Description

Technical Field

[0001] This invention relates to the field of watch case manufacturing technology, and more specifically to a transfer mechanism for watch case manufacturing. Background Technology

[0002] The watch case usually refers to the outer casing of the watch body (watch head). Its function is to install and fix the various parts of the watch that are used for operation, and to protect the internal parts of the watch (movement, dial, hands, etc.) from damage such as impacts that would cause them to stop working. This allows the watch to maintain its basic operation. Therefore, the watch case is a relatively important protective and mounting part of the watch.

[0003] The main production process of a watch case begins with designing the case's shape. Then, using the corresponding raw materials, the case is initially machined into a basic shape using stamping and cutting techniques. Next, the shaped case is transferred to a polishing device for further polishing. This process creates a beautiful and practical watch case that protects the internal components of the watch from damage while enhancing its overall appearance. As stamping, cutting, and polishing techniques have become increasingly sophisticated, the production speed of watch cases has improved significantly. However, after completing one process, the case needs to be moved to another process for further processing.

[0004] This work method has several drawbacks. First, it requires constant attention to transfer the watch case to the next process after completing the previous one. This necessitates frequent back-and-forth movement between processes, which is physically demanding and can affect work efficiency. Second, watch cases are often thin and, sometimes, made to fit comfortably, are not very rigid. During transfer, multiple watch cases are prone to collisions, resulting in scratches or other defects and reducing the overall appearance quality of the finished watch, leading to poor watch case quality. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a transfer mechanism for watch case production. This mechanism solves the problems mentioned in the background art, where after completing one process of watch case production, the processing personnel need to transport the watch case to the next process, thus affecting processing efficiency. Additionally, the transfer process of the watch case can easily cause damage to the watch case surface.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a transfer mechanism for watch case production, comprising two transfer frames arranged between two watch case production processes, and further comprising:

[0009] The transfer drive belt has two belts, each rotatably connected to one end of two transfer moving frames. Each belt has multiple mounting components, and a transfer box is provided between two corresponding mounting components. A drive component is provided between the two belts to drive the two belts to move the multiple transfer boxes.

[0010] A control component is disposed inside the corresponding transfer box and is used to control the watch cases placed in the transfer box to prevent collisions between multiple watch cases. A moving component is provided between the control component and the transfer box.

[0011] The fixing components are multiple in number, and each fixing component is disposed on the top of a corresponding transport box for fixing the upper side of the watch case placed inside the transport box.

[0012] A stabilizing component is disposed on one side of one of the corresponding ends of the two transfer frames to stabilize the two transfer drive belts and prevent them from moving excessively.

[0013] To securely mount the transfer box between two fixed frames, so that the transfer conveyor belt rotates and drives the transfer box to move, preferably, the mounting assembly includes a fixed frame. The fixed frame is fixedly connected to one end of one of the transfer conveyor belts near the transfer box. A fixed plate is slidably connected inside the fixed frame. Supporting platforms are provided on both the front and rear sides of the transfer box. Multiple elastic components are provided between the fixed plate and the inner wall of the fixed frame. A portion of the fixed plate away from the fixed frame is located between the inner wall of the support platform. Multiple sliding openings are correspondingly provided between the support platform and the fixed plate. A fixed rod is slidably arranged between two corresponding sliding openings. Threaded sections are provided at both ends of the fixed rod, and nuts are threadedly connected to both threaded sections.

[0014] In order to drive the two transfer belts to rotate and move the multiple transfer boxes, the drive assembly further includes multiple drive wheels. The two transfer belts are arranged between the outer sides of the corresponding multiple drive wheels. A rotating shaft is arranged between two corresponding drive wheels. A motor is installed at the front end of one of the transfer frames, and the output end of the motor is fixedly connected to one of the rotating shafts.

[0015] To further control the watch case placed in the placement slot and prevent it from moving arbitrarily, the control component includes a control board with multiple placement slots. Push plates are slidably connected between the inner walls of the multiple placement slots, and a mounting rod is fixedly connected to the top of the push plate. Multiple clamping parts are provided on the mounting rod.

