensure the matching of the welding position between the laser gun head 501 and the welding part, eliminate the influence of the tolerance of the bottom cover, and realize the fully automatic welding process between the bottom cover and the cup body while ensuring the accuracy and reliability of welding.

[0025] Specifically, the rotating seat 201 is rotatably disposed on the frame 101 via a bearing, and the rotating motor is disposed in the frame 101 , and its motor shaft is fixedly connected to the bottom of the rotating seat 201 to drive the rotating seat 201 to rotate.

[0026] The pressing drive mechanism includes a connecting bracket 203, a driving screw 204, a first servo motor 205 and a sliding plate 206. The connecting bracket 203 is fixed on the frame 101. The first servo motor 205 is fixed on the top of the connecting bracket 203. The first servo motor 205 is connected to the driving screw 204 in a transmission manner. The driving screw 204 is vertically penetrated in the connecting bracket 203. The axis of the sliding plate 206 is screwed on the driving screw 204, and the corners of the sliding plate 206 are slidably penetrated on the connecting bracket 203. The pressing member 202 is arranged at the bottom of the sliding plate 206 and slides up and down synchronously with the sliding plate 206. The first servo motor 205 drives the driving screw 204 to rotate so that the sliding plate 206 slides up and down along it, so as to achieve the purpose of driving the pressing member 202 to rise and fall, and cooperate with the rotating seat 201 to limit the welding parts.

[0027] The welding parts in this scheme are preferably a bottom cover and a cup body. The cup body is sleeved on the rotating seat 201, and the bottom cover is mounted on the rotating seat 201. The pressing member 201 presses down to tighten the bottom cover and the cup body. The pressing member 202 is a cone with an outer diameter that gradually decreases from top to bottom, so as to minimize the contact area between it and the bottom cover and reduce the wear on the bottom cover. The pressing member 202 is pivoted at the bottom of the sliding plate 206. Such a structure allows the pressing member 202 to limit the welding part in the vertical direction without hindering the rotation of the welding part, thereby facilitating the laser gun head to perform circumferential welding on the welding part.

[0028] like Figure 1As shown in the figure, the three-way adjusting rod includes a first screw rod 3031, a second screw rod 3032, and a third screw rod 3033.

The bottom of the second screw rod 3032 is screwed onto the first screw rod 3031 and moves horizontally along it. The third screw rod 3033 is horizontally arranged and perpendicular to the extension direction of the first screw rod 3031. The third screw rod 3033 is screwed onto the second screw rod 3032 and moves vertically along it. The connecting block 302 is screwed onto the third screw rod 3033. The laser gun head 501 determines the position of its gun head in the vertical direction through the second screw rod 3032, and determines the position of its gun head in the horizontal direction through the first screw rod 3031 and the third screw rod 3033, so as to ensure that the position of the gun head of the laser gun head 501 always matches the welding position of the welded part to the greatest extent, and is not affected by the height tolerance of the welded part.

[0029] Furthermore, an adjusting bracket 305 is vertically arranged on the frame 101, and the CCD camera 301 is movably arranged on the adjusting bracket 305. The CCD camera 301 can move up and down along the adjusting bracket 305 to adjust its height to ensure the accuracy of detection.

[0030] In addition, safety light curtains 104 are arranged on both sides of the front side of the frame 101, and a protective door 103 is arranged at the bottom of the frame 101. The height of the protective door 103 is not lower than the height of the gun head of the laser gun head 501. The settings of the safety light curtains 104 and the protective door 103 can ensure that it is closed when the laser gun head 501 is in the working state, avoid accidentally injuring the operator, and improve the use safety.

[0031] Furthermore, a computer display screen 401 is arranged on one side of the frame 101. The computer display screen 401 is connected to the control host 4 to display the operation status in real time, facilitating the visual management of the operator.

[0032] Similarly, control buttons 6 are arranged on both sides of the front side of the frame 101, which is convenient for the operator to operate with both hands. A human-machine interface 601 is arranged on one side of the frame 101. The human-machine interface 601 is connected to the control buttons 6 to facilitate operation.

[0033] Anchor bolts 7 are also arranged at the bottom of the frame 101 to adjust the height of its bottom to adapt to the uneven bottom surface and ensure the placement stability.