[0016] To control the multiple push plates and move them up and down in their corresponding slots for easy placement and removal of the watch case, as a further embodiment of this solution, the moving component includes an electric cylinder. Each of the multiple transfer boxes has a mounting port at its bottom, and the electric cylinder is installed in the corresponding mounting port. Each of the multiple push plates has a connecting rod fixedly connected to its bottom. A connecting plate is fixedly connected between the bottom ends of two connecting rods on the same side. The multiple connecting plates are fixedly connected to each other via multiple joint plates. The output end of the electric cylinder is fixedly connected to the bottom end of one of the joint plates.

[0017] To secure the upper part of the watch case and prevent it from being ejected from the placement slot by a connecting strap, while also preventing other objects from entering the placement slot and damaging it, as a further solution, the fixing component includes two buckles, which are respectively located at the front and rear ends of the transport box. A connecting strap is provided between the two buckles, and sliding openings are provided on both sides of the top of the transport box corresponding to the connecting strap. The connecting strap is slidably positioned between two corresponding sliding openings.

[0018] In order to enable emergency braking and rapid stabilization when the conveyor belt stops rotating, based on the aforementioned scheme, the stabilizing component includes two mounting plates and two arc-shaped plates. The two mounting plates are fixedly connected between corresponding ends of the two conveyor frames, and the two mounting plates are located on both sides of one of the rotating shafts. Each of the two mounting plates has a fixing opening, in which an electric cylinder is installed. Each of the two arc-shaped plates has a stabilizing plate at its corresponding end. The output end of the electric cylinder is fixedly connected to the corresponding arc-shaped plate, and the stabilizing plate is located on the left and right sides of one of the rotating shafts.

[0019] In order to push the fixed plate into the corresponding support platform and facilitate the fixing and disassembly of the transfer box, based on the aforementioned solution, the elastic component further includes a damping rod, which is disposed between the inner sidewall of the fixed plate and the fixed frame, and is parallel to the inner bottom wall of the fixed frame. A spring is sleeved on the outer side of the damping rod.

[0020] In order to further secure the watch case placed on the push plate to the outside of the mounting rod, based on the aforementioned solution, the clamping member includes a clamping plate, the mounting rod is provided with multiple sliding grooves, the clamping plate is slidably connected to the inner wall of the corresponding sliding groove, and multiple springs are provided between the clamping plate and the inner wall of the sliding groove, and the multiple springs are parallel to the inner bottom wall of the sliding groove.

[0021] To provide fixed support for the two transfer frames, an optimized version of the aforementioned solution is provided, in which multiple support legs are fixedly connected to the bottom of each of the two transfer frames.

[0022] (III) Beneficial Effects

[0023] Compared with known public technologies, the present invention provides a transfer mechanism for watch case production, which has the following beneficial effects:

[0024] In this invention, a transfer conveyor belt is provided at one end of each of the two transfer frames, and both transfer conveyor belts are fixed to the transfer box through the mounting components. This facilitates the fixed installation of the transfer box between the two fixed frames, so that the transfer conveyor belts can rotate to drive the transfer box to move. Furthermore, a control component is provided inside the corresponding transfer box to control the watch case placed in the placement slot and prevent it from moving randomly. A moving component is provided between the control component and the transfer box to control multiple push plates, so that they can rise and fall in the corresponding placement slots. This facilitates the placement and removal of watch cases, thereby quickly completing the transfer of multiple watch cases while providing excellent protection.

[0025] By setting a fixing component on the top of the corresponding transfer box, it is easy to fix the upper part of the watch case. The connecting belt prevents the watch case from rushing out of the placement slot and prevents other objects from entering the placement slot and damaging it. By setting a stabilizing component on one side of one of the corresponding ends of the two transfer moving frames, it is easy to brake it in an emergency when the transfer conveyor belt stops rotating, so that it can quickly maintain stability.

[0026] Therefore, the watch case production transfer mechanism can be set between two processes to quickly transfer the watch case after one process is completed to the next process, thereby improving the production efficiency of the watch case. In addition, it can effectively fix and protect the watch case during the transfer process to prevent damage. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, please refer to Figure 1 and Figure 2 A transfer mechanism for watch case production includes two transfer frames 1. The two transfer frames 1 are positioned between two watch case production processes and correspond to each other. The bottom of each of the two transfer frames 1 is fixedly connected to multiple support legs 4. By positioning the two transfer frames 1 between two processes required in the watch case production process, such as between a cutting machine and a polishing machine, after the watch case raw material has been processed into a general shape by the cutting machine, it needs to be transferred to the polishing machine for fine polishing to make its shape more rounded and beautiful. Therefore, by positioning the two transfer frames 1 between the two processes, the watch case can be quickly transferred to the polishing machine after the cutting process is completed to continue the polishing operation.

[0037] Please see Figure 1 , Figure 2 and Figure 6There are two transfer conveyor belts 2, each rotatably connected to one end of a corresponding transfer moving frame 1. Multiple mounting components 100 are provided on each of the two transfer conveyor belts 2. Each mounting component 100 includes a fixing frame 101, which is fixedly connected to one end of one of the transfer conveyor belts 2 near the transfer box 3. A fixing plate 102 is slidably connected inside the fixing frame 101. Support platforms 103 are provided on both the front and rear sides of the transfer box 3. Multiple elastic components 700 are provided between the fixing plate 102 and the inner wall of the fixing frame 101. Each elastic component 700 includes a resistance... A damping rod 701 is disposed between the inner wall of the fixed plate 102 and the fixed frame 101, and the damping rod 701 is parallel to the inner bottom wall of the fixed frame 101. A spring 702 is sleeved on the outer side of the damping rod 701. A portion of the fixed plate 102 away from the fixed frame 101 is disposed between the inner wall of the support platform 103. Multiple sliding openings are correspondingly provided between the support platform 103 and the fixed plate 102. A fixed rod 104 is slidably disposed between two corresponding sliding openings. Both ends of the fixed rod 104 are provided with threaded sections, and nuts are threadedly connected to both threaded sections. A transfer box 3 is provided between corresponding mounting components 100, and a drive assembly 200 is provided between two transfer belts 2 for driving the two transfer belts 2 to move multiple transfer boxes 3. The drive assembly 200 includes multiple drive wheels 201, and the two transfer belts 2 are respectively located between the outer sides of the corresponding multiple drive wheels 201. A rotating shaft 202 is provided between two corresponding drive wheels 201. A motor 203 is installed at the front end of one of the transfer frames 1, and the output end of the motor 203 is fixedly connected to one of the rotating shafts 202. Multiple watch cases are placed in the corresponding transfer boxes. After step 3, the start motor 203 drives one of the rotating shafts 202 to rotate, which in turn drives multiple drive wheels 201 on both sides to rotate, thereby causing the two transfer belts 2 to rotate. This causes the transfer box 3 to move to one side, thus transferring multiple watch cases to the machine on the other side. When it is necessary to remove the transfer box 3, first loosen the fixing rod 104 to fix the fixing plate 102 and the support platform 103. Then, the fixing plate 102 is temporarily retracted into the inner wall of the fixing frame 101 by the compression spring 702 and the damping rod 701. Then, the transfer box 3 is taken out.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The control component 300 is located inside the corresponding transfer box 3 and is used to control the watch cases placed in the transfer box 3 to prevent collisions between multiple watch cases. A moving component 400 is provided between the control component 300 and the transfer box 3. The control component 300 includes a control plate 301, which has multiple placement slots. Push plates 302 are slidably connected between the inner walls of the multiple placement slots. A mounting rod 303 is fixedly connected to the top of the push plate 302. Multiple clamping members 800 are provided on the mounting rod 303. Each clamping member 800 includes a clamping plate 801. Multiple sliding grooves are provided on the mounting rod 303. The clamping plate 801 is slidably connected to the inner wall of the corresponding sliding groove. Multiple springs 802 are provided between the clamping plate 801 and the inner wall of the sliding groove. All springs 802 are parallel to the inner bottom wall of the sliding groove. The moving component 400 includes an electric cylinder 401. The bottom of the multiple transfer boxes 3 Each end is provided with an installation port, and the electric cylinder 401 is installed in the corresponding installation port. The bottom ends of multiple push plates 302 are fixedly connected to connecting rods 402. A connecting plate 403 is fixedly connected between the bottom ends of two connecting rods 402 on the same side. Multiple connecting plates 403 are fixedly connected to each other by multiple joint plates 404. The output end of the electric cylinder 401 is fixedly connected to the bottom end of one of the joint plates 404. After a certain number of watch cases have been processed by cutting operations, they are quickly placed in the corresponding placement slots. Then, the spring 802 pushes the clamping plate 801 to generate a clamping force on the inner wall of the watch case, thereby fixing the watch case in the placement slot. When it is necessary to remove the watch case from the placement slot, the electric cylinder 401 is activated to push the joint plate 404, thereby raising the connecting plate 403 and the connecting rod 402, thus driving the watch case to rise, lifting the watch case from the placement slot, and then removing it.

[0039] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 There are multiple fixing components 500, each set on the top of a corresponding transfer box 3, used to fix the upper side of the watch case placed inside the transfer box 3. Each fixing component 500 includes two buckles 501, which are respectively set at the front and rear ends of the transfer box 3. A connecting strap 502 is provided between the two buckles 501. Sliding openings are provided on both sides of the top of the transfer box 3 corresponding to the connecting strap 502. The connecting strap 502 is slidably set between the two corresponding sliding openings. After the placement slot in the control board 301 of one of the transfer boxes 3 is filled with the watch case, multiple elastic connecting straps 502 are then connected between the corresponding two buckles 501 to fix the upper part of the watch case. The connecting straps 502 prevent the watch case from rushing out of the placement slot and prevent other objects from entering the placement slot and damaging it.

[0040] Please see Figure 1 and Figure 2 A stabilizing component 600 is disposed on one side of one of the corresponding ends of the two transfer frames 1 to stabilize the two transfer belts 2 and prevent them from moving excessively. The stabilizing component 600 includes two mounting plates 601 and two arc-shaped plates 602. The two mounting plates 601 are fixedly connected between the corresponding ends of the two transfer frames 1 and are located on both sides of one of the rotating shafts 202. Each of the two mounting plates 601 has a fixing port, in which an electric cylinder 603 is installed. Each of the two arc-shaped plates 602 has a stabilizing plate 604 at one of the corresponding ends. The output end of the electric cylinder 603 is fixedly connected to the corresponding arc-shaped plate 602. The stabilizing plates 604 are disposed on the left and right sides of one of the rotating shafts 202. When the two transfer belts 2 move one of the transfer boxes 3 to the designated position, the two electric cylinders 603 are activated to push the corresponding arc-shaped plate 602, thereby causing the two stabilizing plates 604 to rub against the sides of the corresponding rotating shaft 202, making it quickly stabilized and preventing the two transfer belts 2 from rotating too far.

[0041] In Example 2, the watch case production transfer mechanism, when in use, firstly, two transfer frames 1 are set between the cutting machine and the grinding machine. Then, after a certain number of watch cases have been processed by cutting, they are quickly placed in their corresponding placement slots. Next, spring 2 802 pushes the clamping plate 801 to generate a clamping force on the inner wall of the watch case, thus fixing the watch case in the placement slot. When it is necessary to remove the watch case from the placement slot, electric cylinder 1 401 is activated to push the connecting plate 404, causing the connecting plate 403 and connecting rod 402 to rise, thereby lifting the watch case from the placement slot. The watch case is then removed. After filling the placement slot in the control plate 301 of one of the transfer boxes 3 with watch cases, multiple elastic connecting straps 502 are connected between two corresponding buckles 501 to secure the upper part of the watch case. The connecting straps 502 prevent the watch case from rushing out of the placement slot and also prevent other objects from entering the placement slot. To disrupt the process, after placing multiple watch cases into their respective transfer boxes 3, the motor 203 is started to drive one of the rotating shafts 202 to rotate, which in turn drives multiple drive wheels 201 on both sides to rotate, thereby causing the two transfer belts 2 to rotate. This causes the transfer box 3 to move to one side, thus transferring the multiple watch cases to the machine on the other side. When it is necessary to remove the transfer box 3, firstly, the fixing rod 104 is loosened from the fixing plate 102 and the support platform 103. Then, the fixing plate 102 is temporarily retracted into the inner wall of the fixing frame 101 by the compression spring 702 and the damping rod 701. Next, the transfer box 3 is removed. When the two transfer belts 2 move one of the transfer boxes 3 to the designated position, the two electric cylinders 603 are started to push the corresponding arc plate 602, so that the two stabilizing plates 604 rub against the two sides of the corresponding rotating shaft 202, making it quickly stabilized and preventing the two transfer belts 2 from rotating too far.
